USD Faces Volatile Week: Iran Tensions & Holiday-Shortened Trading

The US dollar enters a compressed trading week with markets closing early Thursday and fully Friday ahead of Independence Day, creating conditions for heightened volatility and reduced liquidity. Geopolitical tensions have escalated over the weekend after Iran struck the commercial cargo vessel Kiku in the Strait of Hormuz, reigniting risk-off sentiment that typically supports safe-haven currencies such as USD, JPY, and CHF while pressuring risk-sensitive pairs. The Strait of Hormuz remains a critical chokepoint for global oil shipments, and any sustained disruption could drive crude prices higher, benefiting commodity-linked currencies like CAD while weighing on oil-importing nations' currencies. Traders should anticipate condensed data releases and thinner order books, which can amplify price swings across major pairs. Key pairs to monitor include USD/JPY and USD/CHF for safe-haven flows, as well as USD/CAD for oil-related moves. With multiple catalysts packed into four sessions, position sizing and risk management will be critical for navigating this holiday-shortened week.
