Yen Caught Between Oil Shock and BOJ Caution
The Iran-driven oil shock is complicating the BOJ’s rate path, leaving USD/JPY caught between rising import inflation in Japan and persistent U.S. Dollar strength.
USD/JPY held a firm tone on Wednesday as markets continued to digest the economic fallout from the Iran conflict and the resulting surge in global energy prices. Disruptions around the Strait of Hormuz have rattled energy markets and lifted crude prices, an especially sensitive development for Japan given its heavy reliance on imported fuel. The shock has raised concerns about rising import costs and renewed inflation pressure in Japan while simultaneously weighing on the country’s growth outlook.
For the BOJ, the oil crisis is complicating an already delicate normalization process. Governor Kazuo Ueda has acknowledged that higher crude prices could weaken Japan’s terms of trade and undermine underlying economic momentum even as they push inflation higher, forcing policymakers to tread carefully on further rate increases. Markets are increasingly leaning toward a cautious BOJ stance in the near term, with the central bank weighing whether oil-driven inflation represents a temporary supply shock rather than the sustained demand-driven price pressures needed to justify faster tightening. The result is a policy balancing act: rising energy costs pushing inflation higher, but the risk that those same costs ultimately slow Japan’s economy.
USD/JPY Daily Price History
In the above chart, USD/JPY rates are once again pressing important resistance carved out below 160.00, defined by the swing highs at the start of 2025 and early-2026. Price action over the past year-plus appears to have created an ascending triangle, suggesting a topside move may be around the corner. Momentum is accelerating again, with Slow Stochastics holding near overbought territory and MACD continuing to run higher above its signal line. A breach of 159.45 would signal the next leg up; traders would be well-reminded that intervention efforts have been previously discussed when USD/JPY has encroached 160.00.
