USD/JPY Surges to 40-Year High as Dollar Strength Dominates FX

USD/JPY has surged to a 40-year high during Monday's Americas session, reflecting overwhelming dollar strength and persistent yen weakness. The rally comes amid a confluence of bullish factors for the greenback, including rising geopolitical tensions in the Middle East that are driving safe-haven flows into the dollar over the yen, and crude oil settling at $84.91 — a headwind for energy-importing Japan. European stocks finished strong while Wall Street built on momentum, reinforcing risk appetite that typically weighs on the yen. On the trade front, fresh tensions emerged as Canada's PM Carney called the latest US tariff threats a violation of USMCA, while USTR Greer accused Canada of offering better trade deals to other nations. These trade frictions add uncertainty but have not dampened dollar demand. The pair's breakout above multi-decade resistance suggests significant technical momentum, with traders eyeing further upside. Near-term support is likely at prior resistance levels, while the absence of meaningful BOJ intervention talk allows bulls to press higher. Traders should watch for potential verbal intervention from Japanese officials as a key risk factor.
