A substitute text advanced by the U.S. Senate Banking Committee would prohibit payment stablecoin issuers from offering interest or yield “solely for holding” the tokens. Activity-based incentives — rewards tied to actual transactions, loyalty programs, or platform use — would remain permitted under the proposed carveouts. The change sits inside broader crypto market structure legislation still moving through Congress.

Context: stablecoins as savings and rails in Latin America

Stablecoins have become everyday infrastructure across much of Latin America. In high-inflation or currency-volatile economies, individuals and businesses use USDT, USDC and similar dollar-pegged tokens to preserve value, pay suppliers, receive remittances, and settle cross-border invoices without waiting on traditional banking rails or absorbing FX spreads.

Recent platform data and regional reporting show stablecoins often accounting for the majority of crypto flows in countries like Argentina and Brazil. Holding the tokens is not just a trading position for many participants — it functions as a practical dollar savings or working-capital vehicle when local options are costly or restricted.

Some exchanges and fintechs have layered on holding rewards or yield programs as a customer-acquisition and retention feature. The pitch is straightforward: keep your dollars in the stablecoin on our platform and earn a small return on top of the peg protection.

The draft language and what it actually changes

The Senate Banking substitute (part of the multi-committee effort to advance a version of market structure rules alongside the House-passed CLARITY Act framework) rewrites the stablecoin yield section as a prohibition. Issuers and intermediaries generally may not pay interest or yield on a payment stablecoin balance when the payment is made simply because the user is holding the token.

The text includes an “economically or functionally equivalent” test aimed at arrangements that look like bank deposit interest in practice. Carveouts are expected for rewards linked to specific user actions — sending a payment, participating in a rewards program tied to volume or other behaviors, or other non-holding triggers. The precise scope of those carveouts will be shaped in further rulemaking involving Treasury, the SEC, and the CFTC, with civil penalties on the table for violations.

This is not a blanket ban on all promotions. It is a deliberate line-drawing exercise between “holding yield” (which banks argue competes directly with insured deposits) and “usage incentives” (which the crypto side says are product features, not interest).

The provision reflects months of negotiation. Earlier drafts preserved more permissive language on rewards; the current substitute tilts toward the prohibition-plus-carveouts approach after pushback from traditional banking interests concerned about deposit flight.

Why Latin America cares

Latin American users and the platforms that serve them are not the direct targets of U.S. banking-committee drafting. But they are major consumers of the products the rules will shape.

When a platform popular in Mexico, Colombia, Argentina or Brazil currently advertises a yield or bonus for simply keeping USDC or another stablecoin in an account, that feature sits squarely in the “solely for holding” bucket the draft targets. If the final law and rules close that lane, platforms will have to re-engineer incentives around spending, trading, or other on-platform activity — or drop the reward altogether.

For a user in Argentina using stablecoins to protect monthly income from peso devaluation, a few percent of holding yield is material. For a small business in Mexico managing cross-border supplier payments, the difference between a plain stablecoin balance and one that quietly accrues a reward can influence where liquidity sits. Remittance recipients who leave funds parked briefly before converting to local currency feel it too.

The rules will not stop stablecoin usage in the region. They may, however, change the ancillary economics that platforms use to compete for that usage. Conversations at this week’s Stablecoin Conference LATAM in Mexico City are already focused on compliance, reserves, and distribution; the U.S. legislative details on yield add another variable for issuers and local partners planning product roadmaps.

Self-custody holders who move coins off-platform to their own wallets are less directly affected by platform-specific reward programs, but the overall supply of “sticky” on-platform liquidity and the marketing messages that accompany it will adjust.

Takeaway

U.S. legislative text is beginning to define the exact shape of stablecoin features that flow downstream to Latin American users through the apps and exchanges they actually use. The distinction between holding-based yield and activity-based rewards is technical on paper but practical in the region where stablecoins serve real treasury and savings needs.

For users, the core value of a well-reserved, liquid dollar stablecoin remains the peg and the ability to move value quickly and cheaply. Any rewards layered on top are a bonus that platforms may need to tie more explicitly to usage if this language becomes law. Track the reconciliation process between Senate and House versions, and the subsequent rulemaking — those details will determine what incentives survive for regional participants.

Not financial advice. Stablecoins carry issuer, reserve, regulatory, peg, and operational risks. Rewards and yield programs are subject to change and are not guaranteed. Users should review the specific terms, reserve attestations, and legal status of any token and platform they use. Legislative text can evolve before enactment.
