GXS Bank, Trust Bank, and MariBank are Singapore’s three digital banks — all SDIC-insured, all mobile-first, and all competing for your savings. In mid-2026, GXS Bank leads with the highest no-conditions rate at 3.48% p.a., MariBank offers a solid 2.68% with zero requirements, and Trust Bank pays up to 2.40% but needs salary credit and card spending to hit its best rate. Your choice depends on how much you’re parking and whether you want a debit card.
This is an editorial comparison. Not financial advice. All figures are for educational reference only. Data as at July 2026 unless noted.
- GXS Bank pays the most (3.48%) with no conditions — best for pure cash parking up to S$75,000
- MariBank offers 2.68% flat with no hoops — simplest option, but has a S$75,000 cap and no debit card
- Trust Bank has the highest deposit cap (S$1.2M) and a useful debit card, but its base rate is just 0.05% without meeting salary and spend requirements
Quick Verdict
This three-way comparison gets asked on r/singaporefi nearly every week. The answer is simpler than you’d think.
GXS Bank wins on pure interest rate. 3.48% p.a. with absolutely no conditions — no salary credit, no card spend, no GIRO. Just deposit money and earn. The catch: S$75,000 cap.
MariBank is the simplest. 2.68% flat rate, no conditions, no hoops. Perfect for people who just want to park cash and forget about it. Same S$75,000 cap as GXS.
Trust Bank is the most “bank-like”. It has a credit card (linked to NTUC), a debit card, and the highest deposit cap at S$1.2 million. But without meeting salary and spend conditions, you earn a pitiful 0.05%.
Interest Rate Comparison
| Rate Component | GXS Bank | Trust Bank | MariBank |
|---|---|---|---|
| Base rate (no conditions) | 3.48% | 0.05% | 2.68% |
| With salary credit | N/A (no bonus tiers) | ~1.50% | N/A (no bonus tiers) |
| With salary + card spend | N/A | ~2.40% | N/A |
| Maximum rate | 3.48% | 2.40% | 2.68% |
| Deposit cap for best rate | S$75,000 | S$1,200,000 | S$75,000 |

The striking thing about this comparison is that GXS and MariBank are completely passive — you deposit and earn. Trust Bank’s competitive rate (2.40%) only appears when you meet salary credit and spending conditions, making it function more like a traditional bank’s bonus savings account.
Features & Products
GXS Bank
GXS Bank is backed by Grab and Singtel. Beyond savings, it offers FlexiLoan (personal loans via the Grab app), fixed deposits, and a Visa debit card. GXS FlexiLoan interest rates are competitive for small personal loans. The Grab integration means you can use GrabPay and GXS together for a seamless experience. Use a GXS referral code for sign-up bonuses.
Trust Bank
Trust Bank is backed by Standard Chartered and FairPrice Group (NTUC). It offers the most traditional banking experience among the three — Mastercard debit card, a credit card linked to NTUC rewards (earn LinkPoints on FairPrice purchases), and a generous deposit cap of S$1.2 million. It’s the only digital bank that accepts foreigners. Sign up with a Trust Bank referral code for bonus rewards.
MariBank
MariBank is owned by Sea Group (Shopee’s parent). It’s the most stripped-down of the three — savings account and personal loans only. No debit card, no credit card, no fixed deposits. The appeal is purely the 2.68% flat rate with zero conditions. If you want a bank that does exactly one thing well, MariBank is it. Get extra cashback with a MariBank referral code.
Deposit Caps (This Matters More Than Rates)
The most overlooked factor in digital bank comparisons isn’t the interest rate — it’s how much money you can actually put in.
GXS and MariBank both cap at S$75,000. That means if you have S$100,000 in savings, you can’t park all of it in either bank. You’d need to split it across multiple banks.
Trust Bank, with its S$1.2 million cap, solves this — but only if you meet the conditions for the higher rate. At the base rate of 0.05%, you’d earn just S$50/year on S$100,000. That’s worse than a traditional DBS savings account.
For most Singaporeans with S$20,000–S$75,000 in savings, GXS is the clear winner. For amounts above S$75,000, you’ll need a multi-bank strategy — perhaps GXS (first S$75,000) + MariBank (next S$75,000) + a traditional bank for the rest.
Who Backs Each Bank?
All three digital banks are licensed by MAS and your deposits are insured by SDIC up to S$100,000 — the same protection you get at DBS, OCBC, or UOB.
| Bank | Parent / Backer | Licence Type | Key Risk Factor |
|---|---|---|---|
| GXS Bank | Grab + Singtel (60/40) | Digital Full Bank | Grab’s profitability journey |
| Trust Bank | Standard Chartered + NTUC | Full Bank | StanChart is a 170-year-old bank — low risk |
| MariBank | Sea Group (Shopee, Garena) | Digital Full Bank | Sea’s volatile earnings history |

Trust Bank has the most conservative backing — Standard Chartered is a global bank with 170 years of history. GXS and MariBank are backed by tech companies (Grab/Singtel and Sea respectively), which carry slightly more business risk. However, SDIC insurance means your deposits are protected regardless of the parent company’s fortunes.
Earnings Comparison by Balance
| Balance | GXS (3.48%) | Trust Bank (0.05% base) | Trust Bank (2.40% max) | MariBank (2.68%) |
|---|---|---|---|---|
| S$10,000 | S$348 | S$5 | S$240 | S$268 |
| S$25,000 | S$870 | S$12.50 | S$600 | S$670 |
| S$50,000 | S$1,740 | S$25 | S$1,200 | S$1,340 |
| S$75,000 | S$2,610 | S$37.50 | S$1,800 | S$2,010 |
Source: Calculated from published rates, July 2026. Trust Bank shows both base rate (no conditions) and maximum (with salary + spend).
The numbers tell a stark story. At S$50,000, GXS earns you S$1,740 versus Trust Bank’s S$25 (without conditions) or S$1,200 (with conditions). That’s a S$540 difference between GXS and even Trust Bank’s best rate.
If you’re using digital banks purely to earn interest on idle cash — which is what most people do — GXS wins at every balance up to its S$75,000 cap. Use a retirement calculator to see how digital bank savings fit into your long-term plan.
Referral Bonuses
All three digital banks offer sign-up bonuses. These change monthly, so check the latest before opening your account.
Use our referral codes for the best current bonuses: GXS Bank referral | Trust Bank referral | MariBank referral
The sign-up bonuses are a nice one-time perk, but don’t let them sway your decision — the ongoing interest rate difference matters far more over a year than a one-time S$10–S$20 bonus.
TKN’s Take
Open all three. Seriously. They’re all free, take 5 minutes to set up, and have no fees.
The optimal strategy for most Singaporeans in 2026: park your first S$75,000 in GXS (earning 3.48%), your next S$75,000 in MariBank (earning 2.68%), and use Trust Bank for its debit card and NTUC credit card perks. If you have more than S$150,000 in cash, the excess should go into a Singapore Savings Bond or T-bills rather than sitting in any savings account.
If you can only open one, choose GXS Bank. The 3.48% with no conditions is the best liquid savings rate available in Singapore right now.
