How this number is built

The 30-year yield is the fitted spot curve read at 30 years — not a single bond's quote. The curve is refitted daily across every US High Yield (BB–D) Corporate bond with a usable price, so the tenor moves with the market rather than with whichever bond happened to trade. Outliers are flagged and excluded from the fit.
