Chicago Federal Reserve Bank President Austan Goolsbee on Friday left the door open to supporting an interest-rate cut in September should fresh data prove reassuring, but said recent reports showing a rise in services inflation give him some pause amid what he calls the "stagflationary" impulse from tariffs.

Inflation held steady in July and ran slightly cooler than expected, increasing the odds of a Federal Reserve rate cut next month.

Goldman Sachs economists in a note estimated that consumers could soon bear up to 67% of tariff costs, up from 22%, thus escalating broader inflation risk. Before the Aug. 14 PPI report, markets were nearly unanimous in pricing a September Fed interest rate cut of up to 0.50%.
