The change in the situation in the Middle East is driving significant fluctuations in the capital markets.

Affected by the re-opening of the Strait of Hormuz, the three major stock indexes in the United States opened high and rose on the 17th, with the gains narrowing in the afternoon and all three major indexes significantly rising at the close; while international crude oil futures prices plummeted, with the light crude oil futures prices for May delivery on the New York Mercantile Exchange falling by more than 11%. Anthony Salimbeni, chief market strategist at Ameriprise Financial, said that for investors, this means that there is a way for the US and Iran to end the conflict and keep the Strait of Hormuz open, and the market has withdrawn expectations for the worst-case scenario. Although international oil prices have been lowered due to news, investors' concerns about the impact of US-Iran conflict on the global economy have not completely dissipated. Analysts at the Dutch bank stated that as long as oil transportation through the Strait of Hormuz remains abnormal, the spot market will become increasingly tense. Mohamed El-Erian, economist and professor at the Wharton School of the University of Pennsylvania, also stated that the true impact of the opening of the Strait of Hormuz depends on its sustainability. Craig Johnson, Managing Director and Chief Market Technician at Piper Sandler, a US investment bank, stated earlier that the rapid rebound in the US stock market is masking vulnerabilities beneath the surface. Although short-term momentum has significantly improved, the foundation for an upward trend in the medium term is still not stable.
