This week’s roundup of the US economy and stock market covers record traffic at the Port of Los Angeles, the drop in Americans who say they drink alcohol, government spending as a share of GDP across OECD countries, September’s inflation report, and how rising stock prices have shifted household wealth.

The S&P 500 bull market has reached its fourth anniversary, making it the eighth-longest since World War II. Since 1974, every S&P 500 bull market that reached its fourth anniversary has gone on to complete a fifth year, with the four most recent cases delivering double-digit gains without a correction exceeding 10%.

The S&P 500 has gone over 50 trading days without a 1% decline, and the NYSE has recorded over 220 consecutive sessions without declining stocks accounting for at least 80% of trading volume, the longest such streak since at least 1996.

 

The Fed

 

Headline inflation accelerated to 0.65% month over month in September, in line with consensus. However, core inflation rose by 0.33% month over month, hotter than expected. AI-related imports, tariff front-running, shipping disruptions, and a spike in fuel prices have fueled acyclical inflation, according to Bank of America. Gasoline price inflation accelerated amid elevated energy prices and ongoing Middle East tensions. Food inflation, however, eased. Ground beef prices leveled off but stayed above $7 per pound for the sixth consecutive month.

Turning to components of core inflation, core goods prices increased for a third straight month, led by both new and used vehicles.

Prices for computers and peripherals continued to rise amid price hikes for several Apple products. Shelter inflation accelerated last month, with owners’ equivalent rent (OER) contributing 12 basis points to month-over-month core inflation.

Markets increased their bets on Fed tightening following the CPI release, with the implied probability of an October rate hike rising to 34% and approximately 30 basis points of cumulative tightening priced in by year-end.

Mortgage applications edged lower as the 30-year fixed mortgage rate increased.
