Use 11.86% as context, not a promised rate
The Federal Reserve's 11.86% observation covers a specific 24-month commercial-bank series for May 2026. The Cost Index spans different terms and uses stated APR assumptions for controlled comparisons. A borrower should not substitute the public observation into every row or expect it from a marketplace partner. It is most useful as a dated reference point when evaluating how far an actual disclosure sits from a broad bank series.
