I imagine a huge cash crunch is coming up soon as deferred payments come home to roost. We can’t continue kicking the can down the road forever. If people are over leveraged or insolvent we have to bear the pain eventually. It’s part of the credit cycle and it’s how savers get their foot in the door regarding asset ownership. Otherwise we will have basically embraced some absurd worst-of-both-worlds kind of socialism…
For mortgages I don't see why the deferrals are a problem as long as they are just tacked on to the end of the mortgage. It is going to be a major problem for renters.
Correct though that renters will be hurt more, though it will likely have less systemic effects.
