The Senate Banking Committee’s failure to advance the CLARITY Act has created an unintended experiment on stablecoin rewards, pitting the American Bankers Association’s $6.6 trillion deposit-at-risk warning against the White House Council of Economic Advisers’ $2.1 billion lending-effect estimate. The legislative gridlock leaves exchanges free to offer yields on stablecoins while Congress debates whether such incentives genuinely threaten bank deposit bases or represent minimal economic friction.
The Competing Risk Frameworks
The ABA’s $6.6 trillion figure reflects the total US commercial bank deposit base ($19.1 trillion), treating all deposits as theoretically vulnerable to stablecoin competition. Banks argue that exchange-funded rewards on stablecoins—cash back, referral bonuses, promotional yields—create functional deposit substitutes without the reserve requirements, capital rules, or insurance costs that constrain traditional banking. The White House CEA’s April rebuttal projected a $2.1 billion lending reduction if stablecoin yield prohibitions passed, representing a 0.02% increase in overall lending. Standard Chartered’s $500 billion deposit outflow forecast by end-2028 occupies middle ground, bounded and time-specific. The stablecoin market stood at $320 billion as of April 27, representing 1.66% of the deposit base. If stablecoins captured $500 billion entirely through deposit displacement, the share would reach 0.96% of total deposits.
Market Data and Regulatory Response
The OCC and FDIC proposed anti-evasion rules in March and April, respectively, targeting deposit-flight mechanics but neither rule has been finalized. Galaxy Research assessed 50-50 odds of CLARITY enactment this year, signaling legislative uncertainty. The BIS February working paper documented $3.5 billion in five-day stablecoin inflows lowering three-month T-bill yields by 2.5-3.5 basis points, establishing empirical proof that stablecoins already connect to Treasury markets and deposit substitution dynamics. The White House CEA cited an $800 million net welfare cost from yield prohibition, suggesting broader economic trade-offs beyond lending volume. Congressional hearings on stablecoin rewards have spanned 18 months without resolution.
Global Regulation Narrows the Debate
The EU’s MiCA framework explicitly prohibits e-money token issuers from paying interest, establishing a regulatory precedent for yield caps. Hong Kong’s license-based stablecoin regime similarly restricts reward mechanisms. The BIS cross-jurisdiction analysis indicates global policymakers view stablecoin yields as a deposit-competition lever requiring explicit control. The CLARITY Act’s stall has left US exchanges operating in a regulatory vacuum while other jurisdictions move toward explicit restrictions, potentially creating arbitrage opportunities for offshore stablecoin issuers and exchanges.
Next Milestones and Unresolved Variables
The CLARITY Act addresses token classification, exchange registration, software carveouts, and DeFi provisions, but core disputes over stablecoin yield language remain unresolved. If enacted, the GENIUS Act framework would prohibit stablecoin rewards explicitly, with effectiveness 18 months post-enactment or 120 days after final regulations. OCC and FDIC final rules remain unpublished. No official timeline confirms when Senate Banking will resume deliberation or whether the Trump administration’s pro-crypto stance will accelerate legislative movement.
