Gold futures extended their rally to approach $4,500 an ounce, supported by an in-line CPI report that showed cooling inflation. The annual headline rate fell to 3.4%, easing pressure on the Fed's interest rate path as traders look ahead to tomorrow's PPI data. Elsewhere, the softer inflation backdrop and improved risk tone helped lift Silver futures over $66 an ounce. Copper futures also saw modest gains, trading above $6.64 amid tight physical markets and wide backwardation, as investors monitor U.S. tariffs and Chinese buying appetite.
