Generally speaking, no interest is charged for margin trading and securities lending on the same day of borrowing and repayment, but normal transaction commissions are charged. Because margin trading and securities lending are calculated based on the number of days, if you repay on the same day, generally no interest will be charged.

The specific situation is as follows:

Generally speaking, the interest on margin financing and securities lending is the interest from the time you start doing margin trading and securities lending to the completion of the transaction, and is accrued on a daily basis. Deducted on a monthly basis.

1. First of all, if you want to do margin financing and securities lending, you must understand the financing interest rate and the securities lending interest rate. The financing interest rate is equal to the one-year bank loan interest rate, and the securities lending interest rate is added to this basis by an annualized rate of 2%. This interest is variable and not a fixed value. It is basically the one-year loan interest rate plus two or three points. For details, you can ask the brokerage company where you opened the account.

2. Interest is calculated on a daily basis (about 2.53% per day), which is more flexible than bank loans. The most common standards are: the annual interest rate for financing is 8.10%, and the annual interest rate for securities lending is 10.10%. For example, if you finance 1 million yuan, the annual interest rate is 81,000 yuan. And it only took you 30 days to pay back the money. Then the interest you pay is: 8.1*30/365=0.66 million yuan.

3. The current interest rate for financing is 2.458 yuan/10,000 yuan/day, and the interest rate for securities lending is 3.013 yuan/10,000 yuan/day. This interest rate is relatively low compared to other financing channels. You can operate T+0 on the same day of selling securities. As long as you buy it back at the end of the day and pay back the securities, no interest will be charged if you don't stay overnight.

4. If you repay the 100,000 yuan coupon after one day, the interest will be 10*3.013=30.13 yuan. The interest on margin financing and securities lending is calculated on a daily basis. If the annual interest rate is 8.6%, the interest per day for 10,000 yuan in margin financing or securities lending is more than two yuan. If you do not repay the money after financing, the interest will be repaid once a month. If a financing transaction is completed in the middle, it will be calculated at the end.

5. By multiplying the amount by the annual interest and dividing it by 365 days, you can simply calculate the daily interest charged for ten thousand yuan. Calculated at 8.6%, the interest per day per RMB 100,000 is 23.5 yuan. The current interest rate for financing is 9.1%/year, and the interest rate for securities lending is 11.1%/year. The interest rates for margin financing and securities lending are uniform among all securities companies. The interest is calculated on a daily basis. The interest will be charged for as many days as the loan is borrowed.
