Fed study warns of risk that interest rates return to zero

A new Federal Reserve study from the New York and San Francisco branches estimates a nearly 1-in-10 (9%) probability that benchmark interest rates will return to zero by 2032, a significant increase from 1% over the next two years. This research, which utilizes SOFR derivatives pricing, highlights how rising economic uncertainty elevates the risk of hitting the zero lower bound, potentially leaving the Fed with limited policy space to effectively counter future economic downturns despite current rates being well above zero.

Analysis

A new Federal Reserve study, co-authored by New York Fed President John Williams, indicates a material risk of US interest rates returning to the zero lower bound (ZLB) in the medium term. Based on pricing from SOFR derivatives, the research projects a nearly one-in-ten (9%) probability of this scenario by 2032, a significant increase from the roughly 1% risk priced in for the next two years. This elevated long-term risk persists despite current market expectations for the benchmark rate to remain in the 3% to 4% range over the next several years. The core driver identified is heightened economic and policy uncertainty, with the report citing trade tariffs, geopolitical tensions, and questions over Fed leadership as contributing factors. The findings highlight a critical challenge for the central bank: its policy space to combat a future economic downturn may be more constrained than current rate levels suggest, as persistent uncertainty could force a rapid return to an ultra-low rate environment.

Key Decisions for Investors

• Investors should consider the strategic value of long-duration assets, such as long-term government bonds, as a potential hedge against a medium-term return to a zero-rate environment where conventional monetary policy is less effective.
• Portfolio managers ought to re-evaluate long-term models for rate-sensitive sectors, accounting for the divergence between stable near-term rate expectations and the rising medium-term probability of a return to the zero lower bound.
• It is prudent to closely monitor indicators of policy and economic uncertainty, as the Fed's research suggests these are primary drivers that could rapidly increase the market-priced probability of hitting the ZLB.
