Treasury fills $6 billion in 20- to 30-year bonds, Bitcoin falls below $80,000

The US Treasury filled its full $6 billion cap in 20- to 30-year bond buybacks on Tuesday. Bitcoin price fell below $80,000, failing to rally as it did in August when a surprise policy announcement doubled buyback size. Traders viewed the Tuesday operation as routine liquidity support, with dealers offering $10.7 billion and Treasury accepting $6 billion across six bonds at a cash outlay of about $3.8 billion. The price response to later buyback operations has faded, and Bitcoin has since slipped further below $80,000.
