War Between Iran, Interest Rates and the Spanish Real Estate Market: How It Will Impact Investment in 2026

Geopolitical Conflict Fuels Financial Uncertainty and Reinforces the Appeal of Prime Real Estate

The escalating tensions between Iran and the West are creating renewed uncertainty across international markets. Although a global energy supply crisis is not currently expected, the conflict has introduced a significant risk premium on oil prices, inflation and interest rates across Europe.

Against this backdrop, the Spanish real estate market — particularly the luxury residential segment — continues to strengthen its position as one of the most attractive safe-haven assets for both domestic and international investors.

How the Iran Conflict Is Affecting the Euribor and Mortgages

One of the main consequences of the conflict has been increased volatility in oil prices. Brent crude has recently surpassed $100 per barrel, trading within an approximate range of $94 to $119 per barrel.

This rise in energy costs has a direct impact on:

• Inflation across the Eurozone
• The European Central Bank’s (ECB) monetary policy
• Mortgage financing costs
• Access to real estate credit

At present, the ECB maintains official interest rates at 2%, although markets are already pricing in potential increases to 2.25%–2.50% should inflation continue to rise.

At the same time, the Euribor continues to show an upward trend and has already reached its highest levels in the past 16 months, approaching 2.75%–3%.

Inflation in Europe: The ECB’s Main Concern

Eurozone inflation reached 3% in April 2026, its highest level since September 2023.

Rising energy prices could trigger:

• Further inflationary pressures
• More expensive mortgages
• Tighter lending conditions
• Reduced purchasing power for the middle class

Nevertheless, the ECB is currently maintaining a cautious stance, considering that part of the impact may prove temporary.

Spanish Real Estate Market: Resilience and Strength in the Prime Segment

Despite the geopolitical environment, Spain’s luxury residential market continues to benefit from strong and highly international demand.

The report highlights that the prime segment is expected to remain one of the most dynamic and resilient sectors in 2026, further consolidating its status as a safe-haven asset amid global uncertainty.

Several factors explain this strength:

• Limited supply of premium properties
• Strong international demand
• Spain’s legal security and stability
• Attractive comparative returns versus other European markets
• Continued interest from high-liquidity buyers

Madrid and Barcelona Among Europe’s Most Attractive Cities for Investment

Spain continues to position itself as one of Europe’s most competitive real estate destinations.

Madrid ranks among the leading European cities for both overall real estate investment and luxury residential property, while Barcelona remains firmly within the European Top 10.

The areas expected to show the strongest momentum in 2026 include:

Madrid: Salamanca, Chamberí and Justicia
Barcelona: Eixample and Zona Alta
Costa del Sol: Marbella, Estepona and Nueva Andalucía
Balearic Islands: Ibiza and Mallorca

Markets such as Valencia, Alicante and San Sebastián are also gaining prominence thanks to their growing international appeal.

Real Estate Investment in 2026: Market Outlook

Forecasts point towards a still-active market, although performance is expected to vary across different segments.

What Could Happen in 2026

• Moderate price increases of 6%–10% in premium areas
• Greater pressure on leveraged buyers
• Increased demand for mixed-rate and fixed-rate mortgages
• Limited corrections in less liquid markets
• Continued resilience in prime and ultra-prime assets

The study also estimates that Spain could exceed 700,000 real estate transactions, approaching record figures not seen since 2007.

International Demand Will Continue to Drive the Luxury Market

One of the most significant trends is the growing weight of foreign buyers.

Currently, 92% of high-end transactions are driven by international demand, particularly from buyers in Latin America, the United States, the United Kingdom, Germany, France and Sweden.

In addition, approximately 40% of international buyers finance their purchases in Spain in order to benefit from mortgage rates that remain comparatively competitive versus those in their home countries.

Is It a Good Time to Buy Property in Spain?

Although financing conditions may tighten slightly over the coming months, Spain continues to offer attractive opportunities for buyers and investors, especially within the premium segment.

Experts believe that:

• The prime market carries a low risk of correction
• International demand will remain strong
• Limited supply will continue to support prices
• Real estate will continue to act as a safe-haven asset

For wealth-preservation buyers and international investors, financing the purchase of property in Spain remains an efficient strategy for optimising capital and returns.

Conclusion

The conflict between Iran and the West is increasing global financial volatility and could generate further inflationary pressures across Europe. However, the Spanish real estate market — particularly the luxury residential sector — continues to demonstrate a high degree of resilience.

Madrid, Barcelona, the Costa del Sol and the Balearic Islands are expected to remain at the forefront of international real estate investment in 2026, while the prime segment further consolidates its position as one of the strongest asset classes amid economic and geopolitical uncertainty.
