FORWARD-LOOKING: The CLARITY Act Yield Compromise Would Create a Structural Deposit-Competition Problem Banks Cannot Solve With Rate Alone

How CLARITY Act Section 404's yield loopholes create a structural deposit-competition problem banks can't solve by raising savings rates alone.

Note: This piece analyzes a scenario based on pending legislation (the Digital Asset Market CLARITY Act, H.R. 3633, Senate Banking Committee markup scheduled May 14, 2026, at 10:30 a.m. ET). The bill has not yet been enacted. All analysis is forward-looking and contingent on passage.

The conventional framing of the CLARITY Act stablecoin fight is political: banks versus crypto, incumbents protecting turf, another Washington lobbying cage match. That framing is incomplete. The problem a bank's treasury officer should be modeling is structural. If Section 404 passes in its current form, banks will face a competitor that can offer consumers more yield on the same dollar not because the competitor is better at banking, but because the competitor has been architecturally removed from most of the cost categories that define banking. Raising your high-yield savings rate does not solve that problem. It compounds it.

This is not a prediction about what Congress will do. It's a model of what happens to deposit economics if Section 404 survives markup in recognizable form — which, as of today, Polymarket prices at roughly 62%.

What Section 404 Actually Says — and What It Doesn't Close

The compromise language released by Senators Thom Tillis (R-N.C.) and Angela Alsobrooks (D-Md.) and codified as Section 404 of the CLARITY Act draft circulating ahead of Thursday's markup prohibits covered parties from paying any form of interest or yield — "whether in cash, tokens, or other consideration" — to a "restricted recipient" under two specific conditions: (a) "solely in connection with the holding" of payment stablecoins, or (b) "on a payment stablecoin balance in a manner that is economically or functionally equivalent to the payment of interest or yield on an interest-bearing bank deposit."

Read that carefully. The prohibition contains two structural escape hatches that the banking trade groups correctly identified in their May 8 joint letter to Senate Banking Committee Chairman Tim Scott and Ranking Member Elizabeth Warren.

First, the word "solely." A covered party prohibited from paying yield solely for holding a stablecoin can pay yield for holding a stablecoin plus any ancillary condition — joining a membership program, transacting once a month, clicking an acknowledgment. The "solely" qualifier does most of the damage. Any de minimis activity requirement attached to an otherwise passive reward restructures that reward from prohibited to permitted.

Second, Section 404 explicitly carves out "rewards or incentives based on bona fide activities or bona fide transactions." The bill also permits rewards calibrated by reference to duration, balance, and tenure. As the banking trades' May 4, 2026 statement put it: "Overtly incentivizing the idle holding of payment stablecoins for extended periods of time, and for specific balances, would negate the goals of the upfront prohibition (to deter deposit flight) while tying rewards directly to how much/long customers hold payment stablecoins in wallets or exchanges." The May 8 joint letter — signed by the American Bankers Association, Bank Policy Institute, Consumer Bankers Association, Financial Services Forum, Independent Community Bankers of America, and National Bankers Association — escalated the point, arguing that retaining the balance-and-tenure carve-out would negate the prohibition's stated purpose.

That is a precise legal description of a high-yield savings account, offered through a different instrument. Balance-tiered, duration-sensitive rewards on a dollar-pegged, redeemable instrument are functionally a savings rate — whether or not they pass the bill's "economically or functionally equivalent" test, which will be an inherently contested, fact-intensive inquiry the moment the first enforcement action is filed.

The trade groups urged that subsection (3)(B) — the functional-equivalence clause — be removed entirely, and that the "solely" qualifier be stripped from the prohibition's core. Those amendments have not been incorporated into the draft text circulating ahead of Thursday.

The Cost-Structure Gap That Rates Cannot Close

The structural problem, in the plainest terms:

A stablecoin issuer receives a dollar. Under the GENIUS Act framework — which CLARITY builds on — that issuer parks the dollar in short-duration U.S. Treasuries, Treasury repos, or central bank reserves. It earns near the risk-free rate. It carries no credit risk in its reserve portfolio. It owes no FDIC deposit insurance assessment. It holds no regulatory capital against credit exposure, because it has none. It bears no liquidity coverage or net stable funding obligations tied to a fractional-reserve lending model.

A bank receives the same dollar. It deploys it into loans and securities. It pays an FDIC assessment scaled to its risk profile. It holds risk-based capital against its loan book. It maintains LCR and NSFR buffers. Its treasury function has a cost-of-funds floor it cannot go below without destroying net interest margin. Even its highest-rate deposit product — a high-yield savings account, a 12-month CD, a sweepable money market account — is priced against all of those structural costs.

The arithmetic consequence: a stablecoin issuer's marginal cost of paying yield is the risk-free rate minus thin operating expenses. A bank's marginal cost of paying yield is the risk-free rate minus operating expenses minus FDIC assessment, regulatory capital charges, liquidity buffer costs, and the internal funds transfer price needed to keep the lending book solvent. Those deductions are not trivial. The gap between the risk-free rate and a bank's all-in cost of funding a marginal deposit dollar is material — and it is the gap a stablecoin issuer does not have to cover.

The result is that a stablecoin issuer can sustainably offer holders meaningful yield through the Section 404 "bona fide activity" carve-out at a rate banks cannot match without compressing NIM on the assets that rate is funding. This is a cost problem, not a pricing problem. The bank's regulatory cost structure is the binding constraint.

The BPI made the broader macroeconomic version of this argument in its May 8 blog post, authored by Bill Nelson. Drawing on a Federal Reserve analysis by Jessie Jiaxu Wang (December 2025), and on a crypto-industry-funded academic model by Lin William Cong (sponsors disclosed by BPI as Coinbase, Paradigm, PayPal, and Stripe), BPI concluded that yield-bearing stablecoins would destroy deposits — not recirculate them within the system. Under the Wang framework, the introduction of stablecoins would reduce bank lending by somewhere between $65 billion and $1.26 trillion, with the high end occurring if stablecoin issuers gain master-account access to the Federal Reserve. In Cong's own model, calibrated to match U.S. financial system behavior, $4 trillion in stablecoin circulation — a figure Cong himself cites as a plausible 2030 projection — would destroy roughly $3.7 trillion in bank deposits and reduce lending by approximately $2.7 trillion.

Those numbers sit at the high end of plausibility. But the mechanism is not implausible: when a better-yielding, dollar-pegged, liquid instrument exists outside the bank regulatory perimeter, households and businesses with transactional balances will migrate toward it. Banks will attempt to compete on rate. The competitor's cost structure does not include the categories banks are required to bear, so rate competition compresses bank margins faster than it slows the migration. Banks then resort to wholesale funding, which costs more and is less stable. Loans become more expensive. Credit supply contracts.

The ABA's April 2026 research framed the market expansion risk concretely: permitting yield-bearing stablecoins could expand the stablecoin market from roughly $300 billion today to $2 trillion, with growth coming predominantly at the expense of transactional bank deposits.

The Counterargument Worth Taking Seriously

The strongest case against this analysis runs as follows: deposit migration to stablecoins is not a one-way function of yield differentials. Transactional deposits are sticky for reasons rate alone does not capture — payroll direct-deposit infrastructure, bill-pay rails, overdraft protection, FDIC insurance as a behavioral anchor, and the simple friction of moving money to a wallet most consumers do not yet hold. Money-market funds have offered higher yields than bank deposits for four decades without collapsing the deposit base. The Wang and Cong figures assume frictionless substitution that empirical deposit behavior does not support.

That argument is correct on its premises and wrong on its conclusion. Money-market funds did not collapse the deposit base, but they did permanently restructure bank funding — pushing roughly $7 trillion into a parallel system and forcing banks into more expensive, less stable wholesale alternatives at the margin. The relevant question is not whether stablecoins replicate the bank run scenario at the tail of the Wang model. It is whether they extract enough transactional deposits to move the marginal funding cost curve. They do not need to win the entire deposit base. They need to win the price-sensitive sliver — and that sliver is exactly where balance-and-tenure-calibrated rewards target.

The Regulatory Arbitrage Section 404 Leaves Intact

The banking trade groups are not arguing that the prohibition on yield isn't tight enough in the abstract. They are identifying a specific arbitrage architecture that Section 404 creates and fails to close.

Under the current draft, a crypto exchange — a "covered party" — can operate a stablecoin rewards program tied to platform membership, transaction volume, or holding duration, provided the program is not solely a passive yield on the balance. PayPal's PYUSD, Coinbase's USDC distribution model, and an open-ended set of follow-on products can be structured as activity-based rewards that correlate closely with balance size and holding period.

The functional test — "economically or functionally equivalent to the payment of interest or yield on an interest-bearing bank deposit" — is form-based rather than substance-based. A rewards program that pays an annualized percentage to users who hold a threshold balance for 30+ days and complete one transaction per month is not formally equivalent to a savings rate. But it is economically indistinguishable from one. The household balance sheet sees no difference. The deposit migration dynamics are the same.

What would actually close the gap is threefold: (1) stripping the "solely" qualifier so any yield-adjacent reward tied to holding falls within the prohibition; (2) removing the balance-and-duration calibration permission, which directly enables savings-rate-equivalent program design; and (3) applying a substance-over-form standard to the functional equivalence test rather than a mechanical comparison to bank deposit mechanics. The banking trades' May 8 letter outlined each of these changes explicitly. None are reflected in the current manager's amendment.

The Western Union Signal

The immediacy of this scenario is no longer theoretical. On May 4, 2026 — one week before the Senate Banking Committee released the latest CLARITY Act text — Western Union announced the launch of USDPT, its U.S. dollar-denominated payment stablecoin, issued by Anchorage Digital Bank N.A. on Solana. USDPT's first deployment is institutional: agent settlement as an alternative to SWIFT. But Western Union has also announced a consumer-facing product, "Stable by Western Union," targeting 40+ countries in 2026, and is developing a Stable Card for consumer spending.

Western Union's stablecoin is not currently yield-bearing. That's the point. What Western Union has demonstrated is that a 175-year-old non-bank institution with global distribution can launch a regulated, dollar-pegged token in production time. The infrastructure layer is live. If Section 404 passes in current form, the question is not whether someone builds a yield-bearing product on that infrastructure — it's how quickly. The window between legislative enactment and market deployment is measured in months, not years.

What to Watch

Thursday's committee vote is the first gate. All 13 Republican members must vote yes; Chairman Scott has called this "the red zone," and as of Monday Senator John Kennedy (R-La.) remained publicly uncommitted on procedural grounds unrelated to the crypto provisions. If the bill clears committee, it must be reconciled with the Senate Agriculture Committee's version (which passed party-line in January 2026), then clear the full Senate at the 60-vote threshold that will require meaningful Democratic support, then reconcile with the House version (H.R. 3633, passed 294-134 in July 2025), and reach the President's desk. Senators Cynthia Lummis (R-Wyo.) and Bernie Moreno (R-Ohio) have both warned that failure to act before Congress's Memorial Day recess on May 21 effectively kills crypto market-structure legislation for the foreseeable future.

For the yield provision specifically: three realistic outcomes. A banking-wins amendment that tightens "solely" and removes balance-and-tenure calibration before the bill moves (the outcome the trade groups are lobbying for). A floor-vote compromise that threads the needle on Senate Democratic support. Or a crypto-wins outcome where the bill passes with Section 404 as drafted and deposit competition dynamics play out as modeled above. The trade groups' formal opposition — and the ABA's mobilization of bank executives in an emergency lobbying campaign the week of May 11 — suggest the banking industry believes the first outcome is still achievable. Polymarket's 62% odds, down from a high of approximately 80% after the initial compromise was announced, suggest real uncertainty about whether the legislative window survives bank pushback at all.

Bottom Line

Bank liability teams should stop analyzing this as a political fight and start modeling it as a funding cost scenario. The structural question is not "will yield-bearing stablecoins outcompete our HYSA?" It is "how much of our price-sensitive transactional deposit base migrates to instruments our cost structure cannot match on yield?" Section 404, in its current form, creates the regulatory architecture for that migration while formally prohibiting the most obvious form of it. What the banking trades are asking for is a tightening of the carve-outs that would otherwise re-permit the prohibited conduct under a different label. If they don't get it before the bill passes, rate competition does not close the cost-structure gap — and that gap is what makes this a different class of problem than previous deposit-substitute competitors.
