Federal Reserve Governor Michelle Bowman indicated Tuesday she is prepared to support an interest rate increase if U.S. inflation fails to cool further, adding to a growing chorus of hawkish sentiment from central bank officials. With rising Treasury yields and prior hawkish remarks from Fed Chair Kevin Warsh amplifying expectations, markets have now priced in a roughly 66% probability of a rate hike at the Fed's September meeting, according to the CME FedWatch tool.

Speaking at a banking forum in Washington, Bowman expressed concerns that broader price pressures could be building gradually. Inflation has now remained above the Fed's 2% target for nearly five and a half years, keeping policymakers alert to the persistence of high prices. In prepared remarks, she stated that if incoming data trends reinforce confidence that inflation is moving back down toward 2%, the committee could afford to take more time to assess the current policy stance. However, she added that if inflation does not appear to be easing sufficiently, officials should act decisively and raise interest rates.

Bowman's comments signal she is not opposed to resuming monetary tightening given the prolonged failure of inflation to return to target. As a Fed governor, she holds a permanent voting seat on the Federal Open Market Committee (FOMC), making her policy stance a key marker for markets assessing the future path of rates. She previously supported the Fed's decision to hold the federal funds rate at 3.50%-3.75% in July. But with September approaching, hawkish signals within the Fed are clearly increasing.

Bowman reiterated that if economic data convincingly show inflation falling toward the 2% goal, the Fed could continue to wait and observe. But if the cooling proves insufficient, a decisive hike would be warranted. This suggests upcoming inflation prints could be the critical determinant of whether the Fed reengages its tightening cycle.

Despite her hawkish lean, Bowman offered a relatively positive assessment of the broader U.S. economy, noting consumer spending has remained resilient so far. Still, she stressed that high price pressures are a greater worry than growth itself. "Inflation is still too high, and it has been for over five years," she said. Latest data show overall prices rose 3.7% year-over-year, while core inflation, excluding food and energy, rose 3.3%—both well above the Fed's long-term target.

The Fed will receive more critical price data before its next policy meeting. Both the Consumer Price Index (CPI) and Producer Price Index (PPI) are scheduled for release next week, offering key evidence on whether inflation is genuinely reaccelerating or beginning to cool again. If price pressures prove stubborn, Bowman's suggestion of a decisive rate increase could gain more traction within the FOMC. Conversely, a notable easing could give the Fed room to hold steady and monitor economic conditions.

Bowman's remarks come as markets had already significantly raised expectations for a September hike. Warsh's recent speech was widely interpreted as favoring an even tighter monetary stance, prompting investors to seriously consider the possibility of a move at the next meeting in two weeks. According to the CME FedWatch tool, market pricing for a September hike now stands at approximately 66%, a notable shift from previous assumptions about the policy path. With several policymakers increasingly focused on inflation running above target, uncertainty surrounding the September gathering has clearly elevated.

External factors are also complicating the Fed's inflation fight. Renewed worries over potential escalation in the Middle East drove Treasury yields sharply higher on Tuesday, with the benchmark 10-year yield rising to levels not seen since mid-January 2025. Geopolitical tensions could feed into U.S. inflation through energy prices. If supply disruptions push oil prices persistently higher, the Fed could face a more complex policy environment—balancing a resilient economy and consumer spending against inflation that remains well above target and rising external price pressures. In this environment, market expectations for a resumption of Fed rate hikes are accelerating quickly.
