    Yield Gap Widens Between Corporate and Muni Bond ETFs; Tax Strategy in Focus

    Question

    Yield Gap Widens Between Corporate and Muni Bond ETFs; Tax Strategy in Focus

    Direct answer

    With corporate bond yields at 4.90% and Munis at 3.20%, the 'tax-equivalent' yield for investors in the top federal bracket (37%) makes Munis the more attractive option on an after-tax basis. This dynamic is creating a floor for Muni bond prices even as Treasury yields remain volatile. The comparison between IGIB and MUB underscores the importance of tax-aware investing in the current high-rate environment. As the 10Y Treasury yield fluctuates, the spread between taxable and tax-exempt debt will be a key driver of fund flows within the iShares ecosystem.
