ETH 15-minute short-term pullback of 0.77%: The stronger U.S. dollar and earlier profit-taking converge

From 13:30 to 13:45 (UTC) on July 28, 2026, ETH saw a short-term dip of 0.77% within 15 minutes. The price range was 1860.69 to 1887.23 USDT, with an amplification of 1.41%. Prior to that, over the previous 24 hours, ETH fell from the $1977 high by about 3.38% to around $1890, with relatively low trading volume and limited market participation—showing the characteristics of a low-volatility technical pullback.

The main driver of this move is the pressure effect on risk assets in a strengthening Dollar environment. The DXY (Dollar Index) hit a one-month high, and hotter expectations for the Fed to raise rates created clear downside pressure on alternative investments such as ETH. Meanwhile, after the market rallied to the $1977 high, it lacked sustained positive catalysts. Profit-taking concentrated, and selling pressure built up, leading to a rapid short-term pullback.

In addition, Bitmine Immersion at the institutional level added nearly 10,000 ETH (about $19.4 million), which does bring some incremental allocation demand, but its relevance_score is only 0.36—leaving limited direct impetus for price. It’s more like background noise. Order Book data shows a bid/ask depth ratio of 7.76, with bids clearly in the lead. Below $1890, there is a large buy-wall support, indicating strong downside follow-through. Technically, the 15-minute MA has turned bearish, but the daily and 4-hour levels still maintain a bullish trend, suggesting this drop is a normal pullback within the broader medium-term uptrend.

Volatility risk remains, so it’s important to watch whether the $1866 support holds. A breakdown could trigger further pullback. Going forward, key focus should be on changes in Fed policy signals, the DXY trend, the BTC linkage/correlation effect, and changes in trading volume. In terms of execution, traders should stay alert to short-term volatility risk; near support, it may be prudent to wait for confirmation of a rebound after observing a volume-expansion signal before taking positions.
