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.

The Fed is abandoning its 15-year strategy of using detailed "forward guidance" to suppress market volatility. This shift under new leadership towards more succinct communication suggests a new market regime characterized by higher interest rate volatility and less Fed hand-holding.

The new Fed Chair's plan to reduce "forward guidance" removes a source of market certainty. Without explicit signaling about future policy, every new economic data point will have a greater potential to shift market sentiment, leading to higher volatility even if the Fed takes no action on rates.

The push to limit forward guidance, reduce press conferences, and silence dissenting Fed presidents is not just about improving clarity. It's a strategic move to centralize messaging and control the narrative within the Fed Chair's office, thereby increasing their personal influence over policy direction and market expectations.

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.

Kevin Warsh's confirmation hearings suggest a potential regime change at the Fed. He has indicated possible shifts in how inflation is measured (using trimmed mean), the size of the balance sheet, and a reduction in market communication like forward guidance.

If the new Fed Chair reduces formal communication, markets won't simply wait in the dark. An information vacuum will emerge, which investors will fill by latching onto any official who is willing to speak. This effectively creates a "shadow Fed chair," leading to inefficient and volatile market communication.

New Fed Chair Kevin Warsh has signaled a desire to reduce transparency by potentially ending press conferences. This would be a major reversal of a multi-decade trend towards more openness. Since current traders have only known a highly transparent Fed, such a change could introduce significant uncertainty and volatility into markets.

Warsh believes the Fed relies too heavily on forward guidance, particularly the 'dot plot,' which he feels boxes in members. He will likely downgrade or eliminate it and encourage Fed presidents to speak less publicly, aiming for more agile and less predetermined monetary policy decisions.
