0) The CPI inflation number for January was flat, which was a bit less than the slight increase of +0.1% expected. However, the core inflation number—which excludes more volatile food and energy prices—gained +0.3% as opposed to an expected +0.2%. The difference was mainly due to an energy price decline in the headline figure, as well as marginal gains in apparel, tuition/child care and tobacco in the core number. Year-over-year, the headline inflation number was up +1.6% and core +1.9%. Similarly, the Producer Price Index for January rose +0.2% which was a tick below the expected +0.3% increase (and a year-over-year result of +1.4%). The core number rose by an identical amount, in line with expectations.
Overall, inflation results remain well-contained, if the CPI and PPI are used as one’s primary measures. Of course, if one uses one of the many ‘underground’ metrics available, such as one of several historical methodologies or lifestyle-based calculations, you might find a different number—but these are based on different rules and product mixes (one must also account for the technological differences implied in these assumptions). For example, our food might be cheaper, but many of us might argue cable TV, tuition and health care certainly aren’t. It’s hard to find a perfect measure here. But the differences do become important for retirees and future retirees if/when cost of living adjustments for Social Security benefits are tweaked and CPI starts to mean something. Then, those getting the benefits will begin to care about the calculation a lot. In that situation, retirees will naturally benefit from the highest (‘most realistic’) inflation number possible, while it will behoove the government (for program sustainability reasons) to keep these increases as low as possible, which may or may not track the actual inflation many of us experience on a day-to-day basis.
