Fed crisis interventions impact market fear term structure
A new Bank of Canada working paper examines how Federal Reserve crisis interventions impact market fear. The study finds that these interventions reduce the perceived risk of large asset price drops via distinct risk and information channels.
Two channels of fear reduction
The paper develops a methodological framework to evaluate the causal effect of unexpected Federal Reserve actions on market fears, defined as the perceived risk of large asset price drops.
Researchers extract daily fear term structures from options markets, with event horizons ranging from two weeks to ten years.
High-frequency price movements around crisis announcements for a wide range of financial assets—including FX, equity, and fixed income markets—are used to isolate the shock component of Fed interventions.
By classifying these shocks into five policy groups, the study measures the heterogeneous effects of various crisis tools.
Applying this to the market turmoil of 2020, the authors find that the Fed impacts market fear via distinct risk and information effects.
The risk channel, primarily driven by asset purchases, dominates at short to medium terms.
In contrast, the information channel, operating through interest rate policies, dominates at longer terms.
This suggests different policy tools have varying effectiveness across the term structure of market fear.
Unconventional tools in 2020 turmoil
The study specifically examines the extreme market turmoil of 2020, a period selected because it necessitated the deployment of central bank crisis tools and marked the first time a broad range of non-conventional Federal Reserve instruments were fully available.
Researchers utilized a unique dataset from over-the-counter (OTC) options markets, allowing them to capture tail risk perceptions across horizons from two weeks to ten years.
A key methodological challenge involved isolating genuine Fed announcement effects from other concurrent market developments.
This was addressed through high-frequency identification, measuring immediate price changes across various financial assets around Fed announcements to pinpoint the surprise component of interventions.
Fear gauge reveals policy nuances
This paper provides a crucial, granular understanding of how central bank interventions influence market psychology beyond immediate asset price effects.
The identified distinction between risk and information channels, with their varying term structures, offers valuable insights for policymakers crafting future crisis toolkits.
This robust methodological framework, though focused on the 2020 turmoil, sets a precedent for analyzing central bank effectiveness in mitigating systemic fear.
