By Gerald Wong, CFA • 25 Sep 2025
The cut-off yield for the latest 6-month Singapore T-bill on 25 September increased to 1.44% p.a.

What happened?
The results of the the latest 6-month Singapore T-bill auction are out.
The cut off yield for the 6-month Singapore T-bill (BS25119Z) increased to 1.44% in the auction on 25 September from 1.38% in the previous auction.
This slight rebound comes after several months of falling T-bill yields, and represents the first bounce in the T-bill yield since March this year.
For investors still looking at Singapore T-bills as a place to generate passive income. I'll share how it compares to the best fixed deposit rates as a place to park your spare cash.

What we learnt from the latest 6-month Singapore T-bill auction
#1 - Demand for the Singapore T-bill declined
Total applications for the 6-month Singapore T-bill decreased to S$13.5 billion in the latest auction on 25 September from S$15.7 billion on 11 September.
The fall in applications is likely due to the reduced investor demand at the current lower yield levels.
The amount of competitive bids decreased to S$12.6 billion.
If you placed a competitive bid below 1.44%, you would receive 100% of your requested T-bill allocation.
If you bid at exactly 1.44%, the allocation would be around 4%.
The amount of non-competitive bids decreased to S$903.5 million.
Since the amount of non-competitive bids was within the allocation limit, all eligible non-competitive bids received full allocation for the T-bill.
#2 - T-bills issued decreased
The amount of T-bills issued was at $7.7 billion, which was slightly lower than the previous auction on 11 September at $7.8 billion.
With the lower amount of T-bill applications, the ratio of applications to T-bills issued (bid-to-cover ratio) decreased to 1.75x.
#3 - Median yield of bids submitted rose slightly
The median yield of bids submitted rose slightly to 1.33% from 1.31% in the previous auction.
The average yield of bids submitted fell slightly to 1.23% from 1.27% in the previous auction, inline with the fall in bond yields in recent weeks with the US Federal Reserve interest rate cuts.
Given the median yield and the cut-off yield, this suggests that a substantial number of bids were placed in the 1.33% to 1.44% range, on par with the best 6-month fixed deposit rate in Singapore.
What would Beansprout do?
The increase in the T-bill cut-off yield to 1.44% is likely due to lower demand for T-bills, as the average and median yields of vids submitted have remain subdued.
Following the bounce in T-bill cut-off yields, yields are now close to the best 6-month fixed deposit rate in Singapore of 1.40% p.a.
However, they remain below the break-even yield for CPF OA applications, based on calculations using our CPF T-bill calculator.
In light of this, I would consider exploring alternative ways to earn passive income in Singapore.
For example, some savings accounts continue to offer an interest rate of above 1.44% p.a, even though banks have been cutting the interest rates in recent months.
