HSBC, Hong Kong's largest lender, and some smaller rivals are offering discounts on brokerage fees to entice customers amid the robust stock market. HSBC said from now to the end of next month, it would halve brokerage fees for all customers trading local stocks through its investment channels such as internet banking, except at branches. Existing customers can enjoy the discount only when the previous transaction value exceeded a pre-assigned target. The bank's current brokerage fee for transactions made through electronic channels is 0.25 per cent, or a minimum of HK$100 per transaction. Dah Sing Bank said customers who opened a securities account with the bank in the first quarter could enjoy brokerage fees of 0.1 per cent while Mevas Bank said no brokerage fee would be charged.
