How US sanctions on Iran ripple through global markets and consumers

# Why This Matters The latest US sanctions on Iran represent a critical pressure point in global energy markets at a moment when supply is already constrained. By targeting aviation, technology, and shipping sectors simultaneously, the sanctions restrict Iran's ability to export oil and refined products, which directly tightens worldwide crude supplies and pushes prices higher at gas pumps and heating oil retailers across North America and Europe. The ripple effects extend far beyond energy: disruptions to Iran's shipping and tech sectors complicate trade routes that move goods from Asia to Europe, adding friction and costs to already strained supply chains for everything from semiconductors to consumer goods. For ordinary consumers, this means sustained pressure on inflation in transportation, heating, and manufactured products, while companies dependent on efficient global logistics face narrower profit margins or higher prices for their customers.
