The yen has weakened more than 1.1% since the Federal Reserve's rate decision, as its hawkish stance outweighed expectations of an imminent Bank of Japan rate increase. Barclays' Mitul Kotecha, head of Asian foreign exchange and emerging-markets macro strategy, said the Fed decision made a BOJ hike nearly unavoidable. The dollar gained 0.7% against the currencies of major trading partners. The Fed raised its policy rate to 4.00% and lifted its longer-run rate projection to 3.2% from 3.1%, reinforcing expectations that U.S. borrowing costs could remain restrictive. Earlier Tokyo trading saw dollar-yen reach 155.72 as investors positioned for a possible 0.25 percentage-point BOJ increase and awaited Governor Kazuo Ueda's guidance, but Japanese tightening expectations have yet to offset U.S. interest-rate support for the dollar.
