Ethereum Stablecoin Supply Contracts as USDT and USDC Both Retreat Over 30 Days
Both of Ethereum’s dominant stablecoins shrank in the same month, and that’s the sharpest read of the chain heading into late June 2026. USDT supply on Ethereum fell 3.65% over the 30 days to 2026-06-28, from $82.01B down to $79.02B. USDC ran the same direction over that window, off 3.00% from $49.36B to $47.88B. Two retreats, $2.99B and $1.48B respectively, pulling against the chain at once.
Total USD-pegged stablecoin supply on Ethereum sat at $154.86B as of 2026-06-28. The weight here is hard to overstate: USDT’s $79.02B on Ethereum is 42.67% of all USDT in circulation, against a global total of $185.16B, while USDC’s $47.88B is a heavier 64.81% of all USDC in circulation, against a global $73.87B. When that much of each asset lives on one chain, a contraction on Ethereum stops being a single-network story.
DeFi TVL and DEX Volume Also Pull Back
The stablecoin move lines up with a wider slowdown across Ethereum activity. Total value locked in DeFi on Ethereum dropped 11.51% over the trailing 30 days, from $42.37B to $37.50B as of 2026-06-28. DEX volume cut deeper. Trading on Ethereum decentralized exchanges over the last 24 hours came to $408.72M, a number that marks a 70.82% decline across the same 30-day stretch.
That $408.72M put Ethereum at 9.13% of all on-chain DEX activity over the day, with cross-chain DEX volume totaling $4.47B.
Key Figures at a Glance
- Total USD-pegged stablecoin supply on Ethereum: $154.86B (as of 2026-06-28)
- USDT on Ethereum: $79.02B — down $2.99B (–3.65%) over 30 days; 42.67% of global USDT supply
- USDC on Ethereum: $47.88B — down $1.48B (–3.00%) over 30 days; 64.81% of global USDC supply

Why It Matters
On-chain stablecoin supply works as a proxy for available liquidity, since these assets are the primary medium of exchange and collateral inside DeFi protocols. So read the alignment: a $2.99B USDT decline and a $1.48B USDC decline landing alongside an 11.51% drop in DeFi TVL and a 70.82% drop in DEX volume describe one thing, reduced on-chain engagement showing up across several measures at once. And because Ethereum holds 64.81% of all circulating USDC and 42.67% of all circulating USDT, where its balances go, the broader stablecoin market feels it too.
