Inflation and Consumer Spending

Investors don’t pay much attention to the monthly report in personal income and spending. We already have a good handle on income from the employment report. Unit auto sales and the retail sales data tell us a lot about consumer spending. However, while monthly spending figures are subject to revision, they are a direct input into the GDP calculations (and consumer spending accounts for about 69% of GDP). The personal income and spending report also include the PCE Price Index, which is the Fed’s inflationary benchmark for monetary policy. The August report confirmed a softer trend in consumer spending growth in 3Q17. The trend in core inflation moved further away from the Fed’s 2% goal.

Excluding food and energy, the PCE Price Index rose 0.1% in the initial estimate for August. That’s not a big miss relative to the median forecast (+0.2%), but it resulted in a further decline in the year-over-year change (+1.3%). One alternative measure of core inflation excludes the largest monthly moves in prices each month. Fed Chair Yellen recently noted that this trimmed-mean PCE Price Index (prepared by the Dallas Fed) “shows less of a slowdown” in inflation this year. The August figures also showed a further downtrend in the year-over-year calculation (to 1.6% from 1.9% at the start of the year).

In her September 26 speech to the National Association for Business Economics, Yellen presented a graph of the decomposition of inflation relative to the Fed’s 2% goal. In the last two years, energy prices, import prices, and labor market slack put downward pressure on headline inflation. Those factors have all but disappeared. Energy prices have firmed. The dollar’s decline has lifted prices of imported supplies and raw materials. Wage pressures have remained moderate, but clearly the job market has grown tighter. The Atlanta Fed’s Wage Growth Tracker has picked up over the last year.
