Over 9 million student loan borrowers past due after bills restarted, Fed estimates

Just now getting data?

my guess it takes at least 30 more days to be past due but often 90 and 180 days becomes particularly significant. Alls I can find in the article is:

"By the end of the off-ramp period, the New York Fed estimates that the volume of past-due federal student loans hit 15.6%, with more than $250 billion in delinquent debt."
