The Japanese yen has tumbled to the psychologically critical 160 level against the US dollar, a threshold that prompted a massive $35 billion intervention by the Bank of Japan (BoJ) in late April. The USD/JPY pair climbed to this level on Thursday, its highest since April 30, extending a recovery from May lows and rekindling speculation that Japanese authorities could again step in to support the currency.
The slide came despite surprisingly strong Japanese GDP data. The economy expanded by 1.8% in the first quarter, beating forecasts of 1.3% and accelerating from 0.7% in the final quarter of last year. Consumer spending ticked up 0.3%, though a 0.7% drop in capital expenditure partially offset the gains. However, the yen failed to find a bid as markets focused on the risk of a second‑quarter slowdown fueled by the ongoing Middle East conflict and its impact on Japan’s energy imports.
Fresh geopolitical turmoil added to the risk‑on mood that paradoxically weakened the yen. Israel launched strikes against Iran, threatening the ceasefire, and the US is reportedly considering steering frozen Iranian assets toward the reconstruction of Gulf allies—a move that could prolong tensions and keep oil prices elevated. Japan, a major importer of Middle Eastern crude, remains highly vulnerable.
Simultaneously, robust US economic data has strengthened the dollar. Last week’s reports showed job openings rising, the economy adding over 172,000 jobs, and expectations that upcoming CPI figures will reveal sticky inflation, which could push the Federal Reserve to hike rates at least once this year. This hawkish outlook contrasts sharply with the BoJ’s ultra‑loose policy, widening the yield differential and adding upward pressure on USD/JPY.
The BoJ and Japan’s Ministry of Finance have repeatedly warned that they are watching currency moves with “a high sense of urgency” and stand ready to act against disorderly speculative moves. The memory of the record intervention in October 2022, when the MoF spent even larger amounts to buy yen, still looms large. Officials have identified 160 as a critical line in the sand; however, traders note that any move above it could quickly propel the pair toward 162, barring official action. The British pound is also holding above a one‑week low versus the yen near 182.00, supported by the Bank of England’s higher‑for‑longer rate stance but capped by the same intervention fears. GBP/JPY remains range‑bound between 180.00 support and 185.00 resistance, with a break above 185.00 likely requiring a significant catalyst.
