What is Longbridge Cash Plus?
Longbridge Cash Plus is a feature on the Longbridge platform that helps you make better use of your idle funds by automatically investing them in money market funds.
Money market funds typically invest in short-term instruments such as government and corporate bonds, commercial bills and fixed deposits, offering a way to earn potentially higher yields on spare cash while keeping it accessible.
Currently, Cash Plus invests your funds into the iFast SGD Enhanced Liquidity Fund A or the iFast USD Enhanced Liquidity Fund A.
Under the October LongbridgeAI promotion, eligible users can receive a 10% p.a. interest boost coupon for 90 days on up to S$3,600 invested through Cash Plus.
The bonus interest is settled every 30 days and credited to your account balance in Singapore dollars within approximately three working days.
Once the boost period ends, your returns will revert to the prevailing net yield of the selected fund.
Do note that money market funds are investment products and returns are not guaranteed.

Let’s break down how to qualify for the interest boost coupon.
Steps to earn 10% p.a. interest boost with Longbridge
Step 1: Sign up for a Longbridge account
Sign up for a Longbridge account via Beansprout.
To qualify for the LongbridgeAI Welcome Pack, you must be an eligible Singapore resident who, before 1 October 2026, had not previously sent a prompt to LongbridgeAI and had not deposited assets into your Longbridge account.
Step 2: Deposit funds into your Longbridge account
You can then deposit funds into your Longbridge account.
If you fund at least S$2,000, eligible new users who sign up through Beansprout can choose between:
- 3 months of Beansprout Pro access worth S$120, or
- S$80 FairPrice voucher
You will also need to submit the Beansprout claim form and select your preferred reward.
No trading is required for this Beansprout-exclusive reward.
If you maintain the S$2,000 net deposit for 30 days and complete three buy trades, you can also qualify for S$80 in NVIDIA fractional shares.
Step 3: Send a prompt to LongbridgeAI
Once your account is funded, you can open LongbridgeAI and send your first prompt.

Eligible users can receive 10% p.a. interest boost coupon for 90 days on up to S$3,600 with Longbridge Cash Plus, worth up to S$88.
The interest boost coupon is valid for 90 days once applied.
Do note that the interest applies up to only S$3,600 on Cash Plus, not your entire deposit.
Step 4: Enable Cash Plus and apply your coupon
Once your coupon is available, you can then enable Cash Plus where your idle money will be invested in money market funds.

You can activate Cash Plus by logging in to the Longbridge app, tapping “Market”, then “Funds” and then selecting the “Cash Plus” icon.

Once you've selected Cash Plus, you'll be brought to an Opt-In page to opt into the feature.

Once you opt in, eligible idle funds in your account will be automatically invested through Cash Plus.


The interest boost coupon will be credited to Me > My Coupons within 5 working days after you meet the criteria, and users will have 30 days to manually redeem their stock rewards.
Coupons are non-transferable, non-redeemable for cash, and cannot be reused.

How much can you earn with the cash boost coupon?
Let’s take a look at how much you could earn using the 10% p.a. interest boost coupon promotion.
First, you sign up for a Longbridge account through Beansprout.
Then, send your first prompt to LongbridgeAI to qualify for the LongbridgeAI Welcome Pack, which includes the 10% p.a. interest boost coupon for 90 days on up to S$3,600 in Cash Plus.
Within five working days, the 10% p.a. cash boost coupon will be credited to your account and can be found under Me > My Coupons in the app.
Once the coupon is credited, enable Cash Plus and apply it to your eligible balance.
If you keep the full S$2,000 in Cash Plus for 90 days, the bonus interest would work out to approximately:
S$2,000 × 10% × 90 ÷ 365 = ~S$49
That means you could earn about S$49 in bonus interest over 90 days, on top of the returns from the underlying Cash Plus fund.
If you instead apply the coupon to the maximum eligible balance of S$3,600, the bonus interest could reach about S$88 over 90 days.
| Amount in Cash Plus | 10% p.a. bonus interest over 90 days |
|---|---|
| S$1,000 | ~S$25 |
| S$2,000 | ~S$49 |
| S$3,000 | ~S$74 |
| S$3,600 | Up to 88* |
| *Longbridge states that the interest boost is worth up to S$88, with the bonus interest subject to the coupon's daily cap. | |
