Ruchir Sharma, chief global strategist and head of emerging markets at Morgan Stanley Investment Management, argued in a Financial Times opinion piece that Bitcoin is making meaningful progress toward challenging the U.S. dollar’s long-held dominance in the global monetary system. His central warning to governments was straightforward: they should no longer assume that traditional state-issued currencies will remain the only trusted stores of value or mediums of exchange.
The Dollar’s Long Reign Faces a New Kind of Challenger
Sharma framed his argument in historical terms. The U.S. dollar has served as the world’s reserve currency for roughly 100 years, while past reserve currencies lasted an average of about 94 years. That alone, he suggested, should invite questions about how much longer the dollar can maintain its position. For years, however, the lack of a credible successor helped preserve the greenback’s supremacy. Alternatives such as the euro and China’s renminbi have not fully met the requirements needed to displace it.
According to Sharma, the pandemic era exposed both the power and the vulnerability of the dollar-based system. U.S. policymakers were confident they could expand the money supply aggressively and run massive deficits without immediately threatening the dollar’s reserve status. But in his view, a new class of contenders has now emerged: cryptocurrencies, especially Bitcoin. Unlike traditional rivals, Bitcoin is being promoted by supporters as a decentralized and politically neutral alternative to government-controlled money.
Why Bitcoin Benefited From the Pandemic-Era Monetary Response
Sharma acknowledged that Bitcoin still has many critics and that some investors continue to prefer gold as a hedge against currency debasement. Even so, he noted that many market participants bought Bitcoin heavily out of fear that central banks—led by the U.S. Federal Reserve—were eroding the value of fiat currencies through aggressive monetary expansion. That concern, he said, helped drive a major rally in the asset.
In the article, Sharma pointed out that Bitcoin had more than quadrupled since March, making it one of the standout investments of 2020. For him, this was not merely a speculative episode in isolation. It reflected a broader erosion of trust in conventional monetary arrangements at a time when governments were printing unprecedented amounts of money in response to the Covid-19 shock.
He linked that concern to the United States’ external liabilities. After years of accumulation, U.S. debts to the rest of the world had surpassed 50% of economic output the previous year, a level he said the International Monetary Fund often associates with mounting crisis risk. During the lockdown period, with Washington continuing to borrow heavily, that ratio reportedly jumped further to 67%. Sharma argued that reserve currencies tend to decline when the rest of the world starts to lose confidence in the issuing country’s ability to keep paying its bills. In his reading, that historical pattern could eventually threaten the dollar as well.
From Store of Value to Medium of Exchange
A key part of Sharma’s thesis was that Bitcoin is no longer only a speculative asset or digital store of value. He suggested it is also beginning to make progress as a medium of exchange. While most bitcoins are still held primarily for investment purposes, he argued that real-world transactional use is slowly increasing.
He cited examples of small businesses using Bitcoin in international trade, particularly in places where access to dollars is limited or domestic currencies are unstable. Countries such as Nigeria, where dollars can be difficult to obtain, and Argentina, where local currency instability has long been a concern, illustrate the practical appeal of a borderless digital asset. In those environments, Bitcoin may serve not only as a speculative instrument, but also as a functional tool for settlement and preserving value.
Sharma also pointed to moves by major fintech platforms as evidence of growing mainstream acceptance. He noted that PayPal and its subsidiary Venmo planned to allow 28 million merchants to accept Bitcoin, a development that could significantly broaden exposure to cryptocurrency payments. For proponents of Bitcoin, such steps represent an important bridge between digital assets and everyday commercial activity.
A Warning to Governments and Central Banks
Even with this constructive outlook, Sharma did not present Bitcoin as a risk-free inevitability. He explicitly warned that the cryptocurrency’s surge could still prove to be a bubble. However, he argued that even if that bubble were to burst, the rush into cryptocurrencies during the year should still be taken seriously by governments—particularly by those relying on aggressive money creation.
His message was less about making a precise prediction of Bitcoin replacing the dollar overnight, and more about identifying a structural shift in public attitudes toward money. People, especially those comfortable with technology, are increasingly willing to experiment with alternatives outside the traditional banking and sovereign currency framework. Once trust in official money weakens, digital substitutes can gain momentum quickly, even if they remain volatile.
That dynamic, in Sharma’s view, should concern policymakers. If governments assume citizens and businesses will always rely on traditional currencies simply because they have historically done so, they may underestimate how rapidly adoption patterns can change. The search for alternatives is likely to continue as long as inflation fears, currency instability, and distrust of central bank policy remain part of the global conversation.
Could Regulation Speed Up the Shift?
Sharma ended on a provocative note, suggesting that attempts by governments to clamp down on the digital currency boom could actually backfire. Rather than restoring confidence in the existing system, aggressive regulation might reinforce the perception that authorities feel threatened by monetary competition. In that sense, intervention could accelerate what he described as a broader populist backlash against traditional money.
His thesis ultimately rests on a combination of macroeconomics and behavioral change. Bitcoin’s rise, in his telling, is not just about price appreciation. It is also about the gradual emergence of an asset that appeals to those seeking insulation from sovereign debt expansion, fiat dilution, and payment frictions in the global economy. Whether Bitcoin ever fully replaces the dollar as the world’s reserve currency remains uncertain, but Sharma’s argument is that it is no longer possible to dismiss the idea as irrelevant.
For investors, policymakers, and financial institutions, the significance of that argument lies in what it says about confidence. Reserve currency status is not sustained by tradition alone; it depends on deep and continuing trust in the underlying political and economic system. If that trust erodes, even slowly, capital will seek alternatives. Sharma believes Bitcoin is increasingly positioned to benefit from exactly that kind of shift.
