Asian shares mostly fall and gold jumps more than 4% after the Fed keeps rates unchanged

Asian shares are mostly lower as a wait-and-see attitude dominates in regional markets. Gold jumped another 4% and silver was up 3.5%. The dollar weakened against the Japanese yen and oil prices rose. Gains for some technology companies reporting strong earnings failed to lift shares in Tokyo, while South Korea's benchmark surged following a bullish profit update from chip maker SK Hynix. On Wednesday, U.S. stock and bond markets held steady. There was little significant reaction to the Federal Reserves decision to keep its key interest rate unchanged, as expected. Fed Chair Jerome Powell said interest rates look to be “in a good place” for now.
