Endowus lets you invest your CPF-OA, SRS, and cash into low-cost funds, while Trust Bank pays you more interest on everyday savings than a standard bank account. Pairing them means your long-term CPF/SRS money grows through Endowus’s fund access, and your short-term cash still earns a tiered savings rate through Trust Bank, without locking up money you need on hand.

Why pair Endowus with Trust Bank?

Most people treat “where do I put my money” as one decision. It’s actually two. Your CPF-OA and SRS money is locked away for years, so it should be working hard for growth. Your everyday cash needs to stay liquid, so it should still earn a decent rate while sitting there.

Endowus solves the first problem. It lets you invest your CPF Ordinary Account (CPF-OA), Supplementary Retirement Scheme (SRS) funds, and plain cash into institutional-class unit trusts — at a fraction of what a bank would charge you for the same funds.

Trust Bank solves the second. It’s a digital bank backed by Standard Chartered and FairPrice Group, offering tiered savings interest and cashback that beats most traditional banks, with no lock-in and instant access.

Used together, you get one platform working on your long-term retirement money and another keeping your short-term cash productive. Neither platform tries to do the other’s job — and that’s exactly why the combo works.

What Endowus does for your CPF-OA, SRS and cash

Endowus is a robo-advisor regulated by the Monetary Authority of Singapore (MAS). It gives you access to unit trusts from managers like Dimensional, PIMCO, and Fullerton — the same funds that used to be reserved for institutional or private banking clients.

Here’s what you can do with it:

• CPF-OA investing: Your CPF-OA earns 2.5% guaranteed. Endowus lets you invest a portion into diversified funds that have historically returned more over the long run — though unlike CPF-OA, this return is not guaranteed and can go down.
• SRS investing: Money sitting in your SRS account earns almost nothing if left as cash. Endowus lets you put it to work in equity and bond funds while you still enjoy the SRS tax relief.
• Cash Smart: For money you don’t want locked into CPF or SRS rules, Endowus’s Cash Smart portfolios invest in short-duration bond and money market funds, aiming for a yield above typical savings rates.

You can sign up with the Endowus referral code and sign-up bonus using code 2V343, which gets you fee credits on qualifying investments.

What Trust Bank does for everyday spending and saving

Trust Bank is the digital bank that grew fastest in Singapore after launch, largely because it’s tied to FairPrice — Singaporeans already shop there weekly. It’s fully MAS-regulated and covered by SDIC insurance up to S$100,000 per depositor.

What makes it useful in this combo:

• Tiered savings interest: Your base rate rises the more you spend on your Trust debit card and the more products you hold with them (like insurance or investments), up to a capped balance.
• No lock-in: Unlike a fixed deposit or SSB, your cash stays fully liquid. You can withdraw or spend it any time.
• FairPrice rewards: Card spend earns linkpoints redeemable at NTUC FairPrice, on top of the cashback most digital banks already offer.

This is the account for your emergency fund, short-term savings goals, or cash you’re not ready to commit to Endowus’s Cash Smart. You can open one using the Trust Bank referral code HTWYQP95 for a sign-up bonus.

Rates and fees compared

Here’s how the two platforms stack up on cost and return potential. Endowus figures are indicative fund yields, not guaranteed. Trust Bank’s rate depends on your card spend and product tier.

Worked example: $20,000 CPF-OA + $5,000 cash

Say you have $20,000 in CPF-OA earning the standard 2.5%, and $5,000 in cash sitting in a regular bank account earning close to nothing. Here’s how a 5-year projection compares if you moved that CPF-OA into an Endowus fund and that cash into Trust Bank.

Over 5 years, the CPF-OA portion could end up roughly $3,477 higher through Endowus versus leaving it untouched — though this is not guaranteed, since fund returns can be lower or even negative in some years. The cash portion in Trust Bank could earn roughly $508 more than sitting in a near-zero bank account, with none of that money locked up.

However, keep in mind: the past does not predict the future. Endowus fund performance depends on markets. Trust Bank’s tiered rate depends on maintaining card spend and product criteria — read the fine print before assuming you’ll hit the top tier.

How to set up the combo, step by step

1. Open your Trust Bank account first. It takes minutes via Singpass. Use referral code HTWYQP95 at sign-up to qualify for the welcome bonus, and set it as the destination for your everyday spending and emergency fund.
2. Link your debit card as your main spending card for at least a month to start climbing the interest tiers before you judge the rate.
3. Sign up for Endowus separately using referral code 2V343. You’ll need Singpass MyInfo and your CPF/SRS account details if you’re investing those.
4. Decide how much CPF-OA you’re comfortable investing. A common approach is to keep 1–2 years of near-term needs (like a home loan buffer) in CPF-OA and invest the rest.
5. Pick a fund tier or portfolio that matches your risk appetite — Endowus offers ready-made portfolios if you don’t want to pick individual funds.
6. Review both accounts quarterly. Rebalance Endowus if your risk profile changes; check you’re still hitting Trust Bank’s top interest tier.

Who this strategy suits

This combo works best if you’re a working adult with CPF-OA or SRS balances you’re not touching for years, and separately you keep a cash buffer for near-term spending. If you have no CPF-OA to spare, or you need every dollar liquid, skip the Endowus side and just use Trust Bank.

It’s not for you if you’re close to using your CPF-OA for a property purchase in the next 1–2 years — market-linked investments can dip right when you need the cash.

Risks and caveats

Endowus fund investments are not principal-protected. You could get back less than you put in, especially over shorter time horizons. CPF-OA’s 2.5% is guaranteed by the government — investing it means giving up that guarantee for a shot at a higher, uncertain return.

Trust Bank’s advertised rate is usually the top tier, which requires meeting spend or product conditions. If you don’t meet them, your actual rate could be lower than expected.
