TribeCar + MariBank + Trust Bank + FSMOne: The Zero-Fee Cash Buffer Before SRS Investing (2026)
Skipping car ownership with TribeCar can free up S$700-S$1,100 a month. Routing that cash through MariBank and Trust Bank first costs S$0 in fees while both stay SDIC-insured to S$100k each, and only the overflow into FSMOne SRS investing carries any fee at all — 0% on unit trusts, 0.08% (min S$8.80) on ETFs.

Why fee-free cash buckets come before any investing fee
Most TribeCar-plus-platform guides on this site rank destinations by rate, tax relief, or insurance cap. This one ranks them by a simpler question: what does it cost you to park the money here before you’ve earned a single dollar back?
MariBank and Trust Bank both charge zero account fees and zero minimum balance fees on their savings accounts. FSMOne charges 0% sales charge on unit trust SRS investing but does charge 0.08% (minimum S$8.80) on ETF trades. That makes the routing order obvious: fill the two fee-free, SDIC-insured buckets first, then let only the overflow — money you’ve decided you’re comfortable locking away for the long term — pay any fee at all.
Step 1: MariBank as the instant-access buffer
MariBank pays 0.88% p.a. on its savings account with no minimum balance and no monthly fee, and deposits are SDIC-insured up to S$100,000. A Singapore investor who frees up S$800/month by using TribeCar instead of owning a car can park the first tranche here with same-day PayNow access if an emergency hits. New sign-ups can use the MariBank referral code 2DCT80WQ for the current welcome offer.
Step 2: Trust Bank as the second SDIC-insured bucket
Trust Bank’s Flex plan advertises up to 2.40% p.a., but that headline needs S$20,000 invested through TrustInvest or a S$100,000 average daily balance. What’s actually achievable with three no-cost “scoops” — salary GIRO credit, five card transactions of S$30+, and a S$1,500 PayNow-linked balance — is closer to 0.85% p.a. (0.75% for non-union members). Trust Bank is a separate legal entity and separate SDIC Scheme member from Standard Chartered Bank (Singapore) Limited, so its S$100,000 insured cap doesn’t share with MariBank’s — together the two buckets insure up to S$200,000 in freed-up cash before a cent touches FSMOne. Sign up with the Trust Bank referral code HTWYQP95.
Step 3: FSMOne SRS once the cash buckets are full
Only once both fee-free buckets are topped up does the routing move to FSMOne (referral code P0544985) for SRS investing. FSMOne charges 0% sales charge on unit trusts inside an SRS account and 0.08% (minimum S$8.80) on ETF trades — the only fee anywhere in this four-platform chain. The SRS annual contribution cap remains S$15,300 for 2026, unchanged, and every dollar contributed reduces your assessable income for that tax year via IRAS‘s SRS relief scheme.
How much TribeCar actually frees up
Owning a car in Singapore typically costs S$700-S$1,100 a month once you add insurance, parking, petrol, and depreciation on a COE-priced vehicle, even before loan interest. TribeCar‘s pay-per-use model turns that fixed monthly cost into an as-needed expense — most users report freeing up the bulk of that S$700-S$1,100 range for savings and investing once they switch. Use the TribeCar referral code zZDeg for a sign-up credit on your first trip.
