The Federal Reserve's 2026 Rate Hike: Why Did the Fed Raise the Federal Funds Rate After Three Years of Stability
1 viewsAbstract
Through this study, I seek to explore the reasons for the reversal in decision by the Federal Open Market Committee (FOMC) to increase the federal funds rate in September 2026, after five consecutive meetings without changing it and staying in this state for three years. In the context of expectations for continuation of easy monetary policy until early 2026, the decision to tighten the monetary policy represents a shift which has not yet been described clearly enough in public discourse. This research verifies whether the decision of the FOMC to break the holding trend can be justified by the energy price shock, labor market conditions, growth speed, and inflation persistence. Employing data provided by the Federal Reserve, the Bureau of Labor Statistics, and the Bureau, an event study of U.S. macroeconomic variables around FOMC meeting of September 16, 2026 was conducted . I considered five different indicators which are typically used in reaction functions for monetary policy (Taylor, 1993). They include headline and core inflation (CPI and PCE), the unemployment rate, the real GDP growth rate, and the price change of energy within a nine-month time frame. The results indicate that the reason for the change is mostly inflation pressure and not problems in the labor market. Even though the headline CPI grew up to 4.2% and then declined to 3.4% in August, the core PCE inflation grew up to 3.4% in May , its highest value since October 2023. The GDP growth rate went down from 2.1% to 1.5% between Q1 and Q2, while the unemployment rate stayed constant at 4.1%–4.4%. In summary , the Fed raised interest rates by 25 basis points through a 12-0 vote. The below are the results of this analysis: The Fed focused on maintaining price stability rather than promoting growth in this cycle since prolonged above-target inflation, together with the volatile prices of energy associated with the confrontation with Iran, were enough to warrant tightening while GDP was slowing. Nevertheless, there are some factors that contribute to uncertainty in terms of future rates, which include the difference between the market predictions and the actual Fed decision, as well as the uncertainty surrounding energy prices as a result of the Middle East.
