Regional bank stocks, as measured by the KRE ETF, fell in morning trade as a broader market sell-off was fueled by a significant rise in U.S. Treasury yields. The 10-year Treasury yield climbed to its highest level since 2002, creating a challenging environment for interest-rate-sensitive sectors like regional banks. The market is also positioned cautiously ahead of the release of the Federal Reserve's September meeting minutes later today, which could provide further clues on the future path of interest rates.
