The Ibex 35 has closed the week with a decline of 0.85%, settling below 19,700 points, affected by Donald Trump's threats to Spain at the NATO summit and the rise in oil prices due to the conflict in the Middle East.
Donald Trump's bluster at the NATO Summit has shaken the markets. The US president threatened to cut trade operations with Spain and suggested punitive actions over the level of investment in Defence by the Spanish government. The tension adds to the escalation in the Middle East, which has driven up oil prices and affects the normal development of the stock markets.
Ibex 35 loses 19,700 points
This week, the main Spanish index has fallen by 0.85%, closing below 19,700 points. The hardest hit came on Tuesday, with a drop of 2.73% driven by geopolitical tensions and rising crude prices. According to market sources, the situation recalls previous episodes where international tensions are used to adjust internal political moments in the United States.
Trump faces a cornering due to his decisions and the electoral disaster that the November legislative elections could entail. Uncertainty weighs on investors, who see how stock market normality is affected.
Acerinox and Merlin Properties stand out positively
On the positive side, Acerinox has led the gains with an increase of 4.77%, followed by Merlin Properties, which improved by 3.36%. However, the declines have been more pronounced: Endesa has lost 5.97% and Aena 3.28%. These movements reflect the volatility dominating the market.
Looking ahead to summer, if external events allow, the Ibex 35 could fluctuate around 22,000 points, according to analysts. Everything will depend on the decisions of central banks regarding interest rates. For now, uncertainty is the norm.
Defence sector in the spotlight
A relevant fact is the growth of Defence spending in Spain, which has increased by 63% between 2020 and 2025. Companies in the sector represent only 5% of the stock market, but Indra stands out with a profit increase of 57% by 2025. Investors should pay attention to the evolution of these companies, which could benefit from increased military spending.
For readers interested in the stock market, the recommendation is to closely follow geopolitical tensions and the decisions of the Federal Reserve and the European Central Bank. The summer looks volatile, and any news from the White House or the Middle East could move the indices.
