Spot gold and gold futures prices moved higher this morning after the U.S. Federal Reserve voted as expected to keep interest rates unchanged, but buying momentum later slowed as investors assessed remarks from the Fed chair reiterating the commitment to bringing inflation back to the long-term target of 2 percent. As of 8:01 a.m. Thailand time, spot gold was up 0.2 percent at 4,074.79 U.S. dollars per ounce, after surging 1.2 percent to a one-week high of 4,100.42 dollars per ounce. Gold futures rose 0.9 percent to 4,072.40 dollars per ounce. Gold initially drew support from lower U.S. Treasury yields and a weaker U.S. dollar index immediately after the meeting, before prices trimmed gains as investors reconsidered the Fed chair's remarks that the central bank remains committed to steering inflation back to the 2 percent target, even as it decided to hold monetary policy steady at this meeting. The U.S. dollar index was last trading near 100.9, while the 10-year U.S. Treasury yield recovered from its post-meeting lows, reducing the tailwind for gold. Analysts at ANZ said gold prices initially rose after the Fed held rates, as lower bond yields and a softer dollar enhanced the appeal of gold. However, gold later pared gains after the market assessed that Fed policymakers are still likely to keep rates elevated to evaluate the inflationary impact of the conflict in the Middle East.
