Japanese Yen holds ground due to potential intervention from Japanese authorities
- USD/JPY hovers near 160.00, pressured by wide interest rate gaps and high import costs.
- Escalating US-Iran conflict and potential oil blockades lend safe-haven support to the US Dollar.
- Soft July US CPI data reduced market expectations for a September Federal Reserve rate hike.
USD/JPY inches lower after registering minor losses in the previous day, trading around 159.40 during the European hours on Thursday. The currency pair hovers near the crucial 160.00 level, keeping traders on high alert for possible intervention from Japanese authorities. Despite intervention caution, the Japanese Yen (JPY) remains under fundamental pressure due to wide interest rate differentials, fiscal worries, and rising import costs.

Analysts at Commerzbank highlight that the recent move in USD/JPY has effectively unwound much of the post-intervention strength in the Japanese currency, noting that "the yen has now given back a significant part of the gains following the coordinated US-Japan intervention earlier this month." This reversal leaves markets reassessing the durability of the earlier support for the Yen as investors focus on the evolving Bank of Japan rate outlook and the potential for renewed policy action.
Meanwhile, the US Dollar (USD) gains support from escalating US-Iran tensions. Stalled diplomacy and aggressive US moves, such as threats of broader sanctions and a potential naval blockade on Iranian oil exports, have heightened geopolitical risks, reinforced by President Donald Trump's claim of "total control" over the strategic waterway.
However, the Greenback’s upside could be capped by shifting Federal Reserve (Fed) rate expectations following softer inflation metrics. July’s headline CPI dropped slightly to 3.4% year-over-year, while core CPI cooled to 2.5%, matching market forecasts. This cooling inflation has reinforced market expectations for a more accommodative Fed stance, with the CME FedWatch tool showing the probability of a September rate hike falling to roughly 36% from 48% a day earlier.
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.
