U.S. households have been taking on more debt for 17 straight quarters, leading to a total debt burden of $13.51 trillion at the end of the third quarter, according to the New York Fed.
That's 21% higher than the peak reached 10 years ago, in the third quarter of 2008 during the great financial crisis, and 1.6% higher than the debt level in this year's second quarter.
In addition to debt levels, delinquency rates also increased in the third quarter, from 4.5% in the second quarter to 4.7% in the third, reaching the highest rate in seven years.
Of the $638 billion in delinquent debt, 65% or $415 billion was at least 90 days overdue, aka "seriously delinquent," and student loan debt led in the deterioration.
While outstanding student loan debt increased 2.6% to $1.44 trillion as of September 30, 2018, 11.5% of student loans was 90+ days delinquent or in default. The flow of student debt into serious delinquency increased 9.1% but the rate could be twice as high because about half of those loans are in deferment, in forbearance or enjoying a grace period and thus temporarily removed from the repayment cycle, according to the New York Fed.
Mortgages continued to be the single greatest debt burden for American consumers, but mortgage debt increased at a slower pace than any other category of household because of historically tighter lending conditions, the New York Fed reported. The median credit score of new mortgages was 758, which suggests that more than half of all mortgages are going to individuals with high credit scores, according to the New York Fed.
