On Friday, the Bureau of Labor Statistics released Consumer Price Index data for September. While the annualized month-over-month CPI inflation rate fell (from 4.69% in August to 3.79% in September), the annual rate rose (2.94% to 3.02%) as did our measure of trend (from 3.18% to 3.38%).
Core CPI inflation provides a glimmer of good news: the monthly, annual and trend rates all fell. The annualized monthly inflation rate fell from 4.23% to 2.76; the anual rate from 3.11% to 3.03%, and our trend from 3.38% to 3.17%.
Policy Outlook
Rather than speculate as to what the FOMC is likely to do with its policy rate at its upcoming meeting, we’ll focus on what the committee should do. Keep in mind that the FOMC primarily looks at core PCE inflation, not (core) CPI inflation. However, the PCE data is not scheduled to be released until Friday while the committee meets Tuesday and Wednesday. (Given the federal government shutdown, we were taken by surprise when the BLS released the CPI numbers; we have no idea whether the BEA will similarly release the PCE data on Friday.) Keeping in mind that on average CPI inflation runs ½ percentage points higher than the corresponding PCE inflation rate, our trend measure of core CPI inflation for September suggests that trend PCE inflation can be expected to be around 2.7% – 0.7 percentage points higher than the FOMC’s target of 2%. Alternatively, if the change in trend core PCE inflation is the same as for trend core CPI inflation (0.2 percentage points), expect a PCE inflation rate just over 2.6% – again higher than target. Further lowering the Fed’s policy rate is not warranted given these inflation numbers. As many know, the Fed has a dual mandate and has indicated that the risks of a labor market slowdown has become a major factor in the decision making process. Unfortunately, the BLS has not released the latest employment numbers.
