Now for a look at the reaction of global markets to the new Fed chair's comments. World stocks were set to snap a record 15-month long winning streak on Wednesday, tumbling another quarter percent. That came after Fed chair Jerome Powell suggested the possibility of four U.S. interest rate increases this year instead of three. European shares lost around 0.3 percent on Wednesday. MSCI's all-country index fell 0.3 percent, while its emerging market equities fell 1 percent. That followed a 1.4 percent tumble in Hong Kong. Meanwhile, Japan's Nikkei also lost 1.4 percent and snapped a five-month run of gains.
