CPI Rises Less Than Expected But Year-Over-Year Numbers Remain Elevated

The CPI rose less than expected in three of four categories vs the Bloomberg econoday consensus. Year-over-year numbers remain problematic.

  • The Consumer Price Index for All Urban Consumers (CPI-U) increased 0.3 percent in August on a seasonally adjusted basis after rising 0.5 percent in July.
  • The indexes for gasoline, household furnishings and operations, food, and shelter all rose in August and contributed to the monthly all items seasonally adjusted increase.

Econoday Economist Expectations


  • The consensus opinion was for the CPI to rise 0.4% month-over-month vs. the reported 0.3%
  • The consensus opinion was for the Core CPI to rise 0.3% month-over-month vs. the reported 0.1%
  • The consensus opinion was for the CPI to rise 5.3% year-over-year vs. the reported 5.3%
  • The consensus opinion was for the Core CPI to rise 4.2% year-over-year vs. the reported 4.0%

The Real CPI

The CPI factoring in housing and medical is much greater than the reported CPI. I will publish an alternate CPI that factors in housing when the next Case-Shiller home price data is released. 

My last report had year-over-year CPI at 8.57%. For discussion, please see Housing Adjusted Real Interest Rates Sink to a Record Low -8.5 Percent.

Stay tuned.

Month-over-month the CPI fell 0.1%. Year-over-year, vs. easy comparisons, the CPI rose 2.4%. Treasury reaction: big yawn

CPI Rises Modest 0.2%, 2.5% from a Year Ago: Your Results May Vary Dramatically

The CPI rose 0.2% in April vs the economists' expectation of 0.3%. Year-over-year the CPI is up 2.5%.

Industrial Production Much Stronger than Expected

Industrial production rose 0.6 percent vs the Bloomberg Econoday consensus estimate of 0.2 percent.
