Carolyn Wilkins, a member of the Bank of England’s Financial Policy Committee, indicated that the expansion of dollar-denominated stablecoins may reinforce the US dollar’s global dominance. Speaking at Queen’s University Belfast, she explained that these digital assets facilitate cross-border settlement and expand access to dollar-linked assets, thereby increasing demand for US government debt held as reserves.
Wilkins cited data showing that major issuers Tether and Circle held nearly $150 billion in Treasury bills at the end of 2025, having purchased approximately $33 billion during that year. The stablecoin market currently exceeds $300 billion in circulation, with the US dollar accounting for 98% of its value. While this trend supports dollar hegemony, Wilkins warned that mass redemptions at scale could force issuers to sell Treasurys, potentially amplifying volatility in stressed markets.
The assertion by a senior Bank of England official highlights a paradoxical dynamic where crypto-native instruments are inadvertently strengthening traditional fiat infrastructure. By linking stablecoin growth directly to increased demand for US Treasurys, the commentary underscores how digital dollars function less as competitors to sovereign currency and more as extensions of existing financial plumbing. This reinforces the 'first-mover advantage' of the greenback, suggesting that regulatory frameworks favoring dollar-pegged assets may accelerate institutional integration rather than disrupt it.
However, the dual nature of this relationship introduces significant systemic risk considerations. While steady issuance supports bond markets, the potential for rapid redemption cycles creates a liquidity mismatch that could exacerbate stress in fixed-income sectors. For policymakers, the challenge lies in balancing innovation with stability, particularly as UK regulators attempt to foster pound-denominated alternatives through sandboxes and new rules. The divergence between the mature, dollar-dominated stablecoin ecosystem and slower-moving local initiatives suggests that network effects will likely continue to favor the US dollar in the near term.
