Stablecoin supply pushed to a record above $323 billion this quarter just as the share of staked Ether reached its own peak near 30%.
Stablecoin Supply Tops $323B
The total value of all stablecoins climbed past $323 billion in mid-May, a fresh all-time high confirmed by CoinGecko data. Supply reached $323.3 billion before easing slightly.
Tether (USDT) drove most of that growth, expanding its supply by roughly $5 billion over the past month and holding 58.69% of the market.
The headline number hides a slowdown, though. USD Coin (USDC), Ethena USDe and PayPal USD together shed about $4.2 billion in combined supply, with Ethena USDe alone falling 28% in a month.
Meanwhile, the amount of Ether (ETH) locked in staking contracts has stayed near a record. More than 36 million ETH now sits staked, close to 30% of circulating supply, after the staked ratio first cleared that mark earlier this year.

The Q2 Correlation Analysts Watch
Traders treat stablecoin supply as a proxy for capital waiting on the sidelines. A larger pool signals more dry powder ready to rotate into Bitcoin (BTC), Ether or altcoins once sentiment turns.
That reading carries a caveat.
Rising stablecoin supply does not automatically lift crypto prices, since stablecoins can also grow on hedging demand, staking activity or plain payment use. With the Fear & Greed Index parked in "Fear" territory, analysts see liquidity building rather than chasing risk.
The staking side tells a parallel story. Heavy participation pulls Ether off exchanges, and that thinner liquid supply can amplify price moves in either direction when demand shifts during the quarter ahead.
Why ETH Staking Keeps Climbing
Institutional money explains much of the staking surge. Treasury firms and exchange-traded products have steadily added validators, and BitMine alone has staked more than 1.25 million ETH while building a multi-million-token position.
Validator exit queues have stayed near historic lows, easing concerns about sudden unstaking pressure.
Ether staking has grown for years even when prices lagged. The staked total topped 34 million ETH in mid-2025 and crossed 36 million by January 2026, a roughly 77% rise over two years that tracked institutional accumulation far more closely than ETH's own price chart.
