Projections read as promises

That misreading carries a cost for the Fed as well. Policy makers can feel compelled to follow through on their projections, which makes the Fed slow to respond when conditions change. Forward guidance helps markets understand where things are headed and can be counterproductive when conditions shift unexpectedly.

Why the dots fall short

The dot plot also forces policy makers to give precise forecasts without any way to convey how uncertain they are. Chairman Powell had reservations about it and about how investors misunderstand it, but reform efforts stalled because the committee struggled to find a better alternative.

Warsh drops the dots

In his first few weeks as Fed chairman, Warsh declined to submit a dot plot projection and announced a broad review of Fed communications.

How is the Fed's dot plot built?

Each participant in the Federal Open Market Committee submits an anonymous projection of where the federal funds rate should stand at the end of the next few years. Each projection is plotted as a single dot on a chart, with no names attached. The chart is published four times a year as part of the Summary of Economic Projections, and the Fed first published it in January 2012. The committee has 19 participants, though not all of them vote on rate decisions in a given year.

Why did the Fed start giving forward guidance?

After the Fed cut its policy rate to near zero in December 2008, it had no room to cut further. It turned to forward guidance, which means telling markets how long rates would stay low, to influence longer-term borrowing costs. Longer-term interest rates reflect what investors expect short-term rates to do over many years, so statements about the future path can move them. The approach became a standard tool at central banks around the world.

Why do markets move on Fed projections?

Bond yields and mortgage rates are tied to expectations about future short-term interest rates. A projection that shows fewer or more rate cuts than investors expected pushes those expectations, and prices adjust within minutes. Economists call this the expectations channel of monetary policy. Because the dots are published at the same time as the committee's rate decision, traders read them in real time.
