The world's two largest economies are racing to dominate digital money. One just took the lead.

China's digital yuan started paying interest to holders. Meanwhile, US lawmakers are debating whether to ban American stablecoins from doing the same thing. If this sounds backwards, that's because it is.

Coinbase's Chief Policy Officer Faryar Shirzad put it bluntly: the US risks "handing our global rivals a big assist" in the race for digital currency dominance.

China's Digital Yuan Just Got a Major Upgrade

The People's Bank of China announced that commercial banks can now pay interest on digital yuan (e-CNY) wallets under a new framework that went live today. This isn't a minor tweak. PBOC Deputy Governor Lu Lei described it as a shift from "digital cash" to "digital deposit currency"—essentially upgrading the e-CNY from a payment tool into a savings instrument.

The Numbers Behind China's CBDC

Adoption is growing with 3.48 billion transactions, 16.7 trillion yuan (~$2.34 trillion) in cumulative volume, and over 230 million personal wallets active in the ecosystem.

Despite these impressive figures, the digital yuan has struggled to compete with Alipay and WeChat Pay, which control over 90% of China's mobile payments. Interest payments are Beijing's answer to the adoption problem—giving users an actual reason to hold e-CNY instead of just passing it through.

The US Is Moving in the Opposite Direction

While China incentivizes digital currency adoption, the US is having a different debate entirely. The GENIUS Act, signed into law by President Trump in July 2025, established America's first federal stablecoin framework. It included a provision that bars stablecoin issuers like Circle (USDC) and Tether (USDT) from paying interest directly to holders.

The diverging regulatory paths of the world's two largest economies could determine future dominance.

The law does allow third-party platforms—like Coinbase—to offer rewards on stablecoins. But now, that "loophole" is under attack. The American Bankers Association wants Congress to expand the interest ban to cover platforms too, arguing it threatens traditional bank deposits.

Why Banks Want Stablecoin Yields Dead

The banking industry's argument boils down to deposit protection. If stablecoins can offer competitive yields through platforms, money might flow out of traditional bank accounts. However, the crypto coalition disputes this logic, citing studies showing no disproportionate deposit outflows tied to stablecoin adoption.

Opposition to stablecoin rewards reflects protection of incumbent revenue models, not safety.

Critics argue the real issue is competition. With average checking account yields at 0.07%, stablecoin reward programs offer significantly higher returns that banks are hesitant to match.

The Geopolitical Stakes

This isn't just a regulatory squabble—it's a contest for the future of money. Three different approaches are emerging:

  • China: State-controlled CBDC paying interest (as of Jan 1, 2026).
  • US: Private stablecoins with yield currently under debate.
  • Europe: CBDC explicitly banned from paying interest.

China is betting that an interest-bearing CBDC can drive adoption while coexisting with its banking system. The US, meanwhile, banned federal CBDC development entirely while simultaneously restricting what private stablecoins can offer.

The Bottom Line

China just made its digital currency more attractive to hold. The US is debating whether to make its stablecoins less attractive. In a race where network effects and adoption momentum matter, that difference could define which currency settles the world's transactions in 2030.
