Gold prices moved lower on Monday as rising oil costs and tougher signals from U.S. Federal Reserve officials weighed on sentiment. The decline came as tensions in the Middle East intensified, pushing investors to reassess the outlook for inflation and interest rates.

A major focus for markets was Brent crude climbing above $90 a barrel. Higher energy prices can feed into broader inflation pressures, which in turn may influence central bank policy. That backdrop made gold more vulnerable, even though geopolitical risks often support demand for safe-haven assets.

Adding to the pressure, several Fed policymakers suggested that further rate increases could still be needed. Expectations of higher borrowing costs tend to hurt gold because the metal does not offer interest, making it less attractive when rates are elevated or expected to rise further.

The combination of escalating regional conflict, firmer oil prices and renewed rate-hike discussion created a difficult setting for bullion. For now, gold appears caught between support from geopolitical uncertainty and pressure from inflation worries and the prospect of tighter U.S. monetary policy.
