Key Moments
- USD/JPY trades just below the mid-162.00 area in thin Asian trading amid a holiday in Japan, hovering near a four-decade high.
- Verbal warnings from Japanese officials about potential intervention curb aggressive Yen selling despite a wide US-Japan rate gap.
- Rising US-Iran tensions and associated energy supply risks support both the US Dollar and USD/JPY, as markets price in a geopolitical premium.
Spot Market Overview
The USD/JPY pair is fluctuating between modest gains and slight losses during the Asian session on Monday, with trading conditions muted by a market holiday in Japan. The pair is currently quoted just under the mid-162.00s, keeping it close to the four-decade high reached earlier in July. However, upside momentum appears constrained as participants remain alert to the possibility of official action to shore up the Japanese Yen (JPY).
Market speculation about direct support for the currency has made traders wary of extending bullish positions in USD/JPY, even as the broader backdrop remains supportive for the pair.
Authorities Flag Readiness for Action
Japan’s Finance Minister Satsuki Katayama said on Friday that the government will take decisive action at any time if it becomes necessary. The explicit reminder that authorities could intervene has not yet sparked a sustained recovery in the JPY, which continues to struggle to attract strong buying interest.
A key headwind for the Yen remains the substantial interest rate differential between Japan and other major economies, which continues to underpin carry trades. At the same time, lingering economic risks linked to tensions in the Middle East are weighing on the JPY, while a mildly firmer US Dollar (USD) provides additional support for USD/JPY.
Middle East Risks and Japan’s Energy Exposure
Japan’s reliance on the Middle East for more than 90% of its crude oil has sharpened investor concerns that the domestic economy could face ongoing pressure as US-Iran tensions escalate and potential supply disruptions emerge in the Strait of Hormuz. These worries are being reinforced by continued military activity in the region.
The US military said that it carried out a ninth straight night of strikes against Iran aimed at degrading its capabilities used to attack commercial vessels and civilian mariners transiting the strategic waterway. Moreover, US allies in the region reported a new wave of attacks on Sunday, prompting traders to continue to price in the geopolitical risk premium.
Safe-Haven Dollar Gains and Fed Expectations
Heightened US-Iran hostilities are supporting demand for the safe-haven USD, with markets concerned that higher crude prices could reignite inflation pressures and potentially push the US Federal Reserve (Fed) toward a more hawkish policy stance. This environment is lending additional backing to USD/JPY.
According to the CME Group’s FedWatch Tool, traders are still pricing in the possibility of at least one interest rate hike by the Fed in 2026. This positioning underpins US Dollar bulls and strengthens the argument for further near-term appreciation in the USD/JPY pair. In this context, any corrective dips are likely to be viewed as buying opportunities and could remain shallow.

Japanese Yen – Structural Drivers
The Japanese Yen (JPY) ranks among the most actively traded currencies globally. Its valuation is shaped by multiple factors, including the performance of the domestic economy, the policy framework of the Bank of Japan (BoJ), interest rate differentials – particularly with the United States – and overall risk appetite in global markets.
Bank of Japan Policy and Market Interventions
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.
Yield Differentials and Their Influence on JPY
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.
Risk Sentiment and the Yen’s Safe-Haven Role
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.
