ECB 2026: new rules for accessing Eurosystem funds for banks

Key data

Banks operating with the European Central Bank have new rules in place since 22 January 2026. Guideline ECB/2026/1 amends Guideline ECB/2014/60, the technical framework governing how credit institutions access Eurosystem liquidity: financing auctions, standing facilities and collateral management.

The change is not cosmetic. It affects the operational procedures that banks use on a daily basis to manage their treasury and collateral assets vis-à-vis the ECB. Any adjustment to eligible collateral requirements or applied haircuts has direct consequences on how much liquidity a bank can obtain and at what cost.

What does this regulation establish?

Guideline ECB/2026/1 introduces technical amendments to Guideline (EU) 2015/510 (ECB/2014/60), which is the base regulation of the Eurosystem monetary policy framework. This base regulation defines the rules for banks to access ECB financing.

The specific areas that may be affected by this update are:

• Financing auctions: procedures and conditions for credit institutions to participate in ECB open market operations.
• Standing facilities: conditions for accessing the marginal lending facility and the Eurosystem deposit facility.
• Eligible collateral: possible adjustments to which assets banks may submit as collateral to obtain ECB financing.
• Haircuts: possible changes to the discounts the ECB applies to the value of collateral assets provided by banks.
• Operational procedures: technical criteria that banks must follow in the internal management of their collateral assets and treasury operations.

Economic and operational impact

For banks, the impact is direct and operational. Any modification to eligible collateral criteria or haircuts affects the actual capacity to obtain liquidity from the ECB. If an asset ceases to be eligible or is subject to a higher haircut, the bank obtains less financing for the same asset, which may force it to seek more expensive alternatives or reduce its lending capacity.

Treasury and asset management departments of Spanish banks must review their internal procedures to ensure compliance with the new technical criteria established by the ECB.

For non-financial companies, the impact is indirect but real:

• If banks face greater restrictions or costs in accessing ECB liquidity, they may pass those costs on to the financing conditions they offer their clients.
• The availability of bank credit may be conditioned by banks' ability to access cheap Eurosystem financing.
• Companies with revolving credit lines or short-term financing are most exposed to changes in bank liquidity conditions.

Who is affected?

• Spanish credit institutions participating in ECB financing operations (auctions, standing facilities).
• Treasury and ALM departments (Asset and Liability Management) of banks managing collateral vis-à-vis the Eurosystem.
• Compliance officers at financial institutions who must adapt internal procedures.
• CFOs and financial directors of non-financial companies with significant dependence on short- and medium-term bank credit.
• Financial advisors and consultants working with credit institutions or with companies managing their banking relationships.

Practical example

A mid-sized Spanish bank that regularly uses sovereign bonds and covered bonds as collateral to access ECB financing auctions must review whether those assets remain fully eligible under the new technical criteria of Guideline ECB/2026/1.

If the update introduces an additional haircut on any of those assets, the bank will obtain less liquidity for the same volume of collateral provided. To maintain the same level of financing, it will need to provide more collateral or seek alternative eligible assets. This has a direct operational cost for the treasury department and may affect the profitability of wholesale financing operations.

From the perspective of a corporate client of that bank, if the institution reduces its capacity for cheap ECB financing, it may revise upward the interest rates on its credit lines or tighten renewal conditions.

What should companies do now?

1. Banks and credit institutions: review internal treasury and collateral asset management procedures to identify what operational changes Guideline ECB/2026/1 requires compared to the previous framework (ECB/2014/60).
2. ALM and treasury departments: audit the current collateral inventory and verify whether all assets remain eligible under the new ECB technical criteria.
3. Compliance officers: document the procedural changes adopted and ensure that operational teams are aware of the new technical requirements as of 22 January 2026.
4. CFOs of non-financial companies: engage in proactive conversations with their banks to understand whether changes in ECB liquidity access may affect the conditions of their credit lines or short-term financing.
5. All affected parties: consult the full text of Guideline (EU) 2026/689 published in the Official Journal of the EU to identify the specific technical changes relative to Guideline (EU) 2015/510.
