Dollar stablecoins could blow up financial stability. That’s the stark warning from the Bank for International Settlements, which wants regulators worldwide to get their act together fast. The Switzerland-based institution thinks these tokens might soon compete with traditional money if the market keeps growing at its current pace.
BIS General Manager Pablo Hernández de Cos drew some uncomfortable parallels between big dollar stablecoins and exchange-traded funds. He pointed to fees, redemption terms, and how these tokens sometimes drift away from their one-dollar peg when people trade them on secondary markets. The structure creates dangerous feedback loops, according to de Cos. Issuers don’t actually hold cash—they park user funds in short-term government debt and bank deposits instead. If everyone rushes to cash out at once, issuers would need to dump Treasury bills and yank money from banks. That kind of fire sale would send shockwaves through markets that can’t really afford more volatility right now.
Things get messier when you look at how people actually use these tokens. De Cos flagged serious gaps in financial integrity controls because stablecoins run on public blockchains that anyone can access. Plenty of users rely on unhosted wallets, which means a huge chunk of stablecoin transactions happen completely outside the usual anti-money-laundering checks. No banks watching. No compliance officers asking questions. That makes stablecoins pretty attractive for people moving dirty money or funding terrorism, unless authorities clamp down hard at the points where crypto meets traditional banking.
Emerging Markets Face Currency Pressure
The dollarisation problem hits different in emerging markets. Households there are already using dollar-pegged tokens to stash savings offshore, and some are starting to use them for everyday purchases too. Wider adoption would kneecap local monetary policy. Central banks lose their grip when people ditch the local currency for digital dollars. And stablecoins offer fresh ways to dodge capital controls that governments use to manage money flows.
Local currencies take a beating in the process. When citizens can easily switch to dollar stablecoins, it puts downward pressure on domestic exchange rates. Policymakers in these countries are basically watching their economic toolkit shrink in real time. The situation gets harder to manage as more people discover they can hold dollars on their phones without needing a foreign bank account.
Major jurisdictions are scrambling to write rulebooks. The European Union rolled out its Markets in Crypto-Assets Regulation. The UK is finalizing rules for fiat-backed tokens. Switzerland just published new guidelines for Swiss franc-linked coins. All three demand full reserve backing and want direct oversight of whoever issues these things. But the approaches don’t really line up.
Fragmented Rules Create Loopholes
De Cos warned that mismatched standards could fracture markets. When one place has tight rules and another doesn’t, activity just migrates to wherever regulators ask fewer questions. The whole point of coordination falls apart if every jurisdiction does its own thing. Cross-border risks slip through the cracks when there’s no unified framework.
The BIS thinks stablecoins could start behaving like investment funds if usage scales up enough. These tokens would become deeply wired into the global financial system, creating the same kinds of systemic risks that traditional financial instruments carry. Right now, most people see stablecoins as a crypto thing. But if they grow big enough, they’ll be everybody’s problem.
Capital control evasion worries the BIS too. Emerging market governments use these controls to prevent destabilizing money outflows during crises. Stablecoins punch holes in those defenses. Someone in a country with strict capital controls can now move value across borders just by transferring tokens to a wallet address. No paperwork. No bank approval. The money’s gone before authorities even know it moved.
Public blockchains and unhosted wallets make enforcement nearly impossible under current systems. Traditional finance has chokepoints where regulators can monitor transactions and flag suspicious activity. Crypto doesn’t work that way. Once tokens leave an exchange and land in a private wallet, tracking becomes incredibly difficult. The BIS wants much stronger checks at the entry and exit ramps where crypto platforms connect to banks.
The reserve backing question matters more than it seems. Full reserves sound safe, but what counts as a reserve? If issuers hold mostly short-term government debt, they’re exposed to interest rate swings and liquidity crunches. A spike in redemptions could force them to sell bonds at a loss during a market downturn. That creates losses that might prevent some users from getting their full dollar back.
Redemption rights vary wildly between issuers too. Some promise instant redemptions for everyone. Others have minimum amounts or processing delays. A few reserve the right to suspend redemptions during “extraordinary circumstances,” whatever that means. De Cos pointed out these differences matter a lot when stress hits the system. Users might think they can always get their dollar back, but the fine print tells a different story.
The BIS didn’t mince words about the need for global coordination. Without aligned standards, strict regulatory regimes in some countries won’t accomplish much if activity just shifts elsewhere. The organization wants regulators to work together on common rules that close loopholes and address risks that cross borders. So far, that kind of coordination remains more aspiration than reality.
Stablecoin transactions already total billions of dollars daily, and growth isn’t slowing down. The longer regulators wait to coordinate, the harder it gets to put guardrails in place without disrupting markets. But moving too fast with conflicting rules could be just as bad, fragmenting liquidity and pushing users toward less regulated corners of the crypto world.
Frequently Asked Questions
What specific risks did Pablo Hernández de Cos identify with stablecoin reserve backing?
De Cos noted that issuers back stablecoins with short-term government debt and bank deposits rather than cash, which could force mass sell-offs of Treasury bills and bank withdrawals during redemption surges, increasing market volatility.
How do stablecoins threaten monetary policy in emerging markets?
Stablecoins enable households to hold offshore dollar savings and make domestic payments in dollars, which weakens central banks’ control over local monetary policy and puts downward pressure on domestic currencies.
What regulatory frameworks are major jurisdictions developing for stablecoins?
The European Union implemented MiCA regulations, the UK is finalizing rules for fiat-backed tokens, and Switzerland published guidelines for franc-linked coins—all requiring full reserve backing but with different implementation approaches.
