Fed chair Powell is not done telling markets where rates will go

By Ann Saphir

WASHINGTON (Reuters) - Since it began its current round of interest-rate hikes this year, the U.S. Federal Reserve has aimed to let investors know ahead of time not just where rates are heading generally but exactly how big a move to expect each time.

And despite some snags, including what analysts say was a last-minute but successfully telegraphed change of plans before the June meeting, Fed Chair Jerome Powell isn't likely to abandon those efforts.

The Fed and other central banks have long used that signaling - known as forward guidance in their parlance - to set expectations about where policy is headed to help create the financial conditions conducive to their goal. Coming out of the 2007-2009 financial crisis, for instance, the Fed set very long-term guidance that ensured rates would not rise for years.

The past year's run-in with the highest inflation in a generation has forced changes to that - in particular, shortening the horizon over which they can pledge certain actions.

"It’s a very difficult environment to try to give forward guidance 60, 90 days in advance," Powell said at a press conference after May's meeting. "There are just so many things that can happen in the economy and around the world. So, you know, we’re leaving ourselves room to look at the data and make a decision as we get there."

Indeed, other central banks are encountering similar challenges and are responding in new ways. The European Central Bank last week raised rates more than it had promised at its prior meeting and did not provide guidance for the size of next month's increase. The Bank of Canada delivered a surprise full percentage point interest-rate increase earlier this month without breathing a word in advance.

But as the head of the world's most important central bank now undertaking its sharpest bout of policy tightening in decades, Powell has a particular stake in making sure markets don't under- or over-estimate what is coming, analysts say.

On Tuesday, U.S. central bankers start a two-day meeting at which they are expected to ratify a 0.75 percentage point increase, the bigger of two possible increments that Powell weeks ago said would be under consideration.

And despite uncertainty over what data on inflation and employment in the next two months will show, analysts broadly expect Powell to put some parameters around September's rate hike decision as well.

"Monetary policy works through market expectations, and if they go haywire, you end up tightening more than you want," said Piper Sandler economist Roberto Perli. "I think it’s a tough game to play, but I think it’s reasonable for them to play."
