Regional bank stocks are trading lower as the yield on the 30-year Treasury bond climbed to its highest level since 2007. This surge in long-term interest rates is fueling concerns about higher borrowing costs for consumers and businesses, which could dampen loan demand and economic growth. The move in yields has prompted the U.S. Treasury to announce it will double the size of its debt buyback program to support liquidity in the bond market. Investors are also looking ahead to the release of the latest FOMC minutes for further clues on the Federal Reserve's stance on inflation and future rate policy.
