NEW YORK, June 25 (Reuters) - Gold soared to an almost six-year high on Tuesday on escalating U.S.-Iran tensions, while equity markets slid on disappointing economic data and uncertainty on whether the Federal Reserve will cut interest rates in July as has been expected.
Fed Chairman Jerome Powell said in a speech the U.S. central bank is insulated from short-term political pressures as policymakers wrestle with whether to cut rates amid slowing growth as President Donald Trump has demanded. markets have rallied this month in anticipation that Fed policymakers would cut rates, but Powell's remarks cast doubt on those expectations when he referred to the Fed's independence.
"Clearly, he's referring to comments from the White House," said Quincy Krosby, chief market strategist at Prudential Financial (NYSE:PRU) in Newark, New Jersey. "The market wants to hear the Fed remains steadfast - what it perceives is the correct path to follow in terms of monetary policy, rather than acquiescing to the administration."
The dollar rebounded and gold prices retreated after Powell's comments trimmed market expectations that the U.S. central bank will cut rates by half a percentage point next month.
