Iran Sanctions Threat Boosts USD Safe Haven Appeal Against Risk Pairs

The US dollar gained 0.3% against risk-sensitive currencies after President Trump announced the immediate end of Iran sanctions relief discussions. Trump cited Iran's Supreme Leader's claims of victory against Israel as the reason for halting negotiations. USD/CAD rose 0.4% to 1.4380, while AUD/USD fell 0.35% to 0.6150 as commodity currencies weakened on geopolitical tensions. Oil prices spiked 2.1% on supply disruption fears, providing mixed signals for petro-currencies. The dollar index climbed to 106.80, recovering from earlier losses. Safe haven flows also benefited USD/CHF, rising to 0.9120. Technical analysis shows USD/CAD testing resistance at 1.4400, with momentum indicators turning bullish. The escalation in Middle East tensions reinforces dollar strength against commodity and emerging market currencies, with further gains likely if geopolitical risks intensify.
