The study concerns judgments from the period 2019–2021 concerning the issue of foreign-currency-denominated loan agreements issued after the Court of Justice of the European Union pronounced its judgment in the Dziubak case, C-260/18. This review aims non only to cite the case law of the Polish Supreme Court, but also to state the author’s doubts relating to the arguments used by the Supreme Court. In particular, the author questions the solution consisting in retaining the agreement as a Polish currency loan agreement, with the interest rate based on LIBOR, and the identical treatment of loans indexed to and denominated in a foreign currency.
