05:05 PM EDT, 04/21/2026 (MT Newswires) -- US equity indexes fell on Tuesday, while crude oil futures jumped as President Donald Trump reportedly extended the Iran ceasefire deal until Tehran submits a "unified proposal" to end the war.

The Nasdaq Composite fell 0.3% to 24,334.81, with the S&P 500 down 0.6% to 7,064.01 and the Dow Jones Industrial Average lower by 0.6% to 49,149.38. All three gauges traded higher earlier in the session. All sectors except energy fell. Real estate, utilities, and industrials led the decliners.

Trump said he has extended the ceasefire until Tehran submits a proposal to end the conflict permanently, CNN reported late Tuesday. The ceasefire was due to expire on Wednesday evening ET. Trump said he will continue the US blockade of Iranian ports.

Trump said the extension was warranted as Tehran's government is "seriously fractured," CNBC reported.

Vice President JD Vance was set to leave Tuesday morning for Pakistan, the expected location for the US-Iran talks, but his trip has been put on hold, CNN reported. The US blockade of the Strait of Hormuz has contributed to the ongoing uncertainty surrounding a second round of talks, CNN cited sources as saying.
