The main function of the Debt Service Fund is to strengthen debt management, increase financial performance, and reduce the debt pressure. Debt refinancing smoothes the annual debt service and improves the debt structure. In 2020, the Fund refinanced NT$556.3 billion of debt, and together with the NT$85 billion mandatory principal payments credited to the total budget, a total of NT$641.3 billion outstanding debts were repaid. A total of NT$67 million in debt interest was saved by early repayment of outstanding debts due within 2020.
