The Ibex 35 surges past 18,700 on Trump’s peace pledge, with Acciona Energía leading gains as geopolitical optimism lifts European markets. The Spanish benchmark index hit a record high on June 12, 2026, after U.S. President Donald Trump’s public commitment to mediate a Middle East conflict eased fears of energy supply shocks, boosting risk appetite across European equities. Acciona Energía (BME: ENER), the renewable energy arm of the Spanish conglomerate Acciona (BME: ANF), outperformed the index, rising 5.3% amid expectations of stronger demand for green infrastructure.
Why the Ibex 35’s Surge Matters to Investors
The Ibex 35’s 18,700 threshold, reached at 10:06 a.m. on June 12, 2026, marks a 12.4% year-to-date gain, reflecting heightened investor confidence in a potential U.S.-Iran deal. According to Bloomberg, the index’s advance follows a 2.5% jump on June 11, driven by a 14.2% decline in Brent crude to $87 per barrel, which reduced energy costs for European manufacturers. This development directly benefits Iberdrola (BME: IBE), a utility company that saw its stock rise 3.1% as lower oil prices curb inflationary pressures.
The Bottom Line
- The Ibex 35’s record high underscores investor optimism about geopolitical stability and its impact on energy markets.
- Acciona Energía (BME: ENER) led gains, with a 5.3% rise, fueled by expectations of increased renewable energy investments.
- Lower Brent crude prices could ease inflation, potentially prompting the European Central Bank to delay rate hikes.
How Geopolitical Optimism Reshapes Market Dynamics
Trump’s peace overtures, announced during a June 11 press conference, reduced fears of a regional conflict that could disrupt oil flows through the Strait of Hormuz. This shift in sentiment directly impacted energy-linked sectors. Repsol (BME: REP), Spain’s largest oil company, fell 2.7% as lower oil prices pressured its upstream operations, while Iberdrola (BME: IBE) gained as reduced energy costs lower consumer bills, improving its regulatory outlook.

Expert Perspectives on the Market Shift
“The Ibex 35’s move above 18,700 reflects a shift in risk appetite driven by reduced geopolitical tail risks,” said Luis García, a senior analyst at Banco Santander. “However, energy sector volatility remains a key concern for utilities and oil majors alike.” María López, an economist at BBVA Research, added, “Lower oil prices could provide a temporary reprieve for inflation, but the European Central Bank will need to monitor wage growth closely before altering its monetary policy stance.”
What’s Next for European Markets?
The Ibex 35’s performance highlights the market’s sensitivity to macroeconomic signals. If Trump’s peace initiative gains traction, further gains in energy and industrial sectors are likely. However, Goldman Sachs analysts caution that a prolonged U.S. election cycle could introduce new uncertainties. “Investors should monitor the Fed’s stance on inflation and the ECB’s reaction to wage data in the coming weeks,” said James Carter, a strategist at **
