U.S. Treasury yields fell and the dollar hovered near an 11-week low in early European trade after the government announced expanded bond buybacks. The unexpected intervention came as 30-year Treasury yields had jumped to multiyear highs earlier in the week, prompting investor concern over debt market stability.

Investors are interpreting the buyback program as a clear signal that the Treasury is prepared to support struggling debt markets. The move buoyed global sentiment, with U.S. stock futures mostly climbing higher Thursday following modest gains in the previous session.

In commodities, Brent crude surged above $93 a barrel after President Trump warned of “ECONOMIC D-DAY” for Iran, vowing to target all businesses linked to the Iranian economy. The combination of monetary reassurance and geopolitical tension drove mixed but notable market movements across asset classes.
