A further Fed interest rate cut holds the potential to stoke inflation by increasing the money supply and encouraging a spending and borrowing spree.....

 A further interest rate cut by the Federal Reserve (Fed) could fuel inflation and inflation expectations by encouraging a flood of spending and investment into an already strong economy. In contrast, rate cuts are conventionally used to stimulate growth when the economy is sluggish. The risk of stoking inflation is particularly high when a country's economic growth is already robust.

How interest rate cuts spur inflation

Encourages borrowing and spending: The Fed lowers the federal funds rate, which is the interest rate banks charge each other for overnight loans. This action causes other interest rates to fall throughout the economy, including mortgage rates, car loans, and credit card rates. This makes borrowing cheaper for both businesses and consumers, encouraging increased spending and investment.

Decreases savings incentive: Lower interest rates diminish the return on savings accounts and bonds. This disincentivizes saving and motivates individuals and businesses to spend or invest their money elsewhere in pursuit of higher returns, further increasing the money supply in the economy.

Boosts asset prices: As investors seek higher returns, they may shift money from low-yield bonds and savings into assets like stocks and real estate, inflating prices in those markets. This can also create a wealth effect, where individuals feel wealthier and increase their spending.

Weakens the currency: A cut in interest rates can weaken the value of the U.S. dollar relative to other currencies. A weaker dollar makes imports more expensive, which contributes to inflation. Conversely, it makes U.S. exports cheaper for foreign buyers.

Why inflation expectations matter

Changes in interest rates influence not just current inflation but also future expectations of inflation. These expectations can become a self-fulfilling prophecy.

Behavioral changes: If the public and businesses expect higher prices, they will change their behavior. Workers will demand higher wages to keep up with the rising cost of living, and companies may raise prices in anticipation of higher costs and demand. This cycle of rising wages and prices further fuels inflation.

Fed credibility: A key responsibility of the Fed is to maintain price stability, with a long-term inflation target of 2%. If the Fed is perceived as cutting rates too aggressively or at the wrong time, it could lose credibility in its commitment to fighting inflation. This can unmoor inflation expectations, making it more difficult to control prices in the future.

The Phillips Curve: This economic model describes an inverse relationship between unemployment and inflation. The logic is that as employment increases and approaches its "maximum" level, the labor market becomes tighter. This drives up wages and ultimately leads to higher inflation. Cutting rates to ensure maximum employment when the labor market is already strong risks pushing inflation beyond the Fed's target.

The Fed's balancing act

The Fed's actions are complicated by its "dual mandate" to promote both maximum employment and stable prices. This requires balancing the risks of a weakening job market against the risk of reigniting inflation.

In one scenario, the Fed may cut rates in response to a softening labor market, as J.P. Morgan projected in September 2025. However, if inflation remains elevated due to other factors (such as tariffs or supply-chain issues), further rate cuts could lead to a tough choice between supporting jobs and controlling inflation.

In another scenario, if the economy is already near or at full employment, as some recent reports suggest, further rate cuts are more likely to have an inflationary impact than to stimulate real growth.

Conclusion

A further Fed interest rate cut holds the potential to stoke inflation by increasing the money supply and encouraging a spending and borrowing spree. This effect is magnified when the economy is already robust. Critically, these rate cuts can also influence inflation expectations, a powerful driver of actual price increases. The challenge for the Fed lies in balancing its dual mandate of promoting maximum employment and stable prices, especially when these two goals pull policy in different directions. The risk is that misjudging the economy's strength could cause the Fed to lose credibility as a bulwark against inflation, further destabilizing prices.
