Here's what to expect for the Singapore T-bill auction on 14 August

#1 – US bond yields remain elevated

The 10-year US government bond yield stood at 4.24% as of 7 August 2025, below levels on 24 July.

While still elevated, the lowered bond yields were driven by softer economic data and renewed tariff concerns. 

According to the CME Fedwatch Tool as of 7 August 2025, there is a 92.1% probability that the US Federal Reserve will cut interest rates by 0.25 basis points in the upcoming meeting.

Likewise, the 1-year US government bond yield stood at 3.91% as of 7 August 2025, dropping sharply below levels on 24 July 2025.

#2 – Singapore bond yields have dipped further

The 10-year Singapore government bond yield stood at 1.96% as of 7 August 2025, down from 2.08% recorded on 24 July.

Yields have retreated once again and now sit near their lowest levels in over a year, underscoring continued investor preference for safer assets amid lingering global uncertainties.

The closing yield on the 6-month T-bill was 1.69% on 7 August 2025,  which is lower than the cut-off yield of 1.77% in the previous T-bill auction on 31 July.

The yield on the 3-month MAS bill can also give an indication of the yields for shorter-maturity Singapore government bonds.

The cut-off yield was at 1.70% in the auction on 5 August 2025, slightly below the yield of 1.73% in the auction on 29 July 2025.

#3 – Issuance size similar to the previous auction

The issuance size of the upcoming 6-month Singapore T-bill is $7.5 billion, slightly lower than the previous auction size of $7.6 billion.

We saw a substantial decrease in the amount of T-bill applications to S$12.9 billion in the auction on 31 July 2025 from S$15.5 billion on 17 July 2025.

If demand continues to decline, the larger amount of T-bill issued may help to provide some support to the cut-off yield in the auction.

What would Beansprout do?

The closing yield on the 6-month Singapore T-bill was at 1.69% on 7 August 2025. It is lower than the cut-off yield in the previous auction.

If you are looking to park an amount below S$20,000, the best 6-month fixed deposit rate of 2.15% is above the closing yield on the 6-month Singapore T-bill yield.  

For an amount of S$20,000 and above, the best 6-month fixed deposit rate of 1.65% p.a. is below the closing yield on the 6-month Singapore T-bill yield.  

One of the ways to secure a potentially higher yield is to consider the Singapore Savings Bonds (SSB), which offers a 1-year return of 1.82% and average annual return of 2.11% over 10 years, while having the flexibility to redeem prior to maturity. 

The closing yield on the 6-month Singapore T-bill would also be below the interest rates currently offered by the best savings accounts in Singapore. 

As such, I may want to consider more concretely where to park my cash for a better yield, and apply for the upcoming auction only if I've already looked at all my other alternatives.
