Bank of England’s Carolyn Wilkins argues that booming demand for dollar stablecoins could boost the dollar’s dominance and drive significant US Treasury flows—but warns that large-scale redemptions may amplify volatility.
The rapid expansion of dollar stablecoins—now topping $300 billion in circulation—has transformed Tether and Circle into major US Treasury investors, with implications that reach well beyond crypto.
The Crypto-Dollar Pipeline
Bank of England policy maker Carolyn Wilkins, in a speech at Queen’s University Belfast, outlined how the growth of dollar-denominated stablecoins is reshaping the international financial landscape. The largest stablecoin issuers, including Tether (USDT) and Circle (USDC), collectively held nearly $150 billion in US Treasury bills at the close of 2025. During that year alone, issuers purchased approximately $33 billion more, reflecting surging demand for digital dollars. According to Wilkins, this transforms stablecoin platforms from niche payment rails into key players in the sovereign debt ecosystem. The overwhelming dominance of US-pegged stablecoins (accounting for 98% of value) heightens the dollar’s reach by enabling cross-border settlements and offering dollar-linked assets outside US borders.
The feedback effect goes both ways. As dollar-linked stablecoins grow, so does their need for safe, liquid reserves—historically, short-dated US Treasurys. This institutionalizes new demand for government debt, with stablecoin issuers stepping in as consistent buyers. It also creates a link between on-chain activity and traditional capital markets: every new USDT or USDC minted is at least partially backed by allocations to Treasurys or similar assets. Policymakers watch this shift closely: while it channels new capital into the US debt market, it also exposes sovereign bonds to flows driven by digital asset cycles.
Volatility Risk From Redemption Waves
Wilkins cautioned against viewing stablecoin demand as a one-way stabilizer. At sufficient scale, mass redemptions—if triggered by sudden loss of confidence or regulatory pressure—could force issuers to unwind sizable holdings of US Treasurys. Given stablecoins’ current scale, such procyclical selling could inject volatility into Treasury markets, especially during periods of already heightened stress. In this aspect, stablecoins become a new transmitter of liquidity risk, not just for crypto platforms but for the broader financial system. The industry’s first-mover advantage in dollar-pegged issuance amplifies both the benefit to the dollar and the potential cost during turbulent phases.
Issuers’ Treasury reserves can serve as a buffer, but only so long as redemptions remain moderate and predictable. The more stablecoin supply grows, the more Treasurys come to depend on flows from crypto-native demand—and the greater the risk if outflows are correlated or sudden. This dependency could stress market functioning at the margin, especially if digital asset sentiment diverges from traditional fixed-income fundamentals.
Operational Watchpoints for Investors
- Sustained stablecoin inflows into Treasurys could further anchor the dollar’s global dominance if flows remain positive and dispersed.
- A spike in redemptions concurrent with macro stress could test the assumed safe-haven status of Treasurys, introducing new liquidity dynamics.
- Monitoring shifts in reserve composition (e.g., longer-dated vs. shorter-dated Treasurys) could reveal evolving risk appetites among issuers.
- A regulatory clampdown or loss of access in key non-US markets might accelerate outflows, forcing reserve liquidations with spillover risk.
Where the Stablecoin-Treasury Feedback Loop Goes From Here
The prospect of accelerating stablecoin adoption tying the US dollar even more closely to digital asset flows is already influencing central bank policy debates. Regulatory clarity, diversification of reserve strategies, and the stability of US Treasurys as the world’s risk-free asset remain active fronts. Whether stablecoins ultimately reinforce or destabilize the global role of the dollar will depend on how these linkages weather stress cycles. As stablecoin reserves integrate more deeply with sovereign debt markets, tracking the scale and direction of these flows will be increasingly critical for both crypto-native and traditional market participants.

🧠 HafidWatch Take
If stablecoin redemptions were consistently absorbed through alternative liquidity channels without triggering any forced sales of U.S. Treasurys, then the prevailing view that stablecoin scale amplifies volatility in government debt markets would be flawed. This would indicate stablecoin reserves function as a stabilizing force rather than a source of systemic risk, undermining the article’s fundamental framing of stablecoins as potential accelerants of Treasury market turbulence.
A historical parallel can be drawn to the Bank of England’s experience during the 1992 Sterling crisis, when off-balance-sheet currency exposures initially masked vulnerabilities in the pound. Much like that episode, current market focus on dollar dominance neglects how stablecoin proliferation in non-U.S. jurisdictions could inadvertently import Federal Reserve policy shocks through digital rails. This externalization of volatility risks via stablecoins highlights a subtler layer of cross-border monetary influence that remains underappreciated in mainstream analysis.
