The aggressive policy path will kick off with a half-percentage-point rate hike on Wednesday.

But what is this neutral rate?

For months, talk has centered around a 2.4% rate. Some Fed officials have pointed to it. It squares with the Fed’s quarterly economic forecast of the “longer run” Fed funds policy rate. that put the “longer run” Fed funds rate at 2.4%

But that’s not the right measure for neutral, said Andrew Levin, an economics professor at Dartmouth College and a long-time Fed staffer, including a role as a special advisor on monetary policy strategy and communications to the Fed board between 2010 and 2012. He currently advises the central banks of Norway and Sweden and also is a visiting scholar at the International Monetary Fund.

With the core measure of the Fed’s favorite inflation gauge running at 5.2%, that means the neutral funds rate is actually in the range of 5%-6%, Levin said, in an interview.

The 2.4% rate that is often cited is really only the “neutral” level when inflation is running at the Fed’s inflation target is at 2%, he added.

A guiding principle of fighting inflation is actually spelled out on the Fed’s website, in a section entitled, “Principles for the Conduct of Monetary Policy.“

It reads: “The central bank should raise the policy interest rate, over time, by more than one-for-one in response to a persistent increase in inflation and lower the policy rate more than one-for-one in response to a persistent decrease in inflation.” For example, if the inflation rate rises from 2% to 3% and the increase is not caused by temporary factors, the central bank should raise the policy rate by more than one percentage point. 

Core PCE inflation has moved up to a 5.2% annual rate in March from 2% in the same month from last year.

Of course the key is how much of the recent surge in inflation is temporary. That remains to be seen, although the Fed has already been burned by calling the price rises last year “transitory.”

Powell should say that, while there is a lot of uncertainty, the Fed “needs to move to a neutral stance which means we need to move the federal funds rate to be roughly in line with, or slightly above, the level of inflation,” Levin said.

“If Powell would communicate that on Wednesday, I think the markets will understand that probably the federal funds rate is going to have to go up to 4% or 5% by the end of the year,” he said.

Market expectation, based on the CME’s Fed Watch tool, is that the Fed will raise its policy rate to a range of 3%-3.25% by the end of the year and rates will go to a range of 3.5-3.7% by July 2023.

Economists at Deutsche Bank see the Fed raising interest rates up to 3.6% by the mid-2023. When combined with the effects from the winding down its balance sheet, which have similar impacts of rate hikes, the Fed will deliver more than 4 percentage points in effective tightening, the Wall Street bank estimates.

“This tightening should begin to materially slow growth in the second half of the 2023 and induce a recession that begins late next year,” said Matthew Luzzetti, chief U.S. economist at Deutsche Bank, in a note to clients.

“We will be interested to hear how the FOMC is interpreting the appropriate nominal neutral rate in an environment where inflation is considerably above the Fed’s 2% target,” he added.

Some fixed-income expects believe the Fed’s benchmark rate could hit 6%, while other economists and strategists think the Fed won’t be able to raise rates even to 3%.

Ellen Gaske, lead economist at PGIM Fixed Income, said she thinks, subject to a lot of uncertainty, that the Fed will raise rates only to 2% by the end of this year and 2.5% in 2023.

She said firms will lose their pricing power and that there will be a bit of moderation on wage gains.

These views are informed by the Fed’s last tightening cycle, where the Fed tried to get rates up to a “neutral” – which it said was around 3% – but did a U-turn after rates hit a range of 2.25%-2.5% in December 2018 and financial markets swooned.

Marvin Loh, senior global macro strategist at State Steet, said the Fed is going to stop hiking rates “somewhere in the range of 2.25%-2.5% range” either late this year, or early next.

“I think that is as high as it goes,” he said.

Loh said there could some friendly inflation prints later this year. “I do think that there is a chance that we have seen peak inflation, and then it really become a question of how quickly it comes down,” he said.

Loh said he doesn’t think the economy will be able to be able to withstand much tighter financial conditions and there is a chance core CPI gets into the 4% range by the end of the year.
