USD/JPY is compressing into a symmetrical triangle pattern just below multi-decade highs, with the US-Iran conflict pushing Brent crude above $90 a barrel and deepening headwinds for the yen.
"The yen is caught between a geopolitical risk premium that should support it and a terms-of-trade shock that is crushing it," said Elena Fischer, geopolitical risk analyst at Edgen. "Japan's energy import dependency means every dollar rise in crude is a direct tax on its current account."
Brent crude climbed 3% to cross $90 a barrel for the first time in more than a month as the US military completed a ninth straight day of strikes against Iran, which in turn struck targets across the region. Higher oil prices disproportionately pressure the yen because Japan relies on imported fuel for nearly all of its energy needs, widening the trade deficit and weakening the currency. Softer US inflation data last week would normally have weighed on the dollar, but the energy-driven repricing offset that effect entirely.
The pair is trading within a narrowing range bounded by a descending trendline from the July 1 high and a rising trendline from the July 3 low. RSI (14) has climbed back above the neutral 50 level to 61, while MACD has completed a bullish crossover. A convincing break above trendline resistance would bring the July 1 high at 162.84 back into focus, with potential targets at 164 and 165 given the size of the consolidation. On the downside, the rising trendline is the first support level, followed by 161.50 and the former multi-decade high at 160.73.
Intervention risk hangs over thin liquidity
Japan observes the Marine Day public holiday on Monday, keeping liquidity thinner than usual and raising the stakes for potential intervention. The Ministry of Finance has historically used low-volume sessions to maximize the impact of yen-buying operations. Japan's latest economic policy blueprint reaffirmed that monetary policy decisions will remain the responsibility of the Bank of Japan, signaling no shift in the government's stance on central bank independence.
The last time USD/JPY traded at these levels in July 1986, the yen was 40% stronger on a trade-weighted basis and Japan's current account surplus was more than double its current size relative to GDP, according to BOJ historical data. That comparison underscores how much the structural backdrop has shifted against the currency.
Tech earnings and the carry trade unwind risk
With the Fed in its pre-meeting blackout period ahead of next week's FOMC decision and Japan's nationwide CPI report unlikely to move markets, attention turns to a heavy week of tech earnings. Results from Alphabet, Tesla, Intel and SK Hynix will be watched closely after selling pressure in AI-related stocks intensified late last week. If that weakness extends, it could trigger an unwind in carry trades, creating downside risk for USD/JPY.
The correlation between USD/JPY and Fed pricing over the next year strengthened last week, though the absence of similar signals from Treasury yields suggests no single factor has become the dominant driver. The pair's relationship with US-Japan two-year and 10-year yield spreads has weakened over the past month, leaving the currency more exposed to geopolitical shocks and energy price swings.
