On 28 September, Christine Lagarde told the European Parliament's Economic and Monetary Affairs Committee that Europe's housing crisis stems mainly from a gap between supply and demand. The ECB president spoke in Brussels as lawmakers examined how monetary policy affects households seeking a stable home.
Her argument does not dismiss borrowing costs. Higher rates make mortgages more expensive. Lagarde said ECB decisions eventually feed through to financing costs, but rejected the idea that they alone explain the wider crisis.
The ECB raised its three basic interest rates by 25 basis points on 10 September 2026. The deposit rate reached 2.50%. The refinancing rate rose to 2.65%, while the marginal lending rate reached 2.90%.
Lagarde also addressed the human cost. She said she felt sad when people lost their homes. In recent days, events in Spain had drawn particular attention from her. Her point extended beyond one country: housing is a central concern for people across Europe.
The latest rate decision offers one specific measure. Lagarde said the 25-basis-point increase adopted in June had lifted household mortgage costs by 0.01%, based on the ECB's observations. She presented the figure as evidence that the immediate effect of the latest move was small compared with the supply problem.
Rates still matter. Monetary tightening can raise financing costs and make it harder for households to buy or keep a home. Lower borrowing costs alone would not create the missing homes or correct the imbalance across many European countries.
The official ECB account also said longer-term interest rates had risen noticeably. They were expected to restrain growth and inflation more than the September forecast had projected. Financial conditions have tightened.
Euro-area data show why construction remains central to the debate. Housing investment fell by 1.3% quarter on quarter in the second quarter of 2026, following a 1.9% decline in the previous quarter. The ECB expects a gradual recovery, but recent figures show tighter financial conditions weighing on building activity.
In Spain, the problem has become a major social and political issue. Bank of Spain estimates put the shortage at around 700,000 homes. Other Spanish assessments put the accumulated deficit at 755,000 units. Assessments cited by AFP and local reporting warn that the deficit could grow by a further 300,000 homes from 2026 to 2028 if construction fails to catch up with demand.
Large demonstrations in Madrid called for stronger tenant protection and a ban on evictions without alternative accommodation. The protests help explain why Lagarde linked monetary policy to people losing their homes and growing housing insecurity.
The Bank of Spain has called the housing problem a serious economic and social challenge. So far, it has not identified the issue as a threat to financial-system stability. That distinction lets central banks discuss housing affordability as a major public concern without calling it a banking crisis.
The basic risks stem from weak construction and limited supply, which widen the gap between demand and available homes. Officials had no quick fix.
Both facts can be true at once. Higher rates can raise mortgage costs for households. The wider housing crisis can still stem mainly from problems that interest rates cannot solve.
Reuters reported that Lagarde continued to consider measured ECB rate increases appropriate for controlling inflation. The Central Bank's own material also acknowledged that higher long-term yields were already tightening financial conditions. Her position puts the basic weight on the supply problem while recognizing the financial pressure caused by rates.
Lagarde's statement does not suggest that ECB policy has no effect on housing. Rather, the Central Bank does not see its latest rate increases as the crisis's basic cause. For households in Spain and elsewhere in Europe, mortgage costs remain part of the burden. Finding an affordable and secure home still depends on a supply-and-demand problem that the ECB cannot resolve through interest rates alone.
