• USD/JPY strengthens as high US CPI numbers may be offset by reduced safe-haven demand as US-Iran tensions ease.
• BoJ policymakers urged faster rate hikes after underlying inflation hit the central bank's 2% target.
• Several BoJ members cautioned against hasty tightening, citing soft domestic consumption and uncertainty around AI demand.

USD/JPY extends its gains for the second successive day, trading around 158.90 during Asian hours on Wednesday. The pair gained ground as the US Dollar (USD) received firm support following the latest inflation report, which cemented market expectations for a Federal Reserve rate hike in December. According to the CME FedWatch Tool, markets are now pricing in approximately a 91% probability of a rate increase next month.

US Consumer Price Index rose 0.4% month-over-month in October, beating the 0.3% forecast even as it slowed from September's 0.6% gain. Meanwhile, Core CPI, which excludes food and energy prices, rose 0.3%, matching September's pace and topping the 0.2% estimate. The Bureau of Labor Statistics omitted annual figures for October due to last year's government shutdown.

Despite these bullish inflation metrics, the Greenback may face headwinds from diminishing safe-haven demand as hopes grow for a diplomatic resolution to the US-Iran conflict. US President Donald Trump signaled that further military strikes against Iran might no longer be necessary, while US Secretary of State Marco Rubio noted at a G7 meeting that major combat operations were no longer required. Simultaneously, Congressional Democrats are weighing the use of the upcoming government funding deadline to encourage the Trump administration toward a peaceful resolution.

Goolsbee flags ‘real inflation issue’, lifting hawkish Fed tone and supporting the Dollar

Fed’s Goolsbee delivered a distinctly more hawkish tone, with an 8/10 FXS Speechtracker score standing well above the 6.8/10 historical average and underscoring rising concern about sticky price pressures. The emphasis that the latest CPI was “borderline disturbing,” with services inflation “not coming down,” and the warning of “a real inflation issue” that the Fed is “going to have to deal with,” signals a lower bar for additional tightening or a longer period of restrictive policy, a mix that is typically supportive for the Dollar and negative for risk-sensitive currencies. Repeated references to overheating prices and the risk of inflation expectations becoming entrenched reinforce the message that policy easing is likely to be delayed unless incoming data show a clear disinflation trend.

On the Japanese Yen (JPY) side of the equation, Bank of Japan (BoJ) policymakers voiced support for accelerating rate hikes after underlying inflation hit the central bank's 2% target, according to the summary of opinions from its October meeting. One member explicitly urged the BoJ to execute its next increase "without becoming overly cautious," bolstering expectations for a rate hike at the December meeting. However, the summary also highlighted a lingering divide among policymakers, as several members cautioned against moving too quickly amid sluggish domestic consumption and uncertain sustainability in AI-driven demand.

USD/JPY focus sharpened as rate spread fails to hold above recent highs

Analysts at Societe Generale highlight that the rate differential backdrop has softened slightly, noting that "10y UST/JGB spreads narrow to 216bp (-5bp), failing to gain foothold above 220bp." They suggest this loss of momentum in the spread may help explain the more contained tone in USD/JPY as the pair consolidates near recent levels ahead of key US data.

Japanese Yen FAQs

The Japanese Yen (JPY) is one of the world’s most traded currencies. Its value is broadly determined by the performance of the Japanese economy, but more specifically by the Bank of Japan’s policy, the differential between Japanese and US bond yields, or risk sentiment among traders, among other factors.

One of the Bank of Japan’s mandates is currency control, so its moves are key for the Yen. The BoJ has directly intervened in currency markets sometimes, generally to lower the value of the Yen, although it refrains from doing it often due to political concerns of its main trading partners. The BoJ ultra-loose monetary policy between 2013 and 2024 caused the Yen to depreciate against its main currency peers due to an increasing policy divergence between the Bank of Japan and other main central banks. More recently, the gradually unwinding of this ultra-loose policy has given some support to the Yen.

Over the last decade, the BoJ’s stance of sticking to ultra-loose monetary policy has led to a widening policy divergence with other central banks, particularly with the US Federal Reserve. This supported a widening of the differential between the 10-year US and Japanese bonds, which favored the US Dollar against the Japanese Yen. The BoJ decision in 2024 to gradually abandon the ultra-loose policy, coupled with interest-rate cuts in other major central banks, is narrowing this differential.

The Japanese Yen is often seen as a safe-haven investment. This means that in times of market stress, investors are more likely to put their money in the Japanese currency due to its supposed reliability and stability. Turbulent times are likely to strengthen the Yen’s value against other currencies seen as more risky to invest in.
