Yen Jumps Below ¥157 as Traders Price In BOJ Rate Hike

The Japanese yen jumped overnight and traded under ¥157 to the dollar, a level that had held for weeks, as investors priced in a higher chance of another Bank of Japan rate hike. The move followed a sudden spike described by traders as unusually sharp for a currency that had been range-bound. Japan's top five trading houses rallied on the news, a move analysts tied directly to expectations that higher domestic rates would boost their yen-denominated earnings and balance sheets. The rate story cuts both ways for Japanese equities. Furniture retailer Nitori surged, while Fast Retailing, owner of Uniqlo, fell to a near five-month low after reporting a decline in August Uniqlo sales — a reminder that a stronger yen and higher rates squeeze exporters and consumer names differently than domestic-facing firms. Investors have been sorting Japanese stocks into winners and losers based on how exposed each is to the currency and to borrowing costs. What remains unresolved is the timing of the next BOJ move. The central bank has not set a date, and a reversal in the dollar-yen rate back above 157 would undercut the rate-hike narrative driving Tuesday's trading.
