Ethereum Stablecoin Supply Contracts: USDT Down 2.83%, USDC Down 2.72% Over 30 Days

Ethereum Stablecoin Supply Shrinks as USDT and USDC Both Retreat Over 30 Days

The circulating supply of the two largest USD-pegged stablecoins on Ethereum contracted in tandem over the 30 days to June 22, 2026, with USDT falling 2.83% and USDC falling 2.72% — a parallel drawdown that pulled the network’s total stablecoin base to $156.41B. The simultaneous decline across both assets is the sharpest on-chain signal in the current dataset that demand for dollar-denominated liquidity on Ethereum has softened over the period.

USDT on Ethereum

USDT’s circulating supply on Ethereum stood at $79.89B on June 22, 2026, down from $82.22B on May 23, 2026 — a reduction of approximately $2.33B over 30 days. Despite that contraction, Ethereum retains a 42.86% share of all USDT in circulation globally, which totals $186.41B across all chains. That means fewer than half of all USDT tokens currently reside on Ethereum, with the remainder distributed across other networks.

USDC on Ethereum

USDC followed a nearly identical trajectory. Its Ethereum supply declined from $49.58B on May 23, 2026, to $48.23B on June 22, 2026, a drop of roughly $1.35B, or 2.72%. Ethereum’s share of total USDC supply is considerably more concentrated: at $48.23B out of a global total of $74.88B, the network holds 64.41% of all USDC in circulation. That majority share means fluctuations in Ethereum-based USDC have an outsized effect on the asset’s overall supply figures.

DEX Activity Also Pulls Back

The stablecoin contraction coincides with a significant decline in on-chain trading activity. DEX volume on Ethereum was $532.61M over the 24 hours ending June 22, 2026, representing 12.61% of the $4.22B in total on-chain DEX volume recorded globally that day. Over the trailing 30-day window, however, Ethereum DEX volume is down 53.07% — a steeper percentage decline than either stablecoin’s supply reduction over the same period.

TVL Context

Total value locked in DeFi on Ethereum stood at $39.01B as of June 22, 2026. Set against the $156.41B in stablecoin supply on the same network, TVL represents a fraction of the dollar-denominated assets sitting on-chain, indicating that the majority of Ethereum’s stablecoin supply is held outside active DeFi deployment at this snapshot.

Why It Matters

• A concurrent 30-day decline in both USDT and USDC supply on Ethereum signals reduced net demand for dollar liquidity on the network, rather than a shift specific to one issuer.
• Because Ethereum holds 42.86% of all USDT and 64.41% of all USDC, movements in its stablecoin balances carry meaningful weight for each asset’s global supply figures.
• The 53.07% drop in 30-day DEX volume on Ethereum, occurring alongside the stablecoin contraction, points to a broad reduction in on-chain activity during the period rather than an isolated liquidity event.
• With TVL at $39.01B against $156.41B in stablecoin supply, a large portion of Ethereum’s dollar-denominated assets remain outside deployed DeFi positions at the June 22 snapshot.
