Interest rates have been decreasing over the last few months. This can be seen as well by the latest September 2025 issuance of the Singapore Savings Bond, where the average return over 10 years amount to 2.11%. This rate is significantly lower than what was available in the calendar year 2024, where there are months with more than 3.00% average return over 10 years.

The result is that the required yield of assets has decreased as well. This can be seen by the increase in prices of all existing assets, including the Green SGS (Infrastructure) 30-Year Bond. In the latest reopened bid in April 2025, the average yield of 2.50% per annum is the required rate of return by investors, which is representative of the current interest rate environment. With a fixed coupon rate of 3.25% per annum, this translates to a closing price of SGD116.79 per SGD100 of principal amount of the Bonds.
