CITIBANK has expanded the marketing network of one of its mutual funds to include 12 local Citibank branches. This will enable retail customers to benefit from the planned spending in Asia on power stations, roads, telecommunications, airports, mass transit systems and other transport services. The fund, called Super Asia Infrastructure Fund, invests in infrastructure-related stocks throughout the Asia region and is targeted at investors who take a long-term view of investment in Asia. It is an open-ended fund listed in Luxembourg and authorised by the Securities and Futures Commission in Hongkong. The fund manager is Citibank Global Asset Management, the US bank's international asset management group, which manages a total fund portfolio of US$65 billion (HK$502 billion). Since its launch to institutional investors in December 1991, the fund has made solid gains, rising almost 16 per cent in 15 months. The fund invests in eight Asian markets: the newly industrialised economies of Hongkong, Taiwan, Korea and Singapore, and the emerging markets of Malaysia, Thailand, Indonesia and the Philippines. Mr Richard Owen, Citibank Global Asset Management's marketing officer in Hongkong, said: ''The fund is set to continue to benefit from infrastructure spending estimated to top US$500 billion in Asia outside Japan over the next six years.'' Most governments in Asia have focused on the importance of infrastructure spending in the 1990s to sustain economic growth and to avoid production and transportation bottlenecks in their economies. ''This spending should directly and indirectly benefit many companies in the region,'' Mr Owen said.
