Special Report

Highlights The selloff in crypto-currencies on May 19 may be overblown but the risk of government intervention is a rising headwind for this asset class. While environmental concerns are a threat to Bitcoin, the entire crypto-currency complex faces a looming confrontation over governance. Digital currencies are a natural evolution of money following coinage and paper. Moreover a sizable body of consumers is skeptical of governments and traditional banking. Loose monetary conditions are fueling a speculative mania. However, governments fought for centuries to gain a monopoly over money. As crypto-currencies become more popular, governments will step in to regulate and restrict them. Central bank digital currencies (CBDCs) threaten to remove the speed and transactional advantage of crypto-currencies, leaving privacy/anonymity as their main use-case. Feature The prefix “crypto” derives from the Greek kruptos or “hidden.” This etymology highlights one of the biggest problems confronting the crypto-currency craze in financial markets today. Speed and anonymity are the greatest assets of the digital tokens. But the former advantage is being eroded by competitors while the latter is becoming a political liability. In the 2020s, governments are growing stronger and more interventionist, not weaker and more laissez faire. Chart 1Loose Money Fuels Crypto Mania Bitcoin and rival crypto-currency Ethereum fell by 29.5% and 43.2% in intra-day trading on May 19, only to finish the day down by 13.8% and 27.2%, respectively. The market panicked on news that China’s central bank had banned firms from handling transactions in crypto-currencies. What really happened was that China’s National Internet Finance Association, China Banking Association, and Payment and Clearing Association issued a statement merely reiterating a 2013 and 2017 policy that already banned firms from handling transactions in crypto-currencies. These three institutions also warned about financial speculation regarding crypto-currencies.1 The crypto market suffered a spike in volatility because it is in the midst of a speculative mania. In the last five years, total market capitalization of crypto-currencies has risen from around $7 billion to $2.3 trillion,2 recording a 34,000% gain. Some crypto-currencies have even recorded returns in excess of that number over a shorter horizon. Price gains have been driven by retail buyers who may or may not know much about this new asset class (Chart 1). Prior to the May 19 selloff, prices had grown overextended and recent concerns over the environment, sustainability, and governance (ESG) had shaken confidence in Bitcoin and its peers. Chinese authorities have already banned financial firms from providing crypto services in a bid to deter ownership of crypto-currencies. And China is not alone. The latest market jitters are a warning sign that government interference in the crypto-currency market is a real threat. Regulation and sovereign-issued digital currencies are starting to enter the fray. While ultra-dovish central bank policies are not changing soon, and therefore crypto-currency price bubbles can continue to grow, crypto-currencies will remain subject to extreme volatility and precipitous crashes. In this report we argue that the fundamental problem with crypto-currencies is that they threaten the economic sovereignty of nation-states. Environmental degradation, financial instability, and black market crime, and other concerns about cryptos have varying degrees of merit. But they provide governments with ample motivation to pursue a much deeper interest in regulating a technological innovation that has the power to undermine state influence over the economy and society. Government scrutiny is a legitimate reason for crypto buyers to turn sellers. Does The World Need Crypto-Currencies? Broadly speaking, there are two primary justifications for crypto-currencies, centered on a transactional basis: speed and privacy/anonymity. The crux of crypto-currency creation rests on these two use cases.3 The speed of crypto-currencies comes from their ability to increase efficiency in local and global payment systems by facilitating financial transactions without the need of a third party (e.g. a financial institution). Cross-border settlement of traditional (fiat) currency transactions processed through the standard SWIFT communications system takes up to two business days. Most transactions involving crypto-currencies over a blockchain network are realized in less than an hour, cross-border or not.4 The fees involved with third-party payments are often more expensive than transacting with crypto-currencies. Simply put, excluding the “middleman” can save money. This is a selling point in a global market that expects to see retail cross-border transactions reach $3.5 trillion by the end of 2021, of which up to 5% are associated with transaction-based fees.5 But this breakthrough in payment system technology can be overstated and is not the main reason for using crypto-currency. Speculation drives current use, especially given that there is speculative behavior even among those who believe that cryptos are safe-haven assets or promising long-term investments (Chart 2). Chart 2Crypto-Currency Use Driven By Speculation Chart 3Consumers Growing Skeptical Of Banking Regulation If a person wants to buy an item from a company in a distant country, that person could use a crypto-currency just as he or she could use a credit card. Both parties would have a secure medium of exchange but, unlike with a credit card, both would avoid using fiat currencies. Neither party could conduct the same transaction using gold or silver. The crucial premise is the existence of an online community of individuals and firms who for one reason or another want to avoid fiat currencies. From a descriptive point of view, the crypto-currency phenomenon implies a lack of trust in modern governments, or at least their monetary systems, and an assertion of individual property rights. The list of crypto-currencies continues to grow. To date, there are approximately 9,800 of them. Some are trying to prove their economic value or use, while others have been created with no intended purpose or problem to solve. Even so, there has yet to be a crypto-currency that overwhelms the use of slower fiat money. In a recent Special Report, BCA Research’s Foreign Exchange Strategist Chester Ntonifor showed that crypto-currencies still have a long way to go to have a chance at replacing fiat monies. While crypto-currencies are showing signs of significant improvement as mediums of exchange, they still fall short as stores of value and units of account. The other primary case for crypto-currencies is privacy or anonymity. The bypassing of intermediaries implies a greater control of funds by the two parties of a transaction. Crypto-currencies are said to be more “private” compared to fiat money. Fiat money is controlled by governments and banks while crypto-currencies have only “owners.” Crypto-currencies are anonymous because they are stored in digital wallets with alphanumeric sequences – there is a limited personal data trail that follows crypto-currency compared to those of electronic fiat currency transactions. In a post-9/11, post-GFC, post-COVID world where a sizable body of consumers is growing more skeptical of government surveillance and regulation and banking industry practices (Chart 3), crypto-currencies give users more than just a means to transact with. However, privacy is not the same as security. Hacking and fraud can affect cryptos as well as other forms of money and attacks will increase with the value of the currencies. Bitcoin At The Helm Of Crypto-Currency Market Chart 4Bitcoin Slows Bitcoin has cemented its status as the number one currency in the crypto-verse.6 It is considered to be the first crypto-currency created, it is the most widely accepted, it is touted as a store of value or “digital gold,” and it is the most featured in quoting alternative crypto-currency pairs across crypto exchanges. As it stands, Bitcoin accounts for around 42% of total crypto-currency market capitalization.7 This share has declined from around 65% at the start of 2021 on the back of the frenzied rise of several alternative coins.8 But rising risks to Bitcoin’s standing will cause the entire crypto-market to retreat. In a Special Report penned in February, BCA Research’s Chief Global Strategist Peter Berezin argued that Bitcoin is more of a trend than a solution and that its usefulness is diminishing. Bitcoin’s transaction speed is slowing and its transaction cost is rising (Chart 4). Slowing speed and rising cost on the Bitcoin network are linked to a scalability problem. The crypto-currency’s network has a limited rate at which it can process transactions related to the fact that records (or “blocks”) in the Bitcoin blockchain are limited in size and frequency. This means that one of its fundamental justifications, transactional speed, will become less attractive over time, should the network not address these issues. Bitcoin also consumes a significant amount of energy, a controversy that is gaining traction in the crypto-currency market after Elon Musk, the “techno-king” of Tesla, cited environmental concerns in reversing his decision to accept Bitcoin payment for his company’s electric vehicles. Energy consumption rises as more coins are mined, since mining each new Bitcoin becomes more computer-power intensive. The need for computing power and energy will continue to increase until all 21 million Bitcoins (total supply) are mined, which is currently estimated to occur by the year 2140. Strikingly, the energy needed to mine Bitcoin over a year are comparable to a small country’s annual power consumption, such as Sweden or Argentina (Chart 5). Chart 5Bitcoin Consumes More Energy Than A Small Country … Bitcoin also generates significant quantities of electronic waste (Chart 6). Chart 6… And Generates A Lot Of Electronic Waste Bitcoin mining is heavily domiciled in China, which accounts for 65% of global mining activity (Figure 1). China’s energy mix is dominated by coal power, which makes up approximately 65% of the country’s total energy mix even after a decade of aggressive state-led efforts to reduce coal reliance. Of this, coal powered energy makes up approximately 60% of Bitcoin’s energy mix in China.9 With several countries aiming to minimize carbon emissions, and with approximately 60% of Bitcoin mining powered by coal-fired energy globally,10 Bitcoin imposes a major negative environmental impact. Figure 1Bitcoin Mining Well Anchored In Asia Bitcoin does not shape up well when compared to gold’s energy intensity either. Bitcoin mining now consumes more energy than gold mining over a single year. While the energy difference is not large, the economic value is. Gold’s energy consumption to economic value trade-off is lower than that of Bitcoin. The production value of gold in 2020 was close to $200 billion, while Bitcoin was measured at less than $25 billion (Chart 7A). On a one-to-one basis, gold even has a lower carbon footprint than Bitcoin (Chart 7B). Chart 7AGold Outshines Bitcoin On Production Value And Carbon Footprint Chart 7BGold Outshines Bitcoin On Production Value And Carbon Footprint Crypto-currency energy consumption and carbon footprint will attract the attention of government regulators. Of course, not all crypto-currencies are heavy polluters. But if the supply of cryptos is constrained by mining difficulties then they will require a lot of energy. If the supply is not constrained then the price will be low. Government Regulation Is Coming Environmental concerns point to the single greatest threat to crypto-currencies – the Leviathan, i.e. the state. In this sense the crypto market’s wild fluctuations on May 19, at the mere whiff of tougher Chinese regulation, are a sign of what is to come. Governments around the world have so far left crypto-currencies largely unregulated but this laissez-faire attitude is already changing. Environmental regulation has already been mentioned. Governments will also be eager to expand their regulatory powers to “protect” consumers, businesses, and banks from extreme volatility in crypto markets. But investors will underrate the regulatory threat if they focus on these issues. At the most basic level, governments around the world will not sit idly by and lose what could become significant control of their monetary systems. The ability to establish and control legal tender is a critical part of economic sovereignty. Governments won control of the printing press over centuries and will not cede that control lightly. If crypto-currencies are adopted widely, then finance ministries and central banks will lose their ability to manipulate the money supply and the general level of prices effectively. Politicians will lose the ability to stimulate the economy or keep inflation in check. Most importantly, while one may view such threats as overblown, it is governments, not other organizations, that will make the critical judgment on whether crypto-currencies threaten their sovereignty. Throughout the world, most crypto-currency exchanges are regulated to prevent money laundering. Crypto-currencies are not legal tender and, aside from Bitcoin, their use is mostly banned in China (Table 1). However, more specialized regulation that targets energy and economic use has yet to be brought into law across the world. Table 1World Governments Will Not Relinquish Hard-Fought Monopolies Over Money Supply In China, initial coin offerings (ICOs – the equivalent of an initial public offering on the stock market) and trading platforms are banned from engaging in exchanges between the yuan and crypto-currencies or tokens. In fact, China recognizes crypto-currencies only as virtual commodities or virtual property. India is another country where exchanges and ICOs are banned. While crypto-currencies are not banned, they are not legal tender. Indian policymakers have recently proposed banning crypto-currencies, however. The proposed legislation is one of the world’s strictest policies against crypto-currencies. It would criminalize possession, issuance, mining, trading, and transferring crypto-assets. If the ban becomes law, India would be the first major economy to make holding crypto-currency illegal. Even China, which has banned mining and trading, does not penalize possession. In the US, Secretary of the Treasury Janet Yellen has already expressed concerns regarding the illicit use of cryptos for supposed criminal gain.11 She is in alignment with European Central Bank President Christine Lagarde. Because of the anonymity of crypto-currencies, identifying users behind illicit transactions is difficult. This means regulators face headwinds in identifying transactions that are made for criminal gain, as compared to fiat transactions. Governments have long dealt with the anonymity of cash but they have ways of monitoring bank accounts and paper bills. Crypto-currencies are beyond their immediate sight of control and therefore will attract growing scrutiny and legislative action in this regard. The Colonial Pipeline ransomware attack on May 7, which temporarily shuttered about 45% of the fuel supply line for the eastern United States, illustrates the point. The DarkSide group of hackers who orchestrated the attack demanded a ransom payment of $4.4 million worth of Bitcoin, which Colonial Pipeline paid them on May 7. Shortly thereafter, unspecified “law enforcement agencies” clawed back the $4.4 million from the hackers’ account (transferring it to an unknown address) and DarkSide lost access to its payment server, DOS servers, and blog. This episode should not be underrated. It was a successful, large-scale cyber-attack on critical infrastructure in the world’s most powerful country. It highlighted the illicit uses to which crypto-currencies can be put. True, criminals demand ransoms in fiat money as well – and many crypto-currency operators will distance themselves from the criminal underworld. Nevertheless governments will give little slack to an emerging technology that presents big new law enforcement challenges and is not widely used by the general public. Ultimately governments will pursue their sovereign interests in controlling money, the economy, and trade, listening to their banking lobby, expanding their remit to “protect” consumers, and cracking down on illicit activity. Governments are not capable of abolishing crypto-currencies altogether, or the underlying technology of blockchain. But they will play a large and growing role in regulating them. Central Banks Advancing On Digital Currencies Central bank digital currencies (CBDCs) will leave crypto-currencies in the realm of speculative assets. CBDCs are a form of digital money denominated in a country’s national unit of account and represent a liability on a central bank’s balance sheet. This is different from current e-money that represents a claim on a private financial institution’s balance sheet. It is also different from crypto-currencies, because there is a central authority behind a CBDC, unlike with crypto-currencies due to their decentralized nature. In China, the People’s Bank of China (PBoC) has suggested its rollout of a digital yuan is “ready” despite no release to date. Beta testing is ongoing in several provinces. The PBoC’s justification for a digital yuan comes from China’s growing cashless economy. The transition away from cash is largely thanks to mobile payment platforms like Alibaba’s Alipay and Tencent’s WeChat Pay, which, between the two of them, control almost the entire mobile payments market of some 850 million users. There is a significant amount of systemic risk in this system – one reason why Chinese authorities have recently subjected these companies to new scrutiny and regulation. Should Alibaba or Tencent go bankrupt, the local payment system will crash. The PBoC’s efforts will increase competition in the local payments space and reduce this systemic risk. Policymakers are also concerned that as Chinese citizens choose to hold their money in digital wallets provided by Alibaba and Tencent instead of bank accounts, liquidity is being drained from the traditional banking system, putting deposit levels at banks under strain, and posing risks to liability matching. The digital yuan will still involve a third party, unlike crypto-currencies which do not. Doing away with commercial banks is not a reality – indeed the Chinese Communist Party seeks to buttress the state-owned commercial banks in order to maintain control of the economy. What the digital yuan does, and other CBDCs will do too, is utilize blockchain technology, which is faster and more secure than traditional payment networks. In the US, the Fed has been studying the viability of a CBDC US dollar. The Fed has stated that it is carefully exploring whether a CBDC will lead to “safer, less expensive, faster, or otherwise more efficient payments.” While the Fed has yet to find a single standout case for a CBDC US Dollar, Fed Chair Jerome Powell said last year that the US has a “competitive payments market” with “fast and cheap services, particularly in comparison to other nations exploring a CBDC.” To date, the Fed’s observation is that many of the challenges that CBDCs hope to address do not apply to the US, including disuse of physical cash, narrow reach or high concentration of banking, and weak infrastructure for payment systems. Rather, the Fed is more focused on developing the FedNow real-time payment system for private banks. This is much the same as in Europe, where physical cash still plays a major role in day-to-day economic activity and where local payment systems are fast and secure. But central banks around the world continue to engage in work centered around CBDCs (Charts 8A and 8B) – and China’s progress will encourage others to move faster. Advanced economies are mostly interested in creating a safer and more efficient payment system, while emerging and developed economies have interest across several areas such as financial stability, monetary policy setting, and inclusiveness of banking, as well as efficiency and safety (Chart 9). CBDCs are especially attractive to emerging market policy makers at targeting those who lack access to traditional banking. Chart 8ACentral Banks Advancing On CBDC Work Chart 8BCentral Banks Advancing On CBDC Work Chart 9Central Banks CBDC Interest Areas In remote areas, access to banking is scarce and expensive. CBDCs can help solve this problem. Individuals would have CBDC accounts directly on a central bank ledger. They could then access their money and transact through a digital wallet application that is linked to the CBDC account. Giving people access to digital currency would allow them to transact quickly, in remote settings, without the need of hard currency. Monetary policy transmission is also better in advanced economies. In emerging markets, there are bottlenecks in local financial markets. Looser central monetary policy does not always translate into cheaper financing across the economy. In remote and poverty stricken areas, monetary policy transmission is sticky, meaning high costs of borrowing can persist even through accommodative policy cycles. This is a smaller issue in advanced economies. Payment systems in advanced economies are due an overhaul in security and efficiency, and CBDCs and blockchain technology will provide this. CBDCs will prove to be just as efficient to transact with as any crypto-currencies available today. CBDCs will also be legal tender and accepted by all vendors. The anonymity factor will be lost but this will not be a problem for most users (whereas legal issues will become a problem for crypto-currencies). The probability of central banks issuing CBDCs in both the short and medium term, both in the retail and wholesale space, is rising. If advanced economies like those of the G7 issue CBDCs soon, policy makers will undoubtedly ensure the use of it over the currently circulating and partially accepted crypto-currencies. The endgame will leave crypto-currencies in the highly speculative asset class, perhaps even in the black market where anonymity is valued for transactions that wish not to be tracked. Investment Takeaways Prices of crypto-currencies may continue to rise given sky-high fiat money creation amid the COVID pandemic and ultra-low interest rates. Digitalization is the natural next step in the evolution of money from precious metals to paper banknotes to electronic coin. But the market leader, Bitcoin, is encountering more headwinds. The primary case for the use of Bitcoin is challenged due to slowing transaction speeds and rising transaction costs. The virtual currency is primarily mined using coal-powered energy, resulting in growing scrutiny from governments and consumers. Government regulation is entering the ring and policymakers will take an increasingly heavy-handed role in trying to ensure that cryptos do not undermine economic sovereignty, financial stability, and law and order. When central banks begin to rollout digital currencies, especially those domiciled in advanced economies, crypto-currencies as medium of exchange will lose much of their allure. Crypto-currencies will remain as anti-fiat currencies and speculative assets. Risks To The View Given the controversy surrounding crypto-currencies, it is only fair to state outright the risks to our view. We would also recommend clients read our colleague Dhaval Joshi’s latest bullish take on Bitcoin. First, scaling up Bitcoin’s network and processing transactions in batches instead of single transactions will resolve transaction time and cost risks, restoring efficiency. This is a clear solution to efficiency concerns. However, scaling and batching transactions are not on the immediate horizon of Bitcoin developers. Bitcoin’s network will still need to undergo another “halving” in order for this risk to subside and for the network to scale. A halving of the network will only occur again in 2024.12 Second, on the environment: Bitcoin mining is not solely dependent on fossil fuel energy that gives it a “dirty” footprint. Renewables already make up some 25% of Bitcoin mining. Increasing the use of renewables in Bitcoin’s energy mix will help lower its environmental impact. However, this is easier said than done. Global renewable energy has yet to scale up to a point where it can consistently out-supply existing fossil-fuel energy. Mining hardware also has its associated carbon footprint that would need to be addressed. And location matters too. Crypto-currency mining farms are large-scale projects. Simply uprooting operations to a country that could lower the carbon footprint of a mining farm or two is not viable due to the costs involved. Hence crypto-currency mining will probably continue to be a “dirty” operation but a rapid shift to renewables would challenge our thesis. Bitcoin’s network is also based off a “proof of work” protocol. Miners must prove that a certain amount of computational effort has been expended for confirming blocks on the network, allowing transactions to be processed. Proof of work is energy intensive. Other crypto-currencies, like Ethereum, will adopt a “proof of stake” protocol. Simply put, transactions are confirmed by users and their stake in the associated crypto-currency. Proof of stake is less energy intensive compared to proof of work. Third, as to government regulation, the longer policymakers take to enact legislation targeting crypto-currencies, the larger their market will grow. Regulation in China and India may set a benchmark for major economies but not all will follow in the Asian giants’ footsteps. Some governments have been slow to study crypto-currencies, meaning legislation aimed at governing or regulating them may still be long in coming. Innovation is a good thing and free economies will not wish to restrain crypto-currencies or blockchain technology unduly, for fear of missing out. Fourth, on CBDCs, some central banks may only adopt them based on their respective economic needs. However, rising crypto-currency populism drives associated economic risks which can force the hands of central banks to adopt CBDCs in lieu of said needs. Each country faces unique challenges. Some central banks may not want to be left behind even if they believe their policy framework is facilitating economic activity efficiently. While the Fed has stated that it will not adopt a CBDC for the primary reason of ensuring payment security since it believes it already has a safe system in place, this view will change. The Fed could justify a move to a CBDC US dollar on the single basis of transitioning to a more sophisticated technology for the future. The Fed will not want to be caught behind the curve considering the PBoC is priming its digital yuan for release soon. Technological leadership is a strategic imperative of the United States and that imperative applies to financial technology as well as other areas.   Guy Russell Research Analyst GuyR@bcaresearch.com Matt Gertken Vice President Geopolitical Strategy mattg@bcaresearch.com Footnotes 1 Muyao Shen, “China Reiterates Crypto Bans From 2013 and 2017”, coindesk, May 18, 2021, coindesk.com. 2 As of May 11, 2021. 3 There are several other reasons or “problems” that crypto-currencies are created for or to solve, but speed and privacy form the basis of crypto-currencies first coming into existence. 4 Not all crypto-currencies transact in less than an hour.

Highlights The drubbing that cryptocurrencies have received over the past two weeks is just a taste of things to come. Crypto markets will continue to face tighter regulation, as this week’s announcements from China and the US Treasury underscore. The hope that cryptocurrencies can ever truly “go green” is wishful thinking. Given their decentralized nature, cryptocurrencies require real resources to be expended to permit secure transactions to take place. In addition to their technical limitations, cryptocurrencies face a fundamental constraint, which we dub the “Crypto Impossibility Theorem.” The Crypto Impossibility Theorem states that cryptocurrencies will be viable only if they offer a higher return than equities. The assumption that cryptos can generate a return in excess of equities is almost certain to be false since it would require that cryptocurrency holdings rise more quickly than income in perpetuity. In the near term, the pain in crypto markets could drag down other speculative assets such as tech stocks. In the long term, diminished investor interest in cryptos will benefit the stock market, as investor attention focuses back on equities. Cryptos: Can’t Have It All Investors who track the cryptocurrency market might be aware of the “blockchain trilemma.” It posits that cryptocurrencies can possess only two of the following three attributes: decentralization, security, and scalability. Bitcoin is both highly decentralized and reasonably secure. However, because control of the Bitcoin blockchain is distributed across thousands of individual computer nodes, it is also very slow. The Bitcoin network can barely process five transactions per second, compared to over 20,000 for the Visa network (Chart 1). The average fee for a Bitcoin transaction is around $30, a number that has risen over the past few years (Chart 2). Chart 1Speed Of Transactions, Or Lack Thereof Chart 2Rising Cost Per Transaction   The elaborate puzzles that the Bitcoin algorithm must solve to verify transactions are extremely energy intensive. Bitcoin mining consumes more energy than entire countries such as Sweden, Argentina, and Pakistan (Chart 3). About two-thirds of Bitcoin mining currently takes place in China, often using electricity generated by burning coal. Chart 3Bitcoin And Ethereum: How Dare You! Some claim that Bitcoin and other cryptocurrencies are shifting to renewable energy sources, a trend that will continue in the years ahead. However, this argument misses the point, which is that the “proof of work” mechanism that underpins Bitcoin requires that real resources be expended. Suppose that all Bitcoin mining could be performed entirely for free using solar energy. This would reduce the cost of running a “mining rig,” incentivizing more mining. The Bitcoin algorithm operates in such a way that the difficulty of mining coins increases as the total computational power of all miners grows. In this computational rat race, miners would need to purchase more servers with ever more powerful specifications to keep up with their competitors. And semiconductors do not grow on trees. It takes real resources to produce them. As this recent Bloomberg article pointed out, Taiwan Semiconductor generates almost 50% more greenhouse emissions than General Motors. Like Bitcoin, Ethereum uses the “proof of work” mechanism to verify transactions. There have been active discussions to shift Ethereum to a “proof of stake” mechanism, which would greatly expedite transactions.1 However, some have argued that a proof of stake system would degrade security, allowing for “double-spend attacks” where someone transfers coins to someone else but then spends the coins before the transaction is completed. The Crypto Impossibility Theorem We will not delve any further into the technical nature of the blockchain trilemma other than to note that it poses a serious challenge to the entire cryptocurrency project. Instead, let us highlight another obstacle that has received less attention – one that could be even more damaging for the prospects of cryptocurrencies in the long run. Let us hyperbolically call it the “Crypto Impossibility Theorem.” The Crypto Impossibility Theorem states that a cryptocurrency will be viable only if it offers a higher return than equities. As we discuss below, the assumption that cryptos can generate a return in excess of equities is almost certain to be false since it would require that cryptocurrency holdings rise more quickly than income in perpetuity. This implies that the value that investors currently attach to cryptos will turn out to be illusory. To see the theorem in action, recall that money serves three functions: As a unit of account, as a medium of exchange, and as a store of value. It is doubtful that anyone seriously thinks that the price tag on a box of cereal will ever be displayed in units of Bitcoin, ether, or any of the various dog coins currently in vogue. Thus, we can scratch “unit of account” off the list of possible crypto uses. What about medium of exchange? One can imagine a scenario where the prices of goods and services are still listed in dollars, but one may transfer the equivalent in cryptocurrencies to purchase them. However, this raises an obvious question: Why would anyone choose to hold a cryptocurrency if wages and prices are denominated in fiat currencies such as US dollars or euros? The only possible answer is that people must see cryptocurrencies as fulfilling the third function of money, namely being a store of value. Would people be willing to hold cryptocurrencies if their prices generally moved sideways? It is doubtful. Cryptocurrencies are risky. Cryptocurrency accounts are not subject to deposit insurance. Crypto prices are also extremely volatile. During the pandemic, the S&P 500 fell by 34%, but the price of Bitcoin sank by an even greater 53%. Other cryptocurrencies fared even worse. In contrast, the trade-weighted US dollar strengthened by about 4% while gold prices only fell marginally (Chart 4). Thus, to incentivize people to hold cryptos, the prospective capital gain has to be large enough to offset the inherent volatility in owning these currencies. Chart 4Cryptocurrencies Fared Badly During Last Year’s Equity Sell-Off This is where the Crypto Impossibility Theorem comes in. Unlike dividend-paying stocks, cryptocurrencies do not provide any income to their holders. Thus, even if cryptos were just as risky as stocks, the price of cryptos would still need to rise more than the price of stocks in order to ensure that investors remain indifferent between the two asset classes. In practice, as the experience of the pandemic demonstrates, cryptos are even riskier than stocks. Thus, the expected return on cryptos has to exceed the expected increase in stock prices by more than the dividend yield. The problem for crypto holders is that this is not mathematically possible. Even if one controls for the rise in price-earnings multiples over time, equity returns have generally exceeded nominal GDP growth (Table 1). Hence, if cryptos need to offer superior returns to equities, and if the return on equities is at least equal to nominal GDP growth, then the market capitalization of cryptocurrencies will not only end up rising faster than for stocks, it will rise faster than aggregate national income. In a digital world where people need ever-less money to facilitate transactions, there is no good reason to expect this to happen. Table 1Equity Returns And GDP Growth A Fashion Choice Crypto-optimists might argue that the required rate of return to holding cryptos will decline as the market matures. This is wishful thinking. Equities derive their value from the fundamentals of a company’s business. In contrast, cryptocurrencies have no intrinsic value. Their value is whatever others are willing to pay for them. Not only does this make cryptocurrencies inherently more risky than equities, it also makes them highly susceptible to fashion trends. It is not surprising that many upstart cryptocurrencies have crafted ties with celebrities and other “influencers.” The whole point is to get enough people interested in a cryptocurrency to generate a feedback loop of wider adoption, thus allowing the currency’s early backers to cash out. The drubbing that cryptocurrencies have received over the past two weeks is just a taste of things to come. In this sense, cryptocurrencies are even more vulnerable to affinity scams than other assets such as precious metals. While apocalyptic warnings of “currency debasement” have long been used to sell bullion, at least with gold and silver, you truly do get something that is in short supply. In the case of cryptocurrencies, while the supply of any individual cryptocurrency may be limited, the overall supply is unbounded. This means that the average price of each currency is likely to rise much less than the aggregate value of all cryptocurrencies, making the entire asset class even less viable over time.   Cryptogeddon The drubbing that cryptocurrencies have received over the past two weeks is just a taste of things to come. As Matt Gertken and Guy Russell discuss in this week’s Geopolitical Strategy report, crypto markets will continue to face tighter regulation (Table 2). Just this week, China reiterated its ban on financial companies offering cryptocurrency services. As part of its broader effort to crack down on tax evasion, the US Treasury Department also announced that it will require any cryptocurrency transfer worth $10,000 or more to be reported to the IRS. Table 2Regulation Of Cryptos: What Can And Cannot Be Done The blockchain trilemma will make it impossible for cryptos to overcome ESG concerns, while the Crypto Impossibility Theorem will prevent cryptocurrencies from ever being stable stores of value. In the meantime, an ebbing of input price inflation will take some of the wind out of the sails from the argument that cryptos are an indispensable hedge against the “inevitable” debasement of fiat monies. Chart 5 shows that DRAM prices have rolled over. Lumber prices have dropped 11% so far this week. Corn, soybean, and steel prices have also backed off their highs. Cryptos are like sharks; they need to move forward or they will sink. Back when they were unknown to most investors, a speculative case could have been made for buying cryptos. However, that case vanished earlier this year when the aggregate value of cryptocurrencies briefly surpassed the entire stock of US dollars in circulation (Chart 6). Even with the recent correction, there are 17 cryptocurrencies with market capitalizations above $10 billion (Table 3). Chart 5To The Moon And Back? Chart 6Aggregate Value Of Cryptos Briefly Surpassed The Entire Stock Of US Dollars In Circulation Table 3Close To 20 Cryptos Have A Market Cap In Excess Of US$10bn What will the ongoing crypto collapse mean for the broader investment landscape? In the near term, the pain in crypto markets could drag down other speculative assets such as tech stocks. In the long term, diminished investor interest in cryptos will benefit the stock market, as investor attention focuses back on equities. For the broader economy, the impact of a crypto bear market will be limited. The banking system has very little exposure to cryptos. There will be a modest adverse wealth effect from falling crypto prices. However, the inability of a few laser-eyed crypto traders to buy their Lambos is hardly going to matter much against the backdrop of strong stimulus-fueled consumption growth in the US and a number of other economies. Investors should continue to overweight stocks in a global asset portfolio, favoring value over growth, cyclicals over defensives, and non-US stocks over their US peers.

Highlights Global oil markets will remain balanced this year with OPEC 2.0's production-management strategy geared toward maintaining the level of supply just below demand.  This will keep inventories on a downward trajectory, despite short-term upticks due to COVID-19-induced demand hits in EM economies and marginal supply additions from Iran and Libya over the near term. Our 2021 oil demand growth is lower – ~ 5.3mm b/d y/y, down ~ 800k from last month's estimate – given persistent weakness in realized consumption.  We have lifted our demand expectation for 2022 and 2023, however, expecting wider global vaccine distribution and increased travel toward year-end. The next few months are critical for OPEC 2.0: The trajectory for EM demand recovery will remain uncertain until vaccines are more widely distributed, and supply from Iran and Libya likely will increase this year.  This will lead to a slight bump in inventories this year, incentivizing KSA and Russia to maintain the status quo on the supply side. We are raising our 2021 Brent forecast back to $63/bbl from $60/bbl, and lifting our 2022 and 2023 forecasts to $75 and $78/bbl, respectively, given our expectation for a wider global recovery (Chart of the Week). Feature A number of evolving fundamental factors on both sides of the oil market – i.e., lingering uncertainty over the return of Iranian and Libyan exports and the strength of the global demand recovery – will test what we believe to be OPEC 2.0's production-management strategy in the next few months. Briefly, our maintained hypothesis views OPEC 2.0 as the dominant supplier in the global oil market. This is due to the low-cost production of its core members (i.e., those states able to attract capital and grow production), and its overwhelming advantage in spare capacity, which we reckon will average in excess of 7mm b/d this year, owing to the massive production cuts undertaken to drain inventories during the COVID-19 pandemic. Formidable storage assets globally – positioned in or near refining centers – and well-developed transportation infrastructures also support this position. We estimate core OPEC 2.0 production will average 26.58mm b/d this year and 29.43mm b/d in 2022 (Chart 2). Chart of the WeekBrent Prices Likely Correct Then Move Higher in 2022-23 Chart 2OPEC 2.0 Will Maintain Status Quo The putative leaders of the OPEC 2.0 coalition – the Kingdom of Saudi Arabia (KSA) and Russia – have distinctly different goals. KSA's preference is for higher prices – ~ $70-$75/bbl (basis Brent) to the end of 2022. Higher prices are needed to fund the Kingdom's diversification away from oil. Russia's goal is to keep prices closer to the marginal cost of the US shale-oil producers, who we characterize as the exemplar of the price-taking cohort outside OPEC 2.0, which produces whatever the market allows. This range is ~ $50-$55/bbl. The sweet spot that accommodates these divergent goals is on either side of $65/bbl for this year. OPEC 2.0 June 1 Meeting Will Maintain Status Quo With Brent trading close to $70/bbl, discussions in the run-up to OPEC 2.0's June 1 meeting likely are focused on the necessity to increase the 2.1mm b/d being returned to the market over the May-July period. At present, we do not believe this will be necessary: Iran likely will be returning to the market beginning in 3Q21, and will top up its production from ~ 2.4mm b/d in April to ~ 3.85mm b/d by year-end, in our estimation. Any volumes returned to the market by core OPEC 2.0 in excess of what's already been agreed going into the June 1 meeting likely will come out of storage on an as-needed basis. Libya will likely lift its current production of ~ 1.3mm b/d close to 1.5mm b/d by year end as well. We are expecting the price-taking cohort ex-OPEC 2.0 to increase production from 53.78mm b/d in April to 53.86mm b/d in December, led by a 860k b/d increase in US output, which will take average Lower 48 output in the US (ex-GOM) to 9.15mm b/d by the end of this year (Chart 3). When we model shale output, our expectation is driven by the level of prompt WTI prices and the shape of the forward curve. The backwardation in the WTI forward curve will limit hedged revenues at the margin, which will limit the volume growth of the marginal producer. We expect global production to slowly increase next year, and the year after that, with supply averaging 101.07mm b/d in 2022 and 103mm b/d in 2023.  Chart 3US Crude Output Recovers, Then Tapers in 2023 Demand Should Lift, But Uncertainties Persist We expect the slowdown in realized DM demand to reverse in 2H21, and for oil demand to continue to recover in 2H21 as the US and EU re-open and travel picks up. This can be seen in our expectation for DM demand, which we proxy with OECD oil consumption (Chart 4). EM demand – proxied by non-OECD oil consumption – is expected to revive over 2022-23 as vaccine distribution globally picks up. As a result, demand growth shifts to EM, while DM levels off. China's refinery throughput in April came within 100k b/d of the record 14.2mm b/d posted in November 2020 (Chart 5). The marginal draw in April stockpiles could also signify that as crude prices have risen higher, the world’s largest oil importer may have hit the brakes on bringing oil in. In the chart, oil stored or drawn is calculated as the difference between what is imported and produced with what is processed in refineries. With refinery maintenance in high gear until the end of this month, we expect product-stock draws to remain strong on the back of domestic and export demand. This will draw inventories while maintenance continues. Chart 4EM Demand Will Recovery Accelerates in 2022-23 Chart 8China Refinery Runs Remain Strong COVID-19-induced demand destruction remains a persistent risk, particularly in India, Brazil and Japan. This is visible in the continued shortfall in realized demand vs our expectation so far this year. We lowered our 2021 oil demand growth estimate to ~ 5.3mm b/d y/y, which is down ~ 800k from last month's estimate, given persistent weakness in realized consumption. Our demand forecast for 2022 and 2023 is higher, however, based on our expectation for stronger GDP growth in EM economies, following the DM's outperformance this year, on the back of wider global vaccine distribution year-end (Table 1). Table 1BCA Global Oil Supply - Demand Balances (MMb/d, Base Case Balances) Our supply-demand estimates continue to point to a balanced market this year and into 2022-23 (Chart 6). Given our expectation OPEC 2.0's production-management strategy will remain effective, we expect inventories to continue to draw (Chart 7). Chart 6Markets Remained Balanced Chart 7Inventories Continue To Draw CAPEX Cuts Bite In 2023 In 2023, we are expecting Brent to end the year closer to $80/bbl than not, which will put prices outside the current range we believe OPEC 2.0 is managing its production around (Chart 8). We have noted in the past continued weakness in capex over the 2015-2022 period threatens to leave the global market exposed to higher prices (Chart 9). Over time, a reluctance to invest in oil and gas exploration and production prices in 2024 and beyond could begin to take off as demand – which does not have to grow more than 1% p.a. – continues to expand and supply remains flat or declines. Chart 8By 2023 Brent Trades to /bbl Chart 9Low Capex Likely Results In Higher Prices After 2023 Bottom Line: We are raising our 2021 forecast back to an average of $63/bbl, and our forecasts for 2022 and 2023 to $75 and $78/bbl. We expect DM demand to lead the recovery this year, and for EM to take over next year, and resume its role as the growth engine for oil demand. Longer term, parsimonious capex allocations likely result in tighter supply meeting slowly growing demand. At present, markets appear to be placing a large bet on the buildout of renewable electricity generation and electric vehicles (EVs). If this does not occur along the trajectory of rapid expansion apparently being priced by markets – i.e., the demand for oil continues to expand, however slowly – oil prices likely would push through $80/bbl in 2024 and beyond.   Robert P. Ryan Chief Commodity & Energy Strategist rryan@bcaresearch.com Ashwin Shyam Research Associate Commodity & Energy Strategy ashwin.shyam@bcaresearch.com   Commodities Round-Up Energy: Bullish The Colonial Pipeline outage pushed average retail gasoline prices in the US to $3.03/gal earlier this week, according to the EIA. This was the highest level for regular-grade gasoline in the US since 27 October 2014. According to reuters.com, the cyberattack that shut down the 5,500-mile pipeline was the most disruptive on record, shutting down thousands of retail service stations in the US southeast. Millions of barrels of refined products – gasoline, diesel and jet fuel – were unable to flow between the US Gulf and the NY Harbor because of the attack, which was launched 7 May 2021 (Chart 10). While most of the system is up and running, problems with the pipeline's scheduling system earlier this week prevented a return to full operation. Base Metals: Bullish Spot copper prices remained on either side of $4.55/lb (~ $10,000/MT) by mid-week following a dip from the $4.80/lb level (Chart 11). We remain bullish copper, particularly as political risk in Chile rises going into a constitutional convention. According to press reports, the country's constitution will be re-written, a process that likely will pave the way for higher taxes and royalties on copper producers.1 In addition, unions in BHP mines rejected a proposed labor agreement, with close to 100% of members voting to strike. In Peru, a socialist presidential candidate is campaigning on a platform to raise taxes and royalties. Precious Metals: Bullish According to the World Platinum Investment Council, platinum is expected to run a deficit for the third consecutive year in 2021, which will amount to 158k oz, on the back of strong demand. Refined production is projected to increase this year, with South Africa driving this growth as mines return to full operational capacity after COVID-19 related shutdowns. Automotive demand is leading the charge in higher metal consumption, as car makers switch out more expensive palladium for platinum to make autocatalysts in internal-combustion vehicles. Ags/Softs: Neutral Corn prices continued to be better-offered following last week's WASDE report, which contained the department's first look at the 2021-22 crop year. Corn production is expected to be up close to 6% over the 2020-21 crop year, at just under 15 billion bushels. On the week, corn prices are down ~ 15.3%.

Neutral Home improvement retailers (HIR) were among the lucky ones that were allowed to keep their doors open during the pandemic. As a result, these big box retailers benefitted from the lockdown as people used their stimulus checks and newly available free time, thanks to the work from home trend, to remodel their homes. Now that other retailers are opening their doors, the allure of being outright bullish the S&P HIR index has diminished (bottom panel). Add to this the fact that a great deal of future demand was pulled forward for HIR stores, and there is likely little upside left in the S&P HIR index. In addition, rates are moving higher at the margin, and energy costs are also breaking out. Taken together they form our consumer drag indicator and the implication is that the path of least resistance is lower for relative profit growth estimates (middle panel).  While the sector faces some headwinds, we remain neutral this consumer discretionary sub-industry and are not ready just yet to downgrade exposure. One offsetting factor is soaring lumber prices that are buttressing profits given that HIR make a set margin on lumber-related sales (not shown). Bottom Line: Stay neutral the S&P home improvement retail index, but stay tuned. The ticker symbols for the stocks in this index are: BLBG: S5HOMI – HD, LOW. ​​​​​​​

Underweight High-Conviction While our underweight homebuilders call has been offside of late, we are sticking with it given the recent turn in some crucial data series. Interest and mortgage rates are a key determinant for the industry’s relative performance, and given the sell-off in the bond market, it is only a question of when, not if, US building permits will play catch up to the downside (mortgage rates shown inverted, middle panel). If rising mortgage rates (although from a low base) is not enough to cool down the US housing market, then an astronomical rise in lumber prices will likely weigh on it soon. As a reminder, framing lumber accounts for 15-20% of the total cost of building a home (bottom panel). Before long, this input cost inflation will eat into homebuilders’ margins and thus cut into profits. Bottom Line: We reiterate our cyclical and high-conviction underweight stance in the S&P homebuilding index. The ticker symbols for the stocks in this index are: BLBG: S5HOME – LEN, PHM, DHI, NVR.
