If you opt for BRS, can’t withdraw interest and TOP up
You can only opt for BRS in your retirement account if you pledged your property. After you have pledged, you will receive half of FRS in cash within a week. Any other balances left in your ordinary and special acc can also be withdrawn anytime via paynow. Withdrawals are done from the acc earning the highest interests rates, i.e. from SA acc before the OA.
