It’s possible for those in repayment to only pay the interest amount each month. My daughter has two student loans and both state the amount of interest due and the amount of the payment being posted to principal. She’s at the beginning of the repayment, so if they did suspend interest payments her payments would drop to about $10 (from $40) per month for one and about $30 ($230) for the other, which would be a big help to her budget.
Of course, suspending them all together would be better!
