President Donald Trump’s latest tariffs are ready to launch. Last week, Trump signed executive orders slapping tariffs of between 10% and 41% on a range of countries, but delayed their start date until Aug. 7.

President Donald Trump just enacted a new wave of tariffs on dozens of America’s trading partners, marking a substantial escalation in ongoing trade tensions that could constitute the biggest change to the global economy in nearly a century.

Most of the new duties kicked in Thursday, hitting countries with elevated rates that mark a departure from long-standing trade norms.
