USD/JPY Holds Tight as Traders Eye War, Oil Ahead of CPI

USD/JPY traded between 157.50 and 159.50 on Thursday as market participants awaited Japan’s consumer price index, due at 7:30 p.m. ET. Traders monitored developments in the US‑Iran conflict and movements in crude oil for triggers that might end the pair’s recent consolidation.

Japan’s CPI is forecast to rebound as supply‑side pressures push consumer prices higher. The Bank of Japan has referenced conflict‑related inflation and indicated it will likely pause at its next policy meeting while leaving open a higher chance of a 25‑basis‑point move in June depending on incoming data. Inflation is the primary channel for any BOJ shift away from its current policy stance.

The pair has traded in about a 200‑pip band since late March, with the low at 157.50 and the high at 159.50. Shorter‑term technicals show the 50‑hour moving average near 159.43. A decline below 158.80 has previously accelerated selling pressure on the dollar, while a sustained break above 159.80 and moves past 160.50 would reopen a path toward 2026 highs above 160.00, where resistance clusters around 160.00–160.40 and 160.70–161.00.

Geopolitical developments tied to the US‑Iran conflict have influenced positioning. Markets sold off when the confrontation began, but safe‑haven flows were limited and attention focused on the US dollar and WTI crude. Recent sessions have shown a correlation between oil prices and USD/JPY: stronger oil has coincided with dollar strength against Asian and European currencies and with yen weakness.

The second round of talks in the Middle East, delayed for more than a week, is scheduled to resume tomorrow and continue through the weekend. Traders flagged the weekend schedule and oil market reactions as factors that could change risk sentiment heading into next week. Some market participants advised caution on position sizes ahead of potential headline‑driven swings.

A prior stall in Japanese inflation reduced immediate pressure on the BOJ to tighten policy. Many market participants have maintained short yen positions, pricing in a gradual BOJ approach unless CPI significantly exceeds expectations.

Investors and traders will follow the CPI release, oil price moves and updates from the talks closely. Any of those elements could shift positioning and produce a decisive move in USD/JPY after several sessions of range‑bound trading.
