The U.S. Treasury doubled its bond buyback program this quarter, targeting older, less liquid securities to improve market functioning and reduce outstanding debt supply. The two-year Treasury yield fell 8 basis points to 4.72 percent, reflecting compressed duration risk and increased demand for shorter-dated instruments.

Reduced Treasury supply typically pushes yields lower across the curve and forces institutional investors into riskier assets. The compression also lowered borrowing costs for corporations, supporting equity valuations and broad risk appetite.

Crypto markets responded sharply. Bitcoin climbed 5.1 percent to $72,603, while Ethereum rose 4.1 percent to $2,317. Traditional equities moved differently: the Dow Jones Industrial Average fell 1.3 percent to $52,759, and the S&P 500 dropped 0.9 percent to $7,641. The divergence reflects crypto's outsized sensitivity to direct liquidity injections compared with broader equity indices.

The Treasury will announce its next quarterly refunding details on Nov. 1, offering guidance on future buyback volumes and their implications for bond supply and market liquidity.
