US Treasury doubles bond buybacks, Bitcoin surges to $69,749

Bitcoin surged nearly 6% to hit an intraday high of $69,749 on August 19, 2026, following an announcement from the U.S. Treasury that it will double its long-term bond buyback operations from $2 billion to at least $4 billion per operation. The liquidity-boosting move pushed the 30-year Treasury yield down from a 19-year high of 5.34% to 5.19%, sparking a broad risk-on rally. The sudden price spike triggered a massive short squeeze, wiping out over $1.2 billion in bearish crypto positions in a single hour.
