The Federal Reserve unanimously voted on Wednesday to increase interest rates from 3.5%-3.75% to 3.75%-4%, marking the first rate hike in more than three years. Fed Chair Kevin Warsh stated the decision was "responsible" due to persistently high inflation, which has been above target for over five years. Major US banks including JP Morgan, KeyCorp, and BNY responded by raising their prime lending rates to 7% from 6.75%.
