House prices hit fresh highs in Spain and Portugal. What's behind it?

House prices in Spain and Portugal have reached record levels, signaling a significant shift in the real estate landscape of these two Iberian nations. The surge in property values has made buying a home increasingly difficult for many residents, prompting both governments to scrutinize their housing markets closely due to concerns about affordability. Despite this, neither country has implemented sweeping lending restrictions aimed at curbing the trend. According to data from Reuters, house prices in Spain increased by 12.9% compared to the same period last year during the first quarter of 2026. Meanwhile, Portugal witnessed an even steeper rise of 17.8%, marking the highest annual increase within the eurozone. These figures highlight a rapidly evolving situation in the housing sector, influenced by multiple factors including robust demand, constrained housing supply, economic expansion, and increasing immigration flows. Notably, mortgage lending has continued to grow despite elevated borrowing costs, indicating a persistent demand for housing finance. Spanish banks have notably expanded their lending portfolios, with total outstanding housing loans amounting to approximately €496 billion. Data from the Bank of Spain reveals that an increasing proportion of new loans are being issued under high loan-to-value ratios. This trend has sparked discussions regarding the need for enhanced oversight of lending practices. The International Monetary Fund (IMF) previously advised Spain to contemplate implementing formal loan-to-value limitations to mitigate potential financial risks. However, Spanish officials believe that imposing stricter borrowing constraints might further hinder the ability of first-time and younger buyers to access the housing market. In contrast, Portugal’s central bank has opted for a more assertive stance. Recently, the institution lowered the maximum debt service-to-income ratio for new borrowers from 50% to 45%, effectively tightening borrowing conditions for individuals seeking home loans. Both countries have historically experienced housing booms prior to the 2008 global financial crisis. Nevertheless, current government representatives have refuted comparisons suggesting a repeat of past patterns. Adjusted for inflation, Spanish house prices still fall short of their 2007 peak, and mortgage lending standards today are perceived as more resilient than they were prior to the crisis. A greater percentage of borrowers now possess fixed-rate mortgages, thereby lessening families' vulnerability to fluctuating interest rates. Economists consulted by Reuters suggest that the present housing boom is primarily fueled by enduring supply shortages rather than unchecked credit expansion. In Spain, the rate of new housing construction has struggled to meet the rising demand, perpetuating higher prices. Similarly, in Portugal, housing supply has consistently fallen short of demand, sustaining price increases even amidst tighter monetary policies. Consequently, regulators have adopted a measured strategy, aiming to balance financial stability considerations against deteriorating housing affordability. Authorities in both nations continue to observe mortgage lending and household debt levels carefully. However, there appears to be minimal inclination towards adopting stringent macroprudential measures at this time. Policymakers aim to prevent unnecessary barriers to housing finance for financially sound borrowers while addressing the challenges posed by the current housing market dynamics. The interplay between these competing priorities will likely shape future regulatory actions and influence the trajectory of the housing markets in Spain and Portugal.
