USD/JPY gains as Fed rate hike expectations pressure Japanese Yen

USD/JPY advances, although easing US-Iran tensions may curb safe-haven demand and offset the impact of elevated US CPI readings.
2% underlying inflation prompted BoJ policymakers to call for faster rate increases as the central bank's target was reached.
Weak domestic consumption and uncertainty over AI demand led several BoJ members to warn against tightening too quickly.

158.90 is the approximate level for USD/JPY during Wednesday's Asian session. The pair is advancing for a second consecutive day. Support for the US Dollar (USD) followed the latest inflation release, which reinforced market expectations of a Federal Reserve rate increase in December. The CME FedWatch Tool now puts the market-implied probability of a hike next month at approximately 91%.

October's US Consumer Price Index increased 0.4% month-on-month, above the 0.3% forecast but below September's 0.6% rise. Excluding food and energy, Core CPI advanced 0.3%. That matched September's rate and exceeded the 0.2% estimate. Annual figures for October were not published by the Bureau of Labor Statistics because of last year's government shutdown.

Growing hopes of a diplomatic settlement to the US-Iran conflict could reduce safe-haven demand, creating headwinds for the Greenback despite the supportive inflation readings. US President Donald Trump indicated that additional military strikes against Iran might not be needed. At a G7 meeting, US Secretary of State Marco Rubio also said major combat operations were no longer necessary. Meanwhile, Congressional Democrats are considering using the approaching government funding deadline to press the Trump administration towards a peaceful resolution.

8/10 Hawkish Score: Goolsbee’s ‘real inflation issue’ Warning Supports Dollar

An 8/10 FXS Speechtracker score placed the Fed’s Goolsbee well above his 6.8/10 historical average, reflecting a distinctly more hawkish stance and greater concern over persistent price pressures. He described the latest CPI as “borderline disturbing,” said services inflation was “not coming down,” and warned of “a real inflation issue” that the Fed is “going to have to deal with,” suggesting a lower threshold for further tightening or an extended period of restrictive policy. Such a combination typically supports the Dollar while weighing on risk-sensitive currencies. His repeated focus on overheating prices and the danger of inflation expectations becoming entrenched strengthens the signal that easing is likely to be postponed unless incoming data establish a clear disinflation trend.

For the Japanese Yen (JPY), the summary of opinions from the Bank of Japan (BoJ) October meeting showed policymakers calling for faster rate increases after underlying inflation reached the central bank's 2% target. Expectations of a December hike were reinforced by one member's explicit call for the BoJ to deliver its next increase "without becoming overly cautious," but divisions remained evident. Several members warned against proceeding too rapidly, pointing to subdued domestic consumption and uncertainty over whether AI-driven demand could be sustained.

216bp Spread: USD/JPY in Focus as Rate Gap Fails to Sustain Recent Highs

A slightly softer interest-rate differential backdrop is highlighted by analysts at Societe Generale, who note that "10y UST/JGB spreads narrow to 216bp (-5bp), failing to gain foothold above 220bp." In their view, the spread's fading momentum may help account for the more restrained tone in USD/JPY, with the pair consolidating around recent levels before key US data.

Japanese Yen: Key Questions

Japanese Yen: Main Drivers

Among the world's most actively traded currencies, the Japanese Yen (JPY) broadly reflects Japan's economic performance. More specific influences include Bank of Japan policy, the gap between Japanese and US bond yields, and traders' appetite for risk, alongside other factors.

Japanese Yen: The Influence of Bank of Japan Decisions

Currency control is part of the Bank of Japan's mandate, making its actions important for the Yen. Direct intervention in currency markets has occurred on occasion, usually to weaken the currency. However, political concerns among Japan's main trading partners limit how often the BoJ intervenes. Between 2013 and 2024, its ultra-loose monetary policy widened the policy gap with other major central banks, driving Yen depreciation against its main currency peers. The more recent, gradual withdrawal of that ultra-loose policy has provided some support for the Yen.

Japanese Yen: The Role of the US-Japan Bond Yield Gap

Over the past decade, continued ultra-loose policy at the BoJ increased its divergence from other central banks, especially the US Federal Reserve. The resulting widening in the yield gap between 10-year US and Japanese bonds supported the US Dollar relative to the Japanese Yen. That differential is now narrowing as the BoJ's 2024 decision to begin gradually withdrawing ultra-loose policy combines with interest-rate cuts by other major central banks.

Japanese Yen: Sensitivity to Global Risk Sentiment

The Japanese Yen's perceived reliability and stability underpin its frequent use as a safe-haven investment. During periods of market stress, investors are therefore more inclined to move funds into the Japanese currency. Such turbulence is likely to lift the Yen against currencies regarded as riskier investments.
