Warsh's Hawkish Tone Sparks 66.1% Chance of September Rate Hike

Federal Reserve Chairman Kevin Warsh's speech at the Jackson Hole symposium in Wyoming has reshaped expectations for an interest rate increase in September. According to CNBC, markets initially saw little likelihood of a hike before December, but after Warsh's speech, they assigned a high probability to action when the Federal Open Market Committee meets on September 15-16.

The odds of a move at that meeting rose to 66.1% on Monday, nearly twice their level before Warsh spoke, according to CME Group's FedWatch. Warsh said recent soft inflation readings do not show that 'underlying trends have meaningfully improved.' He emphasized that policymakers must be confident that inflation is moving toward their objective 'clearly and at sufficient speed,' or 'we have work to do.'

However, some economists and officials questioned whether the market reaction was warranted. Treasury Secretary Scott Bessent argued that core inflation had remained 'very, very restrained' and that policymakers traditionally do not raise rates into a supply shock unless they see second- or third-order effects. Citigroup economist Andrew Hollenhorst said Warsh's comments were only marginally more hawkish than usual.

The Fed will receive additional labor, housing, consumer spending, and inflation reports before its decision. Some experts remain cautious about the employment picture, which could discourage rate increases, while others believe that absent a material downside surprise, the chairman faces pressure to deliver a September increase.
