BTC 15-minute sharp drop of 0.51%: Short-term sell-off triggered by rising expectations of Fed rate hikes alongside easing geopolitical risks

On July 28, 2026, 13:30–13:45 (UTC), BTC plummeted 0.51% within 15 minutes. The price fell from about 63,392 USDT to 62,889.7 USDT, with a range of 0.79%. Over the past 24 hours, BTC dropped from a $65,710 high to $62,974, a decline of 4.10%. Market volatility has surged significantly, and short-term risk appetite has rapidly cooled.

The main drivers behind this move are multiple overlapping macro negative factors. On one hand, expectations for Fed rate hikes have sharply warmed: the probability of a rate hike at the July meeting rose to 36.3%, and to 81% for the September meeting. The DXY has also strengthened in tandem, exerting sustained pressure on risk assets. On the other hand, progress in negotiations for a temporary ceasefire agreement across the Strait of Hormuz has temporarily reduced the geopolitical risk premium. Meanwhile, crude oil plunged 6.3%. The market shifted from “safe-haven trading” to “risk repricing,” and BTC, as a risk asset, faced concurrent pressure. Citibank set a short-term gold target price of $4,500 on the condition that “the Fed’s policy turns less hawkish,” but current market expectations are exactly the opposite. This macro backdrop creates significant pressure on risk assets, including BTC.

In addition, extremely thin order book depth has further amplified volatility. The current bid/ask depth ratio is only 0.02, with asks under absolute dominance. At $62,940.8, there is a large sell wall (0.4431 BTC, accounting for 63.4% of the top 5 levels), indicating that with liquidity limited, even a small amount of sell pressure can drive the price sharply lower. Technical signals are also bearish: the 1-hour ADX is 36.67, confirming that the short-term downtrend has strong momentum, and the short-cycle moving average system has turned bearish.

Risks from ongoing volatility remain. Monitor support strength around $62,889 (24h low) and the $62,000 psychological level, while also watching the July 29 Fed rate decision, developments in Strait of Hormuz negotiations, and whether crude oil stabilizes. With order book depth extremely low, the price is highly sensitive to sell pressure. It is recommended to watch the DXY trend and changes in the CME FedWatch rate-hike probability, and to be alert to the risk of further downside probing in the short term.
