Federal Reserve governor Christopher Waller and Bank of England chief economist Megan Greene expressed sharply divergent views on stablecoins at a conference Sunday, signaling fracture lines in how major central banks assess digital currency risks.
Waller framed stablecoins as tools that extend U.S. monetary policy reach. His comments suggest the Fed views stablecoins less as a threat to traditional banking infrastructure and more as a mechanism that propagates dollar dominance in digital markets. This positions the Fed closer to acceptance of private stablecoin ecosystems provided they remain dollar-denominated.
Greene took the opposite stance. The Bank of England economist predicted stablecoin adoption will collapse as quickly as it rose, dismissing them as a temporary phenomenon that regulators need not fear. Her remarks reflect British skepticism about stablecoins' long-term viability, suggesting the BoE believes market forces alone will erode user confidence without heavy-handed regulation.
The split reflects deeper divisions in transatlantic crypto policy. U.S. regulators have pursued selective oversight through frameworks like the stablecoin bill, which would require issuers to hold backing reserves. The UK has taken a lighter touch, focusing on monitoring rather than preemptive rules.
Waller's comments come as USDC and USDT remain the dominant stablecoins by market cap, with combined value exceeding $130 billion. Both tokens anchor DeFi liquidity pools and serve as primary on-ramp assets on major exchanges. If the Fed genuinely views stablecoins as policy extensions, it signals tacit acceptance of their systemic role.
Greene's dismissal contrasts with rising institutional adoption. Stablecoins processed record transaction volumes in 2024, driven by corporate treasury adoption and institutional trading. Markets clearly haven't priced in imminent collapse.
The disagreement matters for stablecoin tokenomics and adoption curves. A regulatory framework that encourages stablecoins, as Waller's stance implies, would solidify their role as digital dollar proxies. Greene's prediction of decline suggests the
