Personal loans reach 23 percent of lowest-wealth household debt
Banco de España Governor José Luis Escrivá emphasized the necessity of micro-level wealth data for economic and macroprudential policy. Speaking in Madrid on September 4, 2026, he noted that personal loans now make up 23 percent of total debt among the least wealthy households.
The vulnerability beneath the surface
Spanish median household debt declined from around €55,000 in 2014 to approximately €30,000 in 2024, while the overall proportion of indebted households remained stable.
However, aggregate figures obscure significant structural shifts across the wealth distribution.
Personal loans have gained substantial weight over mortgages, now representing roughly 23 percent of total debt for households in the lowest net wealth quartile—an increase of 17 percentage points over the decade.
Governor José Luis Escrivá cautioned that assessing systemic vulnerabilities or implementing macroprudential tools, such as loan-to-value (LTV) or loan-service-to-income (LSTI) limits, requires granular microdata to avoid generating adverse distributional outcomes.
Breaking down administrative silos
The Survey of Household Finances (EFF), pioneered by Olympia Bover, served as the blueprint for the Eurosystem's Household Finance and Consumption Survey by solving oversampling challenges at the top of the wealth distribution.
Escrivá called on public administrations to treat administrative records as a public good and eliminate resistance to data sharing.
He emphasized that emerging artificial intelligence tools require authentic survey data rather than synthetic inputs to detect nonlinear patterns.
A warning against blunt instruments
Escrivá rightly challenges the reliance on blunt aggregate metrics in macroprudential policy.
His evidence on concentrated consumer debt exposes the genuine risk of imposing blanket borrower limits without distributional data.
Public agencies hoarding administrative records must open up, as analytical blind spots carry severe economic costs.
