Samsung Warns Oil Shock From Iran War Could Raise Production Cost

Oil markets are in turmoil in March 2026, and big tech companies are starting to feel the effects. Since the U.S.-Iran war disrupted shipping through the Strait of Hormuz, a passage that carries about 20 % of the world’s oil, prices have surged sharply, at times topping $100 per barrel. This sudden rise isn’t just bad news for fuel bills.  On March 12, Samsung Display’s CEO warned that climbing oil and energy costs could push up production expenses across the tech supply chain. The conflict’s impact on raw materials and manufacturing could reshape cost structures for electronics in 2026 and beyond.
