$315B in stablecoins sits idle — and banks want to keep it…

Roughly $315 billion in stablecoins now circulates across wallets, exchanges, and corporate treasuries — yet most of it earns nothing. A new analysis argues that crypto's most successful monetary primitive has scaled as money but failed to function as capital, leaving hundreds of billions in digital dollars doing the equivalent of sitting in a checking account.

Why it matters

The critique lands at a politically charged moment. U.S. banking groups have lobbied Congress to block interest, yield, or reward mechanisms on stablecoin balances, and JPMorgan CEO Jamie Dimon recently attacked provisions in the CLARITY Act that would let crypto firms offer interest-like returns without being regulated as banks. Dimon's argument — that any deposit-taking institution should face the same capital and liquidity rules as traditional lenders — signals that stablecoins are no longer a niche product debate. They are a direct threat to core banking economics.

The analysis points to tokenized real-world assets — money market funds, U.S. Treasuries, corporate bonds — as the credible path forward. Tokenized treasuries alone already represent billions in onchain value, but they remain siloed investment products rather than composable dollar primitives. The real prize is a stablecoin that can be held, transferred, and posted as collateral while quietly earning from real underlying assets.

Market impact

If U.S. legislation restricts yield-bearing stablecoins domestically, the model will migrate offshore to jurisdictions with lighter frameworks. That regulatory arbitrage dynamic is the same one that shaped the early Eurodollar market — and it rarely ends with the restrictive jurisdiction winning.
