The Middle East impasse and shifts in interest rate markets remain key focal points for investors. While the opening of the Strait of Hormuz is a common global expectation, establishing a long-term, stable mechanism is urgent. The United States, Israel, and Iran each have their own demands and stances, but the conditions proposed by the U.S. and Iran are difficult for the other side to accept, suggesting the situation is unlikely to improve in the short term.
