BTC 15-minute increase of 0.62%: ETF inflows and liquidity tightening in sync driving spot buying

Between 2026-04-02 13:45 and 2026-04-02 14:00 (UTC), BTC’s return rate within 15 minutes reached +0.62%, with a price range of 65,841.3 to 66,288.3 USDT and a swing of 0.68%. During this period, market activity rose significantly. On-chain data shows the number of active addresses reached 30,953, and on-chain BTC transaction volume surged to 420,690 BTC, drawing widespread attention and increasing market volatility.

The main drivers behind this unusual move are concentrated ETF fund inflows and a sharp drop in exchange reserves. On April 2, the day’s ETF net inflows totaled as much as $458 million, boosting spot demand, while total exchange BTC reserves fell to 2.3 million coins, the lowest level in years. This combination significantly strengthened buy-side pressure; against a backdrop of tightening liquidity, it lifted prices.

In addition, on-chain data confirms that during this time window, user activity and transfer volume rose in sync, reflecting real asset movement and users’ increased entry behavior. In the derivatives market, especially leveraged positions (open interest), rebounded to 88,000 BTC, providing additional momentum for short-term price volatility. At the macro level, global risk-hedging funds flowing into BTC ETFs and an increase in institutional holdings concentration to 6.04% of the total have both amplified the spot price, creating an amplified chain of “funds inflow—liquidity decline—spot buy pressure enhancement.”

Currently, the risk of short-term market volatility has increased. While leveraged capital returning and exchange liquidity tightening have not reached extremes, they still require heightened vigilance. You should closely monitor ETF and exchange fund flows, changes in open interest, and global macro news to guard against sharp adjustments caused by sudden liquidity shifts and market sentiment volatility.
