Gold prices fell on Tuesday as traders assessed Middle East tensions and awaited U.S. labor-market data that could influence Federal Reserve (U.S. central bank) interest-rate expectations. Spot gold was down 0.4% at $4,428.54 per ounce by 0432 GMT, while U.S. gold futures eased 0.1% to $4,477.20. Job openings, the ADP employment report and nonfarm payrolls are due this week. Spot gold had reached its highest level in more than three months last week before falling 3% on Friday after Chair Kevin Warsh said the Federal Reserve would "have work to do" if policymakers lacked confidence that inflation was moving toward 2%. IG market analyst Tony Sycamore cited Warsh's hawkish Jackson Hole speech and renewed tensions in the Strait of Hormuz, which lifted oil prices and inflation expectations. Traders see a 66% chance of a U.S. rate hike in September and an 89% probability in December, according to the CME FedWatch Tool. U.S. President Donald Trump said he respected Warsh and that "he'll do what he has to do" on interest rates. Trump also threatened further strikes against Iran after the first direct attacks between the sides in a month. Silver fell 0.2%, platinum rose 0.4% and palladium was little changed.
