US Dollar (USD) surges to 75/100 bullish as safe-haven flows and hawkish Fed rate expectations drive currency strength above the 99.00 technical level.
This briefing explains why the greenback dominated the London session, which major pairs suffered most, and what data releases could extend or reverse the dollar's rally.
What Happened
The US Dollar Index held gains above 99.00 on Tuesday as rising odds of a more hawkish Federal Reserve stance combined with geopolitical uncertainty to anchor safe-haven demand. Trump's cancellation of planned military action against Iran—reported as he "called off Iran attacks"—paradoxically strengthened the greenback by reducing immediate escalation risk and capping oil prices, which had previously supported commodity-linked rivals. This narrative shift consolidated the dollar's technical position and reinforced expectations that the Fed may maintain a firmer monetary policy posture amid sticky inflation.
The broader FX session reflected a classic risk-off environment tempered by dollar strength. While Japan's GDP beat estimates at 0.5% QoQ and 2.1% YoY, the yen remained subdued as the Ministry of Finance signaled FX intervention readiness and Japanese officials vowed to shield US bond markets from further appreciation pressures. Simultaneously, the Australian and New Zealand dollars fell sharply as bullish USD sentiment overwhelmed the positive RBA messaging—eight of nine board members backed the May rate hike, yet uncertainty around pause risks and China slowdown fears weighed on both antipodean currencies. The Canadian dollar retreated to 1.3750 as crude oil slipped below $102.00, stripping away the petro-currency tailwind that had supported loonie strength.

Market Reaction
The currency market bifurcated sharply: safe-haven assets and the greenback rallied together, while cyclical and commodity-sensitive currencies capitulated. EUR/USD fell below 1.1650 despite hawkish European Central Bank messaging, illustrating how divergent Fed-ECB policy expectations and general risk aversion overwhelmed euro support factors. The widest sentiment divergence emerged between the US Dollar at 75/100 bullish and the New Zealand Dollar at 40/100 bearish—a 35-point gap that underscored how tightly exchange rates now track US monetary policy and geopolitical risk appetite.
Sterling softened on dual headwinds: UK political turmoil and the gravitational pull of Fed hawkishness sucked demand into dollars at GBP's expense. Even the Swiss franc, typically a beneficiary of risk-off moves, struggled to outperform the greenback, capped at 52/100 neutral as the dollar's yield appeal and safe-haven status proved more compelling than traditional franc strength. By London's close, the market had clearly repriced the probability of sustained US monetary tightness, with price action confirming technical support at round levels and option-implied volatility climbing across major pairs.
What's Driving the Move
Three key threads run through the bullish US Dollar story:
- The US Dollar Index held gains above 99.00 as rising odds of a hawkish Federal Reserve stance solidified safe-haven demand and reinforced expectations of firmer monetary policy.
- Trump's cancellation of planned Iran military action capped crude oil below $102.00, reducing geopolitical escalation risk and cutting into the oil-supported strength of commodity-linked currencies like the Canadian and Australian dollars.
- Japan's stronger-than-expected Q1 GDP (0.5% QoQ, 2.1% YoY) failed to lift the yen as the Ministry of Finance signaled readiness to intervene and protect US bond markets, demonstrating central bank determination to resist unilateral currency appreciation.
