Just go with cimb sg. It's the easiest one for Malaysians to open as it is all online. No need to visit SG. Wrong. The best way to send money to SG is using Sunway Money. Don't bother with MY banks -> banks unless you want to lose 2-3% upfront. However, I do recommend using Cimb SG -> Cimb MY as they have the best rate.
If you are just going to buy reits, be prepared to cough up cash every now and then for rights issue by reits. If you are not ready to cough up cash for rights issue, then you need to think is reits really for. It's inevitable.
Go with FSM SG. They deal with rights issue very well. Can even apply for access all from online. They are not useful for US stocks, unit trust. Avoid them totally for US stocks, unit trust.
Saxo all marketing and fees. Do not recommend them at all. Avoid.
PhillipCapital, OCBC Securities, UOB Kay Hian all fees only if you are using custodian account (quarterly platform fees)
DBS Vickers only useful if you want to open DBS account. Otherwise, not useful.
Standard Chartered high forex fees, they restrict you by preventing you from buying some US reits listed in SG. Hard for Malaysians to open. I will give it a skip.
Tiger, moomoo good for farming free shares and get instant 10% return by getting free shares. Keep in mind you can cash out the free shares after getting them and close account. No penalty. They are useful for US stocks if you don't want to use Interactive broker. I personally use Tiger for real time price for my US stocks as Interactive Broker does not have real time quotes and I am too cheap to pay for them. I do not know how they handle rights issue as I never use them for rights issue. I just use them for free real time US stock price.
Interactive broker, Highly recommended for US, HK, UK, AU, Canada, Europe stocks over anybody else. Super cheap commission and spot rate conversion (real time forex rate without any markup) and no platform or inactivity fess. Where can you find a broker which give you spot rates for converting your money and access to so many markets? Highly recommended.
Don't bother about CDP if you are buying reits. Why? If you don't have SG address and don't have access to a SG atm machine or access to a relationship manager, you cannot participate in rights issue. That's why I reocmmend FSM SG only for reits.
If it's too long, quick and short version to have
1. Cimb SG bank acocunt
2.Sunway money
3. Cimb Malaysia bank acccunt
4. Moomoo - for real time US stock price
5. FSM SG - for reits
6. Interactive broker - for other overseas holdings except sg reits.
Keep in mind I am writing this as someone who doesn't have priority/private banking in SG/SG address. Just your regular poor Malaysian. So if you have priority/private banking in SG/SG address, the above quick and dirty tutorial might not be suitable for you.
Wrong. Even as a nominee/custodian account, you get to attend the AGM. Only need to inform your brokerage that you want to attend. But like you said need extra work.
Wrong. You don't need a SG address. I registered with a Malaysian address.
Unless you are a whale or hold substantial amount say 5% of the reits holding, your voice doesn't matter.

Maybe rule changed. Anyway for S-REITs right subscription, you need a local SG address anyhow. Individually, you voice don't matter, but collectively, they matter, as seen in Sabana's case last year.
