Monetary Policy Schocks: A New Hope Large Language Models and Central Bank Communication
Researchers have developed a new method to measure monetary policy surprises using a multi-agent Large Language Model system to analyze the Federal Reserve’s public documents, such as Beige Books and Federal Open Market Committee (FOMC) Minutes. This approach explains over 50 percent of policy rate changes, far surpassing traditional market-based methods. The system offers real-time, transparent insights and enables more accurate predictions for economic and financial impacts, though it may miss private information available only to the Fed.
What it examines
This paper introduces a new method using large language models (LLMs) to analyze Federal Reserve communications and measure unexpected monetary policy decisions. By processing documents like the Beige Book and Minutes before each meeting, the approach aims to create cleaner, more accurate measures of policy surprises than traditional market-based methods.
What it concludes
The results show that LLM-based analysis provides more reliable and timely identification of monetary policy shocks, leading to better economic predictions and trading strategies. This method can help central banks, researchers, and financial professionals understand and react to policy changes, and could be adapted for other areas involving important institutional communications.

This paper presents a novel multi-agent LLM framework for extracting conditional expectations from Federal Reserve communications, enabling construction of narrative monetary policy surprises. Its originality lies in combining LLMs, narrative identification, and real-time analysis, yielding theoretically consistent, less noisy policy shock measures with significant implications for macroeconomics, finance, and AI-driven trading strategies.
