Quick Answer: Which Digital Bank Pays the Most Right Now?

It depends on your balance and how new you are to the bank. If you’ve never had a MariBank account, its 2.88% p.a. new-user rate is the highest headline number — but only for 30 days and only on your first S$100,000. If you want a rate that lasts all year, Trust Bank’s Flex plan tops out at 2.40% p.a., as long as you hit 3 of its 8 bonus conditions every month. If you just want simple, no-conditions interest with no expiry date, GXS Bank’s Saving Pockets pay a flat 1.08% p.a. with zero hoops.

Here’s the honest takeaway: none of these banks pay their top rate on a large, permanent balance without some kind of catch. Read on for the exact numbers, because the small print matters more than the headline percentage.

Key Differences at a Glance

GXS Bank: Rates & Promos This Month

GXS Bank splits your money into three “pockets.” Your Main Account pays 0.88% p.a. and works like a normal spending account. Your Saving Pockets pay a flat 1.08% p.a. with no lock-in and no minimum balance — you can open up to 8 of them. Your Boost Pockets pay a base 0.88% p.a. plus a bonus for locking funds in for a set tenure, topping out at 1.60% p.a. for a 12-month lock.

Right now, GXS is running two live promotions. Its National Day campaign (valid till 18 August 2026) gives you S$10 cashback for every S$10,000 you deposit into a 12-month Boost Pocket named “SG61” — that works out to an effective rate of about 1.70% p.a. For brand-new users, the “First Boost” promo pays S$20 cashback on your first S$5,000 deposited into a 3-month Boost Pocket, which annualises to roughly 2.82% p.a. GXS also runs an ongoing referral scheme paying S$8 for every friend who signs up, active until 31 December 2026.

Trust Bank: Rates & Promos This Month

Trust Bank’s savings account now runs on three plans instead of one flat rate. The Flex plan starts with a 0.05% p.a. base rate, then lets you pick any 3 of 8 monthly “scoops” — things like crediting your salary (+0.45%), spending S$150 across 5 transactions (+0.20% for NTUC Union members, +0.10% otherwise), keeping a S$100,000 average daily balance (+0.30%), or referring a new credit card customer (+1.20%). Stack the right 3 and you reach 2.40% p.a.

If you don’t actively choose a plan, Trust defaults you to the Signature plan, which caps out at just 1.00% p.a. There’s also a Zen plan for people who want zero conditions — it pays a flat 0.40% p.a. with nothing to do. Trust’s separate Trust+ tier goes further, but it needs a minimum S$100,000 balance across your Trust savings and TrustInvest accounts, so it’s really a different product for larger savers.

The trade-off is clear: Trust’s top rate needs the most ongoing effort of the three banks, but unlike GXS and MariBank’s promos, it isn’t a temporary campaign — it’s baked into the product every month, for as long as you keep meeting the conditions.

MariBank: Rates & Promos This Month

MariBank keeps things simple with one Mari Savings Account. The base rate is 0.88% p.a. on your full balance, no minimum deposit and no conditions attached. On top of that, new users get a 30-day welcome bonus of +1.60% p.a. (capped at your first S$100,000), and anyone subscribed to ShopeeVIP earns another +0.40% p.a. Stack all three and MariBank’s maximum advertised rate is 2.88% p.a. — but remember, the 1.60% new-user chunk disappears after 30 days, dropping you back to 0.88% (or 1.28% with ShopeeVIP).

MariBank charges no account fees, no fall-below fees and currently waives overseas transfer fees under a promotion running until 31 December 2026.

Real SGD Comparison: What You’d Actually Earn

Percentages are easy to skim past. Here’s what they mean in real money for a Singapore saver with S$20,000 to park somewhere.

Put S$20,000 into a GXS 12-month Boost Pocket at the combined 1.60% p.a. rate, and you’d earn about S$320 in interest over the year. Put the same S$20,000 into a Trust Zen account at a flat 0.40% p.a. with zero effort, and you’d earn just S$80 — a S$240 gap for doing almost nothing differently, just picking the right product.

Now stretch that S$20,000 across MariBank’s 30-day welcome window at 2.88% p.a.: you’d earn roughly S$46 in that first month alone. But once the promo ends and you’re back to the 0.88% base rate, the same S$20,000 earns about S$14.70 a month — a big step down. That’s the catch with headline “new user” rates: they look great in the first line of an ad, but they’re not what you’ll actually earn most of the year.

If you can consistently hit 3 of Trust’s 8 monthly scoops — say, salary crediting plus card spend plus a S$100,000 average balance — a S$100,000 deposit at 2.40% p.a. earns about S$2,400 a year, before accounting for any TrustInvest or credit card activity needed to unlock those bonuses.

Who Should Pick Which Digital Bank?

GXS Bank is ideal if you want daily interest with zero conditions, don’t mind splitting savings across pockets, and you’re comfortable with a S$95,000 deposit cap. It suits people who want a “set and forget” account without chasing salary-crediting rules.

Trust Bank is ideal if you already bank with Standard Chartered or shop regularly at FairPrice, NTUC or Unity, and you’re willing to actively manage 3 monthly conditions for a rate that doesn’t expire after a promo period.

MariBank is ideal if you’re a brand-new digital bank customer looking for the highest short-term rate, you shop on Shopee, or you send money overseas often and want the fee waiver. It’s less ideal as a long-term primary account once the welcome bonus runs out.

None of these accounts are eligible for CPF investment, and all three are separate from your CPF investment strategy — treat them purely as cash management tools for money you might need on short notice.

How to Open a Digital Bank Account in Singapore

All three banks let you apply fully online through their app, using Singpass MyInfo to verify your identity — no paperwork needed. You’ll need to be a Singapore Citizen, Permanent Resident, or a foreigner holding a valid pass, and be at least 16 (MariBank) or 18 (GXS, Trust) years old.

1. Download the bank’s app (GXS Bank, Trust, or MariBank) from the App Store or Google Play.
2. Register using your Singapore mobile number.
3. Verify your identity via Singpass MyInfo — this pulls your details automatically.
4. Fund your account via PayNow or FAST transfer from an existing bank.
5. If you’re chasing a promo rate, check the specific terms (named pocket, referral code, minimum hold period) before you transfer funds.
