Fed Rate-Hike Cycle: Economists Debating Depth of Monetary Tightening

The Federal Reserve has initiated a rate-hiking cycle and economists are debating how far it will extend. According to Ian Lyngen of BMO Capital Markets, two additional 25-basis-point rate hikes at the October and December meetings would push the federal funds rate target range back to 4.25%, 4.5%. This would effectively reverse the rate cuts implemented in 2025 under former Fed Chair Powell.

Vanguard's Josh Hirt considers three consecutive hikes a 'reasonable starting point' for assessing the Fed's trajectory, but notes that the potential number of hikes could range from one to six.

Economists agree that once rate hikes begin, policy inertia often drives multiple consecutive actions. Lyngen's baseline forecast calls for 25-basis-point rate hikes in July, October, and December, which would return the federal funds rate to its peak before the rate cuts at the end of 2024.

The AI spending boom is a major concern in this rate-hiking cycle, with AI 'hyperscaler' tech companies estimated to incur annual capital expenditures of up to $1 trillion over the next few years. A rise in long-term interest rates will directly increase borrowing costs for these firms, compressing investment returns.

Another risk point is the insurance industry's significant holdings in private credit, which could lead to losses and systemic transmission if the interest rate environment causes sharp fluctuations.
