BTC 15-minute drop of 1.75%: Derivatives liquidity deterioration and capital withdrawals in sync weigh on prices

From 01:30 to 01:45 (UTC) on 2026-04-12, the BTC price experienced significant fluctuations within the USDT 71560.0-73017.1 range. The K-line return recorded -1.75%, and the amplitude reached 2.00%. During this period, market attention increased, the trading atmosphere clearly shifted toward caution, and the intensifying volatility triggered alertness among short-term funds.

The main drivers behind this deviation were the continued deterioration of liquidity in the derivatives market: CME futures open interest fell to a 14-month low, and institutional arbitrage capital accelerated its withdrawal. Futures trading volume trended lower over the long term, and the arbitrage basis narrowed, causing market depth to decline significantly. In an environment where capital follow-through strength weakened, each individual large sell order had a greater impact on price. At the same time, large on-chain funds continued to record net outflows. On April 11, net outflow was -741.99 BTC, and for transfers of over 100,000 dollars, net outflow was -819.82 BTC, indicating that some large holders continued to reduce positions on rallies, and spot buy-side support weakened significantly.

In addition, spot ETF net inflows have seen marginal deceleration since early April, gradually weakening the support effect of new capital on spot prices. Meanwhile, on-chain activity and transaction fees fell to historical lows, and overall market trading willingness was insufficient. Liquidity depletion amplified the negative feedback of one-way trading. After BTC’s weekly rally of as much as 9% in the BTC week period, some short-term funds chose to realize gains at a stage high, adding short-term selling pressure. With multiple factors converging, short-term volatility was significantly amplified.

At present, the risk of short-term BTC volatility is rising. Going forward, it is important to focus on the continued net outflow of on-chain funds, ETF subscription and redemption dynamics, and the further evolution of futures positioning and liquidity. If the capital outflow and liquidity deterioration trend intensifies, spot price volatility risk may move higher. Investors are advised to closely monitor the distribution of key price levels, on-chain behavior, and the macro news backdrop, and to obtain real-time market information promptly.
