Waller: Dollar Stablecoins Could Export US Monetary Policy

Federal Reserve Governor Christopher Waller told an economics conference in Croatia on Sunday that dollar-backed stablecoins could extend the reach of US monetary policy into other economies. Countries that adopt these digital assets may end up importing US monetary conditions alongside the tokens.

The comment, delivered at the 32nd Dubrovnik Economics Conference and reported by Bloomberg, signals a notable openness from a senior Fed official to the cross-border implications of privately issued dollar-pegged tokens. Waller described stablecoins as payment tools rather than a source of concern, saying they introduce competition into the payments sector and do not pose an inherent threat.

His remarks arrive as Washington lawmakers debate stablecoin regulation under the Digital Asset Market Clarity Act and as UK officials take a markedly more cautious stance. The divergence between the two largest Western economies over stablecoin oversight creates a policy gap that could affect where issuers domicile operations and how users access liquidity.

Why Waller Treats Stablecoins as Monetary Policy Tools

Waller's framework treats dollar stablecoins as passive transmission mechanisms. A user in a foreign economy holding a token fully backed by US Treasuries or cash is, in effect, exposed to US dollar short-term rates and the Fed's policy stance. If the Fed raises rates, the yield on the reserve assets rises, and stablecoin holders benefit indirectly without their local central bank adjusting policy.

The Mechanism: Dollar-backed stablecoins as passive transmission channels

The transmission works through the reserve composition. Major stablecoins such as USDT and USDC hold the bulk of their reserves in US Treasuries, reverse repo agreements, and cash. When the Fed tightens, the yield on those reserves increases. A stablecoin holder in a country with a different monetary regime effectively gains access to US dollar returns. Waller's point is that this effect is indistinguishable from importing US monetary conditions.

For a country with a weak currency or capital controls, widespread adoption of dollar stablecoins could erode the local central bank's control over domestic money supply. That is precisely why some emerging-market regulators have moved to restrict or ban stablecoin usage. Waller's framing suggests the Fed sees this as a feature, not a bug.

Waller's Position: Payment Competition, Not Financial Stability Risk

He explicitly said stablecoins do not pose an inherent threat. That contrasts with the view of many central bankers who focus on redemption risk during stress, the possibility of runs on issuers, and the lack of lender-of-last-resort backstops. Waller's confidence may reflect the Fed's experience with the Payment Stablecoin Act proposals that require 100% backing and restrict rehypothecation. If issuers are fully reserved with short-duration Treasuries, the risk of a run is far lower than the fractional-reserve model that triggered bank failures historically.

The BOE's Counterargument: Redemption Risk and the Coming Wrestle

Bank of England officials offered a contrasting perspective at the same conference. Megan Greene, a member of the BOE's Monetary Policy Committee, questioned whether stablecoins would remain dominant over the long term. She argued that tokenized bank deposits could eventually become the preferred form of digital money, offering the same programmability with deposit insurance and regulatory oversight.

Greene's Bet on Tokenized Deposits

Greene described the competition among CBDCs, stablecoins, and tokenized deposits as a race where all three may coexist. Her bet is that tokenized deposits gain the most momentum because they sit inside the existing regulatory perimeter. If she is right, the dollar stablecoin export thesis becomes less relevant: institutional users would instead hold tokenized dollars issued by regulated banks, not by separate stablecoin issuers.

Bailey's Warning on Redemption Pressures During Stress

BOE Governor Andrew Bailey went further. Earlier this month he warned that regulators face a difficult confrontation with Washington over stablecoin oversight. He described global payment use cases as requiring common international standards and predicted a likely “coming wrestle” with US authorities.

Bailey's core concern is redemption liquidity. He has argued that some stablecoins may not be easily redeemable during periods of market stress and that countries could face redemption pressures if dollar-backed stablecoins become widely used across borders. A sudden rush to redeem could force issuers to sell Treasuries into a falling market, amplifying volatility. That scenario would directly harm the monetary transmission mechanism Waller praised.

The UK's Proposed Stablecoin Rules: A Test Case for Scale

The UK has proposed one of the most specific stablecoin frameworks in the developed world. Under November 2025 proposals, issuers of pound-backed stablecoins would be required to hold 40% of reserves as non-interest-bearing deposits at the Bank of England. Individual users would face temporary holding limits of £20,000.

The Legislative Clock in Washington

In the US, the Digital Asset Market Clarity Act remains the most significant crypto market structure bill before Congress. Disagreements over whether stablecoin issuers and platforms should be allowed to offer yield have complicated its progress.

The Yield Debate as Sticking Point

Some lawmakers want to allow stablecoins to pay yield directly, which would blur the line between a payment token and a security. Others argue that yield-bearing stablecoins require full SEC registration. The deadlock keeps the legislative path uncertain. Senator Cynthia Lummis of Wyoming warned over the weekend that the US could lose ground to countries including China if Congress fails to pass crypto legislation this year.

Lummis Warns of Losing Ground to China

China has banned crypto trading but is pushing its digital yuan aggressively for cross-border payments. Lummis' warning is not abstract: if dollar stablecoins lack a clear legal framework, non-US issuers may choose to operate under EU or Asian rules instead. The dollar export thesis Waller described depends on stablecoins being domiciled in jurisdictions that respect US sanctions and oversight. A fragmented regulatory environment weakens that link.

What Confirms the Dollar Stablecoin Thesis – and What Weakens It

Signs That Reinforce Waller's View

Passage of US stablecoin legislation with 100% reserve requirements and clear federal oversight. That would give issuers a stable regulatory footing and encourage global adoption.

UK relaxation of the 40% reserve rule and removal of the £20,000 cap, allowing GBP stablecoins to compete. Even if they compete, the dollar still dominates.

Continued growth of US Treasury reserves in the largest stablecoins. As long as USDT and USDC hold Treasuries, the link to Fed policy remains direct.

Emerging-market dollarization via stablecoins in countries like Argentina, Turkey, and Nigeria, where local currencies are under pressure. That trend is already visible.

Risks That Undermine the Framework

A redemption crisis at a major stablecoin issuer during a Treasury market dislocation. A forced sale of reserve assets would create a negative feedback loop and invite regulation that restricts stablecoin usage.

Regulatory divergence between the US and other G7 governments. If the EU and UK impose rules that make dollar stablecoins difficult to use at scale in their markets, the global reach narrows.

Tokenized bank deposits gain adoption. If large banks offer programmable dollars with FDIC insurance and full reserve backing, the stablecoin cost advantage disappears.

Congress fails to pass stablecoin legislation, leaving a patchwork of state-level rules that create compliance complexity and limit issuer growth.

Next Decision Point for Stablecoin Markets

The next concrete catalyst is the UK review of its stablecoin proposals. A decision on the 40% reserve requirement and the £20,000 cap is expected in the coming months. If the BOE relaxes both, merchants and exchanges will have a clearer path to offer GBP stablecoins. If the rules remain tight, the UK market will continue to rely on dollar tokens, and the BOE's own warnings about cross-border dollar dominance become a self-fulfilling prediction.

In Washington, the clock is running on the Digital Asset Market Clarity Act before the 2026 midterm elections. Waller's speech gives proponents a powerful argument: dollar stablecoins amplify US monetary power abroad. Whether that argument translates into law depends on a yield debate that has no easy compromise.

For now, the risk event is not a single incident but a policy divergence. Traders holding large stablecoin positions should watch the UK reserve review, the US legislative calendar, and the next Treasury market stress that tests Bailey's redemption thesis.
