What Makes the Fed Raise or Cut Rates - and What Follows

What Pushes the FOMC Toward a Rate Hike

• Inflation running above target: Persistent price increases above the committee's two percent objective are the most direct case for tightening.
• A labor market beyond full employment: Very low unemployment alongside rapid wage growth suggests demand is outrunning the economy's capacity to supply.
• Rising inflation expectations: Survey and market-based measures that drift upward are treated as a warning that price increases are becoming self-perpetuating.
• Demand growing faster than potential output: Strong consumer spending, business investment, and credit growth all argue for restraint.
• Financial conditions that are too easy: Rapid credit expansion and unusually loose lending standards can prompt tightening even when measured inflation is contained.

What Pushes the FOMC Toward a Rate Cut

• Inflation running below target: Persistently weak price growth risks the deflationary dynamics that proved so costly in the 1930s and in Japan after the 1990s.
• Rising unemployment: A deteriorating labor market is the clearest signal that the maximum employment half of the dual mandate is at risk.
• Contracting output or falling investment: Weak or negative growth in real activity argues for easier policy.
• Financial stress: Bank failures, frozen credit markets, or a sharp widening of credit spreads have historically triggered rapid and occasionally inter-meeting cuts.
• Adverse external shocks: A slump among major trading partners or a global disruption can weaken domestic demand enough to justify easing.

What a Rate Increase Does

• Short-term borrowing costs rise first: Bank funding rates, credit card rates, and other rates tied to short maturities move quickly.
• Interest-sensitive spending falls: Housing, vehicles, and business capital projects are the components of demand that respond most.
• Bond prices fall as yields rise: Existing fixed-coupon bonds lose market value when newly issued bonds carry higher yields.
• The currency tends to strengthen: Higher domestic returns attract capital inflows, which raises demand for the currency and weighs on export competitiveness.
• Inflation pressure eases with a lag: Weaker aggregate demand slows price increases, but typically only after several quarters.

What a Rate Cut Does

• Credit becomes cheaper: Lower borrowing costs make mortgages, car loans, and business financing more affordable.
• Interest-sensitive demand recovers: Home building and durable goods purchases are usually the first components of spending to turn.
• Asset prices tend to rise: A lower discount rate raises the present value of future cash flows, and bond prices rise as yields fall.
• Saving becomes less rewarding: Deposit and money market returns fall, which is one of the standard distributional criticisms of prolonged easing.
• The currency tends to weaken: Lower relative returns can reduce capital inflows, which supports exports and raises the price of imports.

Why the Effects Arrive With a Lag

Monetary policy famously works with what Milton Friedman called long and variable lags. A change in the federal funds target moves overnight bank funding costs immediately, but it reaches household and business spending only as loans reprice, projects are reconsidered, and contracts come up for renewal — and it reaches consumer prices only after that. Conventional estimates place the delay between a rate change and its peak effect on inflation at roughly one to two years, with wide uncertainty around that figure. This is why the FOMC describes itself as acting on a forecast rather than on current data: by the time inflation is unmistakably too high in the published numbers, a policy change made today will not bite for several quarters. It is also why both over-tightening and over-easing are easy mistakes to make.
