Fed Study Finds 9% Chance of Rates Hitting Zero in Medium Term

New York Fed researchers, including President John Williams, estimate a 9% probability that the federal funds rate will return to the zero lower bound over a seven-year horizon. This finding, highlighted in a recent blog post, suggests the Federal Reserve cannot discount the possibility of rates hitting zero again, a risk exacerbated by current interest-rate uncertainty.

Analysis

A New York Fed study, co-authored by President John Williams, introduces a significant medium-term consideration for monetary policy, estimating a 9% probability of the federal funds rate returning to the zero lower bound (ZLB) within a seven-year horizon. This finding is particularly salient as it originates from within the central bank, signaling that policymakers have not dismissed the potential for a future scenario requiring a return to maximum policy accommodation, despite the current focus on combating inflation. The report explicitly links this risk to the "current high level of interest-rate uncertainty," suggesting that the path for growth and inflation remains highly unpredictable. While a 9% probability does not represent a base case, it constitutes a non-trivial tail risk that challenges a simple "higher-for-longer" rate narrative and underscores the Fed's own acknowledgement of future economic fragility.

Key Decisions for Investors

• Investors should consider this 9% probability of a return to the ZLB as a potential medium-term tailwind for long-duration assets, which would benefit significantly from such a monetary policy shift.
• Given the Fed's acknowledgement of high interest-rate uncertainty, it is prudent to ensure portfolios are diversified and not overly concentrated in assets that perform well only in a sustained high-rate environment.
• Monitor the shape of the yield curve closely, as any increase in the perceived probability of a future ZLB event could lead to a flattening bias or renewed inversion, signaling changing medium-term growth expectations.
