In a moratorium, your EMIs will be deferred. This means that during the moratorium period, no payment has to be made by the customer to MMFSL. Interest on the EMIs will keep accruing for the customer during this period and will be payable after the moratorium period with the deferred instalments.
In the 2nd round of moratorium, all instalments falling due in June, July and August will also be deferred by 3 months. So in total, moratorium covers 6 months period, i.e., from 1st March to 31st August, 2020.
