I am interested to invest in the S&P 500 Index. Should I do it through Standard Chartered Bank/FSMOne and bear the risk of a custodian brokerage account or are there other better brokerages?

I would choose either Saxo or Interactive Brokers because they have the lowest fee.

Saxo min comm: USD4, with annual fee 0.12%

IB min comm: USD1, if total less than $100k has min fee $10/month which can be offset by commissions

Check out my video where i compare the rates and step by step guide how to use them:

I would DCA S&P500 ETF using FSMOne's ETF RSP.

Just have to bear in mind the dividend handling fee of US$2.5 min every distribution.
