The Tbill cut-off yield in the last auction is 1.44%.
If you select a non-competitive bid, you may be pro-rated the amount you bid and would yield 1.44%. If you would like to ensure you secured all that you bid, it will be better to select a competitive bid, but you need to get your bid right.
Some past non-competitive auctions were pro-rated. Here are some past examples:
In competitive bidding, if your bid is lower than the eventual cut-off yield (in the example below), you will get 100% of what you bid for at the cut-off yield (not the lower yield that you bid for).
Gaining Insights About the Upcoming Singapore T-bill Yield from the Daily Closing Yield of Existing Singapore T-bills.
The table below shows the current interest yield the six-month Singapore T-bills is trading at:
The daily yield at closing gives us a rough indication of how much the 6-month Singapore T-bill will trade at the end of the month. From the daily yield at closing, we should expect the upcoming T-bill yield to trade close to the yield of the last issue.
Currently, the 6-month Singapore T-bills are trading close to a yield of 1.44%, 20 basis points lower than the yield two weeks ago.
Gaining Insights About the Upcoming Singapore T-bill Yield from the Daily Closing Yield of Existing MAS Bills.
Typically, the Monetary Authority of Singapore (MAS) will issue a 4-week and a 12-week MAS Bill to institutional investors.
The credit quality or risk of the MAS Bill should be very similar to that of Singapore T-bills since the Singapore government issues both. The 12-week MAS Bill (3 months) should be the closest term to the six-month Singapore T-bills.
Thus, we can gain insights into the yield of the upcoming T-bill from the daily closing yield of the 12-week MAS Bill.
The cut-off yield for the latest MAS bill auctioned on 2nd Sep (3 days ago) is 1.44%. The MAS bill is 20 basis points lower than the last issue two weeks ago.
Currently, the MAS Bill trades close to 1.45%.
Given that the MAS 12-week yield is at 1.45% and the last traded 6-month T-bill yield is at 1.41%, what will likely be the T-bill yield this time round?
What we are observing is:
- The interest at 3-month is falling at a slower pace than the 6-month.
- The interest at the 6-month is not falling at a greater pace. The more dramatic part is at the 10-year part.
Given where things are I am incline to think that yields will be at slightly lower at 1.40%.

This table is updated as of 17th November 2022.
There are other securities or products that may fail to meet the criteria to give back your principal, high liquidity and good returns. Structured deposits contain derivatives that increase the degree of risk. Many cash management portfolios of Robo-advisers and banks contain short-duration bond funds. Their values may fluctuate in the short term and may not be ideal if you require a 100% return of your principal amount.
The returns provided are not cast in stone and will fluctuate based on the current short-term interest rates. You should adopt more goal-based planning and use the most suitable instruments/securities to help you accumulate or spend down your wealth instead of having all your money in short-term savings & investment options.
