The central bank decided to increase interest rates by 50 basis points, doubling what market analysts had widely anticipated. This decision comes as a response to persistent inflationary pressures despite prior interventions. The announcement triggered immediate reactions across various sectors of the stock market. Technology stocks, often sensitive to rate hikes due to their reliance on borrowing for growth, saw a significant downturn. The Nasdaq Composite fell by 2.5% just hours after the news broke out. Conversely, financial stocks experienced a surge, with the S&P 500 Financials sector gaining about 1.4%. Banks tend to benefit from higher interest rates as they can earn more from loan interest margins. Investor sentiment was mixed as they processed the implications of this aggressive rate hike.

While some view it as a necessary step to curb inflation, others worry about its potential to slow down economic growth and trigger a recession. The bond markets also reacted sharply, with yields on 10-year Treasuries climbing rapidly, reflecting concerns over tighter monetary conditions. In response to the Fed's announcement, market strategists are revising their forecasts for the U.S economy and stock market performance for the coming year.

Many believe that while this may dampen consumer spending and investment in the short term, it is crucial for restoring price stability and long-term economic health. As markets continue to digest this news, all eyes will be on upcoming economic data releases and Fed officials' speeches for further clues about future monetary policy directions.
