A fixed deposit, a high-yield savings account and a money market fund can all hold cash you do not need today, but only two of them are deposits. Fixed deposits and savings accounts are bank deposits, insured up to S$100,000 per bank. A money market fund is an investment fund: it is not guaranteed and not covered by deposit insurance.
That difference matters more than a few tenths of a percent in yield. Here is how the three compare, using rates published at the time of writing (November 2026).
Fixed Deposit vs Money Market Fund vs Savings Account at a Glance
| Fixed deposit | High-yield savings account | Money market fund | |
|---|---|---|---|
| What it is | Bank deposit for a fixed term | Bank deposit, withdraw any time | Investment fund; you own units |
| Return | Fixed for the term | Variable; often depends on conditions | Not guaranteed; varies with what the fund holds, less fees |
| Deposit insurance | Yes, SGD up to $100,000 per bank | Yes, SGD up to $100,000 per bank | No |
| Getting money out | At maturity; early withdrawal may lose interest | Usually immediate | On the fund’s dealing days, by its rules |
| Can you get back less than you put in? | Possible if an early withdrawal fee applies | Only through account fees | Yes |
| Example rate, November 2026 | 2.20% for 6 months (CIMB online promotion) | “Up to” advertised rates with conditions | Check the fund’s factsheet |
Sources: MoneySense on deposit insurance and unit trusts, and the providers’ own pages.
The short version: Fixed deposits and savings accounts are insured deposits; a money market fund is an investment that can fall in value. Choose by how soon you need the money and whether you can accept any loss, then compare returns.
Fixed Deposits: Certain Rate, Locked Term
You know the return in advance. At the time of writing (November 2026), promotions for new money paid up to 2.20% a year for six months and 2.30% for 12 months; board rates were far lower, such as DBS’s 0.05% for a total balance of S$20,000 or more. See this month’s FD rates.
The cost is access. MoneySense warns that breaking a deposit early can mean losing some or all of the interest, and possibly a fee. Our guide to fixed deposit early withdrawal compares banks.
High-Yield Savings Accounts: Access, With Conditions
Savings accounts let you withdraw any time. Their headline rates are usually “up to” figures that need conditions such as salary credit, card spend or a minimum balance, and often apply only to part of your balance.
Two examples from providers’ homepages at the time of writing (November 2026):
- Trust Bank advertised “up to 2.4% p.a.” on the first S$1.2 million, across three plans.
- MariBank advertised “up to 3.08% p.a.”, subject to its bonus interest promotion terms.
Read the conditions before comparing with a fixed deposit: the rate you actually earn may be much lower. Our guides to high interest savings accounts and how bonus interest works work through real examples.
Money Market Funds: Not a Deposit
A money market fund pools investors’ money and invests it in short-term instruments. Some platforms offer them as “cash management” accounts. Key points from MoneySense:
- Not guaranteed. “Funds are not principal or capital-guaranteed”, and you may lose money invested.
- Not insured. Deposit insurance does not cover investment products such as unit trusts.
- Fees. The manager is paid a management fee from the fund, usually whether the fund does well or not.
- Access. Unlisted funds can only be redeemed on the fund’s dealing days.
Returns tend to move with short-term interest rates, so they can fall as well as rise. Before using one, read the prospectus and factsheet for what it holds, its fees and its redemption terms, and check the manager in the MAS Financial Institutions Directory.
Worked Example: S$30,000 for Six Months
Illustration only, not a forecast. Simple interest, before fees; the savings and fund rates are hypothetical.
| Option | Rate used | About what it earns in six months | Insured? |
|---|---|---|---|
| CIMB online 6-month promotion | 2.20% | $330 | Yes |
| 6-month T-bill, 4 November 2026 cut-off | 1.86% | $279 | Government-backed |
| Savings account, base rate only | Hypothetical 0.05% | $7.50 | Yes |
| Savings account, bonus conditions met | Hypothetical 2.00% | $300 | Yes |
| Money market fund | Hypothetical 2.00% after fees | About $300, could be more or less | No |
On these figures the gap between the options is small, except where a savings account earns only its base rate. The bigger differences are in risk and access, not return.
Who Each Option Does Not Suit
- Fixed deposit: money you might need before maturity, such as an emergency fund.
- High-yield savings account: people who cannot meet the bonus conditions every month, or balances well above the bonus cap.
- Money market fund: anyone who cannot accept any fall in value, or who wants deposit insurance.
What To Do Next
- Set aside an emergency fund in a savings account first; our emergency fund calculator helps size it.
- For money you can lock away, compare this month’s fixed deposits with T-bills and Savings Bonds in our alternatives to savings accounts guide.
- If you consider a money market fund, do your own due diligence: read its prospectus and factsheet, check its fees and dealing days, and look up the manager in the MAS Financial Institutions Directory.
