S&P 500 Rebounds With Iran War Ceasefire, Falling Oil Prices

Investors reacted positively to the after the market close news of a ceasefire between the Iran war combatants on 7 April 2026. The S&P 500 () (Index: SPX) bounced up 2.5% on the news the following day before proceeding to increase its gains in the remainder of the trading week. By the time the market closed on Friday, 10 April 2026, the index stood at 6,816.89, up a little under 3.6% from its previous week's level.

The news of the ceasefire had an immediate effect on oil prices. Crude oil futures (CL1:COM) had peaked at $117.62 per barrel earlier on 7 April 2026, but plunged at low as $94.62 after the announcement. Crude oil futures went on to spend most the rest of week in the mid-to-upper $90 per barrel range.

The drop in oil prices helped shape expectations for how the Federal Reserve will set interest rates in the U.S. While the CME Group's FedWatch Tool continues to foresee no interest rate changes through the end of 2026, it does see a growing chance for a quarter point rate cut in 2027, with the most likely timing being near the end of 2027-Q2, three months earlier than projected in the preceding week.

In this latest update of the alternative futures chart, the S&P 500 is about four percent below the central trend line of the redzone forecast range we added to the chart after Friday, 20 February 2026.

We had added the redzone forecast range to the chart, fully shown in this version, to compensate for the year-old echoes of two major volatility events, which arise from the dividend futures-based model's use of historical stock prices as the base reference points for its projections of the future. In this case, that was the echoes from February 2025's DeepSeek AI shock and President Trump's April 2025's "Liberation Day" tariff announcements. That redzone forecast range turned out to be ideally suited to use as a counterfactual to measure the impact of the Iran war geopolitical event on U.S. stock prices by indicating where they would reasonably have been in the absence of that event.

The rest is just keeping up with how the flow of news related to the Iran war's developments. Here are the week's market moving headlines:
