The stablecoin market has added $2 billion in value over the past week, pushing total capitalization to $322.74 billion, according to Defillama data. The sector, which had been hovering just above the $320 billion mark for some time, is now sitting at a fresh high.
Tether still dominates the field
Tether, the largest stablecoin by market cap, continues to hold its commanding position. USDT's market capitalization remains near $190 billion, giving it the biggest share of the stablecoin sector by a wide margin. That dominance hasn't budged much even as other stablecoins have seen their own growth spurts.
A slow climb above $320 billion
Before this latest weekly gain, the stablecoin market had been stuck in a narrow range slightly above $320 billion for several weeks. The $2 billion injection pushed it decisively past that threshold. It's a modest increase in percentage terms — roughly 0.6% — but in dollar terms it represents real demand for dollar-pegged digital assets.
Stablecoins are used across crypto exchanges, decentralized finance protocols, and increasingly for cross-border payments. Their combined market cap is often read as a proxy for liquidity flowing into the broader crypto ecosystem.
No single event or announcement appears to have triggered the latest jump. The rise came across multiple tokens, with Tether's share holding steady. That suggests organic market activity rather than a one-off large issuance.
Whether the sector can sustain this level — or climb higher — will depend on where the next wave of demand comes from. For now, the numbers are heading in one direction.
