USD/JPY was trading around 163.85 in the Asian session on Tuesday. The dollar lacked direction as investors awaited the Fed policy decision on Wednesday. CME FedWatch shows a 62% probability the Fed will keep rates at 3.50%-3.75% and signals a higher chance of a September hike. Market participants do not expect the policy statement or the chair's press conference to provide rate guidance; the chair said at the last meeting that "forward guidance is not applicable at the current policy juncture."
