USD/IRR & Oil Surge as Iran Rejects Ceasefire, Hormuz Strait Remains Closed

Geopolitical risk is escalating sharply as Iran reportedly refuses to reopen the Strait of Hormuz in exchange for a ceasefire, sending shockwaves through forex and commodity markets. US President Trump has warned of imminent massive strikes against Iranian power plants and bridges, raising the prospect of a significant military escalation. Iran has received Pakistan's peace proposal but has rejected any temporary ceasefire arrangement, signaling a hardened negotiating stance. The Strait of Hormuz is a critical chokepoint for roughly 20% of global oil supply, and its continued closure is driving crude oil prices higher, which in turn is pressuring oil-importing currencies such as JPY, EUR, and INR while supporting commodity-linked currencies like CAD and NOK. Safe-haven flows are boosting USD, CHF, and JPY demand. Traders should monitor USD/CAD for potential downside as elevated oil prices support the Canadian dollar, while USD/JPY may see competing forces between yen safe-haven demand and dollar strength. Volatility across major pairs is expected to remain elevated until a diplomatic resolution emerges.
