The Iberian Peninsula has become one of Europe’s strongest-performing property markets, driven by high demand, limited housing supply and resilient economic growth. According to first-quarter figures, house prices rose by 12.9 percent year-on-year in Spain and by 17.8 percent in Portugal, the highest annual increase recorded anywhere in the European Union.

Despite growing concerns over affordability, regulators in both countries are taking a measured approach rather than introducing sweeping restrictions on lending.

Portugal Tightens Mortgage Rules

Portugal’s central bank has already introduced one precautionary measure by reducing the maximum debt service-to-income ratio for new mortgage borrowers from 50 percent to 45 percent. The change is designed to help ensure buyers can comfortably manage repayments if economic conditions change.

Officials believe this targeted adjustment is sufficient for now, with current lending standards remaining significantly stronger than those seen before the global financial crisis.

Spain Chooses a Cautious Approach

In Spain, regulators are also watching the market closely as mortgage lending continues to grow. Competition among major banks has intensified as demand for home loans increases, supported by a strong economy and continued population growth through immigration.

While the International Monetary Fund has suggested Spain consider introducing limits on loan-to-value ratios, the Bank of Spain has so far decided against additional restrictions, warning that tighter lending rules could make it even harder for younger buyers to enter the housing market.

Supply is still the Biggest Challenge

Analysts say today’s market differs from previous housing booms because rising prices are being driven primarily by a shortage of available homes rather than excessive borrowing.

Higher-income households continue to account for much of the current demand, while strict lending standards and the widespread use of fixed-rate mortgages have reduced financial risks compared with the years leading up to 2008.

Housing affordability, however, remains a growing concern across both countries as supply struggles to keep pace with demand.

No Immediate Intervention Expected

Although regulators acknowledge signs of overheating, economists believe neither Spain nor Portugal is likely to introduce major market intervention in the near future.

Instead, authorities are expected to continue closely monitoring lending activity and house prices while balancing the need to maintain financial stability with improving access to housing for first-time buyers.
