MariBank vs GXS Bank vs Trust Bank (2026): Which Digital Bank Is Actually Worth Opening — and Which Referral Bonus Is the Best First Step?

Every personal finance thread eventually asks the same question: MariBank, GXS, or Trust — which one should I actually open? The answer depends on what you want from a digital bank. But one thing all three have in common is that opening any of them for the first time usually comes with a sign-up bonus. This post covers the honest comparison and which starting path gives you the most.

​

First, How They Are Different as Banks

Singapore has five MAS-licensed digital banks in 2026. GXS Bank and MariBank hold Digital Full Bank licences and serve both individuals and businesses, while ANEXT and Green Link focus on SMEs. Trust Bank operates digitally under Standard Chartered's full bank licence. The three most relevant for everyday retail savers are MariBank, GXS, and Trust.

​

In mid-2026, Trust Bank leads with the highest potential savings rate at up to 2.40% p.a. — but only if you meet salary crediting and card spending conditions every month. GXS Bank offers 1.08% p.a. on Saving Pockets with no conditions (up to 1.6% on Boost Pocket with lock-in). MariBank pays a flat 0.88% p.a. with zero requirements, no minimum balance, no fall-below fee, and interest credited daily.

​

What that breakdown misses: a flat no-conditions rate is more predictable than a headline rate you might not consistently hit. Trust Bank's higher tier requires meeting specific thresholds every single month — miss one and you drop back to the base. MariBank's 0.88% is always there, regardless of how much you spend or where your salary lands.

​

The practical strategy most financially savvy Singaporeans use in 2026:

1. Trust Bank → if you can reliably meet its salary and spending conditions every month (up to 2.40% p.a.)
2. GXS Bank → to park up to S$95,000 at 1.08% with no conditions
3. MariBank → for additional savings up to S$100,000, Shopee integration, and a strong credit card

There is no penalty for holding all three. Many Singaporeans do.

How They Differ on Credit Cards

Singapore's three main digital banks collectively offer six consumer credit card products. MariBank's Mari Credit Card stands apart on three fronts:

• 1.5% unlimited cashback on all local spend, no minimum spend, no annual fee permanently
• 1.5 Shopee Coins per S$1 on purchases via Mari Credit Card Instant Checkout (equivalent to roughly 1.5% return on Shopee spend)
• Zero FX fees on overseas transactions using the Mastercard wholesale rate, valid until 31 December 2026

GXS does not offer a full credit card — its FlexiCard has no income requirement but caps all users at a S$500 credit limit. Trust Bank's Link and Freedom cards are competitive for NTUC and FairPrice regulars. For everyday flat cashback with no hoops, the Mari Credit Card is the most capable digital bank card currently available in Singapore.

​

How They Differ on ATM and Cash Access

This is where MariBank falls short and most posts skip it. MariBank provides no ATM withdrawal services — locally or overseas. Trust Bank supports ATM withdrawals at Trust and Standard Chartered ATMs across Singapore. GXS also has no ATM network.

​

If you need reliable cash access, keep at least one ATM-linked card from a traditional bank or Trust. MariBank functions best as a complementary digital account — not a standalone primary bank.

​

How They Differ on Overseas Transfers

This is a category where MariBank quietly outperforms. As at September 2026, MariBank's overseas transfer service reaches over 59 destinations in 21 currencies — including Malaysia, Indonesia, Japan, India, China, Philippines, South Korea, Vietnam, USA, Thailand, Hong Kong, and Taiwan. The S$0 Transfer Fee promotion is extended until 31 December 2026. GXS and Trust Bank do not currently match the breadth of this remittance network.

​

For Singaporeans who regularly send money across the Causeway or to family in Southeast Asia, MariBank's overseas transfer feature is a genuine advantage that most people discover only after they have already opened the account.

The Sign-Up Bonus Comparison

​

All three banks run referral and welcome programmes. In September 2026, MariBank's offering is the most structured and highest-value for new users who take the Credit Card Bundle path:

• S$15 referral cash (code 8ZUU96EA) — credited instantly on approval
• Up to S$100 in New to Card Rewards (S$30 welcome cashback + S$70 Shopee Voucher Pack) — triggered by qualifying spend in the first 30 days
• S$50 Salary Switch cash (concurrent promotion, 17 Aug–30 Sep 2026) — for new users who also credit salary of min. S$500

Total maximum for a new user who stacks all three: up to S$165 in one-time cash and vouchers, before any interest earned.

​

GXS and Trust run their own welcome promotions — check their respective apps for current figures. But for sheer new-user bonus potential in September 2026, MariBank's stack is hard to beat.

​

How to Claim the MariBank Referral Bonus (September 2026)

The September promotion closes 30 September 2026 and is capped at the first 10,000 successful referrals. Both limits are live — either can cut off access before month end.

1. Download the MariBank app (Apple App Store, Google Play, or Huawei AppGallery)
2. Tap Sign Up and register with a Singapore mobile number
3. Select Mari Credit Card Bundle during the application (S$15 referral cash vs S$10 for savings-only)
4. Enter 8ZUU96EA in the "Have a Referral / Promo Code?" field — before the Singpass step, not after
5. Complete Singpass / MyInfo verification and submit
6. Referral cash is credited to your Mari Savings Account instantly on approval

Bottom Line

MariBank is not the right sole bank for everyone. But for most Singaporeans who shop on Shopee, travel occasionally, or send money overseas — it earns its place alongside whatever primary account they already have. And September 2026 is one of the better months to open it, given the stacking potential across referral, salary switch, and credit card welcome promotions.
