Where to park your cash for higher yield? T-bills vs Fixed Deposit vs SSB (May 2025)

What happened?

It doesn't come as a surprise that interest rates on savings have continued to decline lately. 

The yield on the 6-month Singapore T-bill have dipped to 2.30%, and the yield on the 1-year Singapore T-bill  fell to 2.29%. 

On top of that, interest rates on the UOB One and OCBC 360 savings accounts have also been slashed from 1 May 2025. 

Even the best fixed deposit rates in Singapore have fallen too. 

Naturally, this has sparked fresh conversations in the Beansprout community Many of you have been asking: Where can I still park my cash to earn a decent yield?

In this article, I’ll compare the most popular options, T-bills, fixed deposits, Singapore Savings Bonds (SSBs), and money market funds, to see which ones still hold up.

Here’s what we’ll cover:

• The latest interest rates on fixed deposits, T-bills, SSBs, and money market funds
• Pros and cons of each option
• What I personally look at when deciding where to park my spare cash
• And the strategy I’m using right now to make my money work harder

Latest Singapore Savings Bonds (SSB) offer a 10-year average return of 2.56%

The May issuance of the SSB (SBJUN25 GX25060V) offers a 1-year interest rate of 2.20%, and a 10-year average return of 2.56%. 

This is lower than the 10-year average return of the previous SSB, which was 2.69%. 

I would consider the SSB mainly for the opportunity to lock in the yields for a period of up to 10 years, before interest rates fall further. 

As of 15 May 2025, the 10-year average return of the next SSB is projected to fall to 2.56%.

What are the other options to earn a higher yield? 

Fixed deposits are seen as relatively safe options to park our cash as our savings will be insured to up to S$100,000 under the Singapore Deposit Insurance. 

At the same time T-bills and Singapore Savings Bonds are relatively low risk investment options as they are issued by the Singapore government. 

I have also seen questions in the Beansprout community about some products that are not capital guaranteed. Here, it is important to note that they are not capital guaranteed, even if they were to offer guaranteed rates. 

#1 - Cash Management Accounts that offer more liquidity 

Cash management accounts aim to provide higher potential returns compared to savings accounts, and greater flexibility compared to fixed deposits.

Some examples of cash management accounts include Moomoo Cash Plus, Tiger Vault, Webull Moneybull, Endowus Cash Smart, Mari Invest and Phillip Smart Park 

By putting your money in a cash management account, you will be investing in money market funds or bond funds. 

These professionally managed funds will put your cash in instruments such as bank deposits or short-term debt to earn higher interest rates.

The indicative 7-day annualised yield of the Fullerton SGD Cash Fund was around 2.42% p.a. as of 15 May 2025.

Learn more about the Fullerton SGD Cash Fund here. 

However, it is worth pointing out that these funds are not capital guaranteed, and funds in cash management accounts are not insured under Singapore Deposit Insurance Corporation Limited (SDIC).

#2 – Cash Management Accounts with guaranteed rates

Some robo-advisors have also introduced cash management solutions that offer guaranteed rates. They generate the returns by investing your funds into fixed deposits products provided by banks in Singapore.

For example, Syfe Cash+ Guaranteed is the cash management solution offered by Syfe which offers investors guaranteed rates for their idle cash. 

Syfe Cash+ Guaranteed offers a guaranteed rate of 2.50% per annum for a term of 3 months as of 15 May 2025. 

Learn more about Syfe Cash+ Guaranteed here. 

StashAway Simple Guaranteed offers a 1-month rate of 2.40% p.a. and a 3-month rate of 2.45% p.a. as of 15 May 2025.

 #3 – US dollar denominated options to park your cash 

If you have idle cash denominated in US dollars, you can also consider the following options to earn a higher yield compared to the T-bill.

However, if you are converting from SGD to USD,  you should be aware of the foreign currency exchange risks. This is because the US dollar could weaken against the Singapore dollar. 

USD Fixed Deposits

• The best 3-month US Dollar fixed deposit rate is 4.20% p.a. offered by ICBC.
• The best 6-month US Dollar fixed deposit rate is 4.20% p.a. offered by ICBC.
• The best 12-month US Dollar fixed deposit rate is 4.00% p.a. offered by the Bank of China.

You can check out the best USD fixed deposit interest rates in Singapore here. 

US Treasuries 

US Treasuries are debt securities issued by the US Department of the Treasury, just like the Singapore T-bills are backed by the Singapore government. 

The US 1-year Treasury yield stands at 4.15% as of 15 May 2025, having fallen in recent months due to rising recession concerns.

You can purchase US Treasuries using on either Moomoo Singapore or Tiger Brokers. 

USD Money Market Funds

Some of the cash management accounts also allow us to invest in money market funds denominated in US dollars. 

For example, Moomoo Cash Plus, Tiger Vault, Webull Moneybull allow for investments in USD money market funds.

What to consider when choosing between T-bills vs fixed deposits vs SSB vs money market funds? 

There are 4 questions I would think about when considering these options.

• Am I comfortable with a product that is not be insured by SDIC or backed by the Singapore government?

If I prefer a SDIC insured product, then I would stick to savings accounts and fixed deposits. 

• Will I need the money in short notice? 

If liquidity is of importance as I may need the cash for other uses in short notice, then I may prefer savings accounts where I can have instant withdrawals. 

• Do I want to lock in the yields for a longer time period?

If I am looking to lock in the current high interest rates for a period of up to 10 years and not have to worry about reinvestment risks, then the Singapore Savings Bonds allow me to do so while having the flexibility to redeem anytime.

• Do I have any use for the cash in US dollars?

If I am looking to invest in US stocks or ETFs or have other uses of US dollars, then I may consider the US dollar denominated fixed deposits, money market funds or Treasuries. 

Otherwise, I may face foreign currency risks when converting the money back into Singapore dollar in future. 

What would Beansprout do? 

With the fall in T-bill yield and fixed deposit rates, there are still a few ways to earn an interest rate of above 2.50% p.a.

If I have S$100,000 of cash, I would consider using the UOB Stash Account to earn an interest rate of up to 3.0% per annum in a no-frills way, while tapping on the UOB Cash is King promotion to earn additional cash rewards of up to S$500.

The MariBank Savings Account allows me to earn an interest rate of 2.28% p.a. for up to S$100,000 without having to jump through hoops. 

If I'm looking to lock in guaranteed rates over a 3-month period, I'd consider Syfe Cash+ Guaranteed, which offers 2.5% p.a. and StashAway Simple Guaranteed, which offers 2.45% p.a. 

With falling interest rates, I would also try to lock in interest rates for a longer period of time with the current issuance of the Singapore Savings Bonds (SSB), which offers a 10-year average interest rate of 2.56%, with the flexibility to redeem priority to maturity. 

For more liquidity compared to the T-bill,  I would also consider money market funds to park some of my money. 

If I am willing to take more risks to position my portfolio for falling interest rates, I would look at bond funds which may see potential price appreciation if interest rates come down. 

Whatever option you choose, be sure to understand the product and risks involved before deciding where to park your savings.
