Fusion Bank Review: the CASH82P Rate Coupons, a 21% One-Week Deposit, Deposit Protection and Fees

Fusion Bank Limited is a virtual bank licensed under the Banking Ordinance. Formerly Infinium Limited, it received its banking licence from the HKMA on 9 May 2019, adopted its current name that July and opened fully in December 2020. The bank is a member of the Tencent Holdings group; its other shareholders include Industrial and Commercial Bank of China (Asia), Hong Kong Exchanges and Clearing and Hillhouse Capital.

Fusion Bank is a member of the Deposit Protection Scheme, which protects eligible deposits up to HK$800,000 per depositor. It has no branches: account opening, deposits, exchange and customer service all run through the app, and the customer service hotline is +852 2111 2688.

Fusion Bank offers HKD, RMB and USD deposits with no account maintenance fee; its flexible deposit plan starts at HK$100, and time deposits earn interest by tenor. For investing, funds start at HK$10 or US$1, some funds carry subscription fees as low as 0%, and money market fund redemptions can arrive as fast as the same day (T+0).

Foreign exchange covers HKD, RMB, USD, EUR, JPY and AUD with no handling fee, but only from Monday to Friday, 9am to 5pm, excluding public holidays. Local FPS transfers are free, and incoming cross-border remittances to a Fusion Bank account carry no receiving fee.

Download the Fusion Bank app through this site's link and enter invitation code CASH82P when opening the account; a successful opening brings three time-deposit rate coupons. The invitation page states maximum interest of HK$7,306 and US$1,000 and a top rate of 21% p.a.; that is the ceiling when all three coupons are used in full, not what every new customer should expect.

According to unofficial welcome information, the current round runs to 31 December 2026 and the three coupons are a one-week HKD time deposit (21% p.a. in total including the base rate, on HK$10,000 to HK$100,000), a three-month HKD time deposit and a three-month USD time deposit (4%). Fusion Bank has not published these details officially, so check each coupon's rate, principal cap, tenor and validity in the app after opening.

Disclosure: CASH82P is this site's own invitation code. If you open an account with it, Fusion Bank pays this site a referral reward; this does not reduce the coupons you receive.

Fusion Bank's published terms for its previous referral round (December 2024 to January 2025) state that coupons are issued within 7 working days of qualifying, with notice by app push and SMS; they appear under "Me > Offer Centre > Bank Coupons"; and the one-week coupon is valid for 7 calendar days from issue, after which it lapses and is not reissued.

The same terms provide that each coupon applies to one qualifying time deposit and counts as used once the deposit is placed; coupons cannot be transferred or exchanged for cash, nor combined with other account-opening promotions; and quotas are limited on a first-come, first-served basis. The current round's coupon terms are shown in the app, so confirm the validity period before arranging funds.

Fusion Bank calculates HKD time-deposit interest as simple interest on a 365-day year: principal × annual rate ÷ 365 × days. At 21% p.a. in total for seven days, HK$10,000 earns about HK$40.27, HK$50,000 about HK$201.37 and HK$100,000 about HK$402.74.

In other words, a week at 21% p.a. returns about 0.40% of the principal. The interest is a one-off: after maturity the money earns ordinary board rates, so 21% should not be used to judge a full year's return.

The one-week coupon yields at most about HK$403, so the remaining HK$6,900 or so of the HK$7,306 must come from the three-month HKD coupon. At a rate of around 2.8% p.a. for 90 days, that figure requires a deposit of about HK$1,000,000.

For the US$1,000, if the three-month USD coupon pays 4% p.a., Fusion Bank's 360-day basis for USD deposits means about US$100,000 deposited for three months. The maximum is therefore for well-funded customers; with HK$100,000, the realistic interest is about HK$403 plus whatever the three-month coupons pay on your own principal.

The promotion terms state that if a time deposit placed with a coupon is withdrawn early, the customer forfeits the bonus rate, earns only the bank's base rate and receives no replacement coupon. Early withdrawal itself is at the bank's discretion; the service charges set a penalty based on the amount withdrawn, the gap between a reference rate and the deposit rate and the days remaining, with a minimum of HK$200 (or the foreign-currency equivalent).

Among other fees, there is no account maintenance or minimum balance fee, and FPS and incoming cross-border remittances are free; each outgoing cross-border remittance costs HK$50 plus any intermediary bank charge. Foreign exchange carries no handling fee, and the rate quoted in the app applies.

Once the coupons are used, Fusion Bank runs deposit promotions for existing customers from time to time. Take the October 2026 "息多多" savings round: customers had to open a 息多多 savings account in the app between 1 and 31 October and move in at least HK$10,000 or US$1,000 of new funds (deposits made in the period minus the balance on 30 September), up to HK$10,000,000 or US$1,250,000.

HKD rates were 2.60% p.a. (to 30 November), 2.90% (December) and 3.10% (January 2027); USD rates were 3.00%, 3.20% and 5.00%. Interest is paid on the first day of each month, and withdrawals reduce the balance earning interest. A customer who opens an account in October has a zero balance on 30 September, so every deposit counts as new funds; quotas are limited and each round's conditions differ.

According to the app description, Hong Kong residents and visitors from mainland China can open an account online in the app with no appointment and no paper, usually in as little as about five minutes; requests for additional documents lengthen the review. The invitation code must be entered in the application: Fusion Bank credits a referral only to the code submitted with the account application, and it cannot be added after opening.

The steps: download the app through this site's link; enter CASH82P when opening the account; wait for the coupons after approval; check each one in the Offer Centre; open a time deposit of the matching tenor with suitable principal within the validity period; hold it to maturity. The referral programme applies only to people opening a Fusion Bank account for the first time.

As of 24 October 2026, the Fusion Bank app is rated 3.5 on the App Store in Hong Kong (456 ratings) and 3.3 on Google Play (about 1,600 ratings), with more than 100,000 downloads.

Positive reviews mostly cite competitive savings and time-deposit rates and a smooth opening process; negative reviews centre on account approval taking longer than the app indicates, document uploads accepted only in specific formats and slow replies after calling customer service.

Suits: Hong Kong residents with HK$10,000 to HK$100,000 of idle cash who can lock it away for a week and will check the coupon terms in the app; and well-funded savers who already plan a three-month HKD or USD time deposit.

Pass: anyone who may need the money at short notice; anyone treating 21% as a full-year return; anyone who needs branch service or credit card rewards; and existing Fusion Bank customers, who should look at the promotions for existing customers instead.
