Nasdaq 100 Surges on War-End Optimism; Risk-On Sentiment Lifts USD

US equity markets are rallying sharply, with the Nasdaq 100 climbing on renewed optimism surrounding potential war-end developments and strong tech earnings, notably AMD's post-earnings jump. The broad risk-on environment is supporting equity-correlated currencies while pressuring traditional safe havens. Oil prices, particularly Brent crude futures, have come under selling pressure as geopolitical risk premiums ease, which in turn is reducing inflationary pressures and shifting rate expectations. The improved risk appetite is providing a mixed backdrop for the US dollar — benefiting from equity inflows but losing some safe-haven demand. Currency pairs sensitive to risk sentiment, such as AUD/USD and USD/JPY, are seeing notable moves. Traders should monitor whether the optimism sustains, as previous war-end headlines have faded quickly. Near-term, the tech-led rally could keep risk currencies bid, but any reversal in geopolitical sentiment would quickly restore defensive positioning. Key levels on USD/JPY near 155.00 and oil-sensitive pairs like USD/CAD remain in focus.
