BTC 15-minute short-term rally of 0.60%: Active buying pressure combined with liquidity contraction driving the price upward

From 02:00 to 02:15 (UTC) on May 25, 2026, the BTC price return was +0.60%, with the price rising from 76,937.3 USDT to 77,487.0 USDT, an amplitude of 0.71%. During this period, the market experienced a noticeable anomaly, with buy orders accounting for approximately 73% and sell orders about 64%, and the order book showing a short-term strong buying pattern.

The main driver of this anomaly was the concentrated entry of active buy orders. Order book data indicates that within 15 minutes, the proportion of buy orders significantly exceeded that of sell orders, with medium-sized buy orders densely appearing, and funds showing a pattern of phased entry rather than a single large purchase by one institution. Volatility indicators did not show abnormal amplification, suggesting that the price increase was driven by healthy buying activity, not panic chasing.

Meanwhile, on-chain data shows multiple factors resonating. The net inflow to exchanges dropped sharply from about $420k ten minutes ago to approximately $420k, indicating a significant decrease in funds flowing into exchanges, with no large-scale selling pressure in the market. More notably, in the past 24 hours, BTC balances on exchanges decreased by about 7%, indicating investors are shifting BTC out of exchanges into on-chain holdings. The overall market liquidity contraction further amplified the buying pressure on prices. Additionally, net inflows into the BTC spot ETF in the US stock market showed no anomalies, and traditional financial channels did not impact the spot market.

Regarding risks, attention should be paid to volatility amplification under tightening liquidity. The continuous decline in exchange balances means less liquidity available for selling, which could exacerbate price pullbacks if large sell orders appear later. Short-term operations should consider order book depth and changes in fund flows, remaining alert to the risk of short-term corrections caused by concentrated but unsustainable buying. In the medium to long term, ongoing monitoring of on-chain holdings and ETF fund flows is necessary to assess market structural trends.
