SRS Interest Rate in Singapore: What Idle SRS Cash Earns and Where It Can Go

Money left uninvested in an SRS account at DBS earns 0.05% interest a year. On a full S$15,300 contribution, that is S$7.65 for a whole year. Over the same period, Singapore's headline consumer prices rose 2.2% year on year in September 2026, so the SRS interest rate on idle cash falls far behind prices.

The SRS interest rate is the deposit rate your operator bank pays on the cash balance inside your Supplementary Retirement Scheme account, before you invest any of it. A lot of money sits at that rate. At the end of 2025, 21% of the SRS investment portfolio across all account holders was still held as cash.

The cash rate only applies until you give an instruction. SRS money can buy shares, unit trusts, bonds, fixed deposits, ETFs and certain life insurance products, and returns earned inside the account are tax-free until you withdraw. Selling an investment sends the proceeds back to SRS cash, so moving between options is not a withdrawal.

The low-risk choices range from bank deposits and Singapore government securities to money market fund portfolios and bond ETFs. Each one quotes its return differently: a deposit rate, an auction yield, a step-up coupon, a projected yield or a market price. Comparing them fairly means looking at what the number measures, how much the price can move, how long the money is tied up and what you pay.

This guide explains what idle SRS cash earns at the bank, what that costs over one year and ten, how each low-risk option defines its return, which platforms offer each one for SRS money, and how to choose between them.

What is the SRS account interest rate in 2026?

Cash in an SRS account is a bank deposit with the operator, so it earns that bank's SRS deposit rate. At DBS/POSB that is 0.05% a year on the SRS balance, the same 0.05% given in POSB's SRS guidance, and POEMS uses that figure too: SRS contributions only earn 0.05% when kept in the bank.

The rate applies only to cash that has not been placed anywhere else. It is a separate number from the interest your CPF accounts earn, which follows CPF's own rules: the Ordinary Account stays at its 2.5% floor rate from 1 October to 31 December 2026. SRS money you have already invested earns whatever the investment returns.

Contribution caps decide how much cash can pile up in a year. For 2026, citizens and PRs can contribute up to S$15,300 and foreigners up to S$35,700, with the relief going to YA 2027. A balance built from several years of contributions can be far larger, and every dollar of it earns the same 0.05% until invested.

How much does idle SRS cash earn?

At 0.05%, a year's interest is small at any balance.

Example only, based on DBS SRS account (as of 3 November 2026). Assumes simple interest, with the balance and the 0.05% rate unchanged for a full year.

The real cost after inflation

Prices rose 2.2% in the year to September 2026. If inflation held at that pace for another year, S$15,300 left as SRS cash would grow to S$15,307.65 but buy only what about S$14,978 buys today. That is a loss of roughly S$322 in purchasing power on one year's contribution.

The tax relief on the contribution is a separate gain. A S$15,300 top-up saves a citizen with S$100,000 of chargeable income S$1,759.50 in tax under the resident rate table, but the money then sits in the account for years, and each year at 0.05% wears down part of what that saving bought.

The gap with low-risk alternatives

The cost of idle cash is easiest to see against the safest alternatives. One year of S$15,300 in SRS cash earns S$7.65. At the 1.95% cut-off yield of the 6-month T-bill auctioned on 22 October 2026, the same amount would earn about S$298 over a year if a second bill cleared at the same yield. At the 1.67% first-year coupon of the November 2026 Singapore Savings Bond, it would earn about S$256.

Example only, based on DBS SRS account, MAS SSB GX26110X issue details and Beansprout T-bill allotment results (as of 3 November 2026). Assumes simple interest, the same 1.95% yield on the second bill, and excludes the S$2 SSB fee.

How each option defines its return

A 1.95% T-bill yield, a 1.67% SSB coupon and a cash portfolio's projected yield look like three versions of the same thing. They measure different things and behave differently after you buy.

Deposit rate. The rate a bank pays on cash or a fixed deposit. On SRS cash it can change at the bank's discretion; on a fixed deposit it is fixed for the tenor you choose.

Auction cut-off yield. The annualised return on a T-bill bought at the auction, earned as the gap between the discounted price you pay and the face value repaid at maturity. It is locked once you are allotted, but the next auction can clear higher or lower.

Step-up coupon. An SSB pays a set coupon that rises each year on a schedule fixed on the day of issue. The November 2026 issue starts at 1.67% and averages 2.45% a year if held for the full 10 years.

Projected or net yield. Money market and cash management portfolios quote a yield calculated from the current yields of the underlying funds, usually after fund fees and sometimes after the platform fee. The figure moves with short-term interest rates and carries no guarantee.

Total return. Bond ETFs and bond funds have no promised rate. Their return is the income they pay plus or minus price changes, and prices fall when interest rates rise.

What each low-risk SRS option's rate measures, and how far the price can move

SRS cash vs fixed deposits vs T-bills vs SSBs vs funds

Each option can be bought with SRS money, but they differ on the five points that matter for idle cash: what the rate means, whether the capital value can fall, how long the money is tied up, what it costs and how you reach it with SRS.

Source: DBS SRS account, DBS T-bill guide, MAS SGS auctions for individuals, MAS SSB GX26110X issue details, MoneySense deposit insurance, POEMS SRS (as of 3 November 2026)

Government securities have the lowest credit risk of the investment options, while deposits are the only ones covered by deposit insurance. Funds and ETFs can return more than both, and their prices can also end the year lower than they started.

Minimums that shape the choice

Small balances limit what you can buy. T-bills have a minimum bid of S$1,000, in multiples of S$1,000. SSBs start at S$500, with a limit of S$200,000 per person across cash and SRS holdings. The flat S$2 SSB fee at DBS takes a much bigger share of the interest on a S$500 application than on S$10,000.

Low-risk SRS options by platform

Your operator bank holds the cash, and other platforms can draw on it for specific purchases. What each platform lets SRS money buy is the main difference between them.

Operator banks: deposits and government securities

DBS/POSB, OCBC and UOB are the only three SRS operators, and between them they offer the widest menus for SRS money. At DBS, SRS funds can go into bonds, SGS and SSBs, SGD and foreign currency fixed deposits, shares, single premium insurance and unit trusts. UOB's SRS range covers unit trusts, insurance, stocks, ETFs, REITs and SSBs. T-bills and SSBs are bought through the operator's internet banking, so this route needs no second platform.

Cash management portfolios

Several digital platforms run money market or short-duration bond portfolios that accept SRS money. They avoid auctions and rollovers, but their yields are projections and the platform fee comes out of the return.

All five accept SRS money. Endowus asks for S$1,000 to start, while Syfe sets no minimum for Cash+ Flexi. The Endowus range also shows how yield and price risk rise together: Secure's largest historical loss was 0.05%, Enhanced's 1.55% and Ultra's 2.88%, in the same order as their net yields.

SGX brokers: bond ETFs and SGX-listed securities

Brokers that accept SRS money settle trades through your operator bank. At POEMS, only SGX-listed securities are eligible for SRS investments, settled in Singapore dollars. POEMS also offers SRS unit trusts from S$1,000. An SGX-listed bond ETF bought this way pays distributions back into SRS cash.

StashAway ETF Explorer: bond ETFs beyond SGX

Of the platforms compared here, StashAway is the only one where SRS money can buy US-listed and UCITS ETFs directly; the brokers stick to SGX-listed securities and Endowus and Syfe reach global markets through unit trusts and index funds. That widens the low-risk shelf to bond ETFs listed in New York and London, alongside SGX-listed ones.

A bond ETF bought in US dollars adds currency risk on top of interest rate risk, since the value is converted back to Singapore dollars when you sell.

Worked example: S$15,300 over 10 years at three rates

The cost of idle cash grows with time. Take one full S$15,300 contribution left in SRS for 10 years with no further top-ups and no withdrawals, compounding once a year at three rates. The 0.05% is the DBS cash rate; 2% and 4% are hypothetical net returns, used only to show the effect of time.

Example only, based on DBS SRS account (as of 3 November 2026). Assumes annual compounding, fees already deducted from the 2% and 4% rates, no further contributions or withdrawals, and no tax until withdrawal.

Ten years of idle cash adds less than S$77. At a 2% net return the same money gains about 44 times as much, and the gap widens every year after that. When the money is eventually withdrawn on or after your prescribed retirement age, 50% of each withdrawal is taxable, so the extra growth is taxed on the same terms as the original contribution.

Is SRS cash covered by deposit insurance?

Singapore-dollar money placed under SRS with a bank in the scheme is covered by the Deposit Insurance Scheme, up to S$100,000 per depositor per bank. At DBS the cover is up to S$100,000 in aggregate per depositor per scheme member, so SRS cash shares the limit with your other SGD deposits at the same bank.

Foreign currency deposits, dual currency investments, structured deposits and other investment products are not insured. A money market fund or bond ETF bought with SRS money is an investment, so it sits outside the scheme. T-bills and SSBs fall outside it too, as obligations of the Singapore Government.

How to decide what to do with idle SRS cash

The years left before your prescribed retirement age set the outer limit. For a first contribution made from 1 July 2026, that age is 64, the statutory retirement age at the time of the first contribution. Money with 20 years to run can carry far more price risk than money you plan to start withdrawing in two.

Questions to answer first

When will you next move this money? If you are holding cash for an investment you plan to make within weeks, an SSB you can redeem in any month or a cash management portfolio fits better than a 1-year T-bill.

Can you accept a small dip in value? Deposits and government securities return your principal; funds and ETFs may not over short periods.

How big is the balance? Fixed charges such as the S$2 SSB fee or a per-order fee weigh more on small amounts than on large ones.

Do you want to act on every maturity? T-bills and fixed deposits need a new decision each time they mature. A portfolio or an SSB can run without one.

How much of your SRS is already in growth assets? Low-risk options suit the part of the balance you want to keep stable, while the long-horizon part can sit in diversified equity and bond portfolios.

When idle cash still makes sense

Some cash in SRS is unavoidable. Contributions often land in the last weeks of December, and a T-bill application or a platform transfer can take a few business days to settle. Holding cash for that short gap costs little: a month at 0.05% on S$15,300 earns about 64 cents, and the forgone T-bill interest over the same month is about S$25.

Put idle SRS cash to work with StashAway

For SRS cash you want to keep low risk while you decide what to do with it, StashAway Simple™ can be funded with SRS. It has a projected rate of 4.6% p.a. to 6.7% p.a. and a 0.15% p.a. management fee, and StashAway can request the money from your SRS bank on a schedule you set.

For the longer-term part of your SRS, ETF Explorer with SRS lets you choose US-listed and UCITS ETFs, bond ETFs included, for US$1 (excl. GST) per buy or sell order, with no monthly fee.

Simple's projected rate isn't guaranteed and ETF prices can fall, so you could get back less than you invest.

Frequently asked questions

Short answers on what SRS cash earns and what to do with it.

What does SRS money earn if I don't invest it?

It earns the operator bank's SRS deposit rate, which is 0.05% a year at DBS/POSB. On S$15,300, that comes to S$7.65 a year, and on S$100,000 it is S$50.

Do DBS, OCBC and UOB pay different SRS interest rates?

Each operator sets the rate on its own SRS accounts. DBS/POSB pays 0.05% a year, and POEMS gives the same 0.05% for SRS contributions kept in the bank.

Is SRS interest the same as CPF interest?

No. CPF savings earn CPF's rates, including a 2.5% floor on the Ordinary Account, while SRS cash earns the operator bank's deposit rate. The two schemes are separate, with different rules on contributions, investments and withdrawals.

How often is SRS interest credited?

Crediting follows the operator bank's schedule for the SRS account, and it shows up on your SRS statement. At 0.05%, how often it is credited makes little practical difference.

Is a money market fund bought with SRS capital guaranteed?

A money market fund is an investment, so its unit price can fall, though historical losses on short-duration cash portfolios have been small. It sits outside the Deposit Insurance Scheme even when bought with SRS money.

Does moving SRS cash into a fund or T-bill count as a withdrawal?

It doesn't. The purchase is paid from your SRS account and the proceeds of a sale or maturity return to it, so no tax or penalty applies. Tax arises only when money leaves the SRS account.

Can I lose my SRS tax relief by investing the cash?

Relief is based on the contribution itself, so investing the money has no effect on it. Relief is withheld only on amounts you contribute and then withdraw in the same year.
