Yes still. interest will be accrued from what I was made to understand. While you do not need to pay them in the next 6 months, you will still end up paying them, albeit in the future

This move is made to protect people's cashflow since many are not making much, if any income
As per my explanation above, that was actually a valid question. Just because you do not need to pay the principal and interest, doesn't mean that the bank would eat the loss. The bank would just consider this a deferred revenue for them which they will collect (likely with interest on top of it) in the future (6 months from April)
