USD/JPY steadied around 160.50 in Asian trading after two sessions of gains, having earlier touched a six-week high of 160.56. Price action was subdued, with markets weighing the possibility of foreign-exchange intervention by Japanese authorities. Earlier this week, Finance Minister Satsuki Katayama said the government was monitoring currency moves and reiterated its readiness to take decisive steps to support market stability.
The Bank of Japan is widely expected to raise interest rates next week as policymakers contend with higher energy costs linked to the Middle East conflict. Tensions intensified after Iran’s Islamic Revolutionary Guard Corps said it would immediately and totally close the Strait of Hormuz, warning commercial and oil vessels. Risk sentiment also shifted following reports that Israel’s IDF Home Front Command issued an early warning after launches from Lebanon towards northern Israel, while US Central Command said the US began airstrikes in Iran on Wednesday. President Donald Trump also warned of severe military action if an interim peace deal is not finalised, as Iranian officials insisted they would not back down.
Two-Way Risk and Intervention Concerns
Given the high tension in USD/JPY around 160.50, we see significant two-way risk in the coming weeks. Japanese officials are clearly signaling their discomfort, and we know from history, particularly the interventions in 2024 around this same level, that direct action is a real possibility. This creates a hard ceiling on the pair, making long positions exceptionally risky.
The upcoming Bank of Japan meeting next week is a major catalyst, with markets now pricing in a high probability of a rate hike to combat renewed inflation. The conflict-driven surge in energy prices gives them every reason to act more aggressively than previously expected. A rate hike, even a small one, would likely trigger a sharp, immediate strengthening of the yen.
Geopolitical Shocks and Trader Positioning
The closing of the Strait of Hormuz, through which over 20% of the world’s seaborne oil passes, is a severe inflationary shock that complicates the picture. This geopolitical crisis is boosting the US Dollar as a safe-haven asset, which is the primary reason the yen has not strengthened already. We expect currency volatility indexes to spike to levels not seen since the outbreak of the Ukraine conflict in 2022.
For derivative traders, this environment screams for using options to manage risk and speculate on volatility. We believe buying USD/JPY put options with a two-to-four-week expiry is a prudent strategy to position for a sudden drop from either BoJ action or direct intervention. Alternatively, a long straddle could profit from a large move in either direction, as the current deadlock is unlikely to last.
The US military action in Iran and the tense political rhetoric will keep a strong bid under the US Dollar, providing a floor for the currency pair. This means any yen strengthening could be met with dip-buying from those seeking safety in the dollar. We are therefore advising against outright short-selling the pair, favoring defined-risk option strategies instead.
