Legal analysis: If the annual interest rate exceeds 24%, it is usury, and anything exceeding it is not protected by the law.

Legal basis: "Regulations of the Supreme People's Court on Several Issues Concerning the Application of Law in the Trial of Private Lending Cases" Article 26 If the interest rate agreed upon by both parties does not exceed the annual interest rate of 24%, the lender requests the borrower to comply with the agreement If interest is paid at an interest rate, the people's court shall support it. If the interest rate agreed between the borrower and the lender exceeds the annual interest rate by 36%, the excess interest agreement is invalid.
