The table below shows the actual 
interest rates for the current month's Singapore Savings Bonds (SSB), 
which are computed as the average of the previous month's yields of the 
Singapore Government Securities (SGS). The SGS yields can be found at 
https://secure.sgs.gov.sg/fdanet/SgsBenchmarkIssuePrices.aspx.
The
 table also shows the average current month's yields of the 1-year, 
2-year, 5-year and 10-year SGS to-date, which would translate to be the 
interest rates (roughly) for the next month's SSB if SGS yields do not 
change significantly for the rest of the month. The shortcoming of this 
estimate is that it does not take into account the SGS yields for the 
rest of the month. Hence, the second estimate assumes that the average 
SGS yields for the remaining working days of the month is the same as 
that for the latest available date. In the case below, the SGS yields 
for 23 Sep is assumed to apply for the remaining working days of the 
month to compute the average yields for Sep.
 
 
  | 
 | 1-Year | 2-Year | 5-Year | 10-Year | 
  | SSB Rates for Sep | 0.96% | 1.02% | 2.01% | 2.63% | 
  | Avg SGS Yield for Aug | 0.96% | 1.03% | 2.03% | 2.63% | 
  | Avg SGS Yield for Sep (Todate) | 1.15% | 1.15% | 2.21% | 2.81% | 
  | Avg SGS Yield for Sep (Estimated) | 1.18% | 1.17% | 2.20% | 2.78% | 
  | Difference (Todate) | 0.19% | 0.12% | 0.18% | 0.18% | 
  | Difference (Estimated) | 0.21% | 0.15% | 0.17% | 0.16% |
