The US dollar strengthens to a week-high as markets react to renewed US actions involving Iran. Multiple reports say the move follows the US launching new strikes on Iran on Tuesday and revoking one of its oil sales licenses. The developments come after attacks on three tankers in the Strait of Hormuz, which heighten concerns about disruptions to regional shipping and energy supplies.

In response to the escalation, safe-haven currencies rise, reflecting increased risk aversion among investors. The reports characterize the dollar’s gains as part of a broader shift toward currency safety, rather than as driven by a single domestic economic factor. The combination of military escalation in the Middle East and restrictions related to Iranian oil sales contributes to market volatility and supports demand for currencies viewed as safer.

Overall, the coverage links the currency move directly to the US decision to resume strikes and tighten measures tied to Iran’s oil sector, while citing the tanker attacks in a key shipping chokepoint as the triggering context.
