Warsh Warns on Inflation at Jackson Hole, Raises Prospect of Rate Hike

JACKSON HOLE, Wyo., Federal Reserve Chairman Kevin Warsh sharpened his inflation warning Friday in his first keynote address at the annual Jackson Hole Economic Policy Symposium, telling an audience of central bankers and economists that price pressures remain the central bank's primary concern and leaving open the possibility of a rate increase at the Fed's September meeting.

Warsh, who took office as Fed chairman on May 22, delivered the remarks on the third day of the three-day symposium hosted by the Federal Reserve Bank of Kansas City. The event ran Aug. 27-29 in Moran, Wyo., and drew roughly 120 officials and economists from more than 70 countries, according to organizers.

The chairman said he was "impressed" with the economy's overall strength but flagged that "underlying trends" in inflation had not improved, according to remarks posted on the Federal Reserve's website. He declined to signal a specific rate path, doubling down on his refusal to offer what he called "forward guidance", a practice his predecessor Jerome Powell used regularly.

"A quieter Fed, more purposeful in its communications, is better able to meet its objectives," Warsh said Friday, according to CNN Business.

The Fed's preferred inflation gauge, the personal consumption expenditures index, stood at 3.7% year-over-year in July, which Warsh called "concerning," according to Fox Business. The consumer price index showed prices up 3.4% over the 12 months ending in July, according to NPR. Both measures sit well above the Fed's 2% target.

Warsh pointed to the breadth of price increases across the economy, noting that 54% of PCE components had run above 3% annualized inflation over the past 12 months, according to CNBC. He reaffirmed 2% as the Fed's "firm, fixed target" for the PCE index, according to Fox Business.

Markets interpreted the speech as more hawkish than Warsh's July news conference, which traders and analysts had faulted for leaving the Fed's reaction function unclear. Bond markets priced in a rate hike swiftly after the speech ended. Traders lifted the probability of a rate increase at the Sept. meeting to 55.7%, roughly 20 percentage points higher than the day before, according to the CME Group's FedWatch tool cited by CNBC.

Heather Long, chief economist at Navy Federal Credit Union, told CNBC that Warsh "opened the door to a Fed rate hike" but that one "probably won't come in September", more likely October or December.

Seema Shah, chief global strategist at Principal Asset Management, said in a statement cited by Fox Business that Warsh "untangled much of the ambiguity left by the July FOMC press conference, presenting a clearer picture of a Fed that remains laser-focused on returning inflation to target and is prepared to raise rates if progress stalls."

The Washington Post reported that a majority of investors now expect a rate hike in September, though Warsh stopped well short of clearly committing to one.

The speech put Warsh at odds with President Trump, who has repeatedly called for lower borrowing costs, according to CNBC. The White House did not immediately respond to a request for comment Friday.

Warsh's first pair of news conferences as chairman had already unsettled bond markets. The 30-year Treasury yield closed at 5.31% on Aug. 17, its highest level since 2007, according to REX Shares. The Treasury Department intervened in the bond market two days later in an attempt to bring long-term borrowing costs down.

The Fed's next policy meeting is scheduled for mid-September. No rate decision was made at Jackson Hole, which is a forum for policy discussion rather than a rate-setting meeting.
