It won't be enough.

In what would mark the most draconian and widespread ratings action since the financial crisis, on Friday Moody's warned it may cut the ratings on $22 billion of U.S. collateralized loan obligations - a fifth of all such bonds it grades - as a result of the collapse in cash flows due to the Covid-19 pandemic.

The ratings agency took action on 859 bonds from 358 CLOs that package leveraged loans into securities of varying degrees of risk and return. The step - which according to Bloomberg affects about 19% of Moody's-rated CLOs that purchase broadly syndicated loans - comes as the underlying debt gets downgraded at a record pace.
