Did the 2012 Spanish law reform to protect mortgage debtors modify banks' lending behavior?

The 2007–2009 global financial crisis and the collapse of Spain’s housing bubble led to soaring unemployment, a surge in mortgage indebtedness, and unprecedented foreclosures and evictions. In response to social pressure, Spain enacted Royal Decree-Law 6/2012, introducing a Code of Good Practice to protect low-income mortgage debtors by enabling debt restructuring, possible debt reduction, and, as a last resort, payment in kind (dación en pago) with post-transfer social rent. The research question is whether this 2012 reform altered banks’ lending behavior. The paper posits that by raising protections and costs associated with high-risk lending, the Code could have induced banks to adjust credit supply, particularly restricting access for the very groups targeted for protection. The study uses regional panel data to empirically assess these effects.

The paper discusses arguments that enhanced debtor protection may reduce mortgage credit availability (Lacruz Mantecón, 2014) and prior evidence that the 2012 reform affected foreclosure dynamics (González-Val, 2021; 2022a). It references broader EU consumer over-indebtedness policies (Domurath et al., 2014), the transformation of Spain’s savings banks post-crisis (Goddard et al., 2009), and regulatory changes such as Basel III (CRD IV/CRR). It also notes jurisprudence on floor clauses (Spanish Supreme Court, 2013; CJEU, 2016) and related Spanish legal measures (RD-Law 27/2012; Law 1/2013). Overall, the literature suggests that legal and regulatory shifts, along with market conditions (e.g., Euribor decline), can influence mortgage supply, pricing, and borrower composition.

The study analyzes quarterly data for the 17 Spanish NUTS II regions from 2005 to 2020(Q1) (loans data from 2007), combining Land Registry and Notaries’ aggregates with INE and ministerial statistics. Outcomes include number of new mortgage loans (absolute and per 1000 inhabitants), real estate sales, and loan contract terms (interest rate, loan amount, monthly payment, monthly payment-to-wage cost). Controls: house prices (euros/m²), unemployment rate, and inflation rate. The empirical model is a dynamic panel: Y_it = α + ρY_it−1 + β1 ln(HP_it) + β2 UNEMP_it + β3 INF_it + Σ_k β_k d_k(Years since reform_it) + θ_i (region FE) + δ_t (year and quarter FE) + region-specific linear and quadratic time trends + u_it. The set of time dummies captures dynamic effects of the March 11, 2012 reform in bins (first 2 years; years 3–4; 5–6; 7–8). Estimation uses OLS with robust standard errors. The design addresses lack of a control group by extensive fixed effects and region-specific trends, controlling for pre-existing trends and concurrent macro-regulatory changes (e.g., Basel III implementation). Stationarity checks (Pesaran CADF) support comparability of pre- and post-crisis data. Results are reported for loans (2007–2020Q1) and other outcomes (2005–2020Q1).

• Access to credit: The reform reduced new mortgage lending. For ln(loans): first 2 years −0.030 (ns), years 3–4 −0.162***, years 5–6 −0.178***, years 7–8 −0.267***. For loans per 1000 inhabitants: first 2 years −0.105*, years 3–4 −0.384***, years 5–6 −0.451***, years 7–8 −0.658***. Lending contraction intensified over time.
• Real estate sales: Declined following the reform, consistent with reduced mortgage availability: first 2 years −0.111 (ns), years 3–4 −0.225***, years 5–6 −0.175***, years 7–8 −0.233***.
• Interest rates: Significant declines attributable to a competition effect for lower-risk borrowers, beyond general Euribor trends (accounted for by time effects). Estimated effects (percentage points): first 2 years −0.312***, years 3–4 −0.757***, years 5–6 −1.033***, years 7–8 −1.303***. Persistence evidenced by positive lag coefficient (≈0.56***).
• Borrower burden (affordability): The average monthly payment-to-wage cost ratio fell after the reform: first 2 years −1.071 (ns), years 3–4 −3.434***, years 5–6 −4.304***, years 7–8 −4.586***, indicating progressive exclusion of higher-burden (lower-income) borrowers.
• Loan size and monthly payment: No consistent significant effects on average loan amount or average monthly payment (most dummies insignificant; some late-period effects warrant caution).
• Controls and dynamics: Unemployment generally negative and significant for lending and sales; inflation negative and house prices positive for several loan term outcomes. Lagged dependent variables are positive and significant across models, supporting dynamic specifications.

The findings support the hypothesis that the 2012 Code of Good Practice altered banks’ lending behavior. Despite widespread bank adherence, institutions appear to have mitigated potential Code-related costs by tightening credit to riskier borrowers most likely to qualify for relief, thereby reducing the number of new mortgages and real estate transactions. Concurrently, increased competition for low-risk borrowers lowered average interest rates, benefitting mainly middle- and higher-income applicants. The sustained decline in the payment-to-wage cost ratio indicates a shift in borrower composition rather than across-the-board easing of payment terms. Time-fixed effects and region-specific trends help net out macro factors such as the Great Recession, Euribor declines, and Basel III rollout, suggesting an additional reform-specific effect captured by the post-reform dummies. While causality cannot be asserted definitively, the convergent evidence indicates the reform contributed to lasting changes in credit allocation and pricing.

The paper shows that Spain’s 2012 debtor-protection reform was associated with three main outcomes: (1) a significant, persistent contraction in new mortgage lending (absolute and per capita), with spillovers to reduced real estate sales; (2) sharper declines in the average monthly payment-to-wage cost ratio, consistent with the exclusion of higher-burden, lower-income borrowers targeted by the reform; and (3) a marked reduction in average mortgage interest rates due to competition for lower-risk borrowers. These results underscore a trade-off: while the Code effectively shields qualifying debtors from foreclosure, it also appears to restrict credit access for low-income households over time. The paper raises policy questions about whether the Code, as designed, is the optimal instrument amid changing conditions (e.g., rising interest rates) and suggests the need to reassess protective mechanisms to avoid unintended exclusion. Future research could exploit microdata on borrower incomes and bank-level heterogeneity, identify quasi-experimental variation, and examine interactions with subsequent legal and regulatory changes.

• Identification: No untreated control group (national reform); reliance on fixed effects and region-specific trends means results are not strictly causal.
• Data aggregation: Regional-level aggregates may mask borrower-level heterogeneity; no disaggregated data by financial entity limits analysis of bank-level responses.
• Variable coverage: Loans data available only from 2007; the affordability proxy (monthly payment-to-wage cost) differs from the Code’s net household income criterion, likely yielding conservative estimates of exclusion.
• Concurrent shocks/policies: Other legal changes (e.g., eviction moratoria, floor-clause rulings), regulatory implementation (Basel III/CRD IV/CRR), and macro-financial factors may contribute despite controls.
• Late-period dummies: Potential influence of additional factors further from the reform date complicates interpretation of later dynamic effects.
