The Bank of England is reconsidering key parts of its proposed stablecoin rules, softening its earlier stance on limits to holdings and stringent reserve requirements after industry pushback, a shift that could influence liquidity, issuance economics, and investor behavior across crypto markets that rely on fiat-tracking tokens for payments.

Key Drivers

Sarah Breeden, the Bank’s deputy governor for financial stability, said officials are weighing alternative approaches to containing risks as the sector grows. She noted that the initial thinking drew on lessons from recent liquidity strains and bank runs, including heavy deposit withdrawals at Silicon Valley Bank in 2023 that coincided with volatility in major dollar-pegged tokens. Breeden added that policymakers will “look hard” at whether parts of the approach were “overly conservative,” and acknowledged the industry’s preference to hold a larger share of interest-earning assets rather than non-yielding cash-like buffers.

The discussion centers on how much of an issuer’s reserves must sit in the most liquid forms and how much can be deployed into instruments that earn yield. Under the Bank’s proposal described by market participants, UK stablecoin issuers would be able to earn interest on only 60% of reserves. By comparison, Circle has held about 88% of USDC reserves in Treasury bills and repos, according to Andres Monty, CEO of stablecoin risk intelligence platform Range. That gap matters for token economics and, by extension, for how competitive GBP-pegged stablecoins can be versus alternatives in other jurisdictions.

Breeden emphasized that the central bank is examining whether there are different ways to manage what it views as a material risk as stablecoins scale into mainstream use. The underlying policy goal remains the same: to ensure liquidity and predictable redemption during stress, while making space for issuers to operate sustainably.

Market Movement

Stablecoins—crypto tokens intended to mirror fiat currencies such as the dollar or pound—typically seek price stability by holding reserves in cash, government debt, or similar assets. Though price quotes were not central to the Bank’s remarks, the mechanics under discussion go to the heart of how these tokens function in payments and within the digital asset ecosystem. Rules that determine the composition and liquidity of reserves help anchor redemption confidence in normal times and during shocks. They also shape the economic incentives for issuers, which, in turn, can affect token availability, spreads, and trading activity, particularly for GBP-denominated use cases.

For UK issuers, the calibration of a reserve “floor” has a direct cost. Monty estimated that at short-dated gilt yields of about 4%, the proposed split—where only 60% of reserves earn yield—could impose a roughly £11.2 million annual drag for every £1 billion of stablecoins in circulation. He said that cutting the floor portion from 40% to 20% would “roughly halve that drag,” bringing UK stablecoin economics closer to regimes under MiCA and among U.S. issuers.

Investor Reaction

Industry response has framed the Bank’s latest comments as a constructive signal. Katie Haries, Coinbase’s head of policy for Europe, said the central bank appears willing to revisit its stablecoin plans. She argued that “a cap on stablecoin holdings is a cap on innovation,” warning that strict limits could weigh on the UK’s competitiveness. Haries added that the Bank’s aim to create a regime where stablecoins can succeed and “deliver benefits to the users” aligns with what both the crypto asset industry and everyday users are asking for.

Market participants are also focused on potential jurisdictional effects. Monty cautioned that onerous holding caps could spur arbitrage, including the possibility that a leading GBP stablecoin might be issued from another market rather than the UK. He suggested the Bank faces a strategic choice between directly regulating the most-used pound-pegged token or seeing issuance shift offshore, noting that investors place a premium on redemption certainty even when it comes at the expense of a few basis points of yield.

Regulatory Context

Oversight in the UK is expected to be split: the Financial Conduct Authority would supervise non-systemic issuers, while the Bank of England would regulate stablecoins that become widely used for payments. That framework is being refined as officials consider how to balance liquidity safeguards with the operational realities of token issuance and redemption. The Bank’s evolving messaging suggests a move away from a strict hard-limit model and toward a more flexible regime built around liquidity, redemption, and issuer protections.

In a related signal, Sasha Mills, the Bank’s executive director for financial market infrastructure, recently said the institution is treating stablecoins as “a new form of money” and expects to accept applications from would-be systemic stablecoin issuers by year-end. The timeline underscores how regulatory architecture and market development are moving in tandem, with the Bank seeking to influence the design of tokens that could become embedded in everyday payment flows.

Governor Andrew Bailey, meanwhile, has warned of a potential clash with the U.S. over stablecoin standards. He argued that looser redemption rules for dollar-based tokens could transmit stress into the UK during periods of market turmoil. Those comments highlight a broader international coordination challenge: because stablecoins cross borders quickly, divergences in reserve quality or redemption practices can redirect pressure from one jurisdiction to another when liquidity is tight.

Broader Impact

The Bank’s readiness to revisit reserve floors and holding limits is being read by many in crypto markets as an attempt to craft a regime that preserves stability while keeping the UK attractive for issuers and institutional users. Monty pointed to the potential for a Bank-supported liquidity backstop—an option he described as unique relative to other jurisdictions—that could bolster redemption certainty. While such a facility remains under consideration, market participants see any credible enhancement of liquidity support as a factor that could deepen institutional engagement with pound-pegged tokens.

For traders, payment providers, and treasury teams that rely on stablecoins, the policy calibration will influence where and how pound-linked liquidity develops. Clarity on reserve composition, day-to-day liquidity management, and redemption mechanics would set expectations for market functioning during stress and calm alike. For issuers, small changes to the reserve split can meaningfully alter the margin profile of a token and determine whether UK-based issuance remains competitive next to regimes where a greater share of reserves can earn yield.

The Bank’s message is that stability and usability are not mutually exclusive. As officials reassess holding caps and the liquidity floor in light of recent stress episodes and industry feedback, investors will watch for specifics that translate intent into operational rules. The outcome will help decide how GBP-denominated stablecoins scale, how they compete with dollar-pegged alternatives, and how resilient redemption remains when the next bout of market volatility arrives.
