Yen snaps losing streak on BOJ hike signals, weak US data

The Japanese yen snapped a five-session losing streak on Thursday, rebounding from a two-week low against the dollar after markets sharply repriced expectations for a Bank of Japan rate hike in September and U.S. retail sales posted their steepest decline in more than a year.

BOJ Rate Hike Expectations Surge

The yen's recovery came as Reuters reported that the BOJ is eyeing a rate hike as soon as its September 17-18 meeting and is considering tightening more aggressively than its recent pace of roughly twice a year, citing three sources familiar with its thinking. Markets are now pricing in nearly an 80% chance of a rate hike in September, according to Tokyo Tanshi data, up from just 24% on July 30.reuters+1

The shift follows the BOJ's July 30-31 meeting, at which the central bank held its policy rate at 1% but opened the door to a September move. A summary of opinions from that meeting, published earlier this month, showed one board member arguing that "the pace of policy interest rate hikes will be faster than market expectations," given upside risks to prices. Short-term Japanese government bond yields jumped to multi-decade highs as traders repriced for faster tightening. The two-year JGB yield stood at 1.50%, while the 10-year yield reached 2.88%.tradingeconomics+3

Weak US Data Pressures the Dollar

Adding to the yen's tailwind, U.S. retail sales fell 0.6% in July, the largest monthly drop since May 2025 and the first decline in nine months, according to the Commerce Department. Economists had expected a 0.1% increase. Sales at auto dealers dropped 1.8%, while online retail tumbled 2.2%. The control group used to calculate GDP fell 0.4%, raising fresh questions about the health of the American consumer.industryweek+2

The softer data weighed on the dollar and dampened expectations for further Federal Reserve rate increases, narrowing the interest rate differential that has kept the yen under pressure for much of 2026.

Intervention Backdrop

The yen's move also unfolded against the backdrop of recent coordinated U.S.-Japan currency intervention that briefly pushed USD/JPY down from above 163 to around 157 earlier this month. Mitsuhiro Furusawa, Tokyo's former top currency diplomat, warned on August 14 that Japan may conduct joint intervention "at any time" and signal faster-than-expected rate hikes to stem the currency's decline.cnbc+1

With the BOJ's September meeting and the preceding FOMC decision on September 15-16 now the next major catalysts, traders face a pivotal stretch for USD/JPY. DBS analysts noted they assign "nearly a 50% probability" to a September hike, with July and August wage and inflation data likely to prove decisive.dbs
