Banking Law and Liquidity Risk Management Standards in Spain

Jurisdiction: Spain and the European Union

Liquidity risk is the risk that a bank cannot pay depositors and other creditors when payments fall due without selling assets at heavy losses or obtaining unusually expensive funding. In Spain, the main binding standards come from EU banking law. Spanish law and Banco de España rules supplement that framework, while the European Central Bank (ECB) directly supervises significant Spanish banks.

1. The principal liquidity standards

Liquidity Coverage Ratio (LCR). A bank must hold enough qualifying high-quality liquid assets to cover its net cash outflows over a 30-day stress period. The usual minimum is 100%. The calculation applies prescribed assumptions to matters such as deposit withdrawals, wholesale funding and expected inflows. The buffer is available for use during stress; a fall below the requirement calls for prompt supervisory attention and restoration measures. The detailed calculation is governed principally by Regulation (EU) 2015/61, made under the Capital Requirements Regulation (CRR).

Net Stable Funding Ratio (NSFR). This longer-term measure requires a bank’s available stable funding to be at least equal to its required stable funding: an NSFR of at least 100%. Its purpose is to reduce excessive reliance on short-term borrowing to support assets that remain on the balance sheet for much longer. The requirement forms part of the CRR framework, as amended by Regulation (EU) 2019/876.

Internal liquidity adequacy assessment process (ILAAP). Meeting the two ratios alone does not establish that a bank manages liquidity safely. Its governing body must understand the bank’s funding risks, set a risk appetite, oversee credible stress tests and maintain a workable contingency funding plan. The ECB’s ILAAP guide explains its supervisory expectations; the guide is supervisory guidance, rather than a separate statute replacing binding EU requirements.

In practice, a Spanish bank should also measure cash flows across several time horizons; test deposit runs, market closures and collateral calls; monitor funding concentration and assets pledged as security; and identify where cash may be trapped in a subsidiary or another currency. Supervisors examine these arrangements through the Supervisory Review and Evaluation Process (SREP) and may require improvements where the bank’s particular risks warrant them. Banco de España Circular 2/2016 forms part of Spain’s supplementary supervision and solvency framework.

2. Why liquidity management matters in Spain

A bank can have valuable assets yet lack enough immediately available cash to meet withdrawals. Banco Popular Español illustrates the speed of that problem: its stressed liquidity position led the ECB to determine in June 2017 that it was failing or likely to fail, followed by resolution under the EU Single Resolution Mechanism. Resolution is an emergency response to bank failure, not a substitute for complying with ordinary LCR, NSFR and governance standards.

3. Six relevant judgments

The reported cases below concern Banco Popular’s liquidity crisis and its resolution. They help explain the consequences of severe liquidity failure and the legal scrutiny of supervisory and resolution decisions. They do not each interpret the day-to-day LCR or NSFR calculation rules, and several arise from the same resolution decision.

Legal takeaway: Spanish banks must maintain the prescribed short-term liquidity buffer and stable funding, but they must also be able to manage an actual funding shock. The Banco Popular judgments demonstrate how serious a liquidity failure can become and how courts review the resulting resolution. They should not be described as six separate rulings establishing six liquidity-management standards.
