Mainstream Fund Services in Hong Kong

It seems every day there is another report on the growth prospects of Hong Kong for both traditional and alternative investment managers.

We see enormous opportunities for fund flows, from the opening up of the Chinese market and RMB internationalisation, to the Asia Region Funds Passport, Association of Southeast Asian Nations (ASEAN) Collective Investment Scheme (CIS) and Hong Kong-Mainland China mutual fund recognition initiatives.

Taking advantage of these opportunities requires expertise and investment. That is why we continue to see fund managers outsource non-core processes to specialist fund administrators.

Mainstream Fund Services, part of Mainstream, specialises in fund services in Hong Kong and mainland China. We are a boutique administrator known for our end-to-end fund service where you choose the start and end points.

We offer a full service back office including middle office, transfer agency, fund administration and fund accounting to both local domicile and international funds.

Mainstream Fund Services opened an office in Hong Kong in 2013 and acquired middle-office service provider HFO’s operations in 2014 to expand our presence in the city.

We are known for our entrepreneurial, flexible and cost effective approach and we bring this same passion to our clients in Hong Kong and mainland China.

We are here to support local fund managers with our regional knowledge and economies of scale. We can also assist offshore firms wanting to enter Asia’s main fund management and alternative investment hub.

We predict Hong Kong will attract record investment inflows over the coming years, given the number of cross-border initiatives underway in Asia. These increased investment flows will be a catalyst for automation. With our expertise and leading fund technology, your fund business can capitalise on these opportunities.
