Gold prices saw a retreat on Friday, hovering near their lowest level in a week, amidst escalating expectations for an imminent interest rate hike in the United States. Investors are closely monitoring the release of the U.S. Consumer Price Index (CPI) data later today, anticipated to provide crucial insights into the future trajectory of monetary policy. Spot gold prices stabilized at approximately $4318.88 per ounce, after earlier reaching their lowest point since September 2nd. Prices had fallen by nearly two percent on Thursday, following the higher-than-expected U.S. producer prices for August. U.S. gold futures for December delivery also declined by 1.1 percent, to $4359.50. Market speculation suggests the Federal Reserve (U.S. central bank) may increase short-term borrowing costs at its upcoming meeting next week. This comes after the first major report in this week's inflation data series, where the Bureau of Labor Statistics reported the Producer Price Index for final demand rose by 0.4 percent last month, following a revised 0.1 percent increase in July. The U.S. CPI data, due at 12:30 GMT, is eagerly awaited by market participants for its implications on future policy. In a related development, the European Central Bank (ECB) implemented its second interest rate hike this year, aiming to curb surging inflation fueled by energy prices. The central bank cautioned that price pressures might persist for an extended period, reinforcing expectations for further monetary policy tightening, possibly by October. Although gold is often seen as a hedge against inflation, a high-interest-rate environment puts significant pressure on this non-yielding asset. Regarding other precious metals, silver in spot transactions recorded a 0.1 percent decrease, settling at $63.48. Platinum remained stable at $1777.42, while palladium declined by 0.2 percent to reach $1279.25.
