South Dakota Banks: Highest Credit Card Delinquency

Definition and formula

The credit card noncurrent rate is the share of a bank's credit card loans that are 90 or more days past due and still accruing, or on nonaccrual. Card issuers usually keep accruing interest until they charge a balance off, so most of the rate is the 90 or more days past due bucket.

Credit card noncurrent rate = (Credit card loans 90+ days past due and still accruing + Credit card loans on nonaccrual) / Credit card loans

Which banks are ranked

This list ranks the 8 banks headquartered in South Dakota that meet every rule below, using each bank's latest FFIEC call report (data as of September 30, 2026).

• Banks with at least $100M in total assets, so a ratio on a very small balance sheet cannot lead the list.
• Banks with at least $25M in credit card loans, so a rate on a few loans cannot lead the list.
• Lending institutions only: charters with loans under 5% of assets, mostly trust and custody banks, are not ranked.
• Charters the regulator has closed, merged or converted are excluded.
• Each bank charter ranks on its own; holding companies are not combined.

What moves the credit card noncurrent rate

Card delinquency rises when household budgets tighten: higher prices, job losses and thinner savings all push it up. Issuers that lend to borrowers with lower credit scores, including store card and partner programs, run structurally higher rates. A card balance is charged off once it is 180 days past due, so a bank that writes off sooner or sells late-stage accounts shows a lower rate for the same borrowers.
