Global stock markets experienced a rebound on Wednesday, March 4, 2026, following two days of declines triggered by escalating tensions in the Middle East. The catalyst for the initial downturn was a joint military operation conducted by the United States and Israel against targets in Iran, a move that sent shockwaves through international markets and raised concerns about regional stability and potential disruptions to global energy supplies. While anxieties remain high, a degree of calm returned as investors assessed the immediate fallout and considered potential mitigating factors, including diplomatic efforts and assurances regarding key shipping lanes.
The initial reaction to the military action saw significant losses across European bourses. Still, Wednesday brought a shift in sentiment, with major indices posting gains. The Ibex 35, Spain’s benchmark stock index, led the recovery, closing with a 2.5% increase, bolstered by expectations of support from the European Union in the face of potential trade repercussions from the United States. This resilience came despite threats from U.S. President Donald Trump to impose commercial sanctions on Spain for its opposition to the use of Spanish military bases for operations related to the conflict in Iran. The broader European market followed suit, with indices in London, Paris, and Frankfurt also registering positive gains.
Market Response and Sectoral Impacts
The energy sector remained a focal point for investors. While oil prices initially surged following the attacks, they began to moderate on Wednesday as the United States signaled its intention to provide guarantees for maritime traffic through the Strait of Hormuz, a critical waterway for global oil shipments. According to Reuters, approximately 20% of the world’s oil consumption passes through this strategic chokepoint. Reuters reported in April 2024 that a complete disruption of oil flow through the Strait of Hormuz could have devastating consequences for the global economy.
Beyond energy, financial institutions with significant exposure to the Middle East also experienced volatility. Banks like Santander and BBVA, both major players in the Spanish market, saw their share prices fluctuate as investors weighed the potential risks associated with the conflict. Companies with substantial operations in the region, such as Repsol, Endesa, and Telefónica, also issued warnings about the potential impact on their businesses, citing concerns about supply chain disruptions, inflationary pressures, and broader macroeconomic instability. Repsol, in its latest annual report, highlighted the ongoing uncertainty surrounding geopolitical tensions and potential volatility in key exporting countries like Venezuela, Iran, and Russia. Repsol’s annual reports are publicly available on their investor relations website.
The Ibex 35’s Performance and Key Gainers
The Ibex 35’s strong performance on Wednesday was driven by gains in several key sectors. Acciona led the charge, with its share price rising by 5.14%, followed by Indra (up 4.98%), IAG (up 4.84%), and Amadeus (up 3.68%). However, not all stocks participated in the rally. Repsol experienced a decline of 1.88%, while Enagás and Rovi also closed in negative territory, falling by 0.72% and 0.12%, respectively. Analysts at Renta 4 noted the positive impact of the U.S. Commitment to securing maritime traffic and the easing of oil prices, but cautioned that the situation remained fluid and subject to rapid change.

Trump’s Trade Threats and EU Response
Adding another layer of complexity to the situation, President Trump threatened to impose trade sanctions on Spain in retaliation for its refusal to allow the United States to use its military bases for the operation against Iran. This move sparked concerns about a potential escalation of tensions between the U.S. And its European allies. However, the European Union signaled its intention to provide support to Spain, potentially mitigating the impact of any U.S. Sanctions. The EU’s stance reflects a broader effort to maintain diplomatic channels and de-escalate the conflict. According to El Mundo, the EU is prepared to offer Spain assistance in navigating the trade dispute with the United States. El Mundo’s website provides ongoing coverage of the EU’s response.
The potential for a trade war between the U.S. And Spain is particularly concerning given the economic ties between the two countries. The United States is currently Spain’s primary source of natural gas imports and a major export market for Spanish goods. Any disruption to these trade flows could have significant consequences for the Spanish economy. The U.S. Energy Information Administration (EIA) provides detailed data on U.S. Natural gas exports. The EIA website offers comprehensive energy statistics and analysis.
Broader Economic Implications
The conflict in Iran and the associated geopolitical risks are contributing to a climate of uncertainty in global markets. Investors are closely monitoring developments in the region, assessing the potential impact on oil prices, inflation, and economic growth. The International Monetary Fund (IMF) has warned that the conflict could exacerbate existing inflationary pressures and sluggish down global economic recovery. The IMF’s website provides regular updates on the global economic outlook.
The situation is further complicated by the ongoing war in Ukraine and other geopolitical hotspots. These factors are creating a challenging environment for businesses and investors, and are likely to continue to weigh on market sentiment in the near term. The World Bank also highlights the interconnectedness of global risks and the potential for spillover effects. The World Bank’s website offers insights into global development challenges.
