US Markets Plummet as US-Israel Conflict with Iran Sparks Economic Concerns

US markets witnessed a significant downturn on Thursday, marking their biggest slump since the onset of the US-Israel war with Iran. The Dow closed 450 points down, while the S&P 500 dipped 1.7%. The tech-heavy Nasdaq fell 2.3%, plunging into correction territory, which occurs when an index falls at least 10% below its most recent peak.

The conflict has led to a surge in oil prices, reaching levels not seen since Russia's invasion of Ukraine in 2022. At the end of the day on Thursday, Brent crude oil, the global benchmark, was about $107 a barrel, while US crude hit $93 a barrel. Average US gas prices at the pump reached $3.98 a gallon, according to AAA.

Despite the soaring prices, Donald Trump said that oil prices “have not gone up as much as I thought” during a cabinet meeting on Thursday. He predicted that prices would “come back down to where it was, and probably lower,” and that the impact on the stock market would reverse once the conflict ends.

Markets have been growing weary of Trump's mixed signals on the US's stance in negotiations with Iran. Stocks dipped on Thursday morning after Trump posted a warning to Iranian negotiators that they “better get serious, before it’s too late.” However, later in the morning, Trump said that there were “very substantial talks” happening with Iran and that the country allowed 10 oil tankers to pass the blocked strait of Hormuz.

The White House announced it will extend a pause on Iranian energy infrastructure strikes by 10 days, until 6 April. A new report estimates US inflation will average 4.2% this year, compared with an average of about 2.6% in 2025, according to the Organization for Economic and Cooperation and Development (OECD). The increase in inflation reverses what was expected to be strong growth for the global economy before the conflict began.
