S&P 500 Erases $2 Trillion in Market Value Since Iran War Began

The post says the S&P 500 has officially lost $2 trillion in market capitalization since the Iran war began, highlighting a sharp equity-market decline tied to the conflict.

Fact Check
In the context of the March 2026 timeline, multiple authoritative news sources (CNBC, Reuters, CNN, The Globe and Mail) corroborate that a war with Iran began around March 1, 2026, and triggered a massive sell-off in the S&P 500. While the index saw a brief recovery on March 9, the cumulative loss by March 13, 2026, is widely reported to be in the trillions, with the $2 trillion figure being a consistent estimate of the market capitalization erased during this period of high volatility and surging oil prices.
