Japanese Yen struggles near 160.50 as intervention fears offset US Dollar strength

USD/JPY struggles for direction on Thursday as fears of intervention by Japanese authorities cap upside, even as the US Dollar (USD) strengthens amid renewed hostilities between the United States and Iran.

At the time of writing, the pair is trading around 160.50, a level that previously triggered intervention from Tokyo in late April. Japanese authorities have repeatedly signaled their readiness to take decisive action against excessive and disorderly currency moves.

On the geopolitical front, US President Donald Trump warned of further strikes against Iran as tensions escalated earlier this week after Tehran downed a US Apache helicopter near the Strait of Hormuz.

However, diplomatic efforts remain underway. Reuters reported on Thursday, citing Iranian and Western sources, that Tehran and Washington are still exchanging messages over the details of a memorandum of understanding, including mechanisms for the release of frozen Iranian funds.

The latest flare-up has cast doubt on the durability of the ceasefire announced in April and dented hopes for a near-term peace deal. This keeps geopolitical risks in play and supports safe-haven demand for the US Dollar.

The US Dollar Index (DXY), which tracks the Greenback's value against a basket of six major currencies, is trading around 100.23, its highest level since April 6.

The Greenback is also drawing support from hawkish Federal Reserve (Fed) expectations as the inflation outlook deteriorates amid the ongoing energy shock.

Data released on Thursday showed the Producer Price Index (PPI) rose 6.5% YoY in May from 5.7% in April, above market expectations of 6.4%. Meanwhile, data released on Wednesday showed Consumer Price Index (CPI) inflation accelerated to 4.2% from 3.8%, the highest level since April 2023.

Still, underlying inflation pressure remained relatively contained. Core PPI held steady at 4.9% YoY in May, below the 5.4% forecast, while Core CPI edged up to 2.9% from 2.8%.

Apart from US Dollar strength, elevated Oil prices remain a drag on the Japanese Yen (JPY) in the near-term, given Japan's reliance on imported energy from the Middle East.

Meanwhile, the BoJ's gradual approach to policy normalization keeps the interest rate gap with other major central banks wide, a persistent headwind for the Yen.
