I Signed Up for All Three Singapore Digital Banks — Here's Where Trust Bank Actually Pulls Ahead (and Where It Doesn't)

Everyone asks "which digital bank should I pick" like there's one right answer. Having actually used Trust, MariBank, and GXS side by side for a while now, the honest answer is that they're built for different habits, not competing head-to-head on the same thing. Here's where each one actually wins, starting with the referral angle since that's usually what brings people here in the first place.

​

Referral rewards, compared honestly

Trust Bank's referral mechanic is a scratch card, not a fixed number — S$50 to S$8,000 if your friend signs up for a credit card, S$8 to S$1,888 for a savings account, and your friend separately gets their own sign-up gift (currently up to S$8,000 cash, running until 31 Oct 2026). Use code 2GG9T8K3 if you're trying it.

MariBank runs flatter, guaranteed tiers instead — currently S$8 for a Savings Account/Invest Bundle and S$15 plus up to S$100 in extra rewards for their Credit Card Bundle. No lottery element, just fixed cash.

​

GXS doesn't run a consistent guaranteed-tier referral structure the way the other two do right now — worth checking their live in-app terms if you're specifically chasing their current promo.

​

If you want certainty, MariBank's flat structure is more predictable. If you want upside and don't mind variance, Trust's scratch card mechanic has a genuinely higher ceiling.

​

Where each bank actually wins day-to-day, beyond the sign-up bonus

Trust Bank pulls ahead if:

• You shop FairPrice, Unity, or Cheers regularly (Link Card's grocery savings)
• You want to dollar-cost-average into US stocks through everyday spend (Freedom Card's Stockback option)
• You want your savings account rate to respond to your own activity — the Flex plan's 8 bonus scoops, including a genuinely large +1.20% p.a. for referring a credit card customer, let you push toward 2.40% p.a. without locking up a huge balance

MariBank pulls ahead if:

• You want the simplest possible flat-rate cashback card with no categories to think about (1.5% unlimited)
• Zero FX fees plus bonus cashback on overseas spend specifically matters to you
• You'd rather have guaranteed cash than a scratch-card range

GXS pulls ahead if:

• You run a small business or freelance operation and want banking built around that, via GXS FlexiLoan and business-focused features
• You're less interested in credit card ecosystems and more in straightforward digital banking utility

A genuinely fair point: you don't have to pick just one

I hold accounts at all three, and there's no rule against it — referral programmes are bank-specific, so a Trust scratch card and a MariBank flat cash reward can both land in the same month if you qualify for each. The only real cost is more apps to check and slightly more mental overhead tracking which card earns what where.

If you're starting with Trust Bank

1. Download the Trust Bank SG app
2. Enter referral code 2GG9T8K3 at the very first "Get Started" screen
3. Apply for whichever product fits — Freedom Card if you want flexible rewards, Link Card if FairPrice is a big part of your spend, Savings Account if you're not ready for a credit card yet

👉 Referral Code: 2GG9T8K3

Genuinely open to hearing if anyone's found GXS running a comparable guaranteed-tier promo recently — that's the one leg of this comparison I have the least current visibility into.
