Before each FOMC meeting, traders and investors attempt to predict what the committee will decide, drawing on economic data and market signals. When the Fed's decision catches markets off guard, economists call this gap a "monetary policy surprise." These surprises are measured by how much
federal funds futures contracts move in the minutes around an FOMC announcement.
Why surprises are predictable Puzzlingly, these surprises turn out to be partly predictable from information available before meetings. Economists have offered three main explanations. First, the Fed may know more about the economy than markets do. Under this view, the Fed's policy choices gradually reveal its private information to the public. Supporting this idea, stock prices often rise after surprise rate hikes, as if investors take the Fed's willingness to tighten as a positive signal about the economy. Second, markets may underestimate how strongly the Fed reacts to economic news, especially during downturns. Third, the Fed may not react directly to individual data releases at all. Instead, it may watch how those releases ripple through financial markets before deciding what to do. If markets expect a more immediate response, surprises become predictable. This view is consistent with findings that financial stress indices, such as those published by the
Office of Financial Research and the
Federal Reserve Bank of St. Louis, help forecast FOMC decisions.
Role of financial conditions Fed Chair
Jerome Powell touched on this issue during his May 3, 2023 press conference. He noted that the Fed does "look at financial conditions very broadly" because "they're important for the achievement of our goals," but added that the Fed does not target financial conditions directly. Instead, it treats them as "an important piece of information in assessing the likely path of the economy." Similar remarks appear in FOMC meeting minutes and other Fed communications. One study finds that the Fed tends to wait before acting on new economic data, especially data released within two weeks of a meeting. Rather than responding right away, the committee appears to let the news settle into broader market conditions first. This pattern is consistent with how the Fed describes its own approach: watching how data affects the overall economic outlook rather than reacting mechanically to any single release. == Consensus ==
