Generally, top ups made before 11 AM on a business day will be aggregated and a request to debit this amount from your SRS bank account will be placed the same day. If there are sufficient funds in your bank account, funds will be debited in 2-3 business days.
For eg., you have instructed Syfe to invest S$5,000 to Cash+ Flexi (SRS) and S$10,000 to Income+ Enhance (SRS) before 11AM on a Monday. Given both of these requests were submitted on the same day, after 11AM, a request will be sent to your SRS bank (DBS/POSB, OCBC, UOB) to debit S$15,000. If you have a balance of S$15,000 in your SRS bank account, this amount will be debited in the next 1-2 business days. If you only have say S$11,000 in your SRS bank account, considering the balance falls short of the aggregated amount of S$15,000, the debit request will fail. Syfe (from support@syfe.com email) will reach out to you informing you that you do not have sufficient funds in your bank account. View here for details on the next steps you can take at this point.
If you had placed the two investment requests; one before 11 AM and after 11 AM on a business day, the latter will only be processed the next business day.
In a scenario where you made one investment request before 11 AM and then a second one after 11 AM and a third one next business day after 11 AM, given that your first request is still being processed, your 2nd and 3rd requests will be aggregated and sent for debiting together. This ensures that your debit requests are sent in an optimised manner instead of sequentially so that your SRS funds can start investing and growing as soon as possible.
