Hang Seng Investment Management tomorrow launches a US dollar forex fund for people with a minimum investment of HK$20,000. The bank said in a statement yesterday that in view of the high demand for foreign currency investments from retail investors, the fund would allow investors to participate with as little as HK$1,500 per month through the Hang Seng regular investment plan. 'In Hong Kong, there has been a good customer demand for foreign currency investment which is evident from the relatively high proportion of foreign currency deposit,' Hang Seng Bank managing director Mok Wai-kin said. The latest fund brings to 14 the number of sub-funds under the Hang Seng Investment Series - which is worth HK$3.34 billion. The fund capitalises on the movement of foreign exchange rates and invests in assets denominated in various currencies to gain long-term capital appreciation in US dollar terms. Within a particular currency, investments may be held in a combination of bank deposits, certificates of deposits, floating rate notes, short-term money market instruments, bonds of fixed rate securities of varying maturities as well as derivatives. The investment company's general manager, Cheung Ka-ming, said the fund provided a potential return which was higher than regular bank deposits over the medium to long term.
