Iran Conflict Over? Wall Street Rises on War-End Speculation

US stock markets recorded a strong recovery rally at midday on March 31, 2026: The Dow Jones Industrial Average rose 2.1 percent or nearly 1,000 points at times, according to market data. The trigger for the gains was reports of possible peace negotiations in the Iran conflict, which could signal an easing of the geopolitical situation.

Broad market gains across all indices

The gains are spread across all major US indices. The technology-heavy Nasdaq rose 3.3 percent, the S&P 500 gained 2.5 percent. Earlier on March 25, 2026, the Dow Jones had reacted with a plus of 305.43 points or 0.7 percent to 46,429.49 points. The S&P 500 gained 0.5 percent to 6,591.90 points, the Nasdaq 0.8 percent to 21,929.83 points.

The weekly balance at the end of March was correspondingly positive: The Dow Jones recorded a weekly increase of 852.02 points or 1.9 percent. The smaller Russell 2000 Index, which tracks mid-cap US companies, also benefited with a weekly gain of 1.2 percent to 2,536.38 points.

Relief rally following peace reports

Market observers speak of a classic relief rally. The Wall Street Journal reported signals from both Iran and the United States indicating a willingness to end hostilities. US President Trump signaled his intention to end the Iran war and spoke of significant progress in peace negotiations. He suggested that he was willing to end the conflict without opening the Strait of Hormuz.

The Strait of Hormuz is one of the world's most important maritime trade routes for oil transport. A blockade or disruption of this waterway typically drives oil prices and thus inflation expectations upward. The prospect of a conflict resolution without further escalation in this strategic region is therefore viewed positively by the markets.

Oil prices decline

Parallel to stock market gains, oil prices are falling. Declining energy costs have a positive effect on inflation expectations and ease the burden on companies with high energy costs. The combination of geopolitical easing and declining commodity prices creates a more favorable environment for riskier investments such as stocks.

Year-to-date balance remains negative

Despite the recent recovery, the Dow Jones remains in negative territory for 2026. At the time of the rally, the index was trading with a decline of 1,633.80 points or 3.4 percent compared with the prior year. However, according to analysts, the current gains suggest a possible trend reversal, should the geopolitical situation continue to ease.

Cautious market sentiment remains

Whether the hopes for peace will actually hold remains to be seen. While reports of a US plan for a war pause became known, Iran initially rejected the proposal and fighting in the Middle East continued. Markets are currently pricing in an optimistic scenario but remain vulnerable to setbacks should negotiations stall or fail.

On the trading day following the major rally of March 31, US indices posted further gains: the Dow Jones and S&P 500 each rose 0.6 percent. This development shows that market participants initially expect a sustainable easing of tensions.

European markets follow

European stock markets also reacted positively to developments. The hope for a swift end to the Iran conflict supported prices, as European companies had also suffered from high energy prices and geopolitical uncertainty. Futures on the major US indices were already trading in the plus before market open, underscoring the positive mood.
