Energy Shock: Strait of Hormuz Closure Pushes Gas Prices to 4-Year Highs

U.S. gasoline prices have reached their highest level in nearly four years, averaging $4.25 per gallon as of late April. This surge is primarily driven by the closure of the Strait of Hormuz, a vital artery for global oil supplies, which has pushed Brent crude prices above $100 per barrel, up from approximately $65 at the start of the year. The current energy spike represents a rare economic condition; gasoline prices have exceeded the $4 mark only 44 times since 1993. Historically, such price levels have preceded an average 11% decline in the S&P 500 over the subsequent six months, signaling a potential correction for equity markets as higher costs erode consumer purchasing power. Analysts at Morgan Stanley warn that supply disruptions have shifted from logistical issues to production failures, meaning price increases are unlikely to be transitory. In a worst-case scenario where the Strait of Hormuz remains closed for several months, oil prices could potentially climb to between $150 and $180 per barrel. The macroeconomic outlook is further clouded by warnings from Moody's, which suggests that the fallout from the conflict could stifle GDP and jobs growth while increasing unemployment. While the S&P 500 has already recovered from a 9% dip seen in March, the persistence of the geopolitical catalyst suggests significant downside risk remains for investors.
