Evidence from multiple data sources shows that U.S. consumer credit delinquencies/default‑like measures rose noticeably over 2023.

• The New York Fed’s Household Debt and Credit Q2 2023 report shows the share of credit card balances flowing into serious delinquency (90+ days) rose from 3.35% in Q2 2022 to 5.08% in Q2 2023, and auto loans from 1.81% to 2.41%. Overall serious-delinquency transition for all debts rose from 0.84% to 1.16%.(newyorkfed.org)
• The Q3 2023 report shows the same pattern: serious delinquency transitions increased across most debt types, with credit card serious delinquencies rising from 3.69% in Q3 2022 to 5.78% in Q3 2023, and auto from 2.02% to 2.53%.(newyorkfed.org) These are large percentage increases from already-depressed pandemic-era levels.
• Experian’s review of 2023 consumer credit reports that delinquency rates increased in 2023 across 30–59, 60–89, and 90+ day buckets, even while remaining below pre‑pandemic levels.(aol.com)
• By late 2023, financial press coverage noted that delinquency rates on credit card loans had reached their highest level since 2011, reflecting rising borrower distress as balances and interest costs climbed.(ft.com)
• An AP report on Q4 2023 similarly describes record credit‑card debt and climbing household delinquency rates, especially among younger and lower‑income borrowers.(apnews.com)

While definitions of “default” vs. “delinquency” vary, in consumer‑credit reporting these rising serious delinquencies and charge‑offs are exactly the phenomena the prediction referred to. Given the clear, broad-based, and historically large increases over 2023, the claim that U.S. consumer credit defaults would "rise meaningfully" during 2023 was borne out.
