USD/JPY opens lower on FM pledge to “monitor” market developments

• Middle East tensions intensified over the weekend, leading to fresh supply concerns.
• US President Trump called for a coalition to protect the Strait of Hormuz.
• USD/JPY ticked lower at the weekly opening, holds to familiar levels with a mild bullish twist.

The war in the Middle East intensified over the weekend, leading to opening gaps across the FX board. In the case of the USD/JPY pair it gapped marginally lower and trades around 159.50, following weekend comments from Japanese Finance Minister Satsuki ‌Katayama, who expressed concerns over the recent sharp depreciation of the Japanese yen, and pledged to closely monitor markets and take action against excessive volatility.

Middle East developments

The world woke up Saturday to news indicating that the United States (US) struck Iranian military installations on Kharg Island, Iran’s main oil export hub. Tehran responded quickly by launching attacks on neighbouring countries, hitting the United Arab Emirates (UAE) and Iraq’s hubs among other targets. Hezbollah claimed to be responsible for targeting the US embassy in Baghdad.

 As the weekend unfolded, tensions escalated, leading to massive back-and-forth attacks around the Strait of Hormuz.  United States (US) President Donald Trump called allies through Truth Social to help secure the corridor, while early in Asia, the Wall Street Journal reported a coalition is being formed to protect the passage, albeit indicating discussion continues on whether those operations would begin before or after hostilities end.

USD/JPY short-term technical outlook

In the 4-hour chart, USD/JPY trades with a mildly bullish bias as price holds well above the rising 20-, 100- and 200-period Simple Moving Averages (SMAs), with the short-term average clustered around 159.00 and tracking the latest advance. The Momentum indicator remains positive, with the 14-period Momentum indicator above 0 despite easing from recent peaks. The Relative Strength Index (RSI) indicator hovers just below the overbought band near 69.

Immediate support emerges at the 20-period SMA near 159.00, which protects a deeper pullback toward 158.50 and then 158.00, where prior consolidation and the rising 100-period SMA begin to converge. As long as the pair holds above these levels, buyers would remain in control, keeping focus on resistance at the recent high around 160.00, followed by a higher barrier near 160.50. A sustained break below 158.50 would weaken the bullish structure and expose the next downside level at 158.00, but the broader uptrend only faces more material risk while price trades above the 200-period SMA near 155.80.
