- The CNMC opened a sanction file against six major Spanish banks over mortgage rate comments.
- Banks argue Spain's mortgage market is highly competitive, with rates below the eurozone average.
- Top executives from Santander, BBVA, CaixaBank, Sabadell, Bankinter, and Unicaja express confidence in their compliance.
- The AEB president highlights that Spanish mortgage rates are one percentage point below the eurozone average.

Spain’s largest financial institutions are defending their mortgage lending practices after the National Commission for Markets and Competition (CNMC) launched an investigation in mid-June. The regulator’s probe targets Santander, BBVA, CaixaBank, Sabadell, Bankinter, and Unicaja, all of which are listed on the stock exchange, over concerns that their executives’ public statements about fixed-rate mortgage pricing may have constituted anti-competitive behavior.
The investigation began on the same day that Cani Fernández stepped down as CNMC president, focusing on comments made by bank leaders regarding interest rates on fixed-rate home loans. According to the regulator, these remarks could have allowed competitors to anticipate future commercial offers, potentially distorting market dynamics. The sector has responded with surprise, emphasizing that the Spanish mortgage market operates with high levels of competition and transparency.
Investigation Background

The six entities under scrutiny are the same ones that regularly hold earnings calls and press conferences with analysts and investors. The CNMC’s case centers on whether their public guidance on mortgage pricing violated competition rules. Financial sources close to the banks argue that the regulator’s arguments, at least those made public, have “very little basis.” They also point out that the CNMC previously dismissed a complaint against Santander, BBVA, CaixaBank, and Sabadell regarding low deposit rates, suggesting a pattern of overreach.
Alejandra Kindelán, president of the Spanish Banking Association (AEB), was quick to defend the sector, stating that Spain’s mortgage market is “the most competitive in Europe.” She noted that among major EU countries, Spain ranks third overall, only behind Malta and Bulgaria, and that the average mortgage rate is a full percentage point below the eurozone average. Kindelán stressed that Spanish banks fully comply with legal requirements, especially in competition matters.
Bank Executives’ Reactions
In recent weeks, the CEOs of the six banks have been cautious when asked about the investigation during public earnings presentations. Héctor Grisi, CEO of Santander, reiterated that Spain has one of the most competitive mortgage markets in Europe and “the world,” adding that mortgage costs are even lower than the country’s sovereign bond yields. This means a private individual can secure financing more cheaply than the state itself.
Onur Genç, CEO of BBVA, avoided direct commentary on the CNMC file but emphasized that the bank is “fully committed” to regulatory compliance and that the Spanish mortgage market is “very competitive,” which explains the interest rates offered. Gonzalo Gortázar, CEO of CaixaBank, expressed respect for the investigation but said the bank is “calm” because it believes its conduct has not breached competition rules. Marc Armengol, CEO of Sabadell, declined to comment further, only noting satisfaction with the bank’s mortgage growth. Gloria Ortiz, CEO of Bankinter, voiced confidence that the case will be resolved favorably, asserting that the bank has acted correctly. Isidro Rubiales, CEO of Unicaja, simply added that mortgages are a key product for the bank.
Industry Defense and Market Position
The industry’s defense rests on the notion that Spain’s mortgage market is exceptionally competitive. Data from the AEB shows that the average mortgage rate in Spain is one percentage point lower than the eurozone average, a gap that has persisted for years. This competitive pricing is attributed to the high number of lenders and the strong presence of both traditional banks and newer digital players. The banks also highlight that they have consistently passed on lower rates to consumers, even as the European Central Bank has adjusted its monetary policy.
Financial analysts note that the CNMC’s investigation could be seen as a response to public statements that might have signaled coordinated pricing behavior. However, the banks argue that their comments were merely factual observations about market conditions, not collusion. The AEB has also pointed out that Spain’s mortgage market is among the most dynamic in Europe, with a wide range of products and competitive terms for consumers.
Despite the regulatory pressure, the Spanish banking sector remains profitable. In the first half of the year, the six listed banks generated a combined net profit of over 20 billion euros, supported by higher interest rates and strong loan demand. This financial strength gives them confidence in navigating the investigation, which they expect to conclude without major penalties.
As the CNMC continues its review, the banks are preparing their formal responses. They maintain that their actions have always been in line with competition laws and that the Spanish mortgage market benefits consumers through low rates and diverse offerings. The outcome of this case will be closely watched by the financial industry, as it could set a precedent for how public statements by bank executives are treated under competition rules.
