The Spanish index closed at 19,104.3 points, its lowest level since June 15, marking three consecutive days of losses.
The IBEX 35 suffered a plunge of 2.73% on Wednesday, its largest single-day drop since March 3, when the index fell by 4.55% amid escalating tensions between the United States and Israel with Iran. The main index of the Spanish stock market closed at 19,104.3 points, its lowest level since June 15, and lost more than 500 points during the session.
Geopolitical tensions and Trump's threats weigh on the market
The day was marked by uncertainty due to the new confrontation between the United States and Iran, after US President Donald Trump declared during the NATO meeting in Turkey that the peace agreement with Iran was over. Additionally, Trump stated that he does not want to maintain trade relations with Spain, considering it a "terrible" partner. These statements exacerbated the climate of nervousness in the markets.
"The peace agreement with Iran is over," Trump stated during the NATO summit.
The Spanish risk premium also suffered: it increased by almost 2% to stand at 49.3 basis points, reflecting a greater perception of risk regarding Spanish debt.
Only four stocks remain in positive territory
In a sea of losses, only four companies in the IBEX 35 managed to close in positive territory. Repsol led the gains with an increase of 5.13%, followed by Naturgy (+1.24%), Endesa (+0.26%) and Enagás (+0.24%). Iberdrola ended unchanged. In contrast, the largest declines were for Amadeus (-5.44%), Banco Santander (-5.06%) and Acerinox (-4.99%).
The energy sector benefited from the rise in oil prices amid tensions in the Middle East, which explains the bullish behaviour of oil and gas companies. Conversely, stocks more exposed to tourism and international trade suffered significant losses.
For individual investors, this drop represents an opportunity to review portfolios, especially in defensive sectors like energy, which have shown resilience. Experts recommend staying calm and not making hasty decisions, as volatility may continue in the coming days. The evolution of diplomatic negotiations between the United States and Iran will be key to determining whether the market regains confidence.
The IBEX 35 has accumulated a decline of nearly 5% so far this year, weighed down by geopolitical uncertainty and trade tensions. The next session will be marked by the publication of macroeconomic data in Europe and any statements that may arise from the NATO summit.
