This brings us to Warsh, who has been in the hot seat for only three months. He has vowed to shake up the central bank’s communications strategy, which he believes has swung too far toward the Bernanke end of the spectrum: too many speeches and public comments from Fed officials, too much "spoon-feeding" of information to markets, and too many policy meetings.
One of the five task forces he has set up to overhaul Fed operations is focused on fixing this. Its rather dull title – "Communications: Review how the Federal Reserve conveys policy deliberations and decisions amid uncertainty" – belies the huge market impact a radical shift in Fed communication could have.
In his Friday keynote address at the Kansas City Fed's annual symposium in Jackson Hole, Wyoming, Warsh said that "a quieter Fed, more purposeful in its communications, is better able to meet its objectives."
Over the past 30 years, Fed communication has evolved in the direction of greater transparency – even under Greenspan. In 1999, "The Maestro" oversaw the Federal Open Market Committee's move to issue a statement after every policy decision.
But the major inflection point was the GFC. This crisis – the worst U.S. financial collapse since the Great Depression – marked a huge shift in how the Fed operated. It slashed interest rates to zero and pumped trillions of dollars of liquidity into the financial system via massive bond-buying, or so-called quantitative easing.
Explaining all that to the public – and keeping investors calm — was no easy task. Consequently, Bernanke’s Fed rolled out a host of new tools, and forward guidance truly came of age. He introduced the Summary of Economic Projections (SEP) in 2007, FOMC press conferences in 2011, and the much-maligned "dot plot" of officials' anonymized forecasts of key economic variables, including GDP growth, inflation, unemployment and interest rates, in 2012.
The Bernanke Fed also formalized the 2% inflation target in 2012. That had been an assumed target since the mid-1990s but had previously never been made official.
On top of all this, the Fed chair delivers semi-annual testimony to Congress, there are press conferences after every meeting, minutes of every FOMC policy meeting are published, and Fed governors and regional Fed presidents give speeches and regular interviews to print and TV media. There are up to 19 participants in FOMC meetings, so that's a lot of public appearances. Too many, Warsh says.
He might be right, but any transition will be difficult.
