Gold prices gained on Friday, helped by a pullback in the dollar, although bullion was headed for a weekly fall as hotter-than-expected U.S. inflation data dented expectations for a super-sized 50-basis-point (bps) Federal Reserve rate cut.

Gold was on track for its biggest weekly climb in a month as a slew of US tariffs came into effect and as President Donald Trump named a temporary Federal Reserve governor expected to echo his calls for lower interest rates.

Gold extended gains to a third session on Thursday, supported by rising expectations of an interest rate cut by the U.S. Federal Reserve in September following tame inflation data, which also weighed on the dollar.
