Legal analysis: The judicial interpretation of the Supreme People’s Court has made it clear that the upper limit of the court’s discretion when credit card interest and liquidated damages are too high does not refer to private lending interest rates.

Legal basis: "Regulations of the Supreme People's Court on Several Issues Concerning the Trial of Bank Card Civil Disputes" Article 2 When entering into a bank card contract with the cardholder, the card issuing bank shall charge interest, compound interest, fees, If the standard clauses such as liquidated damages fail to fulfill the obligation to present or explain, resulting in the cardholder not paying attention to or understanding the clause, and the cardholder claims that the clause does not become the content of the contract and is not binding on him, the People's Court shall support it. The card issuer requires the cardholder to pay overdraft interest, compound interest, liquidated damages, etc., or to pay installment fees, interest, liquidated damages, etc. in accordance with the credit card contract. The cardholder requests appropriate payment on the grounds that the total amount claimed by the card issuer is too high. If the amount is reduced, the people's court shall comprehensively consider the relevant national financial regulatory regulations, the amount and period of outstanding repayment, the degree of fault of the parties, the actual losses of the card issuer and other factors, weigh it in accordance with the principles of fairness and good faith, and make a ruling.
