The yen weakened to the critical 160-per-dollar mark briefly in early trades, hitting the level for the third straight session despite verbal warnings from authorities. This level is seen as a potential trigger for official intervention by Japan.
Japan's Finance Minister Satsuki Katayama stated on Friday that the country is prepared to take 'decisive action' against excessive volatility in the foreign exchange market. The yen is now set for its fourth consecutive week of decline, a streak not seen since February, largely erasing gains from previous interventions that cost $73 billion.
Market analyst Tony Sycamore from IG noted that the main question is whether officials are willing to combat macroeconomic challenges such as high energy prices and robust U.S. economic data. Previous interventions in late April had only a temporary effect, and the dollar would need to weaken below 155 to significantly impact the current trend.
“The critical question remains whether officials are willing to resume their battle against formidable macro headwinds.”

Japan's real wages increased by 1.9% in April from a year earlier, marking the fourth consecutive monthly gain. The Bank of Japan, which will review interest rates on June 15-16, considers steady rises in wages and prices as crucial for any future rate hikes.
Meanwhile, geopolitical tensions in the Middle East have bolstered demand for the dollar. Efforts by U.S. President Donald Trump to mediate peace in the region face challenges, as hostilities involving Iran-backed Hezbollah and Israel continue.
“Japan is ready to respond appropriately at any time on foreign exchange and reserves the right to take 'decisive action' against excessive volatility.”

The dollar index remained stable at 99.434, on track for a 0.5% weekly gain. Markets are also anticipating the release of nonfarm payroll data, with an expected rise of 85,000 jobs in May.
Background
The yen's decline comes amid a backdrop of rising energy prices and strong U.S. economic data, which have contributed to the dollar's strength. Previous interventions by Japan have had limited success, and the current geopolitical tensions in the Middle East add another layer of complexity to the currency market dynamics.
As the yen continues to test critical levels, market participants will be closely watching for any signs of intervention by Japanese authorities. The upcoming Bank of Japan meeting and geopolitical developments in the Middle East will also be key factors to monitor.
