With the Spring Festival holiday, A-share markets will be closed, but idle funds can still be put to work. This year's holiday spans 9 days (February 15 to February 23), and since February 14 (Saturday) is also a non-trading day, the total market closure extends to 10 days. This creates a chance to earn interest for an extended period through reverse repurchase agreements.

February 12 (Thursday) is considered the optimal day before the Spring Festival to engage in treasury bond reverse repurchases. By investing in a 1-day reverse repo on this day (GC001, code 204001 for the Shanghai market; R-001, code 131810 for the Shenzhen market), investors can accrue interest over the entire holiday period, totaling 11 days of earnings. The invested funds become available for use the following day (February 13) and can be withdrawn after the holiday on February 24.

To participate, investors need only a stock trading account. During trading hours (until 15:30), they can access the "Treasury Bond Reverse Repo" option in their trading software, select the product, set the interest rate, enter the amount, and place the order. It is important to note that reverse repo rates often drop significantly after 15:00. Investors without plans for stock investments are advised to complete their orders at a satisfactory annualized rate before this time.
