Fact Check: Did Trump order a stock market shutdown amid conflict with Iran?

WASHINGTON, DC: A rumor spread rapidly on social media in late February 2026, claiming President Donald Trump had declared a national emergency and ordered the complete shutdown of US stock markets in response to rising tensions with Iran. The claim gained traction across Twitter, Facebook, and other platforms, raising questions among investors and the general public. Here’s a closer look at the origins of the rumor and the facts behind it.

Claim: Trump ordered a stock market shutdown

A widely shared post on social media suggested that President Trump invoked the International Emergency Economic Powers Act (IEEPA) to halt all trading on US exchanges. The post alleged that Trump warned of a threat to the American financial system and instructed an “immediate closure of all trading” until the system was “fully stabilized.”

The claims specifically mentioned that the New York Stock Exchange (NYSE), NASDAQ, and other major US exchanges would be closed indefinitely due to escalating tensions between the US and Iran. Viral tweets and posts accompanied the assertion with alarming headlines, including “Trump Declares National Emergency, Orders FULL SHUTDOWN of the Entire US Stock Market.”

Fact Check: No official confirmation 

These claims are false. There was no announcement from the White House, the Securities and Exchange Commission (SEC), or any other government or financial authority confirming such an action. The IEEPA cited in the posts allows the President to control certain financial transactions during a declared national emergency but does not automatically authorize a stock market shutdown.

A complete halt of all US trading would constitute an extraordinary and unprecedented measure, one that would be widely and immediately publicized by official sources. Investors and financial institutions rely on real-time confirmations from exchanges and regulators, none of which occurred in this case.

Iran missile strikes escalate Middle East tensions amid US conflict

The rumor coincided with a series of missile strikes launched by Iran on February 28, 2026, targeting Israeli sites and multiple US military bases in the Middle East. According to Iran’s semi-official Fars news agency, the strikes hit the headquarters of the US Navy’s Fifth Fleet in Bahrain, as well as major bases including Qatar’s Al-Udeid Air Base and Al-Salem Air Base in Kuwait.

The missile attacks followed US and Israeli military operations in Iran, heightening regional tensions and fueling speculation online. However, despite the chaos and concern, the US stock market remained fully operational, and no official emergency shutdown was ever declared.
