According to Xicai.com's inquiry, it is not cost-effective to do reverse repurchase every day. The reverse repurchase of national debt is positioned as a short-term financial management tool, and the interest rate is usually not high, which is generally similar to that of national debt, at around 3%. If you do reverse repurchase every day, you may miss other investment opportunities. The reverse repurchase of government bonds will only soar at the end of the month and at the end of the year when the demand for funds is large.
