U.S. stocks and oil prices saw volatile trading on Monday as investors grappled with uncertainty surrounding the ongoing conflict between the United States and Iran. The S&P 500 edged up 0.3% while oil prices seesawed between gains and losses, with the benchmark U.S. crude rising 0.3% to $111.88 per barrel. The volatility comes ahead of a deadline set by President Trump to bomb Iranian power plants if the country does not open the Strait of Hormuz, a critical global oil chokepoint.

Why it matters

The conflict between the U.S. and Iran has already disrupted global energy markets, sending oil and gas prices soaring. A further escalation of the conflict, including potential attacks on Iranian infrastructure, could have severe economic consequences, particularly for countries more reliant on Middle Eastern oil exports. Investors are closely watching the situation for signs of how it may impact the broader economy and financial markets.

Fighting is continuing between the U.S. and Iran, including an Israeli attack on an Iranian petrochemical plant. Trump has set a deadline of Tuesday, April 9th, to bomb Iranian power plants if the country does not open the Strait of Hormuz, a key global oil chokepoint. Iran has rejected the latest ceasefire proposal, saying it wants a permanent end to the war. The uncertainty has led to volatile trading in U.S. stocks and oil prices, with the S&P 500 edging up 0.3% and benchmark U.S. crude rising 0.3% to $111.88 per barrel.
