BTC drops 0.33% over 15 minutes: ETF net outflows and derivatives deleveraging resonate, triggering short-term selling pressure

From 00:30 to 00:45 (UTC) on May 26, 2026, BTC recorded a -0.33% drop within 15 minutes. The price fell from 77193.4 USDT to 76834.1 USDT, with a swing of 0.47%. The market is in a consolidation pattern. The intraday price fluctuation range for the day was $76,019.89 to $77,770.64, with a swing of about 2.3%. This unusual movement falls within the normal intraday volatility range.

The key driver behind this move is ongoing net outflows of institutional funds. On May 26, US spot ETFs showed a net outflow, with a single-day net outflow of -$105.2M (IBIT -$68.9M, FBTC -$36.3M). Over six consecutive trading days, cumulative net outflows totaled $1.26B to $1.55B. In 2026 year-to-date terms, net inflows have compressed sharply from a significantly positive value at the beginning of the year to only $536M, indicating a substantive reversal in institutional demand.

At the same time, the derivatives market is accelerating deleveraging. Open interest fell by 1.41% versus the previous day (-$777.95M), and over the past 30 days it dropped by 4.72%, or about -$2.69B. Notably, within the past 24 hours, the long liquidation share reached 100%, totaling $309.13M. This suggests that previously overextended long positions are being forcibly closed, directly turning into selling pressure. In addition, whale selling continues: addresses holding 1,000-10,000 BTC reduced their holdings by about 220,000 BTC over the past year—the steepest reduction since early 2023. However, Value Days Destroyed remains low, indicating that long-term holders are not panicking and that this is an orderly rotation.

Technically, the price is oscillating in a range between key support at $76,087 and resistance at $78,152. The Fear and Greed Index remains at a relatively cautious level of 29. Risks from accelerated ETF outflows should be closely watched. If the institutional net outflow trend continues, it may test the $76,000-$76,500 support zone. Although derivatives open interest has already declined, it is still around the $54B level; extreme volatility could trigger cascading liquidations. It is recommended to monitor ETF fund flows, changes in open interest, and the effectiveness of the $76,087 support level.
