Stablecoin Supply Is Falling, Yet Stablecoin Usage Just Hit a Record

The stablecoin market is producing one of the strangest divergences in crypto right now. Total stablecoin market capitalization has fallen by roughly $10 billion from its May peak, with the market sitting around the $300 billion level.

Yet stablecoin usage is moving in the opposite direction.

Visa's Allium-powered data recorded $1.79 trillion in adjusted stablecoin transaction volume in June, a record monthly figure. That represented a 63% increase from May's $1.1 trillion and was 125% higher than June 2025.

So the market is shrinking by supply while growing by activity.

That's important because stablecoin supply has traditionally been treated as a convenient proxy for crypto adoption. More stablecoins meant more dollars sitting on-chain and potentially more capital available for trading, DeFi and payments.

But the latest data suggests that assumption may be becoming outdated.

A smaller pool of stablecoins can potentially circulate more rapidly instead of simply sitting idle.

June's numbers illustrate this clearly: the market had less stablecoin capital than at its May peak, yet that capital was being transferred at a record pace. USDC was particularly active, accounting for roughly $1.21 trillion of the adjusted June volume, compared with approximately $576 billion for USDT in the cited dataset.

That creates a new metric worth watching.

Instead of asking only "How much stablecoin supply exists?", investors may increasingly need to ask "How frequently is that supply actually being used?"

If this divergence persists, stablecoin velocity could become a more meaningful adoption indicator than market capitalization alone.
