The Federal Reserve (Fed) is facing mounting pressure to raise interest rates next week, as several unfavorable factors contribute to ongoing inflation concerns. The central bank has maintained its federal funds rate in the range of 3.5% to 3.75% since December 2025, but investors are bracing for a potential hike in response to persistent price pressures stemming from the ongoing Middle East conflict.

According to the CME Group's FedWatch tool, the likelihood of a rate increase has surged to 70% following reports indicating that the Producer Price Index (PPI) rose by 0.4% in August, coinciding with a spike in West Texas Intermediate (WTI) crude oil prices exceeding $100 per barrel. Additionally, the probability of another rate hike in December has climbed to nearly 60%, as inflation trends appear stubbornly high, prompting the central bank to consider action.

Jeffrey Roach, Chief Economist at LPL Financial, noted, "As the conflict with Iran extends longer than anticipated, inflationary pressures are becoming more entrenched, leading investors to seek a strong catalyst to shift the inflation narrative. Given this trajectory, the likelihood of a rate increase next week is very high." The PPI's annual increase now stands at 5.4%.

Simultaneously, escalating tensions in the Middle East have raised concerns and pushed U.S. crude oil prices up by 4%, surpassing the $100 per barrel mark. The European Central Bank (ECB) recently raised rates by 25 basis points, adjusting its inflation forecast due to fears that the conflict with Iran could have broader economic implications and long-term effects on consumer prices.

David Russell, Global Market Strategist at TradeStation, commented, "Pressure will continue to mount as crude oil and refined product prices keep rising since the data for August was collected. The ongoing surge in oil prices, combined with low unemployment claims, will compel the Fed to raise rates next week."

Before the Fed's meeting next week, policymakers will have access to final inflation data, with the U.S. Bureau of Labor Statistics (BLS) set to release the Consumer Price Index (CPI). Dow Jones' consensus forecast suggests that the overall CPI will increase by 3.4% in August year-over-year, while the core CPI (excluding food and energy) is projected to rise by 2.4%.

However, the Fed focuses on the Personal Consumption Expenditures (PCE) index published by the U.S. Department of Commerce. This index indicates that core PCE rose by 3.3% in July, while overall PCE increased by 3.7%. Fed Chair Kevin Warsh recently reiterated that PCE is the central bank's official inflation measure.

Stephen Juneau, an economist at Bank of America Securities, remarked, "This CPI report is unlikely to change the perception that the inflation containment process is limited and will likely provide a solid basis for the Fed to decide on a rate hike at the September meeting."

Previously, Fed Chair Warsh had expressed more caution regarding future moves. However, during last month's annual Fed conference in Jackson Hole, he stated that the Fed would have "more work to do" if inflation does not decrease to the central bank's target of 2% at a "sufficiently fast pace."

Meanwhile, Bank of America has issued one of the most hawkish forecasts for the Fed on Wall Street, expecting the central bank to raise rates three more times in upcoming meetings. This forecast contrasts with current market expectations reflected in futures prices, but recent developments indicate that the Fed may pursue a more aggressive stance in its battle against inflation.

Peter Boockvar, Chief Investment Officer at OnePoint BFG Wealth Partners, suggested that even if the CPI remains low, it may simply reflect businesses' increasing difficulty in passing higher costs onto consumers. "Those who only look at consumer prices to gauge inflation and predict interest rates will miss the bigger picture; recent PPI data shows that inflation issues persist throughout the supply chain," Boockvar stated.
