The stablecoin yield fight — who's allowed to pay you for holding a dollar token

This is the real fight behind GENIUS/CLARITY, and it splits the banking industry against itself.

The mechanics (fact)

• GENIUS Act (Jul 18, 2025), §4: a payment-stablecoin issuer may not pay holders "any form of interest or yield ... solely in connection with the holding" — effectively banning yield-bearing stablecoins at the issuer level. Reserves are 1:1 in cash / short T-bills / Treasury repo / MMFs.
• The loophole: the ban targets issuers, not third parties. Coinbase pays "platform rewards" on USDC; PayPal offers yield on PYUSD — the three-party model (issuer passes reserve interest to an exchange, which pays the holder).
• OCC is moving to close it: its NPRM would extend the ban to affiliates and third parties. Final rules targeted ~Nov 2026 (the one-year deadline was missed).
• The asymmetry that matters: a tokenized deposit (JPM Kinexys, The Clearing House network) stays inside the bank, can carry deposit insurance, and can pay interest as a deposit — so incumbents can still offer yield via deposits even as issuer-stablecoin yield is banned.

The two readings (one fact, one contested)

• Banks' position: yield-bearing stablecoins are deposit substitutes that would drain uninsured deposits (especially from smaller banks) and shrink lending — so close the loophole. (BPI's "closing the payment-of-interest loophole"; a White House research note and CRS model the bank-lending effects.)
• Crypto's position: Congress wrote the ban to apply to issuers on purpose; third-party rewards are lawful consumer choice; banning them protects bank net-interest-margin, not consumers.
• The untested hypothesis (labeled, not asserted): that the "protect small banks' deposits" argument is being used to enlist community banks against a rule that would actually let those same community banks (and neobanks/chains) out-pay the megabanks on rate. It is checkable against the lobbying record — that's what task #225 does.

Why it's not "banks vs crypto"

Banks are not monolithic. The largest banks (BPI/ABA-leaning) benefit from a broad yield ban that protects margin and pushes value into their own tokenized-deposit and stablecoin consortia; community banks (ICBA) have a distinct interest and have begun their own tokenized-deposit coordination (BankChain Alliance — task #227). The yield rule's real effect may be distributional within banking, not just bank-vs-crypto.

The tie back to the map's spine

GENIUS reserves must sit in T-bills/repo/MMFs, so stablecoin growth is a structural Treasury-bill buyer — which is exactly why an over-indebted sovereign has reasons to want a large, compliant stablecoin float (the fiscal-trap rail). The yield fight decides who captures the spread on that float.
