Thanks, you're using CIMB SG or MBB SG?

I think you're confused. He didn't transfer a bank. He transferred straight to IBKR!

You opened IBKR first without going through TSG, right? If it says different entities, then you need to re-do everything, ie go through TSG website to open an account with IBKR. They will redirect you to an IBKR website.

If it says different entities, it means you can't link your ibkr to TSG. You've opened a different IBKR, not the one approved by TSG. 
I tried last Friday, will report my findings later this week.
Use transferwise.
It's nice that you called the hotline to confirm .... 

but I just want to say that, most if not all of us here are not working in a bank. What we posted here is what we have experienced, regardless of what a website, a customer service officer or a bank officer may say. Most of the time, when it comes to very specific questions that are not written black and white on the internet, I find internet users are more reliable because they have been through the process, whereas the customer support would usually be MCC mong cha cha.

Sometimes you see things like, "You're supposed to do/have A, B, C, ......" and even so, ppl went through without doing or having A, B, C.
Another example, IBKR doesn't encourage us to transfer money using fintech and yet we still do it. One guy even did it with BigPay. 

so you can understand sometimes ppl feel tired explaining. Sometimes I said something, then someone said, not written on the website. Then I've to play the sure-win card, "I talked to ibkr and they told me so!"  It's ok once in a while but sometimes I feel like giving up. Let them explore themselves.

Anyway, if you have other questions, feel free to post them here. We'll reply based on our experience.
1) Means your documents need to be certified by a notary public, but I don't remember going through this step.

2) I don't understand your question, what pump in fund???
Must deposit to activate the acc la.... can't open it and let it have zero balance for 10 years right?
The base currency doesn't matter. You can deposit in any international currencies.

Thank you ramjade! Looks like with a heavy heart, I might just have to open the CIMB SG Account.

I did see moosset is experimenting on withdrawing straight from IBKR to MY bank via TransferWise. maybe i'll wait and see, haha.

No need open SG bank account. Don't waste your money. Just donate free money to banks. Of course banks will be telling you thank you but without any show of appreciation   

Anyway my money overseas is one way ticket. I won't bring money back to malaysia.

Hmm... eventually if you retire you also don't bring the money back to Malaysia? ie unless you plan to retire in other countries.

On a side note, anyone knows what to do with spare cash in IB to maximize the value? Yet flexible enough to withdraw and buy shares. Currently I am all pure cash sitting in my IB account...

oh wow, i'm interested!

what's your game plan? planning to move overseas in the future?

Nope because if I bring back RM it will depreciate. Just use my EPF.

Forget about using IB to get a extra money. The most you can do is buy a money market fund.

For me I keep in CIMB fastsaver.

Buying money market fund... do you have any to recommend? If got charges, then this option might not be good since I plan to use the cash to buy when there's a good opportunity.

Hmm... putting in CIMB SG account means very little interest rate. I guess it really depends if your living lifestyle and retirement planning. For me I just plan to move everything back to Malaysia.

Can we withdraw from IBKR to TW then to MY bank?

I managed to withdraw from IBKR to TW Borderless account!! 

I managed to withdraw from IBKR to TW Borderless account!! 

TW borderless account does not have interesr

IBKR u withdraw USD and transfer to TW in USD?

beggars can't be choosers. 
I withdrew EUR from IBKR to TW Borderless acc (EUR).

why not SGD? considering IBKR forex rate so good i would have transfered in SGD to TW as SGD/MYR still can get competitive rates.

Because my currency was in EUR and I wasn't bringing money back to M'sia.
IBKR (EUR) >>> TW (EUR)

You can of course choose SGD as a transit to bring your money back.
IBKR (EUR) >>> TW (SGD) >>> Malaysian bank (MYR)

Anyway, the whole point was to check if TW can be a transit or a storage for our money from IBKR and it works!

considering the spread, thank you for your sacrifice.
