Shortly after the open, the S&P 500 fell more than 2%, the Dow closed up 1.7%, while the tech-heavy Nasdaq fell 2.8%. The Bureau of Labor Statistics released the Consumer Price Index (CPI) for August early Tuesday, which showed prices rose 8.3 percent from a year earlier and 0.1 percent from the previous month. Economists had expected an 8.1% increase in inflation compared to last year and a 0.1% decrease compared to the previous month. That measure signals some slowdown in price increases – which hit four-decade highs earlier this year – but this smaller-than-expected drop will likely secure another 0.75% rate hike from the Federal Reserve at its policy meeting on next week. On a “core” basis, which excludes the more volatile food and energy costs, prices rose 6.3% from a year ago in August and 0.3% from the previous month. Much of the steady increase in core inflation came from housing costs, which rose 0.7% last month in August, the most since January 1991. Housing costs make up about a third of the CPI. “Core inflation has peaked but, in a clear sign that the need to continue hiking rates is unabated, core CPI is once again on the rise, confirming the very sticky nature of the US inflation problem,” Seema said.

After Tuesday’s report, data from the CME Group showed investors were pricing in an 82% chance of a 0.75% rate hike next week and an 18% chance of a 1% rate hike. Last week, these figures reflected a 75%-25% split between a 75 basis point and 50 basis point rate hike. Movements along the Treasury curve were also sharp on Tuesday, with the 10-year yield rising to around 3.44%, while the 2-year yield rose 15 basis points to 3.72%.
