Corporate bond index
BBB corporate bonds
An index effective yield: the average yield across every bond in the index, weighted by market value. No single bond pays this.
A published rate series is a number somebody else measures and releases on a schedule: an official calculation, a survey of lenders, or an average across many institutions. It is not a price you can trade at, and it is not an offer: no bank, broker or issuer has to give anyone the figure on this page. The date beside the value is the day the publisher observed it, not today, and the number stays exactly as released until the next observation appears. Read it as a reference point for what this kind of borrowing or lending cost on that date, and nothing more.
History
260 observations from Oct 14, 2025 to Oct 08, 2026. Range over the period: 4.86% to 6.23%. Change across the window: +1.21% points.
What this number is
The lowest investment-grade rung, where most corporate income sits.
The value shown is the most recent observation published for series BAMLC0A4CBBBEY by FRED, dated Oct 08, 2026. We store what the publisher released and never interpolate a value forward to today: if a series has not been updated, its date says so and the page flags it rather than implying the number is live.
See it in context on the Bonds page, where it sits beside the rates it should be compared with.

Recent observations
Straight from the publisher's series, newest first.
Each row is one observation, exactly as it was published. How often rows appear is the publisher's own schedule (daily, weekly, monthly or quarterly), so a short list is not a rate that stopped moving, and a gap is usually a holiday or a series that simply reports less often. Nothing is filled in between the rows.
