Stablecoins have become crypto's most successful application, serving as the dollar layer for trading, collateral, and payments. However, with roughly $315 billion in circulation, most stablecoins remain idle as digital cash, not productive capital. In traditional finance, idle cash is minimized through money market funds and credit markets, but crypto has yet to achieve similar capital efficiency. Attempts at crypto-native yield, such as staking and liquidity mining, were largely circular and dependent on token emissions rather than real economic activity. The next evolution involves connecting onchain dollars to real-world assets (RWAs) like treasuries, corporate bonds, and credit. Tokenized treasuries have already gained billions in value, but the true opportunity is a stablecoin that earns yield from underlying real assets while remaining usable across crypto. This shift has sparked policy debates in the U.S., where banking groups seek to restrict interest on stablecoin balances, viewing them as competitors to bank deposits. The question is whether digital dollars will remain passive cash equivalents or evolve into productive capital. If U.S. law blocks this model, other jurisdictions may lead the way.

Key facts

• $315 billion in stablecoins mostly idle as digital cash, not productive capital.
• Crypto-native yield was circular, dependent on token emissions and inflows.
• Next step: connect onchain dollars to real assets like treasuries and bonds.
• U.S. banking groups push to restrict interest on stablecoin balances.
• Stablecoins increasingly viewed as competitors to core banking products.
