Bro,... a quicker way would be to open a CIMB Msia acct and link this acct to fast saver CIMB SG.

You can convert back immediately AND ACCESS YOUR FUNDS IMMEDIATELY BY GOING TO A CIMB MSIA ATM.

Rates are good too,... NO need to develop headache over porting over to Instarem first.

Have you read this thread?

Yes bro,... you can. Just follow the steps in the CIMB SG website. If you have a CIMB Msia account, you can use this acct to transfer in the SGD1000 to activate your acct...

After you bank-in the SGD1k, you need to wait one day for the acct to be activated.

Sometimes, CIMB SG may ask you to send them again some identification documents because they may have 'lost ' the earlier documents you emailed to them. Just follow their requests.

No issue, bro,...
