Between 13:30 and 13:45 (UTC) on 2026-03-28, the ETH spot price fluctuated within the 2002.78 to 2043.89 USDT range, recording a +1.27% return in 15 minutes, with a peak-to-trough amplitude of 2.05%. During this period, market trading activity rose significantly; short-term participants’ attention increased rapidly, and price volatility intensified.
The main drivers behind this unusual move are net inflows into ETFs and continued institutional accumulation. In late March, the daily inflow into ETH-related ETFs reached as high as $175 million, setting a new intra-year high, and directly boosting short-term spot buying pressure. At the same time, some leading institutions, such as Bitmine, accumulated over 1 million ETH in pledged assets in March, which raised on-chain funding demand; with the supply side tightening, this created notable price support. Whale addresses also ramped up their positions sharply at a price level of $2148.7—one single large holder on-chain went all-in long, further amplifying bullish momentum.
In addition, ETH trading volume increased by 15% compared with the previous hour’s average, while the number of active on-chain addresses rose by 10% over the same period, indicating a synchronization between increased market participation and the price anomaly. Data from leveraged trading platforms show the long/short ratio gradually shifted from 49.66%/50.34% to long positions taking the lead; liquidations of shorts accounted for a certain share, magnifying the magnitude of the short-term upward move. On the macro level, the Federal Reserve policy environment has remained stable, crypto-asset regulation has not faced any negative shocks, risk appetite has rebounded, and accelerating capital inflows have triggered a chain reaction.
It should be noted that after short-term capital inflows and leveraged longs increase, if the ETF flows shift away or the long position ratio becomes too high, ETH is prone to a pullback. While whale accumulation can push up the price, if whales reverse positions at any moment, it may amplify subsequent volatility. It is recommended to continuously monitor key indicators such as ETF capital flows, the proportion of leveraged longs, and major on-chain capital inflows and outflows, and to stay alert to the risk of a sudden reversal after a sharp rally in price to obtain more real-time market change information.
