Coinbase Stablecoin Yield Ban

1. The OCC has proposed a rule to close a loophole in the GENIUS Act that allows affiliate-paid yield on stablecoins, which could impact Coinbase's $305 million Q1 2026 stablecoin revenue [1]. The proposed rule has sparked a debate between banks and exchanges over deposit outflows and regulatory oversight, with the banking sector warning of massive deposit outflows if the loophole is not closed.

What drove the move

The GENIUS Act was signed in July 2025, and it prohibits payment stablecoin issuers from paying yield on the token [1]. However, the Act does not address affiliate-paid yield, which has created a loophole that Coinbase and other exchanges have exploited. The OCC's proposed rule aims to close this loophole by introducing a rebuttable presumption that any coordinated arrangement between an issuer and an affiliate or related third party to pay holders yield is itself a prohibited yield arrangement [1].

The economics of the loophole are significant, with Circle paying Coinbase $908 million in 2024 as part of their partnership [1]. The payment was larger than Circle's net income, and it has created a platform incentive for Coinbase to hold USDC on its platform. The more USDC sits on Coinbase, the more reserve income Coinbase earns under the agreement [1]. Paying USDC holders a rewards rate just below the Treasury yield Circle earns on reserves keeps the spread intact and pulls coins onto the platform.

The competitive picture

The proposed rule has sparked a debate between banks and exchanges over deposit outflows and regulatory oversight. The banking sector has warned that if the loophole is not closed, it could lead to massive deposit outflows, with a Treasury Department report estimating that stablecoins could lead to as much as $6.6 trillion in deposit outflows [2]. The Bank Policy Institute has urged Congress to tighten stablecoin regulations, arguing that without an explicit prohibition applying to exchanges, the requirements in the GENIUS Act can be easily evaded [2].

What to watch

• The OCC's final rule on the proposed rebuttable presumption, which is expected to be finalized with the presumption substantially intact [1]
• The impact of the proposed rule on Coinbase's stablecoin revenue and USDC balances, with the company likely to challenge the final rule in court [1]
• The response of the banking sector to the proposed rule, with banks potentially seeking to tighten stablecoin regulations further [2]

The proposed rule has significant implications for the crypto industry, with the OCC's interpretation of the GENIUS Act potentially collapsing the distinction between stablecoin issuance and exchange activities [1]. The outcome of the debate will have a significant impact on the future of stablecoins and the regulatory oversight of the crypto industry.
