moomoo Cash Plus Review Singapore 2026: Is It Worth Using?
Updated June 2026 · Digital Banks · 8 min read
moomoo Cash Plus is a cash management feature inside the moomoo Singapore brokerage app. It lets you park your idle cash in SGD or USD money market funds (MMFs), earning a variable yield with no minimum amount, no fees, and same-day or next-day redemption. As of May 2026, the underlying Fullerton SGD Cash Fund yields approximately 1.32% p.a. — lower than MariBank (2.68%) or GXS Bank (3.00%), but useful for keeping your investing capital working between trades.

- moomoo Cash Plus invests your idle brokerage cash in money market funds — it’s not a savings account.
- Current SGD yield (~1.32% p.a.) is lower than GXS Bank (3.00%) or MariBank (2.68%) — but Cash Plus is designed for cash sitting in your brokerage, not as a primary savings vehicle.
- If you’re already using moomoo to invest, Cash Plus is a no-brainer way to earn something on uninvested funds. For your main savings, the digital banks win on rate.
What is moomoo Cash Plus?
moomoo Cash Plus is a cash management product built into the moomoo Singapore brokerage app. It’s not a savings account — it’s a way to subscribe to money market funds (MMFs) directly from your moomoo universal account.
Money market funds (MMFs) invest in very short-term, low-risk instruments: government treasury bills, fixed-time bank deposits, and highly rated corporate bonds with maturities under one year. They’re designed to be stable — but returns are not guaranteed and they’re not protected under the Singapore Deposit Insurance Corporation (SDIC).
moomoo offers two cash management products:
- Cash Plus — invests in SGD or USD money market funds. High liquidity: redeem on T+0 or T+1. Designed for cash you may need quickly for trading.
- Income Plus — invests in short-term bond funds (duration up to ~2 years). Higher potential yield, but redemption takes up to T+6 business days.
This article focuses on Cash Plus — the more liquid of the two.
How does moomoo Cash Plus work?
When you subscribe to Cash Plus, you’re buying units in a money market fund — not depositing money into a bank. Your funds move from your moomoo account into the chosen MMF. The fund earns income daily from the instruments it holds, and this income is credited to your holding every trading day.
When you want to trade, you redeem your Cash Plus holding. For the SGD fund, redemption typically completes on T+0 or T+1. Once redeemed, you can immediately use the funds to buy stocks, subscribe to IPOs, or invest in other funds.
Which funds are available?
The main SGD fund is the Fullerton SGD Cash Fund, managed by Fullerton Fund Management — a subsidiary of Temasek Holdings. The funds invest in: Singapore government short-term securities, fixed-time bank deposits with local and international banks, and highly rated short-term corporate debt.
Is your money safe in Cash Plus?
Your cash is segregated from moomoo’s own assets under MAS regulations — the platform cannot misuse your money. However, Cash Plus is not covered by SDIC deposit insurance. In practice, SGD money market funds are designed to maintain a stable Net Asset Value (NAV), but there is no absolute guarantee of capital.
Current yield and returns — what can you actually earn?
This is where moomoo Cash Plus is often misunderstood. The platform has run promotions offering “up to 6.8% p.a.” — but that’s a limited-time cash top-up from moomoo, not the underlying fund yield. The fund itself earns much less in the current rate environment.
As of May 2026, the Fullerton SGD Cash Fund had a 7-day annualised yield of approximately 1.32% p.a. Money market fund yields track short-term interest rates closely. As SORA has fallen from its 2023–2024 highs, MMF yields have compressed significantly.

If you parked S$10,000 in Cash Plus at 1.32% p.a., you’d earn roughly S$132 per year. Compare that to GXS Bank (3.00% = S$300/year) or MariBank (2.68% = S$268/year). The gap is meaningful for larger balances.
| Platform | Rate (% p.a.) | Annual return on S$10k | SDIC Protected? |
|---|---|---|---|
| moomoo Cash Plus | ~1.32%* | ~S$132 | ✗ No |
| Trust Bank | 2.40% | S$240 | ✓ Yes |
| MariBank | 2.68% | S$268 | ✓ Yes |
| GXS Bank | 3.00% | S$300 | ✓ Yes |

The rate gap is real. So why use Cash Plus? It’s designed for cash inside your brokerage — not your primary savings. Between trades, your brokerage cash would otherwise earn zero. Cash Plus earns you something on that float, with the convenience of instant redeployment into your next trade.

Let’s put them side by side. These are fundamentally different products solving different problems.

When Cash Plus beats the digital banks
The scenario where Cash Plus makes sense: you’re an active investor using moomoo to buy stocks or ETFs. Between trades, your brokerage account holds cash waiting to be deployed. Without Cash Plus, that earns zero. With it, it earns ~1.32% p.a. while remaining accessible by the next day.
Transferring money to a digital bank and back each time you want to trade creates friction — delays and manual steps. Cash Plus removes that friction entirely. Think of it as the passive income layer for your brokerage idle cash.
When the digital banks win
For your core savings — the emergency fund and money for near-term goals — GXS Bank (3.00%) or MariBank (2.68%) are clearly better. They’re SDIC-insured up to S$75,000, pay more, and work as full digital bank accounts. If you haven’t already, the MariBank review covers how it stacks up.

How to start using moomoo Cash Plus

Who should use moomoo Cash Plus?
Use Cash Plus if: you already invest via moomoo and want idle brokerage cash to earn something between trades. If you’re dollar-cost averaging each month, Cash Plus earns on your monthly contribution while it waits to be deployed. If you hold USD in moomoo from selling US stocks, the USD Cash Plus option can work that cash too.
Skip Cash Plus if: you want the highest yield on your core savings — digital banks win. You want SDIC-guaranteed deposits — Cash Plus is not a bank deposit. You’re building an emergency fund — the lack of capital guarantee makes it unsuitable.
The ideal setup for most Singapore investors is a two-layer approach: keep your emergency fund and short-term savings in GXS Bank or MariBank for the higher guaranteed rate, and use Cash Plus only for idle cash inside your brokerage.
MariBank referral code 2DCT80WQ, GXS Bank code YONG477, and Trust Bank code HTWYQP95 all offer new user promotions. You can also use an Endowus referral code for managed cash smart products, or check the Singapore Savings Bonds guide for another risk-free option.
