Bitcoin surged to $81,385, jumping 26% in one week.

Bitcoin's price surged to $81,385, a 26.16% increase over the past seven days, driven by several factors including institutional investor capital, market liquidity, and buying in the derivatives market.

August 25, 2026 – Bitcoin (BTC) rebounded to $81,385, or approximately 2.66 million baht, a strong 26.16% increase over the past seven days, the strongest since May 2026. The price had previously fluctuated around $60,000. This rebound is driven by several factors, including institutional investor capital, increased market liquidity, and buying pressure in the derivatives market.

There are four key factors supporting this recent surge in Bitcoin's price that are worth watching:

1. Improved macroeconomic liquidity.

Expectations of an increase in the U.S. Treasury's bond-buying program are boosting liquidity sentiment and putting downward pressure on the dollar, leading to renewed interest in Bitcoin and gold.

2. Money flowing into Spot Bitcoin ETFs.

The Spot Bitcoin ETF in the US saw net inflows of approximately $1.9 billion over the five trading days ending August 21st, reflecting renewed buying from institutional investors.

3. Short positions were liquidated, accelerating buying pressure.

The rapid upward movement led to the forced closure of numerous leveraged short positions, with reports of liquidations exceeding $4,300 billion, triggering further buying pressure and accelerating the price increase.

4. Breakout triggered increased buying pressure.

Bitcoin's breakout from the price range it had accumulated over several months signaled a technical breakout and attracted momentum and algorithmic trading enthusiasts to reinforce the buying pressure.

Signals that still need to be watched.

Although Bitcoin's price has increased by 26.16% in the past 7 days, its 90-day return is still only 6.83%, and it's down 7.66% compared to the beginning of the year. The RSI is moving into overbought territory, which could increase the risk of a short-term correction. As a result, the market is watching to see if Bitcoin can hold above the support level of $77,000–$78,000 and retest the $80,000 level. This week's Jackson Hole meeting by the Federal Reserve (Fed) could also be another factor adding to the volatility in the cryptocurrency market.
