Fed Rate Hikes: Stocks, Bonds & the Economy

Fed Rate Hikes: Stocks, Bonds & the Economy

Key takeaways

  • We expect the Federal Reserve to raise rates only modestly from here, but the path will depend on whether inflation broadens beyond energy and other supply-driven pressures.
  • The artificial intelligence (AI) investment boom is helping support growth and earnings, potentially reducing the need for a prolonged hiking cycle, even as inflation remains above the Federal Reserve's 2% target.
  • We suggest investors focus on oil prices, inflation trends, and credit conditions, while favoring diversified equity exposure and short- to intermediate-term bonds.

The Fed's recent rate increase may not develop into a hiking cycle as extensive as the one that began in 2022 because much of today's inflation pressure comes from supply constraints rather than broad economic overheating, where demand exceeds the economy's productive capacity. However, persistent oil-price pressure, resilient demand, or widening inflation could require additional rate increases and create greater risks for housing, credit, stocks, and long-term bonds.

With inflation remaining above its 2% target for more than five years, the Fed recently raised its benchmark rate to support a "timelier return" to its inflation goal. This is not a typical rate-hiking campaign triggered solely by excess demand. While the U.S. economy remains resilient and has seen a pick-up in activity recently, according to several leading indicators, much of the current inflation pressure comes from supply constraints, especially in energy.

Higher rates cannot produce more oil, repair disrupted supply chains, build more semiconductors, or generate more electricity. They can, however, limit the risk that the oil supply shock or AI-related investment and demand spread to wages, services prices, and inflation expectations. Containing those potential second-round effects is likely to be an important focus for the Federal Reserve.

At the same time, the U.S. economy has been supported by the AI investment boom. Spending on data centers, computing equipment, software, and research is adding to U.S. growth and offsetting some of the drag that higher rates would otherwise be expected to exert on the economy. The impact of AI on inflation, however, is more nuanced. Higher demand for semiconductors, electricity, and power infrastructure is raising costs in select producer-price categories, but there are few signs that these pressures are driving broader price increases or a change in longer-term inflation expectations.

This leaves the Fed weighing whether raising interest rates will be effective in reducing inflation. In other words, many of the forces keeping inflation elevated today originate from the supply side of the economy, where monetary policy has narrower influence.

There is an important distinction between supply-driven inflation and demand-driven inflation. If the Fed is responding mainly to supply-driven inflation rather than an overheating economy, a couple of additional increases may be needed to contain price pressures without ending the expansion. The AI capital expenditures (capex) cycle adds uncertainty to that judgment because it may strengthen near-term demand, even if it improves the economy's productive capacity over time. Even so, the likely path remains less aggressive than the cycle that began in 2022.

Our base case is for two additional rate increases, followed by a pause. But ultimately the endpoint of the hiking cycle will depend on how growth and inflation evolve. Stronger demand without a corresponding improvement in supply could require more restraint, while clearer productivity gains and easing inflation could allow the Fed to hike less than we anticipate.

The Fed will therefore need to weigh both sides of the AI dynamic alongside monthly core inflation, whether price pressures are broadening out across the economy, inflation expectations, labor-market conditions, and evidence that higher energy costs are not passing through to other goods, services, and wages.

A more aggressive or prolonged tightening cycle would most likely follow if growth remains stronger than expected while inflation stays firm, or if a worsening supply disruption or new supply-side shock broadens underlying price pressures. Conversely, softer growth or sustained disinflation—or a slowing pace of price increases rather than an outright decline in prices—would reduce the need for additional hikes. Ultimately, the precise endpoint for the Fed's rate increases is likely to be data-dependent.
