According to CNBC, Toyota, Honda and Nissan are facing potential pressure from a stronger yen and the Iran war after benefiting in their latest quarterly reports from a historically weak currency. The U.S. Treasury and Japan's Ministry of Finance jointly intervened in early August to buy yen after the currency fell past 163 per dollar, and analysts said a stronger yen would hurt exporters by forcing price increases abroad or by reducing the value of overseas profits. Vincent Sun, senior equity analyst at Morningstar, said government action to strengthen the yen would be negative for Japanese automakers. Masahiro Akita, senior analyst at Bernstein, said a 1% move in the yen typically changes Japanese automakers' operating profit by about 2%, though the impact can reach around 4% for some companies. Analysts also said the ongoing Middle East conflict could raise supply chain disruptions and raw material costs, with the Strait of Hormuz and the Red Sea important shipping routes for aluminum and petrochemicals used in car production.
