USD/JPY is approaching the resistance zone of 158.00 to 158.50 — the most technically significant ceiling the pair has faced since the January 2026 highs near 159.44. The rally from the 152.25 low has been methodical, persistent, and almost entirely driven by a single macro variable that has nothing to do with interest rate differentials, BOJ policy, or traditional yen safe-haven dynamics: the price of energy. The Strait of Hormuz is, in essence, shut off to commercial shipping. WTI crude (CL=F) closed Friday at $90.90, reflecting an increase of 12.21% for the session and a remarkable 35% for the week — marking the largest weekly gain in the history of the WTI futures contract. Brent crude (BZ=F) has surpassed $94 per barrel. RBOB gasoline futures surged by 20.18% just last week, elevating the front-month contract to heights not observed since early 2024. Japan, a nation that imports nearly all of its crude oil and around 90% of its LNG from abroad, relies heavily on supplies that have historically passed through the Strait of Hormuz. As such, it is facing this energy shock without any domestic production buffer to mitigate the impact. The outcome is a terms-of-trade shock that is concurrently favorable for energy-producing currencies while being fundamentally unfavorable for energy-importing currencies. The United States, an energy superpower that produces more crude than it consumes domestically, occupies a favorable position in that divide. Japan occupies a position marked by catastrophe. The USD/JPY is currently not influenced by carry dynamics or differences in monetary policy. It serves as a real-time referendum on the energy terms-of-trade gap between the world’s largest crude producer and the world’s most energy-dependent major economy. The gap continues to widen with each passing day that the Strait of Hormuz remains closed.
The correlation data from the past week is clear and compelling. USD/JPY demonstrated a 0.69 correlation with both LNG futures and Brent crude during the five-day trading period concluding on Friday — a connection that intensified swiftly as the Iran war escalated and the Hormuz disruption transitioned from theoretical to operational. For context, the typical dominant driver of USD/JPY over the past several years has been the U.S.-Japan interest rate differential — the spread between U.S. Treasury yields and Japanese Government Bond yields that determines the carry cost of being long yen versus long dollars. The differential remains significant and relevant; however, it has been momentarily overshadowed by the energy shock, which has taken precedence as the main price-discovery mechanism for the pair. The 30-year U.S. Treasury yield experienced its most significant weekly rise since the Liberation Day risk rout of April 2025, although the extent of this increase was roughly one-third of that particular episode’s movement. The increase in long-end Treasury yields systematically expands the U.S.-Japan rate differential, as the Bank of Japan’s yield curve control framework maintains a ceiling on Japanese long rates. This widening serves as an additional support for USD/JPY, alongside the energy terms-of-trade dynamic. The compression of USD/JPY downside risk arises from both directions at once: elevated oil prices negatively impact the yen fundamentally, while increased Treasury yields provide structural support for the dollar.
The relationship with energy was “even stronger earlier in the week before easing slightly on Friday following the softer-than-expected U.S. payrolls report” — a temporary reversal that affirms macro data continues to impact the pair, even amidst the prevailing geopolitical concerns. The 92,000 job losses in February, the rise in unemployment from 4.3% to 4.4%, and the 9 basis point repricing of 2026 Fed rate cut expectations following the report led to a momentary softening of the dollar, which briefly pulled USD/JPY off its session highs. However, the pullback attracted buyers at each significant support level, and the pair swiftly rebounded toward the 158.00 ceiling within hours. USD/JPY has made several attempts to break and maintain levels above the 158.00 to 158.50 resistance zone in recent weeks. None have held. The November 2025 peak at 157.88 is positioned within this resistance cluster, and the pair has repeatedly faced rejection when nearing that level. A daily close above 157.88 to 158.50 — a clean breakout with conviction — would serve as the technical confirmation that transitions the perspective from “testing resistance” to “trending through resistance,” bringing the 159.44 January 2026 high back into focus as the immediate target. Above 159.44, the resistance layers accumulate progressively: the psychological 160.00 level, succeeded by the 2024 high of 161.94 — the most notable medium-term overhead supply in the entire USD/JPY chart structure. A break above 161.94 would technically project toward the 61.8% Fibonacci extension of the 2020-to-2024 rally, measured from the 139.87 correction low, which places the target near 176.55 — a level that would represent the most extreme yen weakness seen since the early 1990s.
The Ichimoku framework supports the bullish structure. Two significant bearish signals that characterized the previous corrective phase have been eliminated: the lagging span has crossed above the price bars, and the price action has surpassed the now very narrow cloud. As one analyst pointed out, reverting this technical landscape to a bearish setup would necessitate “considerable doing” — a substantial sell-off that would push prices back through the cloud, which is currently positioned significantly below trading levels. RSI is trending higher above 50, and MACD has turned positive after crossing above the signal line from below — oscillator momentum aligns with the directional bias. The downside technical map indicates that the February uptrend line and 156.50 serve as the initial levels of support, succeeded by the 50-day moving average at 155.64 and subsequently 154.45. The 38.2% Fibonacci retracement of the rally from 139.87 to 159.44, positioned at 151.96, serves as a critical structural support level. A breach of this level would significantly impact the medium-term bullish perspective. Provided that level remains intact, pullbacks present opportunities for buying instead of indicating trend reversals. The structural math of Japan’s energy vulnerability is not merely theoretical — it is measurable and alarming in the present circumstances. Japan imports around 4 million barrels of crude oil daily from suppliers in the Middle East, with a notable share historically passing through the Strait of Hormuz. China relies on the Strait for roughly 30% of its LNG imports, while India depends on the route for approximately 60% of its supply. However, Japan’s overall energy import dependency is even more acute, given the country’s post-Fukushima nuclear shutdown that removed domestic base-load power generation capacity.
Every $10 per barrel increase in crude costs Japan’s trade balance approximately $15 billion annually in additional import expenditure — a direct deterioration in the current account that weighs on the yen’s fundamental fair value. With crude oil priced at $90, Japan’s yearly energy import expenses have surged by around $45 billion annually compared to the $60 baseline set for early 2025. That is not a minor balance-of-payments adjustment; it represents a structural shift in Japan’s external accounts that mechanically pressures the yen lower, irrespective of the actions taken by the Bank of Japan regarding interest rates. The LNG dimension exacerbates the oil shock. QatarEnergy’s declaration of force majeure — Qatar accounts for roughly 20 to 25% of global LNG, with 85% of its exports typically directed to Asia — impacts Japan directly and without delay. Japan, South Korea, and Taiwan have swiftly moved to issue spot tenders for alternative LNG cargoes, directly competing with European buyers for the scarce non-Gulf flexible supply from the United States, Norway, and Algeria. Asian JKM LNG spot prices surged to $25.40 per million BTU, marking the highest level since 2023. Each extra dollar per MMBtu in the cost of Japanese LNG imports results in an increase of about $2 to $3 billion in Japan’s yearly energy import expenses.
