BTC drops sharply in 15 minutes by 0.61%: institutional funds continue to net out, triggering short-term selling pressure

From 15:15 to 15:30 (UTC) on June 1, 2026, BTC fell by 0.61% within 15 minutes. The price ranged from 71065.0 to 71533.0 USDT, with a 0.65% amplitude. The price dropped rapidly in the short term, market attention increased noticeably, and volatility intensified.

The main driver behind this move is continued net outflows of institutional funds from Bitcoin ETF products. Based on data, from May 18 to 27, 2026, spot Bitcoin ETFs saw net outflows for 6 consecutive trading days totaling $1.26 billion. In particular, May 27 alone recorded net outflows of $558.6 million, while May 28 recorded net outflows of $410.7 million. Institutional investors reduced BTC holdings via ETF channels, forcing ETFs to reduce spot positions to meet redemptions. This concentrated sell pressure was released within the short-term window, directly triggering the downward price move.

Second, spot ETFs hold about 1.3 million BTC, accounting for 6.5% of circulating supply, and have become a new “quasi-exchange reserve.” When ETFs experience net outflows, these holdings turn into a source of sell pressure, amplifying the pace of selling on top of traditional exchange reserves. Meanwhile, the MVRV Z-Score is close to 1, indicating the market is in a relatively balanced state—neither an extreme bubble nor deeply undervalued—so fund flows have become the core factor driving price. In addition, with institutional capital continuing to flow out, leveraged long positions in the futures market face margin call pressure; some positions are liquidated passively, which further accelerates the price decline.

Risks from market volatility remain. It is necessary to closely monitor whether ETF fund flows continue, changes in on-chain holder/chip structure, and the broader macro financial environment. It is recommended to watch key support and resistance levels and evaluate short-term risk prudently.
