The IMF said Thursday it is closely monitoring the latest U.S. tariff announcements, warning that global economic uncertainty remains high. It urged countries to work constructively to ensure a stable trade environment. The IMF will provide more details in its upcoming update to the April World Economic Outlook, due later in July. This follows President Trump’s move to escalate the trade war by imposing 50% tariffs on U.S. copper imports and Brazilian goods, along with higher tariffs on 21 other countries, all starting August 1. “Trade-related developments are evolving and uncertainty remains high,” an IMF spokesperson told Reuters. U.S. officials maintain that the tariffs have not driven inflation and say recent tax cuts will offset any short-term negative effects. In April, the IMF reduced growth forecasts for the U.S., China, and other countries, warning that trade tensions and tariffs - now at record highs - pose further risks to global growth.
