The Canadian dollar fell after US-Canada trade talks collapsed. US tariffs on Canadian goods took effect over the weekend following last Friday’s failed talks; Canada said it will impose matching retaliatory tariffs.

On the 23rd an IRGC spokesman said Iran has prepared response plans for a range of US hostile actions, explicitly including measures to counter economic pressure. He said recent US statements about waging the "most severe economic war" against Iran reflect Washington's failure to achieve military objectives and are intended to exert psychological pressure on the Iranian public; he added the US has imposed economic sanctions on Iran for 47 years.
