Treasury Doubles Long-Bond Buybacks, and Crypto Prices Follow the Yield Curve Down

The United States Treasury announced on Wednesday that it will raise its liquidity-support buybacks of longer-dated nominal coupon securities from $2 billion per operation to at least $4 billion, running from September 9 to November 4. Long-term yields fell on the news. Digital assets moved almost immediately: CoinDesk reported bitcoin up about 6% with roughly $1.4 billion of short positions closed out, and Bitcoin Magazine noted the move began within minutes of the buyback headline.

The mechanism is straightforward. The Treasury is buying back its own long-dated paper in larger size, which supports prices at the long end and pushes yields down. CryptoSlate traced bitcoin's rise from about $64,100 to nearly $70,000 in the same window, with the 30-year yield falling back after touching 5.337%. By early Thursday CoinDesk had ether up 18% to $2,250 and every major asset except tron showing double-digit weekly gains.

The move was amplified by positioning rather than by new buyers alone. CoinDesk counted $2.74 billion of losses on the short side in 24 hours, which it described as larger than the short-side losses during the October 2025 crash. Forced closing of those positions requires buying, which pushes prices further in the same direction.

Two forces now point opposite ways. The Treasury is acting to hold down long-term borrowing costs, while Federal Reserve officials have signalled that further tightening may still be needed. Crypto prices respond to both forces at once.
