Criticisms of the Fed's Summary of Economic Projections (SEPs) for inaccuracy miss their primary value for markets. The SEPs provide crucial insight into the committee's 'reaction function'—how it will likely adjust policy in response to economic data deviating from its baseline, which is more valuable than the forecast itself.

Austan Goolsbee clarifies a key distinction in Fed communication. He supports communicating the Fed's "reaction function"—its worldview and how it interprets data. He opposes "forward guidance," which he defines as pre-committing to future rate moves, as it ties the Fed's hands and increases volatility.

A more aggressive Federal Reserve reaction function is interpreted as a tightening signal by inflation markets. This leads to lower inflation break-evens and higher real yields, a counter-intuitive move compared to when the Fed and markets react in tandem to strong economic data.

Instead of dictating future moves ('forward guidance'), the Fed can explain its data-driven decision framework ('reaction function'). This allows markets to price in changes as data is released, effectively pre-empting and amplifying Fed policy.

Unlike past cycles where consumer savings react with a lag *after* policy changes, the Fed's constant forward guidance about future cuts caused savings to decline preemptively. This demonstrates the immense power of central bank communication in shaping immediate consumer behavior.

Despite rising inflation in 2021, financial forecasters consistently expected policy rates to remain at zero. It was only after the Federal Reserve initiated rate hikes in 2022 that market participants updated their perceived policy reaction function. pflueger identifies this dynamic as the 'learning from actions channel,' showing that communication alone failed to shift expectations until concrete rate changes occurred.

By reducing forward guidance, the Fed forces markets to react to economic data rather than trying to predict policy statements. This discomfort is healthy, as it makes market prices an independent and valuable signal for the Fed to learn from, breaking the cycle where the Fed dictates market interpretation.

When questioned on the effectiveness of one 25bps cut for the labor market, Fed Chair Powell replied it would do "nothing" but that "it's the path that matters." This statement implies the Fed is not making a one-off adjustment but beginning a deliberate easing cycle.

When the market clearly grasps the Federal Reserve's policy reaction function, bond yields automatically adjust following economic data releases like CPI or employment. This dynamic allows markets to implement monetary conditions aligned with Fed intentions ahead of FOMC meetings, effectively doing the central bank's transmission work in advance.
