BTC 15-minute increase of 0.48%: ETF capital inflows and leveraged short liquidations jointly drive price fluctuations

On April 13, 2026, from 14:30 to 14:45 (UTC), the spot price range of BTC was between 71,600.7 and 71,997.0 USDT, with an amplitude of 0.55%. During this time window, the return reached +0.48%, market volatility intensified, trading volume and attention increased simultaneously, marking a significant change under the recent institutional-led market trend.

The main driving forces behind this anomaly are the continuous net inflow of ETF funds and the concentrated release of institutional buying. Data shows that large ETF inflows have recently begun, with a cumulative net inflow of over $5.3 billion since April, significantly boosting spot market demand. Large institutional buy orders absorbed market supply, creating price support amid liquidity tightness, and temporarily drove BTC prices higher.

Additionally, short positions in the leveraged derivatives market concentrated around key price levels, triggering some forced liquidations around 14:45. Latest on-chain data indicates that daily liquidations of shorts reached $427 million, with leveraged short positions stacking above 73,500 USDT. Coupled with whale addresses increasing their holdings and rising active addresses, funds are flowing into risk assets. From a macro perspective, easing expectations of Federal Reserve rate hikes and weakening geopolitical risks have increased market risk appetite, with multiple resonance effects amplifying short-term volatility.

In terms of short-term risks, BTC reserves on exchanges have fallen below 2.3 million coins, further tightening liquidity. If subsequent capital inflows slow down or institutional withdrawals occur, the market may face sudden pressure. Key factors to monitor include ETF inflow scale, on-chain fund flows, and derivatives leverage position changes. Users should be alert to sharp volatility caused by concentrated high-leverage shorts and underlying liquidity risks, and continuously watch key resistance levels and on-chain indicators.
