March 31 (Reuters) - U.S. stock index futures gained on Tuesday, as markets welcomed a report signaling a potential de-escalation in the Middle East conflict that has set the S&P 500 and the Dow for their biggest monthly decline in years.
The Wall Street Journal on Monday reported that U.S. President Donald Trump told aides he was willing to end the military campaign against Iran even if the Strait of Hormuz remained largely closed.
The report soothed some market nerves after a month-long conflict that has battered global markets and left the S&P 500 and the Dow on track for their biggest monthly falls since September 2022.
Oil prices were volatile on Tuesday, but were headed for a record monthly gain. The S&P 500 energy index .SPNY has gained over 11% so far in March, the only sector set to end the month in the positive territory.
The Dow and the Nasdaq last week ended 10% below their record high closes, confirming a correction. The small-cap Russell 2000 .RUT confirmed it earlier this month.
Isabella Mateos Y Lago, an economist at BNP Paribas, said investors were not expecting the war to cause meaningful damage to growth, with many analysts sticking to their pre-war end-2026 U.S. index targets, and making little downgrades to earnings forecasts, as cash holdings remained below Trump's tariff announcement levels.
"As long as the possibility of scenarios that inflict only manageable growth costs persists, it is preferable that financial markets do not amplify headwinds from higher energy prices and more hawkish central banks."
At 05:08 a.m. ET, Dow E-minis YMcv1 were up 417 points, or 0.92%, S&P 500 E-minis EScv1 were up 57 points, or 0.89% and Nasdaq 100 E-minis NQcv1 were up 194.25 points, or 0.84%.
