Quick Comparison: GXS vs Trust Bank vs MariBank Rates

Here’s the short version. If you want the simplest account with no strings attached, MariBank’s flat 0.88% p.a. is hard to beat. If you’re willing to lock cash away, GXS pays more. If you can hit Trust Bank’s bonus conditions every single month, its Flex plan pays the most of the three.

The “up to” numbers you see in each bank’s marketing are best-case rates, not what most savers actually earn. That’s why we’ve broken out both the no-hoops rate and the maximum rate below.

GXS Bank Interest Rates Explained (August 2026)

GXS splits your money into three buckets, and each one earns a different rate. There’s no minimum balance and no fees on any of them.

Your Main Account earns 0.88% p.a., credited daily, and links to your GXS Debit Card for everyday spending. Saving Pockets earn 1.08% p.a. daily, with no lock-in — you can open up to 8 of them and withdraw anytime. The Boost Pocket pays the most, but you have to commit: choose a tenure of 1, 3, 4, 8 or 12 months, and you’ll earn 0.88% p.a. base interest daily plus bonus interest at maturity, from 0.13% p.a. (1-month) up to 0.72% p.a. (12-month).

You can open 5 Boost Pockets at once, with a combined deposit limit of S$95,000. There’s no salary crediting or minimum spend required to unlock any of these rates — that’s GXS’s whole pitch. For the full breakdown of Boost Pocket tenures and how the debit card cashback works, see our GXS Bank review.

Trust Bank Interest Rates Explained (August 2026)

Trust Bank works differently. You start with a 0.05% p.a. base rate, then pick a plan.

The Flex plan lets you choose any 3 of 8 “bonus scoops” each month — miss a scoop, and you lose that bonus interest for the month. The biggest scoops are: referring a new Trust credit card customer (+1.20% p.a.), investing at least S$20,000 in eligible TrustInvest funds (+0.70% p.a.), and crediting your salary via GIRO (+0.45% p.a.). Stack those three and you hit the full 2.40% p.a. on your first S$1.2 million.

If that sounds like too much admin, the Signature plan is the default you get if you don’t actively choose one. It caps out at 1.00% p.a. from salary crediting, a S$100K average daily balance, and card spending. The Zen plan is the no-strings option — a flat 0.40% p.a., nothing to unlock.

Realistically, most savers won’t hit all three of the highest-value scoops every month. Our Trust Bank interest rate breakdown walks through which scoop combinations are actually achievable for a typical household.

MariBank Interest Rate Explained (August 2026)

MariBank’s pitch is simplicity. The Mari Savings Account pays a flat 0.88% p.a. on your entire balance, credited daily. There’s no minimum deposit, no salary crediting, and no minimum spend — you just get the rate.

New customers get a temporary boost on top: an extra 1.60% p.a. for your first 30 days (capped at your first S$100,000), plus another 0.40% p.a. if you subscribe to ShopeeVIP. Add it up and new users can earn up to 2.88% p.a. — but only for that first month. After day 30, you’re back to the flat 0.88% p.a. base rate.

For SG readers who find GXS’s pocket system or Trust Bank’s scoops confusing, this flat-rate simplicity is the main draw. See our full MariBank interest rate guide for how the promo period is calculated day-by-day.

How Much You’d Actually Earn on S$20,000 (Worked Example)

Say you have S$20,000 sitting in a digital bank. Here’s what each one would actually pay you over a year, in two scenarios: doing nothing extra, and going all-in to hit the maximum rate.

Two things stand out. First, Trust Bank’s Flex plan pays the most in the best case — but only if you keep hitting scoops like the S$20,000 TrustInvest purchase every single month, which isn’t realistic for most people. Second, MariBank’s “up to 2.88% p.a.” only applies to new customers for 30 days, so don’t expect it as your ongoing rate.

For a saver who just wants their cash parked without any admin, GXS’s Saving Pocket and MariBank’s base rate are the two most realistic options — both comfortably beat the base rates most traditional bank savings accounts pay.

How to Choose Between GXS, Trust Bank and MariBank

There’s no single “best” digital bank — it depends on how much effort you want to put in and how you plan to use the account.

• Pick GXS if: you want daily interest with zero conditions on most of your cash, and don’t mind locking a portion away in a Boost Pocket for a higher rate.
• Pick Trust Bank if: you already spend on a Trust credit card, credit your salary via GIRO, or plan to invest through TrustInvest — the scoops you’d hit anyway.
• Pick MariBank if: you want the least complicated option, especially if you already shop on Shopee and want your savings account to just work without tracking bonus criteria.

Many Singaporeans actually hold accounts with all three, splitting cash to capture the best rate each bank offers for a specific purpose. Our GXS vs Trust Bank vs MariBank comparison goes deeper into features beyond just interest rates, like debit card perks and loan products.

Are Your Deposits Safe?

Yes. GXS, Trust Bank and MariBank are all full banks licensed by the Monetary Authority of Singapore (MAS), not fintech apps sitting on top of a bank. Your Singapore dollar deposits at each one are insured by the Singapore Deposit Insurance Corporation (SDIC) for up to S$100,000 per depositor, per bank.

That cap matters if you’re holding larger sums. If you have more than S$100,000 in total savings, consider spreading it across more than one bank to keep your full balance covered. If you’re weighing digital bank deposits against other low-risk options, our Singapore retirement calculator can help you figure out how much you actually need in cash versus invested assets.
