BTC 15-minute increase of 0.86%: Short covering and ETF capital inflows resonate to drive the rebound

2026-04-13 13:45 to 2026-04-13 14:00 (UTC), BTC price fluctuated within the range of 70,945.9 to 71,699.9 USDT, recording a significant 0.86% rise within 15 minutes, with an amplitude of 1.06%.
Market attention surged, short-term volatility intensified, large on-chain transfers and spot and derivatives trading volumes expanded simultaneously, indicating that major capital activity was at its highest level of the year.
The main driver of this movement was the large leveraged short positions probing the 72,000–73,500 USDT range, creating a local liquidity vacuum, causing some shorts to be involuntarily liquidated, and the price quickly moved upward in a short period.
Meanwhile, institutional funds, represented by Morgan Stanley, continued to flow into the market through ETFs, with the first bank-issued spot BTC ETF in early April achieving a daily net inflow of $34 million, significantly boosting spot demand, suppressing short structures, and providing a capital base and emotional support for this rally.
Additionally, influenced by positive factors such as the easing of oil prices driven by the US-Iran ceasefire and the upcoming passage of the US CLARITY Act, global risk appetite marginally increased, further attracting institutional capital into BTC, forming a macro liquidity, regulatory expectation, and technical structure resonance.
On the technical side, repeated testing of the upper boundary of the long-term BTC range and expanding spot demand jointly supported short-term price elasticity.
High leverage structures and unliquidated short positions in key ranges still pose short-term correction risks; if spot buying weakens or macro liquidity tightens, the price may decline, and longs could face involuntary liquidations.
It is recommended to continuously monitor the changes in long and short positions above 72,000 USDT, institutional ETF subscription trends, and the Federal Reserve’s late-April policy meeting, adjusting tracking of on-chain capital flows, market sentiment, and policy signals in a timely manner.
