Coinage Morning Brief: Stablecoin Supply Extends Its Climb as Risk Appetite Returns

Aggregate stablecoin supply extended a months-long climb overnight, a quiet but important signal that dry powder on-chain is still expanding even while spot prices stay range-bound.

What happened

Combined USDT and USDC supply grew for a sixth straight week, continuing a rally that has added tens of billions of dollars in stablecoin float since mid-2025, per CoinMarketCap and issuer attestations. Bitcoin traded in a roughly two-percent band on the day while ETH outperformed by a narrow margin. On-chain DEX volumes ran hot for a third straight session, concentrated on Solana and Base, where stablecoin-denominated trading pairs have captured a growing share of activity.

What it means

Stablecoin supply is one of the least romantic but most reliable on-chain indicators, precisely because it’s fully observable and hard to fake: every dollar of supply corresponds to a token that exists on-chain and can be independently counted. When it grows during a price consolidation, it usually means new capital is being staged rather than deployed. Pair that with rising DEX volume concentrated on a couple of chains, and you have a setup that has historically preceded a pickup in mid-cap token participation, though the correlation isn’t guaranteed. The risk is that any macro surprise, a hot PPI print or a hawkish comment from a central banker, sends that dry powder back to the sidelines rather than into risk assets.
