Credit Card Balances Turning Seriously Delinquent, Ages 18–29 (NY Fed)

## What this measures

The percent of credit card balances of borrowers aged 18 to 29 that transitioned into 90 or more days delinquent, as a four-quarter moving sum.

## Why it matters

Young borrowers have thinner savings and credit files, so card stress tends to show up in their balances first and hardest.

## How to read it

Higher is worse. Compare with the all-ages rate (credit.hhdc.flow_serious_cc) to see whether stress is concentrated among the young.

## What it does not say

A four-quarter moving sum, so it smooths and lags quarterly changes. Age comes from birth year on the credit file.
