BTC 15-minute rise of 0.56%: Derivatives short liquidations and active large orders resonating to drive gains

On March 20, 2026, from 07:30 to 07:45 (UTC), Bitcoin experienced a sudden price movement. The 15-minute return was +0.56%, with the price ranging from 70,423.0 to 70,854.2 USDT, and an amplitude of 0.61%. Market attention increased during this period, and short-term volatility slightly intensified, driven by the combined effects of spot and derivatives markets, which increased buying pressure.

The main driver of this movement was the leverage structure in the derivatives market—concentrated short positions with low funding rates, continuous growth in open interest (OI) of Bitcoin futures, and increased active buying. During the rapid price rise, some short positions were forcibly liquidated (short squeeze). On-chain data shows approximately $270 million in short positions were liquidated during this window, creating a chain reaction that pushed prices higher and amplified the rally.

Additionally, large orders (single orders exceeding 100 BTC) appeared frequently on a major exchange, with active buy orders accounting for 51%, indicating institutional or whale-driven efforts to push spot and derivatives prices higher in sync. On-chain fund flow data shows Bitcoin inflows to spot exchanges at 2.5 times the baseline, while stablecoin inflows remained unchanged, suggesting that selling pressure from U.S. investors has eased, and spot market sentiment remains cautious. The main driving force appears to be the derivatives market. During periods of lower liquidity on major platforms, large traders further amplified the price movement.

Currently, short-term leverage and liquidity risks coexist. If Bitcoin retraces, there is a risk of forced liquidation of long leveraged positions. Key support levels around 70,000 USDT should be monitored, along with the leverage structure in derivatives and on-chain fund outflows. Market liquidity is concentrated on leading platforms; ongoing monitoring of capital flows, macro events, and changes in derivatives leverage is essential to gain more insights into potential market anomalies.
