China’s Interest-Bearing Digital Yuan Ramps Up Pressure on U.S. Stablecoin Rules

China’s decision to allow banks to pay interest on digital yuan wallets from Jan. 1 is emerging as a pointed challenge to U.S. stablecoin policy, exposing a growing divergence between Beijing’s state-backed digital currency strategy and Washington’s restrictions under the GENIUS Act.

The move enables China’s commercial banks to treat e-CNY balances more like traditional deposits, integrating the central bank digital currency directly into their balance-sheet operations. By contrast, U.S. dollar stablecoins remain barred from offering any form of yield, even when backed by interest-earning reserves.

Coinbase CEO Brian Armstrong had recently warned X post that the policy shift gives China a “competitive advantage,” arguing it could have a “big impact on whether U.S. stablecoins are competitive.” His comments reflect mounting concern across the crypto industry that Washington’s approach may be inadvertently weakening the dollar’s position in the digital economy.

Armstrong’s warning builds on months of lobbying in 2025, during which he urged lawmakers to allow regulated stablecoin issuers to pass through yield to users. The GENIUS Act, signed into law in July 2025, created the first federal framework for dollar-pegged stablecoins — but explicitly prohibited issuers from paying interest or rewards.

China’s timing has sharpened the contrast. While U.S. regulators frame yield bans as necessary to protect financial stability, Beijing is positioning its digital yuan as a competitive, interest-bearing alternative capable of functioning both as money and a savings instrument. The result is an increasingly visible policy gap between the world’s two largest economies.

The U.S. deposit dilemma

At the heart of the U.S. debate is a structural conflict between innovation and bank protection. Commercial banks have pushed aggressively to widen the GENIUS Act’s yield ban to third-party platforms, warning that interest-bearing stablecoins could siphon deposits away from traditional lenders, particularly smaller institutions.

Crypto executives counter that blocking yield entrenches incumbents while undermining the dollar’s global appeal. In a world where capital is increasingly mobile and digital, preventing stablecoins from sharing interest earned on Treasury bills or cash equivalents risks pushing users — and liquidity — toward alternatives, including China’s e-CNY.

Some industry leaders warn that this dynamic could ultimately weaken the dollar’s role in digital payments and cross-border commerce, especially if foreign users gravitate toward yield-bearing digital currencies that offer both stability and return.

The policy standoff is unfolding alongside a shifting macro environment. Ron Tarter, CEO of U.S. dollar-backed stablecoin issuer MNEE, suggested that a potentially weaker dollar in 2026 could prompt lawmakers to rethink the strategic value of compliant stablecoins as tools for preserving dollar dominance in global trade.

Meanwhile, Reeve Collins, cofounder of Tether and chairman of STBL, noted that stablecoins have evolved beyond simple payment rails. As inflation concerns persist, users increasingly expect digital dollars to preserve purchasing power, driving interest in real-world asset-backed models and structures that share yield with holders rather than concentrating returns with issuers or banks.

Midterms and enforcement risk

Looking ahead to the 2026 midterms, regulatory uncertainty remains a key overhang. Winston & Strawn partner Drew Hinkes said an outright repeal of the GENIUS Act is unlikely, but warned that a shift in congressional control could stall broader market-structure legislation and reshape enforcement priorities at agencies such as the SEC and CFTC.

For stablecoin issuers, the message is clear: operate as if the current rules are here to stay, while preparing for stricter scrutiny just as China accelerates its digital yuan rollout.

As Beijing advances an interest-bearing CBDC and pushes it deeper into global payments infrastructure, U.S. policymakers face a narrowing window to decide whether protecting bank deposits is worth the risk of ceding ground in the race for digital money dominance — or whether controlled, regulated yield could be the key to keeping dollar-based stablecoins competitive on the world stage.
