ETH short-term 15-minute rally of 0.87%: institutional large-scale accumulation combined with exchange net outflows boosting the price

On April 22, 2026, from 02:15 to 02:30 (UTC), ETH experienced a rapid surge within 15 minutes, with a return of +0.87%, a price range of 2334.9 to 2357.0 USDT, and an amplitude of 0.95%, indicating a significant increase in market volatility.

The main driving force behind this movement was a substantial outflow of on-chain funds from exchanges combined with continued institutional accumulation. Data shows that ETH’s net exchange flow for the month was -164,873.93 ETH, with large transactions (>$1M) net outflows exceeding 174k ETH, indicating that institutions and large holders are transferring assets to on-chain wallets or DeFi protocols to reduce selling pressure on exchanges. Simultaneously, Bitmine institutions purchased 101,627 ETH in a single day, with total holdings reaching 4.24 million ETH (worth approximately $12.33 billion), directly pushing the price upward.

Additionally, the expansion of the ETH ecosystem resonated with macroeconomic conditions. In 2026, DeFi and NFT applications continued to grow, institutional adoption increased, and following the U.S. SEC approval of ETH spot ETFs, institutional funds kept flowing in, boosting long-term market confidence. Total on-chain transfer volume reached 2.01 million ETH, with high fund activity, but there were no signs of extreme liquidations or abnormal funding rates in the derivatives market, indicating that this movement was mainly driven by spot on-chain fund flows.

Regarding risks, large net outflows from exchanges suggest tightening market liquidity. If large holders sell off en masse later, prices could face a correction. It is important to monitor on-chain whale account holdings, changes in exchange net flows, and macro policy developments. Short-term investors should be cautious of volatility risks, with support levels around 2300 USDT and resistance at 2400 USDT.
