The Spanish index has accumulated a 14% increase in 2026 and is at its highest in the last decade. A victory for the Spanish team in the World Cup could be the catalyst to reach the 20,000 point mark.
The Ibex 35 has decisively broken its annual highs and is approaching the psychological barrier of 20,000 points. The Spanish index has accumulated an increase of nearly 14% so far in 2026, supported by solid corporate fundamentals and a favourable macroeconomic context. Tonight's World Cup final could be the definitive push to reach that mark.
The historical impact of World Cups on stock markets
The analysis team at XTB has prepared a report that dissects the behaviour of the markets in champion countries during this century. The results show that, in the short term, the effect is moderate: since 2002, the main index of the winning country has barely advanced by an average of 0.12% in the first session following the final.
However, there are notable positive examples. Following Argentina's victory in 2022, the Buenos Aires stock exchange rose by 2.34%; Frankfurt's by 1.21% after Germany's triumph in 2014; and Milan advanced by 0.42% after Italy's win in 2006. In contrast, the CAC 40 fell by 0.37% after France's victory and the Ibovespa dropped by 2.21% after Brazil's.
In Spain's case, following the historic win in South Africa 2010, the Ibex 35 recorded a decline of 0.68% the next day. But that macroeconomic context was very adverse, with the risk premium soaring. Now the situation is radically different.
The Ibex 35 doubles its value since 2023
When analysing the perspective over a one-year horizon, the average increase of champion countries reaches a solid 9.8%, excluding the inflationary distortion of Argentina in 2022. Moreover, the sponsoring firms linked to success, such as Adidas (which rose by 35.2% in the year following 2010), Heineken (+19.6%) or Iberdrola (+15.1%), significantly outperformed the market.
The current Ibex 35 is in good health. It was in November 2023 that it regained 10,000 points for the first time since the pandemic; since then, the market value has nearly doubled, surpassing records from the pre-2008 crisis era. The banking sector leads the gains thanks to record intermediation margins, while Inditex sets valuation records and energy companies remain strong.
Analysts at Bankinter insist that the Ibex "is trading below its true value", while Renta 4 highlights the robustness of earnings per share growth, ruling out any kind of bubble.
What it means for investors
For investors, a possible victory for the Spanish team would not only be a source of sporting pride but could also act as a psychological catalyst for the Ibex 35 to reach 20,000 points. Although the immediate effect is usually moderate, the historical data over twelve months is positive, with an average increase of 9.8%.
Investors should note that the current context is very different from that of 2010: the risk premium is low, corporate profits are growing, and the market shows no signs of overvaluation. A victory tonight could be the push that consolidates the upward trend.
The match is tonight at 21:00 hours (peninsular time). If Spain is crowned champion, the Ibex 35 will open with anticipation tomorrow. In the long term, the fundamentals suggest that 20,000 points are just a matter of time.
