Coin Metrics study finds USDC and USDT supply growth respond differently to crypto market returns

Coin Metrics research shows USDC growth slows after strong crypto returns while USDT growth accelerates, complicating stablecoin supply as a Bitcoin demand signal.

Why it matters

The research challenges the common practice of using combined stablecoin supply as a proxy for Bitcoin buying pressure, showing issuer composition matters and supply growth reflects varied demand types beyond spot accumulation.

Key facts

What happened

CryptoSlate reported on a Coin Metrics study published October 20 that analyzed four years of weekly data to test six drivers of USDC and USDT supply growth. The study found that stronger non-stablecoin crypto market returns in one week correlated with slower USDC growth the following week but faster USDT growth. A lending-yield association was specific to USDC. No model explained more than 25% of weekly supply variation. The findings suggest aggregate stablecoin issuance should not be treated as a single pool of cash waiting to buy Bitcoin, since tokens can serve lending, collateral, or payment demand before reaching spot markets.
