The Federal Reserve's decision this week to lift the federal funds rate to a range of 3.75 to 4 percent marks another aggressive step in its inflation fight. But the move raises a fundamental question: is the central bank targeting the right enemy? Higher borrowing costs will not conjure up new oil supplies, unclog congested shipping lanes, or dismantle the tariffs that are inflating production expenses. What they will do is cool investment, dampen hiring, and put downward pressure on wage growth.
Before imposing those costs on the broader economy, policymakers should pause to consider whether they are fighting the inflation that actually exists. The core issue isn't just that prices are rising—it's why they are rising and whether interest rate hikes can do anything about the underlying cause.
Much of the recent price surge stems from supply-side disruptions. Geopolitical conflicts have rattled global energy markets, pushing up crude and gasoline prices, which ripple through nearly every sector. In August, gasoline prices jumped 3.9 percent and alone accounted for more than a third of the increase in the Consumer Price Index. And the pain doesn't stop at the pump: energy is an input into virtually everything we produce and consume, so higher fuel costs eventually show up even in core inflation measures that strip out energy directly.
But a one-time price level jump from a supply shock is not the same as a self-perpetuating inflationary spiral. If oil climbs from $70 to $100 a barrel and then stabilizes, the economy experiences a one-time adjustment in production and transportation costs. Once that adjustment is complete, the oil price increase alone does not keep generating inflation—unless oil continues to rise or the initial shock triggers a sustained round of wage and price increases.
The Fed is right to worry that a shock could metastasize. In the 1970s, oil shocks became embedded as wages and prices chased each other higher. But that history doesn't justify treating every energy spike as the opening act of a wage-price spiral. It forces a tougher question: how much economic activity should the Fed deliberately sacrifice to prevent a supply shock from spreading, and what evidence shows that such a tradeoff is already necessary?
Higher rates can restrain demand, but only indirectly. By making borrowing more expensive, they discourage consumption and investment, slow construction and business expansion, and ease pressure in the labor market. Softer demand gives firms less room to pass higher costs onto consumers. That's how monetary policy can keep a supply shock from broadening—by suppressing spending, investment, hiring, and wage growth elsewhere in the economy.
That mechanism matters because the Fed has a second mandate: maximum employment. The labor market remains reasonably healthy, but it's hardly overheating. Unemployment was 4.1 percent in August, and employment growth has slowed considerably from earlier in the recovery. If higher rates succeed in lowering inflation that is largely driven by energy and tariffs, they will do so by restraining the broader economy and putting jobs at risk.
If excessive demand were driving an accelerating inflationary process, tighter policy would be appropriate. But when energy disruptions and tariffs are raising costs, the Fed risks attacking the wrong problem. It cannot lower the price of oil, but it can make businesses less willing to invest, employers less willing to hire, and households less willing to finance major purchases such as homes, vehicles, and durable goods.
That doesn't mean the Fed should ignore inflation altogether. Policymakers should act if the shock begins feeding into accelerating wages, rising long-run inflation expectations, or broad price increases across sectors not directly exposed to higher energy or tariff costs. Those are the signs that a temporary price shock is becoming a self-reinforcing inflationary process.
Right now, the data do not show that pattern. Wage growth has slowed substantially from its pandemic peak, and unit labor costs—which measure labor compensation relative to productivity—rose just 1.2 percent in the second quarter of 2026. Long-run inflation expectations do not indicate that households expect today's inflation to persist indefinitely. Taken together, these indicators do not suggest that wages, labor costs, and expectations are beginning to reinforce one another in a self-sustaining inflationary cycle.
Without clearer evidence that wage and price pressures are broadening or that inflation expectations are becoming unanchored, the Fed should hold steady—even if markets have come to expect further tightening. The Fed should not tighten against the possibility that inflation will spread without evidence that it is actually spreading. Uncomfortable inflation numbers are not enough. Higher interest rates cannot reverse an external supply shock. They can only restrain the rest of the economy in an effort to contain it. Whether that tradeoff is justified depends on the data, not market expectations.
