Bank of England warns of stablecoin oversight clash with US

Andrew Bailey, Governor of the Bank of England, is not mincing words about what he sees coming: a regulatory “wrestle” with the United States over how stablecoins should be governed. Speaking at a conference on May 8, Bailey laid out a scenario where weak US redemption standards could send shockwaves across the Atlantic, turning the UK into an unwilling backstop during the next bout of market panic.

The concern is straightforward. If dollar-backed stablecoins lack robust guarantees that holders can actually cash out at face value, a crisis could trigger mass redemptions. And Bailey believes a meaningful chunk of those redemptions would land in UK markets, importing instability from an asset class the UK didn’t design and doesn’t control.

The $317 billion problem

The global stablecoin market now exceeds $317 billion, overwhelmingly dominated by USD-pegged tokens like USDT and USDC. That concentration is the core of Bailey’s worry.

Bailey pointed to the 2022 collapse of TerraUSD as exhibit A. That implosion wiped out tens of billions in value almost overnight, and it happened with a token that was, in theory, algorithmically pegged to the dollar. The lesson, in Bailey’s framing, is that cross-border contagion from poorly regulated stablecoins isn’t theoretical. It already happened once.

Where the US and UK diverge

The tension Bailey is flagging isn’t abstract. It maps directly onto specific legislative efforts on both sides of the Atlantic.

In the US, the GENIUS Act represents the most significant stablecoin legislation to date. The bill is part of a broader push, heavily influenced by traditional banking institutions, to impose restrictions on stablecoins that would protect conventional deposit bases. Recent US Senate discussions have included a May 2026 markup examining whether to ban yields on stablecoin balances entirely, a move that would fundamentally change how these tokens compete with bank accounts.

The UK, meanwhile, has been moving in its own direction. In November 2025, the Bank of England proposed a distinct set of limits for GBP-denominated stablecoins, including a cap of £20,000 for individual holdings and a requirement that 40% of reserves be held in central bank deposits.

Bailey emphasized that stablecoins must maintain their nominal value with strong safeguards, particularly around redemption rights. His argument is that if US rules permit looser redeemability standards, the resulting products will still circulate globally, and their weaknesses will become everyone’s problem.

Why this matters for investors

Regulatory fragmentation between the world’s two largest financial centers is not a niche concern. It strikes at the heart of what makes stablecoins useful in the first place: the promise of seamless, borderless transactions that settle at a predictable value.

There’s also a second-order risk that Bailey alluded to directly. In a crisis scenario, if US-regulated stablecoins prove unreliable, capital doesn’t just vanish. It moves. A flight to perceived safety could see investors pile into UK-regulated alternatives or UK financial markets more broadly, straining systems that weren’t built to absorb sudden inflows of that magnitude.

For anyone holding or building on stablecoins, the takeaway is to watch the legislative calendars in both Washington and London very closely. The GENIUS Act’s progress, the Bank of England’s finalization of its reserve and holding limits, and any bilateral discussions between regulators will be the real signals.
