Attempts to undermine WIBOR-based agreements – what the banks might expect in 2025

20 January 2025 | Knowledge, News, The Right Focus

An increasing number of borrowers are choosing to challenge their WIBOR-based variable interest rate mortgage loan agreements in court. They accuse banks of violating a number of legal acts, ranging from the Polish Civil Code or the Mortgage Act to the MIFID I, MIFID II EU directives and the Benchmark Regulation.

The most far-reaching demand is to invalidate the credit facility agreements, which, if upheld by the courts (although such a scenario is highly unlikely), would be a huge challenge for the entire banking sector.

Are the borrowers’ claims legitimate?

What is the WIBOR benchmark and why is it being challenged?

Pursuant to Article 3(1)(22) of the Benchmark Regulation, ‘interest rate benchmark’ means a benchmark which (…) is determined on the basis of the rate at which banks may lend to, or borrow from, other banks, or agents other than banks, in the money market.

The WSE Benchmark indicates that “WIBOR® is an interest rate benchmark reflecting the level of interest rate at which banks could place cash (deposits) with other banks for a specified term.”

WIBOR is used to determine the interest rate in mortgage agreements. Typically, the interest rate is set as the aggregate of WIBOR and the bank’s fixed margin.

Borrowers’ claims against the legality of WIBOR revolve around the lack of transparency of the contractual provisions introducing interest rates based on WIBOR, as well as the shifting of the risk associated with the application of variable interest rates solely to the borrowers.

The banks’ customers argue that the details of the variable interest rate clause based on the 3M/6M WIBOR interest rate benchmark, including the impact of this clause on the borrower’s financial obligations, were not explained to them, either at the pre-contractual stage or at the conclusion of the mortgage loan agreement.

Furthermore, they consider that the agreements are contrary to good practice and grossly infringe their interests, as the structure of the variable interest rate clause results in an unequal distribution of the risk of interest rate increases between the parties to the loan agreement.

Notwithstanding the above, they also point to the 3M/6M WIBOR interest rate benchmark being inconsistent with the Benchmark Regulation.

According to borrowers, the 3M/6M WIBOR benchmark is not developed on the basis of interbank lending transaction rates but is usually based on hypothetical data – the rate at which banks would “lend” money to each other.

Therefore, in the opinion of borrowers, WIBOR does not meet the overriding objective of the regulation, i.e. it does not reflect economic realities, giving banks room for abuse and additional earnings at the expense of customers.

Challenging WIBOR. What is the feedback of the courts?

To date, there has not been a single final judgment finding WIBOR defective.

The courts do not agree with any of the claimants’ arguments, refuting all the claims raised by the borrowers and their attorneys.

Four questions for a preliminary ruling submitted by the Regional Court in Częstochowa on 31 May 2024 in Case No. I C 1226/23 may serve as a pretext for analysing the case law to date in this respect.

Is WIBOR subject to the Unfair Terms in Consumer Contracts Directive?

In answering the first question, the Court of Justice of the European Union will have to decide whether WIBOR is subject to Council Directive 93/13/EEC of 5 April 1993 on unfair terms in consumer contracts.

Currently, the courts take the position favouring the banks that the rate is not subject to the Directive as it reflects the provisions of the Benchmark Regulation.

This means that such contractual provisions cannot be examined in terms of abusiveness, as the reference to WIBOR used in the contracts follows directly from the EU Regulation.

If the CJEU responds to the first question affirmatively, it will then have to assess whether the provisions define the main subject matter of the contract, or the adequacy of the price and remuneration on the one hand, as against the services or goods supplies in exchange, on the other, and whether they are expressed in plain intelligible language.

The prevailing view is that the provisions define the main subject matter of the contract and therefore they are not to be assessed in terms of the unfair nature of the contractual terms. In addition, the statements of reasons of the judgments provide that they are transparent, i.e. are expressed in plain intelligible language. As regards the transparency requirement, the courts also point out that the banks did not breach the information requirements as they duly and comprehensively informed borrowers about WIBOR.

An example of this is the judgment of the Regional Court in Warsaw of 23 October 2023 in Case No. XXV C 192/23, where in the statement of reasons, we find that “for the consideration to be completed, it should be pointed out (…) that the variable interest rate clause regulated in the disputed agreement should be treated as a clause concerning the main performance, and this clause, being transparent, would not be subject to examination for abusiveness pursuant to the exemption under Article 4(2) of EU Directive 93/13.”

Do agreements between customers and banks contain unfair provisions?

By formulating the third question, the Regional Court wanted to obtain an answer to the question of whether the contractual provisions concerning the variable interest rate based on WIBOR are contrary to the requirement of good faith and cause a significant imbalance in the parties’ rights and obligations arising under the contract, to the detriment of the consumer.

It is currently held that these provisions do not fulfil the conditions of unfairness described in Article 3(1) of the Directive. However, according to the Polish courts, they are not subject to the provisions of the Directive at all.

The judgement of the Regional Court in Legnica of 15 April 2024, issued in Case No. I C 1394/23, is an example of a judgement in favour of the banking sector, where in the statement of reasons we find that “regardless of the argumentation presented above about the lack of grounds for examining the credit interest rate rules on the basis of provisions on prohibited contractual terms, the conditions for unfairness set out in Article 3851 (1) of the Civil Code have not been fulfilled, as the agreement is in no way contrary to good practice, nor does it grossly infringe the interests of the consumer.”

In its response to the last question, the CJEU will have to assess whether a possible breach of the Directive may result in a mortgage loan agreement being continued based only on the bank’s margin, i.e. the transformation of a variable-rate loan agreement  into a fixed-rate loan agreement.

The question seems theoretical since contractual provisions relating to WIBOR are not subject to the Directive at all.

Summary

Currently, the arguments of borrowers challenging the legality of WIBOR are not accepted by the courts.

However, this trend may reverse as more and more claims challenging WIBOR are filed with the courts. If the CJEU responds positively to the first two questions for a preliminary ruling, it is not out of the question that Polish courts will be flooded by claims, and banks will once again face a huge challenge for which they should prepare.

Workplace harassment and discrimination: new regulations for employers

The Sejm has passed an amendment to the Labour Code concerning workplace harassment and discrimination. The changes introduce a broader definition of the concept itself, new forms of harassment, clearer definitions of what constitutes, for example, sexual harassment, and new rules governing the handling of such cases, including the reversal of the burden of proof, higher compensation awards, and the jurisdiction of district courts. The provisions will enter into force on 5 November 2026. We examine what will change and how much time remains to adapt company documents, policies, and the organisation as a whole.

ESG Roadmap. How to identify which regulations apply to your business and build a strategy

As we know, ESG in business is a roadmap made up of numerous obligations arising from different regulatory frameworks. That is why the right question is not “how do I meet all the requirements?” but rather “which of them apply to my business?”. This is a crucial distinction. We explain how to correctly diagnose your regulatory profile and build an effective ESG strategy – one that actually works and gives you a competitive edge.

Announcement of Income Tax Reform

On 19 August, during a press conference, the Prime Minister announced a package of tax changes planned for next year. According to the announcement, the reform is intended, on the one hand, to ease the burden on the middle class and, on the other, to shift a greater fiscal burden onto the wealthiest individuals and the largest companies. We take a look at the proposals included in the announced package and explain what they might mean for taxpayers.

Family foundations and the tax authorities: what draft bill UD447 proposes and why this is not the end of the troubles

Family foundations were intended to provide entrepreneurs with a stable framework for intergenerational wealth management. Yet not even four years have passed since the first such foundations were established, and the rules governing their taxation are set to be changed once again. This is because the scale of interest and the practical problems uncovered have overwhelmed the drafters of the legislation, as best illustrated by the figures – 927 applications for individual tax rulings and 77 opinions issued from the Head of the National Revenue Administration. This does not, however, mean that family foundations are being used on a massive scale for aggressive tax optimisation. A significant proportion of the queries concerned simply how to correctly apply the complex regulations.

NIS2 and the National Cybersecurity System Act in transport: what you need to do before October 2026

The amended Act on the National Cybersecurity System (UKSC) has been in force since 3 April 2026. For transport sector undertakings, this means a specific compliance timeline, including an obligation to register with the National Cybersecurity System (KSC) registry by 3 October 2026. Failure to do so may result in substantial financial penalties, coupled with the risk of personal liability for senior management. Not every undertaking, however, automatically falls within the scope of the new regime. Read on to find out whether your organisation is affected and what you need to do before the deadline for preparation.

Family foundations: the government has done the maths and presented the bill

Three years. That’s how long we’ve been waiting for what the Council of Ministers had seen in the data from the outset – and has now disclosed in its review of the Family Foundation Act. The document not only diagnoses the problems, but also previews substantial changes to rules that founders and their advisers treated as settled and stable. And therein lies a problem that goes far beyond tax matters. If the rules of the game are changed while the game is being played, there can be neither planning stability nor trust in the law. It is no coincidence that one of the greatest concerns among entrepreneurs considering setting up a foundation is not the level of taxation, but the stability of the legal framework – which today is once again being called into question.

Payment Services Regulation (PSR) – between consumer protection and due diligence

The draft Payment Services Regulation (PSR) is one of the most significant elements of the reform of the EU legal framework for payment services. Its principal aim is to enhance the security of cashless transactions and to reduce the scale of financial fraud, in particular that arising from the growth of digital channels. At the same time, the new rules are intended to introduce a liability model that will not result in risk being transferred entirely to financial institutions, whilst retaining an important role for independent due diligence on the part of the user.
