Stablecoins as an Accelerant: Why the Next Currency Crisis Could Be Harder to Control

To be honest, this thought sometimes keeps me up at night: the next global currency crisis could become even more unpredictable due to stablecoins than anything we’ve experienced so far. And this isn’t science fiction—it’s a serious warning now being highlighted by the Federal Reserve Bank of New York in a brand-new study. The researchers didn’t just engage in theoretical debates; they worked with real data—4.5 million observations, to be precise. The result? Stablecoins could completely upend the rules of engagement in the next financial crisis.
Why stablecoins act like a catalyst
Stablecoins such as Tether, USD Coin, or DAI have evolved from a niche idea to a multi-billion-dollar market in recent years. With over $160 billion in market capitalization in 2024—more than the GDP of some small countries—they’re no longer just for tech enthusiasts or crypto devotees. In countries where local currencies are eroding like sand through fingers, they’re increasingly being used as a lifeline.
Now, for the first time, the New York Fed study empirically demonstrates how dangerous this phenomenon could be during a real crisis. The researchers focused specifically on wallets linked to ENS tags (crypto address books)—accounts presumably used by investors trading in stablecoins. What did they find? During crisis weeks, massive amounts of capital flee traditional monetary systems into these digital dollar substitutes. The situation becomes especially dire when a country’s local currency comes under pressure. Suddenly, investors rush to stablecoins—and at a pace no central bank in the world can curb.
“Stablecoins act as a safe haven during a crisis, much like the U.S. dollar,” says one of the study’s authors. “But while central banks can’t just shut down the dollar, funds vanish into stablecoins through the cracks in the global financial architecture—and at a speed that’s almost impossible to control.”
When controls start looking like Swiss cheese
The real problem: stablecoins systematically undermine capital controls, which many countries rely on to stabilize their economies during crises. Imagine living in a country where your currency loses value every single day. The government scrambles to slow capital flight—but suddenly, investors can simply buy stablecoins and spirit their money beyond the reach of local authorities.
The study ran the numbers: even moderate adoption of stablecoins could r



educe the effectiveness of capital controls by up to 30 percent. Countries with high inflation or steep currency devaluations are hit hardest. For their citizens, stablecoins offer a fast, easy, and often cheap alternative—but for central banks, they’re a nightmare, as monetary policy and money supply slip from their grasp.
The ticking time bomb in the global financial system
But the issue isn’t confined to individual countries or regions. The New York Fed also warns of systemic risks to the entire financial system. While stablecoins are pegged to traditional assets like the U.S. dollar, who guarantees those reserves actually exist? Transparency is often lacking, and when push comes to shove, these supposedly “stable” currencies may prove anything but secure.
“Stablecoins spread the illusion of stability,” says an independent crypto expert not involved in the study. “Investors believe their money is safely parked while simultaneously taking risky bets in the real economy. Until the whole house of cards collapses.”
A patchwork quilt of regulation
Despite these massive risks, international regulation of stablecoins remains a patchwork quilt. While the U.S. and EU slowly try to rein in the chaos, many emerging markets lack the capacity—or the political will—to do so. In countries like Argentina or Nigeria, stablecoins are already part of everyday life, even though no one really knows who’s behind them or how secure these systems truly are.
The New York Fed calls in its study for greater international cooperation to manage the risks. But political reality tells a different story: many countries fear that overly strict rules could stifle innovation, while others simply lack the resources to monitor the stablecoin market. It’s a dangerous game of playing with fire.
And now?
The Federal Reserve Bank of New York’s study is one of the first to clearly show how stablecoins could destabilize existing financial systems. In good times, they may serve a purpose—but during a crisis, they could become an uncontrollable accelerant.
For central banks and regulators, this means it’s five to midnight. Clear rules for stablecoins are urgently needed—before the next currency crisis overtakes them. Otherwise, we may well face a global financial crisis that’s not only harder to control but also faster, more brutal, and more devastating than anything we’ve experienced before. And that’s saying something.
