Gold prices moved lower on Monday as a jump in crude oil added fresh pressure to the inflation outlook. The decline came after tensions in the Middle East intensified, helping lift Brent crude above $90 a barrel and shifting investor attention toward the risk of higher consumer prices.

The rise in energy costs raised concerns that inflation could stay stubborn for longer than expected. At the same time, several U.S. Federal Reserve policymakers indicated that additional interest rate increases may still be needed to contain price pressures, adding another headwind for bullion.

Gold is often sensitive to expectations for tighter monetary policy because higher rates can reduce the appeal of non-yielding assets. Even though geopolitical uncertainty can sometimes support demand for safe-haven investments, the market focus in this session appeared to center on oil-driven inflation risks and the prospect of further Fed tightening.

The combination of surging crude prices and hawkish signals from the U.S. central bank left gold under pressure at the start of the week. Traders are likely to keep watching developments in the Middle East, moves in oil, and upcoming Fed commentary for clues on where precious metals may head next.
