Columbia Banking System, Inc. shares rise 1.47% after-hours amid uncertainty around Fed's future independence.

Columbia Banking System, Inc. rose 1.47% in after-hours trading. The increase in stock price may be attributed to the uncertainty around the Federal Reserve's future independence and the potential impact on inflation and interest rates. The upcoming interviews for the next Fed chair and the brief spike in the 30-year Treasury yield to 5% have added volatility to the U.S. markets, which could be influencing the stock's movement.
