USD Surges as Trump Reimposes Iran Blockade, 20% Hormuz Shipping Toll

The US dollar has strengthened broadly as President Trump announced the reimposition of what he termed 'The Iranian Blockade,' restricting Iranian vessels and their customers from transiting the Strait of Hormuz while imposing a 20% toll on all other shipping through the critical waterway. The announcement, made via Truth Social, has sent crude oil prices sharply higher given that approximately 20% of global oil supply transits the strait daily. The toll effectively acts as a tax on global energy trade, raising inflationary concerns that could complicate the Federal Reserve's rate path under Chair Warsh ahead of the July 29 FOMC meeting. USD/CAD and USD/NOK are reacting as oil-linked currencies face crosswinds between higher crude prices and risk-off dollar demand. Safe-haven flows have boosted USD/JPY and USD/CHF, though yen strength from carry trade unwinding partially offsets dollar gains against the Japanese currency. Traders should monitor escalation risks closely, as further military developments could trigger significant volatility across commodity-linked and safe-haven pairs.
