USD Rallies as JGB Yields Spike and Energy Disruptions Roil Global FX

Global currency markets were shaken on March 13, 2026, as the US dollar continued its aggressive rally, fueled by safe-haven demand and sticky inflation expectations. USD/JPY surged to fresh highs as the pair benefited from the broad dollar bid, though the move was complicated by a sharp spike in Japanese Government Bond yields, raising questions about potential Bank of Japan policy adjustments. Energy supply disruptions added another layer of complexity, with rising crude oil prices feeding into global inflationary pressures and altering central bank calculus across major economies. The dollar's strength has been broad-based, impacting both G10 and emerging market currencies as traders seek safety amid geopolitical uncertainty and shifting monetary policy expectations. JGB yield volatility in particular has introduced significant uncertainty for JPY crosses. Market participants are closely monitoring whether the BOJ will intervene directly in currency markets or adjust yield curve control parameters. Near-term, the confluence of geopolitical risk, energy disruption, and monetary policy divergence suggests continued dollar dominance across FX markets.
