How Does the Federal Reserve Control Inflation?
The Fed's interest rate hikes often worsen inflation by increasing government interest payments and business costs, while real inflation control requires fiscal policy addressing supply constraints.
Mainstream framing
Mainstream economics views the Federal Reserve as controlling inflation primarily through monetary policy tools, especially interest rate adjustments. When inflation rises, the Fed raises the federal funds rate to make borrowing more expensive, which reduces spending, investment, and economic activity, thereby cooling demand and bringing inflation down. The Fed also uses other tools like quantitative easing or tightening, forward guidance, and reserve requirements. This approach is based on the belief that the Fed can influence the money supply and credit conditions to manage aggregate demand and keep inflation near its 2% target.
MMT answer
MMT shows that the Federal Reserve's interest rate tool works differently than mainstream theory suggests, and often in ways that can be counterproductive for inflation control. As Warren Mosler and other MMT economists demonstrate, raising interest rates actually increases government spending through higher interest payments on Treasury securities, injecting more money into the economy rather than reducing it. This fiscal channel can be inflationary rather than disinflationary. Additionally, higher rates increase costs for businesses that must borrow, potentially leading to cost-push inflation as firms pass these higher costs onto consumers through higher prices.
MMT economists like Stephanie Kelton and Bill Mitchell emphasize that inflation is fundamentally about real resource constraints and bottlenecks, not excess money. The most effective tools for controlling inflation are fiscal policy measures that address supply-side constraints: strategic government investment in productive capacity, infrastructure, and supply chains; targeted price controls in essential sectors; and employment programs that enhance productive capacity rather than merely managing demand. The government's role as currency issuer means it can directly address inflation through strategic spending and resource mobilization, while the Fed's interest rate tool often works at cross-purposes to these goals.
