If you borrow 10 thousand yuan, the annual interest rate is above 36% and the annual interest is above 3600 yuan, which is usury.

What is usury is clearly defined in this provision of plain writing with more than 20 words. It tells everyone that the interest rate of private individual loans is determined by both borrowers and borrowers through consultation, but the interest rate determined through consultation between the two parties shall not exceed four times the interest rate of financial institutions at the same level (excluding floating) announced by the People's Bank of China. Those who exceed the above standards should be defined as usury lending.

Extended data:

The big ear hole is to borrow 10 thousand yuan, only to take 9 thousand, but when you pay it back, you have to pay 13 thousand. Moreover, the interest of usury is "nailed" (interest) day by day, calculated by compound interest, which is called "interest overlap". I often borrow hundreds of dollars, and it will take a year and a half to pay it back. With interest, I may have to pay back tens of thousands.

Snowballing usury is mostly carried out between usurers and farmers. The loan term is generally 1 month, and the monthly interest is generally 3-5 cents. If it is not repaid at maturity, the interest will be doubled and included in the principal of next month. By analogy, the principal will increase month by month, and the interest will multiply month by month, just like snowballing.

A lamb's rest is to borrow one and return two. If you borrowed 100 yuan at the beginning of the year, you will return it to 200 yuan at the end of the year.
