Strongly rising government yields in 2022 and, as a result, the worst year for bond returns since 1931, have fostered interest in long-term corporate bond returns within the context of rising interest rates. Unfortunately, most indices only go back to the 1970s and 1980s. We use yield-to-maturity indices published by the Federal Reserve for long-maturity corporate bonds operated by Moody’s to derive total return indices for AAA- and BBB-rated corporate bonds. The construction of this new dataset is intended to provide i) a novel toolset for evaluating long-term return characteristics of corporate bonds and, given the long-maturity nature of these indices, ii) a helpful proxy for benchmarking equity returns against.
