About AA US Corporate Bond Index (Total Return)

What it measures

The ICE BofA AA US Corporate Index Total Return series (FRED series BAMLCC0A2AATRIV) tracks the cumulative total return, price change plus reinvested coupons, of US dollar investment-grade corporate bonds rated AA. ICE Data Indices calculates the index daily, and FRED reports the total return index value rather than a yield or spread.

Why it matters

AA-rated corporates sit near the top of the credit spectrum, so this index shows how the safest private-sector bonds perform through rate and credit cycles. Portfolio managers use it as a benchmark for high-grade credit allocations and compare it against Treasury and lower-rated indexes to isolate how much return comes from duration versus credit risk.

How to read it

The index level only has meaning relative to its own history: upward drift reflects coupon accrual, while drawdowns indicate rising yields or widening spreads. Because AA issuers rarely default, returns are driven mainly by interest-rate moves, making the index behave much like duration-matched Treasuries. Compare it with the BBB counterpart to see how credit quality differentiated performance in a given period.
