Short answer: An eligible Singapore-dollar fixed deposit at a Deposit Insurance Scheme (DI Scheme) member’s Singapore branch can be covered by Singapore Deposit Insurance Corporation (SDIC) insurance, subject to a S$100,000 aggregate limit per depositor per Scheme member. Singapore Treasury bills (T-bills) and Singapore Savings Bonds (SSBs) are government securities, not deposits, so SDIC deposit insurance does not apply to them. Their separate backing is the Singapore Government.
Coverage at a glance
| Holding | SDIC deposit insurance? | What supports the holding | Key access or term features |
|---|---|---|---|
| Singapore-dollar fixed deposit at an eligible member’s Singapore branch | Potentially yes | SDIC coverage for qualifying deposits, capped at S$100,000 in aggregate per depositor per Scheme member | Fixed term set by the account; early withdrawal conditions depend on the institution |
| Singapore Treasury bill (T-bill) | No | Fully backed by the Singapore Government, according to the Monetary Authority of Singapore (MAS) | Six-month or one-year tenor; issued at a discount and paid at face value at maturity; transferable |
| Singapore Savings Bond (SSB) | No | Fully backed by the Singapore Government, according to MAS | Term of up to 10 years; step-up interest; monthly redemption without penalty; generally not transferable |
“Government-backed” and “deposit-insured” describe different legal arrangements. SDIC insurance applies to qualifying deposits held with participating banks and finance companies. T-bills and SSBs are securities issued by the Singapore Government, so their protection does not come from the Deposit Insurance Scheme.

What Singapore’s Deposit Insurance Scheme covers
SDIC states that it insures Singapore-dollar-denominated deposits placed with a DI Scheme member in any of that member’s branches in Singapore. The listed deposit categories include savings accounts, current accounts and fixed-deposit accounts, provided the product and placement meet the scheme’s requirements.
The word deposit matters. A product offered through a bank is not automatically an insured deposit. Securities, unit trusts and other investment products are outside SDIC deposit-insurance coverage. Foreign-currency deposits are also excluded from the ordinary Singapore-dollar coverage described by SDIC.

Check the institution, not just the brand name
Full banks and finance companies operating in Singapore are DI Scheme members unless the Monetary Authority of Singapore has exempted them. SDIC maintains a current member list. A named fixed-deposit product should also appear in the institution’s register of insured deposits. Account documents and marketing material for insured products carry a DI Scheme disclosure statement, which provides another practical check.
The S$100,000 limit is aggregated
SDIC’s current FAQ states a maximum of S$100,000 in aggregate per depositor per Scheme member for ordinary covered deposit categories. The page does not state a publication year; the figure is attributed to SDIC’s current guidance, accessed in 2026.
Accounts at the same member are combined before the limit is applied. A depositor with S$60,000 in a savings account and S$60,000 in an eligible fixed deposit at that member has S$120,000 of ordinary covered deposits. Up to S$100,000 falls within the stated SDIC maximum, while S$20,000 is above the insured limit. This example illustrates the aggregation rule; it is not a bank offer or interest-rate quotation.

Deposits held with different DI Scheme members have separate per-member limits. Splitting money between members therefore changes how the per-member cap is applied, but each account must still independently qualify as an insured deposit.
Special account categories need separate treatment
SDIC describes distinct rules for some arrangements, including trust and client accounts, CPF Investment Scheme (CPFIS) and CPF Retirement Sum Scheme (CPFRS) balances, and joint accounts. These categories may be aggregated or handled differently from an individual’s ordinary savings and fixed-deposit accounts. Do not assume that a CPF-related balance or a trust account simply adds another ordinary S$100,000 allowance. Confirm the applicable category with SDIC and the institution.
Why T-bills are not deposit-insured
A Singapore T-bill is a short-term Singapore Government Security, not a bank deposit. MAS describes T-bills as being issued at a discount: you pay less than the bill’s face value and receive the face value at maturity. Standard tenors are six months and one year. T-bills are transferable, subject to the relevant market and account arrangements.
Because a T-bill is a security, it falls under SDIC’s exclusion of securities and other investment products. Buying a T-bill through a bank or brokerage account does not turn it into a deposit. Cash that remains as a qualifying deposit may be assessed under SDIC rules, but the T-bill itself is not deposit-insured.

That is the source of support cited for the security; it is not an SDIC insurance promise. The return you receive also depends on the bill’s purchase price, maturity and any transaction costs or market conditions if you sell before maturity.
Why Singapore Savings Bonds are not deposit-insured
SSBs are a special type of Singapore Government Security. MAS says they are fully backed by the Singapore Government, but they are not deposits and therefore are not covered by SDIC deposit insurance.
Rank #4
Features that distinguish SSBs from fixed deposits
- Longer possible term: an SSB can run for up to 10 years.
- Step-up interest: the interest rate increases over the bond’s schedule, subject to the issue’s terms.
- Monthly exit: investors may redeem in any month without an early-redemption penalty; MAS says redemption returns principal plus accrued interest.
- Minimum investment: MAS lists S$500 as the minimum investment for SSBs.
- Transferability: SSBs are not transferable in ordinary circumstances.
These characteristics explain why savers sometimes compare SSBs with fixed deposits, but they do not alter the product classification. The bond remains a government security rather than an insured bank deposit.
Deposit insurance versus government backing
The two forms of protection should be kept separate when assessing risk:
Recommended Free Tools
| Question | Eligible fixed deposit | T-bill or SSB |
|---|---|---|
| What is the legal product type? | Bank or finance-company deposit | Singapore Government Security |
| Does SDIC insure it? | Potentially, if the SGD, member and Singapore-branch conditions are met, and only within applicable limits | No; securities are outside SDIC deposit-insurance coverage |
| What backing is identified by MAS? | Not the basis of SDIC coverage | Fully backed by the Singapore Government |
| How is access determined? | By the fixed-deposit contract and the institution’s early-withdrawal rules | T-bills mature on their six-month or one-year schedule; SSBs offer monthly redemption under their terms |
| Can the holding be transferred? | It is an account contract; transfer rules depend on the institution | T-bills are transferable; SSBs generally are not transferable |
Neither category should be labelled universally “safer” without defining the question. Deposit insurance addresses the failure of a participating deposit-taking institution and only to the extent of the scheme’s rules. Government backing describes the issuer of T-bills and SSBs. Liquidity, maturity, price and account conditions are separate decisions.

How to verify whether your fixed deposit qualifies
- Identify the legal institution. Look up the bank or finance company on SDIC’s current DI Scheme member list. Do not rely only on a trading name or a comparison-site label.
- Confirm the currency. The ordinary coverage described by SDIC is for Singapore-dollar deposits. A foreign-currency fixed deposit does not qualify under that category.
- Confirm the booking location. The deposit must be placed with the member in one of its branches in Singapore. An overseas branch is not the same placement.
- Check the exact product. Read the institution’s register of insured deposits and the account’s terms. Look for the DI Scheme disclosure statement in the account documents or marketing material.
- Add your balances at that member. Combine ordinary savings, current and eligible fixed-deposit balances held by the same depositor before comparing the total with S$100,000.
- Classify special accounts correctly. If the money is in a joint, trust, client, CPFIS or CPFRS arrangement, apply the specific SDIC treatment for that category rather than the ordinary individual-account example.
- Separate cash from investments. Cash held in a qualifying deposit account may be assessed under SDIC rules; a T-bill, SSB or another security bought through that account is not converted into an insured deposit.
How to choose between the three holdings
If deposit-insurance eligibility is your priority
Start with an SGD fixed deposit that satisfies the member, Singapore-branch and product conditions. Keep the aggregate balance at each member within the applicable limit if you want the full amount to fall within the ordinary S$100,000 maximum. Verify the account rather than assuming every fixed deposit is covered.
If you want a short, defined government-security maturity
A T-bill provides a six-month or one-year maturity structure and is issued below face value. It is not a deposit-insured product, but MAS identifies it as fully backed by the Singapore Government. Selling before maturity introduces market and transaction considerations that do not arise in the same way when simply holding to maturity.
If you want flexible monthly redemption over a longer horizon
An SSB can have a term of up to 10 years, pays step-up interest and may be redeemed in any month without penalty under MAS’s description. It is not deposit-insured, and ordinary transfer is generally unavailable. The S$500 minimum makes it accessible for smaller allocations, but the bond’s terms and redemption processing still apply.

Common mistakes to avoid
- Counting each account as a separate S$100,000 allowance: ordinary accounts at one member are aggregated.
- Treating a bank’s sales channel as proof of insurance: a security purchased through a bank remains a security.
- Calling government backing “deposit insurance”: MAS’s statement about backing and SDIC’s insurance coverage are different claims.
- Assuming every currency qualifies: the ordinary SDIC category is Singapore-dollar deposits.
- Ignoring the branch condition: the listed coverage requires placement with the member in a Singapore branch.
- Applying ordinary-account rules to CPF, trust or joint arrangements: these have separate treatment that can affect aggregation.
- Using an old product description: member status, registers, statutory limits and issue terms can change, so check the current SDIC and MAS information before placing money.
Bottom line
An eligible Singapore-dollar fixed deposit at a DI Scheme member’s Singapore branch can receive SDIC deposit insurance, generally up to S$100,000 in aggregate per depositor per member. T-bills and Singapore Savings Bonds are not covered by that insurance because they are government securities. MAS states that both are fully backed by the Singapore Government, which is a different form of support. Confirm the institution, account type, currency, branch and aggregate balances before treating any holding as insured.
