TribeCar + MariBank + Syfe + Trust Bank + IBKR: Stacking Every Referral Bonus in 2026

The exact order to claim five sign-up bonuses — from a free S$20 in two minutes to a US$1,000 IBKR stock reward that takes real capital.

TribeCar, MariBank, Syfe, Trust Bank, and IBKR each run a referral programme, and signing up to all five with the right code — zZDeg, 2DCT80WQ, SRPRFFFCD, HTWYQP95, and jianxiong368 — can be worth over S$1,500 in combined rewards. The catch is that the biggest payouts need real capital and patience, so the right order is: free ones first (TribeCar, MariBank), small-funding ones next (Syfe), then the two that need committed deposits (Trust Bank, IBKR) last.

What Each Referral Bonus Is Actually Worth

Referral pages love to headline the biggest possible number. In practice, each platform has a “realistic” tier you get almost immediately with little or no deposit, and a “maximum” tier that needs real funding and time. Here’s the honest breakdown as at October 2026:

Source: TribeCar, MariBank, Syfe, Trust Bank and IBKR referral programme terms, verified by The Kopi Notes, October 2026. Figures are indicative — always confirm current terms before funding an account.

Step 1: TribeCar (Code zZDeg) — Claim First, Zero Cost

Start here because it costs nothing and takes under two minutes. Download the TribeCar app, sign up with your email and mobile number, then go to Profile → Referral Code and enter zZDeg before your first booking. You’ll get S$20 off your first car-sharing trip — no deposit, no KYC beyond a driving licence check, and no ongoing commitment. If you don’t drive, you can skip straight to Step 2; nothing downstream depends on this one.

What makes TribeCar a good opener for a bonus-stacking run: the savings from skipping car ownership (no down payment, no road tax, no insurance, no depreciation) is itself the single largest lever in most Singapore households’ budgets, and that freed-up cash is what funds Steps 3-5 below. See our TribeCar bonus-stacking sequence guide for a deeper look at timing promotional windows across platforms.

Step 2: MariBank (Code 2DCT80WQ) — Claim Second, No Deposit

MariBank, Grab’s digital bank, is the second free step. Sign up via Singpass MyInfo (about five minutes), enter referral code 2DCT80WQ during registration, and S$10 cash lands in your Mari Savings Account instantly — no minimum deposit required. Opening a Mari Invest bundle alongside the savings account can push the combined welcome credit toward S$15, but that’s optional and not required to bank the S$10.

MariBank’s base savings rate (0.88% p.a.) is unremarkable on its own, but as a same-day parking spot for the cash you haven’t yet routed to Steps 3-5, it beats letting money sit idle in a current account at 0.05%.

Step 3: Syfe (Code SRPRFFFCD) — Small Funding Unlocks More

Syfe is where the ladder starts asking for capital. Signing up with referral code SRPRFFFCD gets you a sign-up reward on your account with no funding required. But Syfe’s bigger tiers are funding-linked: Brokerage cash credits scale from roughly S$20 at a S$2,000–S$4,999 one-time deposit up to S$450 at S$100,000+, and Managed Portfolios can earn up to 12 months of management fee waiver depending on the promotion live when you sign up. The qualifying deposit must land within 30 days of applying the code, so don’t claim it until you’re ready to fund.

A practical middle ground: fund Syfe with whatever you’d already planned to invest this quarter (e.g. topping up a Cash+ or Income+ allocation) rather than depositing extra cash purely to chase a higher tier — the fee-waiver and cash-credit tiers are a bonus on top of money you were moving anyway, not a reason to over-allocate.

Step 4: Trust Bank (Code HTWYQP95) — Spend-Linked, Takes Longer

Trust Bank’s welcome rewards are the least “instant” of the five. Entering HTWYQP95 at sign-up typically unlocks a scratch-card style welcome credit (around S$5–S$18 guaranteed, occasionally higher), but the headline “up to S$1,000” figure tied to the Trust Bank Freedom Card requires sustained card spend and cashback-qualifying transactions over months, not a one-time action. Treat the scratch-card portion as the realistic bonus and the S$1,000 figure as a ceiling you reach only if you were going to use the Freedom Card as a daily driver anyway.

This is also the step where “achievable rate” matters more than headline rate — Trust Bank’s advertised savings rate needs several linked scoops (salary credit, card spend, PayNow) to hit, which we break down fully in our TribeCar + MariBank + Trust Bank + GXS + IBKR SDIC-ladder guide.

Step 5: IBKR (Code jianxiong368) — The Capital-Heavy Finish

Interactive Brokers is last because it has the largest ceiling and the largest commitment. Apply with referral code jianxiong368, then deposit at least US$10,000 within 30 days of account opening and keep that balance for a full year to earn up to US$1,000 in free IBKR stock (roughly S$1 in stock for every US$300 deposited). There is no realistic “free” tier here — if you don’t have US$10,000 you’re comfortable locking up for a year, this step simply doesn’t apply to you yet, and that’s fine; the first four steps alone are worth claiming on their own.

The Effort-to-Reward Ladder, Visualised

Lay the five bonuses out by effort and a clear pattern emerges: the first two steps are pure upside (zero cost, under 10 minutes combined, S$30 guaranteed), the middle step rewards money you were investing anyway, and the last two only pay out at scale if you were already going to spend on a Trust Bank card or park US$10,000 somewhere for a year. Don’t fund Trust Bank or IBKR just for the referral bonus — claim them when the underlying decision (which card to carry, where to hold USD-denominated savings) was already in your plan.

Who Should Skip Which Step

Not every step suits every reader, and forcing all five is the wrong move for most people:

Skip TribeCar if you already own a car or never rent one — there’s no substitute bonus, just move on.

Skip MariBank only if you’ve already banked its welcome bonus under a different referral in the past; MariBank’s terms generally bar repeat bonuses on the same NRIC.

Skip Syfe funding beyond the sign-up tier if you don’t already have an investing plan this quarter — don’t create new capital just to chase a cash-credit tier.

Skip Trust Bank’s card-spend chase if you’re not planning to switch your primary spending card; the scratch-card alone is worth claiming regardless.

Skip IBKR entirely if US$10,000 isn’t money you can set aside for 12 months without needing it — the bonus isn’t worth locking up an emergency fund or near-term savings for.

The Bottom Line

Claim TribeCar and MariBank today — they’re free. Add Syfe when you next top up an investment you’d already planned. Save Trust Bank and IBKR for when the underlying decision (daily spending card, long-term USD broker) is one you were making anyway. Stacked in that order, five unrelated referral programmes turn into one coherent plan instead of five separate chores.
