The US dollar strengthened on Monday following the announcement of expanded sanctions on Iran and new tariffs on Canadian goods. This marked a rebound after the dollar had fallen to three-month lows in recent weeks. The moves came as the Trump administration sought to increase economic pressure on Tehran and address trade imbalances with Canada, according to livemint.com.
The dollar’s gains followed US Treasury Secretary Scott Bessent’s statement about the expansion of secondary sanctions aimed at cutting off Iran’s economic lifelines. Concurrently, the US imposed tariffs on a range of Canadian imports, which contributed to a decline in the Canadian dollar, or loonie. These coordinated actions reflect the administration’s dual approach to foreign policy and trade enforcement, as reported by livemint.com.
The dollar’s rise comes amid ongoing geopolitical tensions and trade disputes that have influenced currency markets globally. The sanctions on Iran represent a continuation of US efforts to isolate the country economically, while the tariffs on Canada highlight persistent trade frictions between the two neighbors. The dollar’s performance contrasts with recent weeks of weakness, underscoring the impact of policy announcements on forex markets, per livemint.com.
The dollar’s advance on Monday ended a period of volatility that saw it hit three-month lows. The US Treasury’s sanctions expansion and tariff announcements were made public on August 24, 2026, marking a significant policy shift with immediate effects on currency valuations, according to livemint.com.
