USD-Pegged Stablecoins on Ethereum Decline to $156.72B, USDT and USDC Both Down

Ethereum’s USD-Pegged Stablecoin Supply Contracts to $156.72B as USDT and USDC Both Retreat Over 30 Days

The total circulating supply of USD-pegged stablecoins on Ethereum stood at $156.72B as of June 17, 2026, with the two dominant tokens — USDT and USDC — both posting declines over the preceding 30-day period. The simultaneous contraction across the two largest stablecoins on the network marks a meaningful shift in on-chain dollar liquidity, set against a broader Ethereum DeFi ecosystem carrying $39.27B in total value locked (TVL).

USDT: Ethereum Supply Falls $2.61B in 30 Days

USDT circulating supply on Ethereum declined 3.14% over the 30 days to June 17, 2026, moving from $82.96B on May 18, 2026 to $80.35B. The $2.61B reduction represents a contraction in the Ethereum-based portion of the token’s global footprint. Despite the decline, Ethereum continues to host a substantial share of total USDT supply: the $80.35B on-chain balance accounts for 43.06% of the $186.59B in total USDT circulation across all networks as of June 17, 2026.

USDC: Steeper 30-Day Decline at 4.73%

USDC recorded a sharper pullback over the same period. Supply on Ethereum fell 4.73%, from $50.66B on May 18, 2026 to $48.27B on June 17, 2026 — a reduction of approximately $2.39B. Ethereum’s share of total USDC in circulation stands at 64.43%, with the $48.27B Ethereum balance drawn from a global supply of $74.91B. That chain-share figure underscores how concentrated USDC remains on Ethereum relative to USDT’s more distributed cross-chain presence.

Stablecoin Supply in Context of Ethereum DeFi

Taken together, USDT and USDC account for the dominant portion of the $156.72B total USD-pegged stablecoin supply on Ethereum, with USDT’s $80.35B and USDC’s $48.27B combining for $128.62B of that figure. Ethereum’s DeFi TVL of $39.27B sits alongside — but is distinct from — the stablecoin supply figure, which measures circulating balances rather than assets actively deployed in lending, liquidity, or other DeFi protocols.

The difference in 30-day decline rates between the two tokens — USDC falling at 4.73% versus USDT at 3.14% — means USDC contracted at a faster pace on Ethereum over the measured window, even as USDC’s chain-share of its own global supply (64.43%) remains notably higher than USDT’s equivalent (43.06%).

Why It Matters

• A combined decline of roughly $5B in USDT and USDC supply on Ethereum over 30 days signals a reduction in on-chain dollar liquidity available to the network’s DeFi ecosystem, which holds $39.27B in TVL.
• USDC’s higher Ethereum chain-share (64.43%) means movements in Ethereum-based USDC supply have an outsized effect on its global circulating total compared with USDT, which is more evenly spread across chains at a 43.06% Ethereum share.
• The total USD-pegged stablecoin figure of $156.72B on Ethereum provides a reference point for tracking how dollar-denominated on-chain liquidity on the network evolves over time.
