As a form of Internet finance, online lending does not violate relevant legal regulations. However, if someone deliberately attracts others to lend money at high interest rates and uses the funds for arbitrage, or deceives others into lending money by deceptive means, it will constitute a crime and corresponding criminal liability will be pursued. According to Article 26 of the Supreme People's Court's "Regulations on Several Issues Concerning the Application of Law in the Trial of Private Lending Cases", if the agreed interest rate exceeds the annual interest rate of 36, the excess portion is invalid, and the borrower may require the lender to return the amount collected in excess of the annual interest rate of 36 part of the interest. The "Notice of the People's Bank of China on Banning Underground Banks and Combating Usury Activities" stipulates that private personal loan interest rates shall be determined through negotiation between the borrower and the borrower, but the interest rates negotiated by both parties shall not exceed the loan interest rates of financial institutions for the same period and at the same level announced by the People's Bank of China (not applicable). 4 times (including float). Anything exceeding the above standards should be defined as high-interest lending. Secondly, through the "Notice of the People's Bank of China on Banning Underground Banks and Combating Usury Activities", loan sharking is not only not protected by national laws, but also severely cracked down, which shows that it is illegal. Finally, there is no crime of loan sharking in the criminal law. It only stipulates the crime of illegally absorbing public deposits. However, those who violate the criminal law in the process of loan sharking must be held criminally responsible according to law.
