What Is Longbridge Cash Plus?
Longbridge Cash Plus is a cash management feature built into the Longbridge brokerage app. Instead of letting your uninvested cash sit idle earning nothing, Cash Plus automatically sweeps it into money market funds (MMFs) that generate daily returns.
For SGD balances, Cash Plus invests in the iFAST SGD Enhanced Liquidity Fund A. For USD balances, it uses the iFAST USD Enhanced Liquidity Fund A. Both funds invest in high-quality, short-term instruments — government bills, bank deposits, corporate bonds, and commercial bills maturing within 397 days.
The feature launched as part of Longbridge’s push to become a full-service investing platform in Singapore, alongside commission-free trading on SG, US, and HK stocks. Cash Plus competes directly with similar features from Moomoo Cash Plus and Tiger Vault — all of which aim to keep your idle brokerage cash productive between trades.
Cash Plus is available to all Longbridge Singapore account holders. There is no separate application — you simply opt in through the app.
Current Interest Rate (September 2026)
The base yield on Longbridge Cash Plus for SGD fluctuates with market conditions. As at September 2026, the 7-day annualised yield for the iFAST SGD Enhanced Liquidity Fund stands at approximately 1.3% p.a. This rate is not fixed — it moves with underlying money market rates, which have been declining from their 2023–2024 highs as central banks cut interest rates.
For USD balances, the yield is higher at approximately 3.9% p.a., reflecting the higher US federal funds rate.
| Currency | Underlying Fund | Approximate Yield (Sep 2026) |
|---|---|---|
| SGD | iFAST SGD Enhanced Liquidity Fund A | ~1.3% p.a. |
| USD | iFAST USD Enhanced Liquidity Fund A | ~3.9% p.a. |

Promotional Interest Boosts
Longbridge regularly runs promotional campaigns that add bonus interest on top of the base Cash Plus yield. As at September 2026, the current promotion offers:
- 10% p.a. interest boost for 100 days on up to S$3,000 in Cash Plus — part of the LongbridgeAI Welcome Pack for eligible new users (worth up to ~S$82 in bonus interest)
- Previous promotions have included 5% p.a. for 365 days on the first S$4,000
These promotional boosts are paid in cash on top of the fund’s returns. Once the boost period expires, your returns revert to the prevailing fund yield. To check the latest promotions, visit the Longbridge promotion Singapore page.
How Cash Plus Works
Cash Plus operates on a simple auto-sweep mechanism:
1. You opt in once. Open the Longbridge app, go to Market → Wealth → Cash Plus, and tap “Opt-in”. That’s the only manual step.
2. Auto-sweep kicks in. Any uninvested SGD or USD sitting in your Longbridge account is automatically routed into the corresponding money market fund. The minimum sweep amount is just SGD 1 or USD 1.
3. Daily returns accrue. The fund generates returns daily based on its holdings of short-term instruments. You’ll see your Cash Plus balance grow incrementally each day in the app.
4. Instant redemption for trading. When you place a buy order for stocks, options, or other securities, Longbridge automatically redeems the required amount from Cash Plus — no manual action needed. There’s no delay or penalty.
5. Withdrawals take 3 business days. To withdraw cash to your bank account, you’ll need to turn off auto-sweep first, then initiate a withdrawal. Funds marked for withdrawal are not included in your buying power during this period.

Key Takeaway
If you’re already a Longbridge user, Cash Plus is a no-brainer — your idle cash earns something rather than nothing, with zero friction. But if you’re choosing a platform purely for the best cash yield, Tiger Vault’s higher base rate (~3.7% p.a.) currently leads the pack among brokerage cash features. For guaranteed, SDIC-insured savings with no investment risk, digital banks like GXS and MariBank remain the safer choice — albeit at lower rates.

Key Features
Here’s what makes Longbridge Cash Plus worth considering for Singapore investors:
Auto-Sweep From SGD 1: Once activated, any uninvested cash above SGD 1 (or USD 1) is automatically swept into the money market fund. No manual subscription needed.
Zero Fees: Longbridge charges $0 subscription fees, $0 redemption fees, and $0 platform fees for Cash Plus. The only costs are the fund’s internal management fees, which are already factored into the NAV — what you see in your account is yours to keep.
Instant Trade Access: Your Cash Plus balance counts as buying power. When you place a trade, the app redeems the necessary amount seamlessly behind the scenes. There’s no need to manually sell fund units before buying a stock.
Daily Returns: Interest accrues daily and is reflected in your Cash Plus balance. Returns are based on the underlying fund’s performance investing in short-term debt instruments.
Dual Currency Support: Cash Plus works for both SGD and USD balances, each routed to the respective iFAST Enhanced Liquidity Fund.
Promotional Boosts: Longbridge frequently offers interest boost coupons — e.g. 10% p.a. for 100 days — that stack on top of the base fund yield. These are typically tied to new user sign-ups or deposit milestones. Check the latest deals on our Longbridge promotion Singapore guide.
Is It Safe? (SDIC, Money Market Funds & Risks)
This is the most important section if you’re considering parking significant cash in Longbridge Cash Plus.
Cash Plus is NOT a bank deposit. It is an investment product — specifically, a money market fund managed by iFAST. This means:
- Not SDIC-insured: Unlike savings accounts at banks like GXS, MariBank, Trust Bank, or DBS, your Cash Plus balance is not protected by the Singapore Deposit Insurance Corporation (SDIC). If the fund suffers losses, your capital is at risk.
- Not capital guaranteed: While money market funds are managed with a conservative mandate and rarely lose money, there is no guarantee that you’ll get back 100% of your principal. In practice, well-managed MMFs in Singapore have an extremely low risk of capital loss, but it is theoretically possible.
- Returns fluctuate: The yield is not fixed. It moves with prevailing money market rates and the fund manager’s investment decisions.
However, the risk is relatively low. Money market funds invest in the highest-quality short-term instruments — T-bills, bank deposits, investment-grade commercial paper. The iFAST SGD Enhanced Liquidity Fund is regulated by MAS and managed under strict investment guidelines.
Longbridge itself is MAS-regulated. Longbridge Securities (Singapore) Pte. Ltd. holds a Capital Markets Services (CMS) licence from the Monetary Authority of Singapore. All client funds are held in segregated custodian accounts with major local banks, kept entirely separate from Longbridge’s operating funds.
For investors who want SDIC protection on their emergency funds, a digital bank savings account — such as GXS Bank or MariBank — is the more appropriate choice. Cash Plus is best used for funds you’ve already allocated to investing and want to keep earning while between trades.

For SDIC-insured savings, consider digital banks like GXS or MariBank instead.
How does Longbridge Cash Plus compare to Moomoo Cash Plus?
Both Longbridge Cash Plus and Moomoo Cash Plus work similarly — they sweep idle cash into money market funds with no lock-up and instant trade access. As at September 2026, both offer comparable base SGD yields of approximately 1.3% p.a. The main differences are in their promotional offers and underlying fund choices (Longbridge uses iFAST funds while Moomoo uses the Fullerton SGD Cash Fund). Both charge $0 platform fees and are not SDIC-insured.
Are there any fees for Longbridge Cash Plus?
No. Longbridge charges $0 subscription fees, $0 redemption fees, and $0 platform fees for Cash Plus. The only costs are the fund’s internal management fees (charged by iFAST as the fund manager), which are already factored into the daily NAV.

Can I withdraw money from Longbridge Cash Plus to my bank account?
Yes. You’ll need to turn off the auto-sweep feature first, then initiate a withdrawal within the Longbridge app. The cash will be transferred to your linked bank account within 3 business days.

Is Longbridge Cash Plus worth it in 2026?
If you’re already a Longbridge user, Cash Plus is worth activating — your idle cash earns returns instead of sitting at 0%, with no fees or lock-up. However, the base SGD yield of ~1.3% p.a. is modest compared to Tiger Vault (~3.7%) or even some digital bank accounts. Cash Plus is best suited as a holding place for funds you’ve allocated to investing, not as a primary savings vehicle. Take advantage of promotional interest boosts when available for the best returns.
