Treasury yields shifted unevenly in anticipation of Tuesday's central bank gathering. The two-year note, highly sensitive to interest rate changes, rose 0.032 percentage point to 4.712%, while the 10-year note saw a marginal increase to 4.987%. Conversely, the 30-year bond yield eased slightly to 5.300%.

Global volatility rippled through currency markets following the re-election of Brazilian President Luiz Inacio Lula da Silva. The Brazilian real plunged more than 10% against the dollar, and the nation’s benchmark stock index suffered a record-breaking 13% decline. Amid these shifts, gold futures climbed 0.8% to $4,022.30 per troy ounce. Oil prices retreated 1.5% to $101.76 a barrel as traders weighed the potential for renewed U.S.-Iranian diplomacy against ongoing Houthi attacks targeting Saudi Arabian infrastructure.
