Hey Shailesh
RBI regularly cancels NBFC licenses you can look them up on RBI site. It could be that they are cancelling more post Aug 18. I think they cancelled 40-50 NBFC in CY17, ~120 in CY16 and so on. Lets not start writing in Caps and calling it a bomb.
You can check out notification section for all cancelled year wise.
