The October inflation data released by the Bureau of Labor Statistics offers a deceptive sense of relief. Yes, inflation rose 0.4% from September to October—slightly above expectations but presented as encouraging news. Yet buried in these numbers is an uncomfortable truth that policymakers and economists are dancing around: the main culprit driving current inflation is not monetary policy gone wild, but geopolitical crisis beyond the Federal Reserve's control. Higher energy costs driven by the Iran war have been the main factor behind increased inflation, and no amount of interest rate hiking will solve a problem rooted in Middle Eastern conflict.
Consider the energy picture. While gas prices cooled slightly in October, dropping from $4.41 to $4.22 a gallon, they remain more than $1 a gallon higher than a year ago. Diesel costs nearly $2.50 a gallon higher than last year. These aren't the results of loose monetary policy—they're the direct consequences of geopolitical instability. Fed Chair Kevin Warsh acknowledged on October 28 that the central bank's job is to ensure price changes in some sectors do not broaden across the economy, but this is precisely what the Iran war threatens to do. When energy prices surge, they ripple through every industry reliant on fuel and transportation.
The Fed's response has been to raise interest rates for the first time since 2023, with plans to hike again in December. The logic is sound in normal times: higher rates slow borrowing and cool inflation. But when inflation stems primarily from energy shocks rather than excess consumer demand, rate hikes become a blunt instrument that risks unnecessary economic pain. Growth in the labor market surpassed expectations in October with the unemployment rate hovering just above 4%, yet hiking rates could threaten these gains without meaningfully addressing energy-driven price increases.
Political consequences are already evident. The midterm election was largely seen as a rebuke of Republicans over high prices, with JD Vance and other party figures specifically pointing to frustration over increased gas prices. Consumer sentiment increased slightly at the end of October as gas prices eased, showing how directly energy costs influence public confidence. This political vulnerability reveals the real stakes: if geopolitical tensions escalate further and energy prices spike again, no amount of Fed messaging will prevent another electoral backlash.
The path forward requires honesty about what monetary policy can and cannot do. Kevin Warsh's October 28 statement about anchoring inflation expectations is admirable, but insufficient. Policymakers must acknowledge that solving current inflation requires addressing the Iran war's impact on global energy markets, not just adjusting interest rates. Until energy costs stabilize, the Fed risks raising rates too aggressively while failing to solve the actual problem driving inflation—leaving workers and businesses worse off without achieving price stability.
