Wall Street in Rally Mode: How an Iran War End Affects Your Stocks

US President Donald Trump signaled at the end of March 2026 according to a report by the Wall Street Journal his willingness to end the military conflict with Iran. When asked whether he would also end the US military deployment without reopening the strategically important Strait of Hormuz, Trump stated he did not give it any thought. The statement triggered immediate market reactions and fueled speculation about an imminent end to the war.

The conflict was triggered by an internationally controversial preemptive strike by Israel and the US on the Iranian regime. This was followed by Iranian retaliatory attacks on various states in the Persian Gulf as well as on Israel and Cyprus, which caused considerable damage to regional energy infrastructure.

Energy Markets Under Pressure: Infrastructure in the Persian Gulf Damaged

The Iranian attacks struck at the heart of global energy supply. According to reports from the region, 17 percent of Qatar's liquefied natural gas export capacities were shut down – a significant share of global LNG trade. Natural gas facilities in the United Arab Emirates as well as refineries in Saudi Arabia and Kuwait suffered damage.

The immediate consequence was a rise in oil and gas prices. Nevertheless, financial markets have remained relatively calm so far. Investors apparently assume that the conflict will not escalate and that energy supply can be restored in the medium term. This expectation has shaped market sentiment for weeks and dampens panic selling.

European Stock Markets: EuroStoxx 50 Rises Despite Headwinds

European stock markets reacted to prospects of war ending with recovery moves. The EuroStoxx 50 rose 0.6 percent to 5,775 points. Despite initial pressures from rising energy prices, a recovery occurred after positive signals arrived from Wall Street.

The DAX also showed stability despite geopolitical tensions. Noteworthy is the reaction of individual stocks: Rheinmetall shares, for example, turned from initial losses into gains. Defense stocks had benefited from the conflict at the beginning of 2026, but now show mixed reactions to the prospect of a war ending.

Wall Street with Mixed Signals: Dow Jones in the Black

US stock markets presented themselves as volatile in March 2026. The Dow Jones Industrial Average managed to stay in positive territory with a meager gain of 0.11 percent and closed at 45,216.14 points. NASDAQ100 and S&P500, on the other hand, recorded losses on several consecutive trading days.

According to CNN Business, the market rallied on the hope that the policy shift reported by the Wall Street Journal provides concrete signs of an imminent end to the conflict. However, March's volatility shows how uncertain investors continue to act.

What Does a War End Mean for Different Asset Classes?

An end to the Iran conflict would have different effects on various sectors and asset classes. Energy stocks could come under pressure if the damaged infrastructure in the Persian Gulf is restored and supply increases. At the same time, falling energy prices would ease the burden on companies with high energy consumption – such as those from the chemical, transport, and manufacturing industries.

Defense stocks, which gained new momentum in early 2026, could lose attractiveness in the event of a lasting peace settlement. However, history shows that geopolitical tensions rarely disappear completely and defense spending by Western states is likely to remain at elevated levels in the medium term.

For European investors, the development of energy prices is particularly relevant. The European economy, which is more dependent on energy imports than the US, would benefit disproportionately from falling oil and gas prices. This could particularly boost energy-intensive sectors in Germany and Austria.

Historical Context: How Markets React to War Endings

A look at stock market history shows that equity markets often begin to rise before the official end of war. Once investors consider de-escalation probable, risk positions are rebuilt. Current market sentiment suggests that this process has already begun.

At the same time, investors face the question of alternatives. With negative real yields on safe bonds and money market accounts, stocks remain one of the few ways to achieve real wealth growth. This structural demand supports markets even in volatile phases.

Outlook: Uncertainty Remains Despite Signals of Relief

Trump's announcement is viewed by markets as a positive signal, but uncertainty remains. It is unclear what concrete steps will follow and whether the Iranian regime will agree to an agreement. The Strait of Hormuz – one of the world's most important shipping routes for oil tankers – remains a critical factor for energy security.

For investors in the DACH region, the current situation means: vigilance is warranted, but panic is uncalled for. European indices show stability, and an end to the conflict would particularly benefit energy-intensive sectors. At the same time, broadly diversified portfolios should remain the foundation of any investment strategy to be resilient even to renewed geopolitical shocks.

The coming weeks will show whether the signals of relief from Washington translate into concrete peace negotiations. Until then, volatility in markets is likely to remain elevated – with opportunities for disciplined investors, but also risks for short-term oriented traders.
