Banco Santander confirms compliance as Bank of Spain updates MREL requirements

The latest update is out from Banco Santander SA ( (SAN) ).

Banco Santander’s resolution group, which encompasses the parent bank and key subsidiaries under its multiple point of entry framework, operates under EU banking regulations that impose minimum requirements for own funds and eligible liabilities. The group’s capital and liability structure is calibrated against risk-weighted assets and leverage exposure to ensure it can absorb losses and be resolved in an orderly manner without destabilizing the wider financial system.

The Bank of Spain has communicated a new binding minimum requirement for own funds and eligible liabilities, both total and subordinated, for Banco Santander’s resolution group, replacing the level set in a 2025 notification. The updated Total MREL and Subordinated MREL, expressed as percentages of risk-weighted assets and leverage exposure, reflect factors including a market confidence charge adjustment, treatment of holdings in Banco Santander México and the sale of 49% of Santander Bank Polska, and current figures show the group already complies with these strengthened loss-absorbing standards.

The revised requirements, when combined with the applicable capital buffers, set a higher overall loss-absorbing capacity threshold that Santander must maintain, reinforcing the resilience of its resolution group. For investors and creditors, the confirmation of full compliance as of year-end 2025 indicates that Santander’s current funding and capital mix is sufficient to meet the new supervisory expectations without immediate additional issuance, supporting confidence in the bank’s regulatory positioning and stability.

The adjustments also underscore the growing importance of subordinated instruments within the bank’s liability structure, as regulators continue to fine-tune MREL frameworks based on evolving group structures and cross-border exposures. By incorporating the impact of recent strategic transactions into the new requirements, authorities signal that balance-sheet optimization moves, such as minority stake sales, have direct consequences for the calibration of loss-absorbing capital in large cross-border banking groups like Santander.

The most recent analyst rating on (SAN) stock is a Hold with a $8.50 price target. To see the full list of analyst forecasts on Banco Santander SA stock, see the SAN Stock Forecast page.
