Institutional Insights - Goldman Sachs SP500 CPI Scenario Analysis

GS Research: We expect a 0.31% increase in October core CPI (vs. 0.3% consensus), corresponding to a year-over-year rate of 3.30% (vs. 3.3% consensus); link.

• Our October core CPI forecast is roughly in line with the pace of the August and September readings but above the +0.14% average of the three readings before that. Those softer readings were aided by large declines in the airfares component—which declined 3.4% on average— and the used cars component—which declined 1.1% on average. In October, we expect increases in airfares (+1.0%)—reflecting a modest boost from residual seasonality and strong pricing trends—and used car prices (+2.5%)—reflecting a rebound in auction prices. • We highlight two additional key component-level trends we expect to see in this month’s report.

1. We expect another firm increase in car insurance prices, reflecting continued, albeit decelerating, increases in premiums.

2. We expect the health insurance component to remain roughly flat this month as the BLS incorporates updated source data on insurance premiums.

3.Going forward, we expect monthly core CPI inflation around 0.2% for the rest of the year.
