Bitcoin Surges as Treasury's Bond Buyback Plan Shakes Markets

The Rally Started in the Bond Market

Bitcoin began the week near $62,800. By Friday, August 21, 2026, it was trading around $77,000 and closed up 6% at $76,943.90.

The spark was not a crypto event. It came Wednesday from the Treasury. Bessent said the government would double its buybacks of long-term debt, and the message was clear: Washington wanted to ease pressure on long-term interest rates.

Treasury yields dropped after that. When yields fall, bonds pay less to investors, so some money naturally goes hunting in riskier places like bitcoin.

Max Stuedlein at Sygnum APAC said the Treasury action was about more than one week of market noise. "The Treasury's decision to double its buybacks of long-dated government debt is aimed at addressing long-term yield concerns, where borrowing costs have been rising on concerns over US debt levels and partial crowding out by debt issuances of hyperscalers," he said.

Then the price move became sudden. Traders who had bet against bitcoin and expected it to fall were forced to buy it back quickly as the price jumped. That created a classic short squeeze. CoinGlass tracked about $2.7 billion in crypto short positions getting liquidated during the rush.
