Japanese yen nears intervention threshold amid Iran conflict and BOJ policy bets

The Japanese yen stayed close to the 160‑per‑dollar level that traders view as a red line for possible currency intervention. On May 27 the yen was quoted around 159.2‑159.3 per dollar, its lowest level of the month, as market participants weighed the impact of renewed fighting in Iran and the associated oil shock.

Bank of Japan Governor Kazuo Ueda adopted a cautiously hawkish tone, noting that the war‑driven energy crisis could become persistent. Analysts estimated about a 70 % chance of a quarter‑point rate hike at the BOJ’s June policy meeting. The safe‑haven U.S. dollar was steady after recent U.S. strikes on Iran, while the Australian and New Zealand dollars showed mixed moves.

Market observers said that Japan’s high exposure to higher energy prices keeps the yen under pressure, but the prospect of BOJ tightening and possible intervention could provide some support.
