Despite ongoing Middle East conflict, the Japanese yen weakens against the US dollar during early Asian trading

    The Japanese Yen fell against the US Dollar in early Asian trading on Monday, even as the Middle East conflict moved into a fourth week with no sign of easing. The weekend saw fresh escalation linked to shipping routes and energy assets. US President Donald Trump gave Iran a 48-hour ultimatum to reopen the Strait of Hormuz to shipping or face the destruction of its energy infrastructure. Iran’s Islamic Revolutionary Guard Corps said it would completely shut the strait if Trump acted on those threats.

    Middle East Tensions Lift The Dollar

    The Jerusalem Post reported that the US is considering a ground operation to seize Iran’s Kharg Island, described as a key oil hub. The developments weighed on risk appetite and supported demand for the US Dollar over the Yen and gold. USD/JPY gains were described as limited by concern that Japanese authorities could intervene near 160.00. Another factor cited was the Bank of Japan’s hawkish interest-rate outlook, which was said to reduce downside pressure on the Yen. The Yen is influenced by Japan’s economic performance, Bank of Japan policy, yield gaps with US bonds, and market risk sentiment. The Bank of Japan used ultra-loose policy from 2013 to 2024, and a gradual shift away from it in 2024 has narrowed the 10-year US–Japan yield differential. Looking back at the events of late 2025, we saw an unusual situation where heightened Middle East conflict strengthened the US Dollar instead of traditional safe havens like the Yen. This pushed the USD/JPY pair toward the critical 160.00 level. This dynamic, where geopolitical risk supports the dollar, continues to define the trading landscape today.

    Intervention Risk Near Key Levels

    We should remember the Ministry of Finance’s actions back in the spring of 2024 when the pair first crossed 160. Records show they spent over 9 trillion yen to defend the currency then, establishing that level as a significant psychological and political barrier. This historical precedent makes the threat of intervention a very real cap on any further upside. The interest rate differential between the US and Japan, while still favoring the dollar, has narrowed from its peak in 2023. With the Federal Reserve holding rates steady through the start of 2026 and the Bank of Japan slowly normalizing its policy, the powerful carry trade that once drove the pair higher has lost some of its strength. This provides a fundamental anchor for the Yen that was previously absent. Given this ceiling created by intervention fears, selling call options on the USD/JPY with strike prices at or just above the 160 level could be a prudent strategy. This approach allows us to collect premium from the high implied volatility caused by ongoing global uncertainty. The position is profitable as long as the pair respects the intervention threat and stays below the strike price. However, we must watch for any major escalation that could trigger an overwhelming flight to the dollar, similar to what we saw during the initial market panic of March 2020. The CBOE Volatility Index (VIX) has been hovering around 17, which suggests traders are alert but not in a full panic. A sudden spike in the VIX above 25 could signal a rush for dollars that might overwhelm any initial intervention efforts by Japanese authorities.
