On March 11, 2026, oil prices experienced significant volatility, closing more than 11% lower as traders anticipated that a coalition of countries would tap emergency crude reserves to counteract supply disruptions caused by the ongoing war in the Middle East [1]. Earlier in the trading session, both U.S. crude oil and Brent crude dropped over 17% each following a false claim by U.S. Secretary of Energy Chris Wright on X regarding the U.S. Navy escorting a tanker through the Strait of Hormuz; the post was later deleted and confirmed as incorrect by White House press secretary Karoline Leavitt [1]. Despite aggressive rhetoric from U.S. President Donald Trump and Defense Secretary Pete Hegseth, who stated that Tuesday would be "our most intense day of strikes," oil prices continued their downward trajectory [1].
U.S. equities ended the day mixed, as investors weighed the sharp pullback in oil prices against the risk of further escalation in the conflict. Market sentiment was further dampened by a CBS News report suggesting Iran may be preparing to deploy mines in the Strait of Hormuz [1]. Iran defended its strikes against Gulf neighbors, asserting that U.S. military assets in the region were "legitimate" targets, while Gulf states expressed concerns about a "huge trust gap" resulting from the attacks [1].
The conflict's global impact extended to South Korea, where President Lee Jae Myung stated opposition to the U.S. relocating air defense assets out of the country, though Seoul is not in a position to make demands [1]. In India, the war disrupted liquefied natural gas supply, affecting restaurants that rely on LPG cylinders, which constitute about 90% of the industry [1].
In the technology sector, Oracle reported an earnings beat and issued strong guidance, leading to a stock surge of up to 10% in extended trading. This positive performance soothed investor concerns about Oracle's debt load related to its AI investments [1]. However, analysts warned that a prolonged conflict could impact the semiconductor industry's access to key materials and increase costs, potentially affecting demand for chips central to the AI boom [1]. Semiconductor stocks, including SK Hynix and Samsung, were caught in the broader equity sell-off, with more than $200 billion wiped off their combined value since the start of the war, despite both stocks rallying sharply on Tuesday [1].
President Donald Trump stated on Monday that the war will end "very soon," but analysts remain cautious about the ongoing risks to supply chains and market stability [1].
CONCLUSION
The ongoing Middle East conflict has triggered sharp declines in oil prices and significant volatility across global equity markets, particularly impacting semiconductor stocks and supply chains. While Oracle's strong earnings provided some relief in the technology sector, broader market sentiment remains cautious amid escalating geopolitical risks and disruptions. The situation continues to evolve, with analysts warning of potential long-term impacts on key industries.
