What Changed This Month

If you opened a Trust Bank account earlier in 2026 and picked the Zen plan for its “no strings attached” simplicity, check your rate. As at August 2026, Zen pays a flat 0.40% p.a., not the 0.50% p.a. that was advertised as recently as June 2026.

You didn’t do anything wrong. Trust Bank adjusts its base and bonus rates from time to time, the same way DBS or OCBC revise their bonus savings tiers. The change just doesn’t always make headlines.

MariBank’s move is bigger. Its flat, no-conditions savings rate has fallen from 2.68% p.a. (a promotional-era high) to a base rate of 0.88% p.a., effective 1 June 2026 according to MariBank’s own fees and rates page. If you’re still comparing digital banks using older figures floating around online, you’ll want to update your numbers.

Trust Bank’s Three Plans, Updated

Trust Bank lets you choose (and switch, every month, for free) between three savings plans. Here’s exactly how each one works as at August 2026.

Flex Plan — up to 2.40% p.a.

You start with a 0.05% p.a. base rate, then pick any 3 of 8 “scoops” (Trust Bank’s term for bonus interest categories) to unlock each month:

You choose your best 3 categories each month. For most people without S$20,000 to invest or a friend to refer, the realistic combo is Salary (+0.45%) + Balance (+0.30%) + Spend (+0.20%), which gets you to 0.05% + 0.95% = 1.00% p.a. — the same ceiling as the Signature plan below.

Signature Plan — up to 1.00% p.a.

This is the default plan if you don’t actively choose one. It locks you into a fixed set of bonus categories rather than letting you pick: salary credit (+0.45%), Average Daily Balance of S$100,000 (+0.30%), and card spend (+0.20% or +0.10%), on top of the 0.05% base — capping out at 1.00% p.a.

Zen Plan — flat 0.40% p.a.

No salary crediting, no card spend, no minimum balance. You just deposit and earn 0.40% p.a. on your full balance, up to the S$1.2 million cap. This is down from 0.50% p.a. earlier in 2026 — still the simplest option, just a slightly lower one now.

How Trust Bank Compares to GXS and MariBank Now

The picture has shifted since earlier in the year. GXS Bank’s 1.08% p.a. no-conditions rate on Saving Pockets is now the highest passive rate among the three digital banks — you don’t need to lift a finger to earn it. MariBank’s 0.88% p.a. sits just behind, also with zero conditions. Trust Bank’s no-conditions Zen rate, at 0.40% p.a., is now the lowest of the three passive options, though its Flex plan still offers the highest ceiling overall if you’re willing to meet the bonus criteria.

For context on how these banks differ beyond rates — deposit caps, debit cards, and who’s behind each one — see our full GXS vs Trust Bank vs MariBank comparison.

Which Trust Bank Plan Should You Pick?

Here’s how to think about it based on your situation, not just the headline rate.

Choose Flex if: You already credit your salary to Trust, keep a S$100,000+ balance, or spend regularly on the Trust card. Stacking 3 categories gets you close to or at the 2.40% p.a. ceiling for free — you’re already doing most of the work.

Choose Zen if: You want a “set and forget” account and don’t want to track monthly conditions. At 0.40% p.a., it’s now roughly on par with a basic OCBC or DBS savings account, but with a much higher S$1.2 million balance cap and no fall-below fees.

Choose Signature if: You meet the salary, balance and spend criteria consistently but don’t want to think about which 3 scoops to pick each month. It’s the “default” for a reason — steady, if slightly lower than the top end of Flex.

If you’d rather park cash somewhere with zero moving parts and a slightly higher passive rate, GXS Bank’s 1.08% p.a. Saving Pocket is worth a look — though its S$95,000 cap means Trust Bank still wins for larger balances. See our GXS Bank review for the full picture.

What This Means for Your Savings

None of these are dramatic cuts on their own. But if you’re holding a meaningful cash balance, a 0.10 to 1.80 percentage point swing adds up. On S$50,000, the difference between MariBank’s old 2.68% p.a. and its current 0.88% p.a. is about S$900 a year in foregone interest.

Two practical takeaways. First, re-check your digital bank’s current rate every few months — these platforms adjust rates more frequently than traditional banks, often without a press release. Second, if you’re chasing the highest possible rate and don’t mind meeting a few conditions, Trust Bank’s Flex plan (up to 2.40% p.a.) is still the strongest option among Singapore’s three digital banks, provided you can hit 3 of the 8 bonus categories.
