• Iran struck three oil tankers in the Strait of Hormuz — threatening roughly a fifth of global oil supply and pointing to sharp crude price and shipping cost increases. • Nvidia agreed to acquire AI platform Hugging Face for $12.9 billion — cementing its hold over the AI model ecosystem and inviting antitrust review in the US and EU. • Canada matched US tariffs after trade talks collapsed — marking a serious breakdown in North America's largest trade relationship with ripple effects across autos, energy and supply chains.
