Ethereum’s available supply on major centralized exchanges has dropped by approximately 18% since early June, falling from 7.69 million ETH to 6.28 million ETH. Data from Santiment shows an additional 275,000 ETH left trading platforms after August 19 alone, marking the lowest exchange balance recorded during the measured period.
The outflows accelerated even as ETH’s price climbed around 27% since August 16 to reach $2,528, defying the typical behavior where traders move coins to exchanges to take profits during rallies. Instead, large holders appear to be shifting assets into self-custody and staking protocols, with more than 35% of the ETH supply now staked on the network.
By contrast, Bitcoin exchange reserves rose by 0.25% over the same timeframe, remaining near the upper end of their recent range. Analysts note that Bitcoin holders often keep assets on exchanges for rapid trading, while Ethereum investors can generate native yield through staking, reducing the incentive to leave coins idle on trading platforms.
The decline in exchange-held ETH is widely viewed as a bullish signal because it lowers the pool of tokens immediately available for sale, potentially easing sell pressure. However, Santiment’s figures are a snapshot and can be influenced by custody practices, staking activity and DeFi participation. Technical analysis cited by TradingView suggests ETH remains within a broad consolidation, with resistance in the $2,497–$2,585 range, and buyers need to secure a firm close above $2,600 to break the bearish trend.
While lower exchange balances do not guarantee price appreciation, the sustained outflows since June suggest a meaningful shift toward long-term holding among Ethereum investors.
