Yen hits seven-month high as BOJ rate hike odds near 97%

The Japanese yen has climbed to its strongest level since mid-February, with USD/JPY falling to around 153 as markets price in near-certain odds of a Bank of Japan rate hike next week. The move marks a dramatic reversal for a currency that hit 40-year lows just months ago.

Money-market pricing now assigns roughly 97% odds to a 25-basis-point increase at the BOJ's September 17–18 meeting, up from 52% a month ago, according to overnight index swap data. The pair has declined more than 4% in September alone across just six trading sessions. Commerzbank puts the probability even higher, noting that "an interest rate hike next week is now priced in at roughly 96%, and the market expects further hikes to follow quickly thereafter".fxstreet+1

Hawkish Signals and Carry Trade Unwind

BOJ board member Hajime Takata has stated that a 25-basis-point step "is not set in stone" and that back-to-back hikes are possible. Goldman Sachs The Goldman Sachs Group, Inc. ↘ 0.88% has brought forward its BOJ hike outlook to September, raising its terminal rate target to 1.75%. Rabobank noted that market chatter around a potential 50-basis-point hike has intensified — a move that "would be the first such move since 1989, when it was still in a bubble".bitget+2

The speed of the yen's appreciation has triggered a wave of carry trade unwinding, as investors who borrowed cheaply in yen to fund higher-yielding assets elsewhere rush to close positions. When USD/JPY broke below 155, stop-loss orders and option hedging collectively triggered large-scale dollar selling.

Wall Street Split on What Comes Next

Major banks are divided on how much further the yen can climb. Eric Nelson, a strategist at Wells Fargo ↘ 0.25%, said it would be "very difficult" for the BOJ to surpass the tightening expectations already reflected in markets. JPMorgan ↘ 0.32% cautioned that yen strength itself could reduce the need for additional rate increases, with co-head of global FX strategy Meera Chandan noting that Japanese authorities would want to avoid "excessive strength" as well as weakness.bloomingbit

Bank of America ↘ 0.18% took the opposite view, arguing the yen could find additional momentum if the BOJ accelerates its pace of rate increases. Manulife Investment Management ↗ 1.26% also sees room for continued gains if the BOJ confirms the possibility of further tightening before year-end.bloomingbit

The Week Ahead

The Federal Reserve decides on rates September 16, followed by the BOJ on September 18 — placing two consequential central bank decisions within 48 hours of each other. U.S. consumer inflation data due September 11 will offer further clues on the Fed's path. Citigroup ↗ 0.51% said the current decline in USD/JPY could continue toward 152, but warned that a Fed rate increase would make it difficult for the pair to settle sustainably below 155.financefeeds+2

With the September hike largely priced in, the reaction will hinge less on the decision itself than on Governor Kazuo Ueda's press conference and what he signals about the months ahead.tradingnews
