SCB Singapore has a new i-banking cum brokerage system where you can enjoy NO MINIMUM brokerage fees. The catch is:

-No Contra. You have to have the cash in your Securities account before they allow you to key in your order. However, settlement for SGX is still done in T+3. Not a problem for those who are investing with money they have. Only a problem for those who contra beyond their means.
-Your shares will be kept in SCB Nominees. This subjects you to the counterparty risk of SCB failing; which I think is pretty remote. There are no custodian fees.
EDIT: I've been informed that even if SCB does fail; the legal and equitable titles are still ours; the shares will still belong to us should SCB Nominees fail.

-0.20% for SGX shares and 0.25% for NYSE, NASDAQ, Paris Bourse, Deutsche Boerse, London Stock Exchange, Swiss Stock ......
