The Inflation Update: March 2005
Stephen G. Cecchetti

A headline in this morning’s Wall Street Journal reads “Housing Starts Fell 17.6% in March.”  For those of us who watch data daily, this served as a reminder to look at trends.  Monthly data are very noisy, and when they are annualized, any small data anomaly tends to be magnified.  (In the case of housing starts, the trend is still increasing.)

This lesson was repeated with this morning’s CPI report which contains some of the same data problems.  The fact that the all-items Consumer Price Index rose at a 7.8% annual rate (a.r.) for the month of March is really no cause for panic.  Core inflation measures rose quite a bit as well, with the CPI excluding food and energy up 4.3% (a.r.) and the Median CPI computed by the Federal Reserve Bank of Cleveland was up 2.8% (a.r.).  All of these readings were well above their 12-month averages (3.1% for the headline CPI, 2.3% for the traditional core, and 2.4% for the Median CPI.)

Nevertheless, inflation is up at least one-half of one percentage point from a year ago and there are signs that its trend continues to rise.  Owner equivalent rents rose 3.2% (a.r.) for the month, well above its 2.4% average over the year.  And other service prices rose even more rapidly, with the index for services excluding energy services rising 5.8% in March. Then there is medical care. Over the past 12 months, that index is up 4.3% and rising.

The one bright spot in the report is that core goods prices (commodities excluding food and energy commodities) were unchanged for the month.  After rising at an annual rate that looked to be in the range of 1%, we are now seeing a brief respite.  But countering this is the 60.9% (a.r.) increase in energy prices (see what computing annual rates does!).   Unless oil prices fall, eventually this will feed through to other prices.

Apparel provides an interesting example of the problems we data-watchers face.  After falling nearly continuously for five years, the index for apparel was unchanged over the past 12 months.  The elimination of textile quotas, together with the Chinese decision to continue to peg the yuan to the dollar, has not driven apparel prices down.  The problem is that the domestic content of imported goods, especially low priced ones, is quite high.  Clothing made in Asia has to be transported inside the U.S. and then sold through American retailers. Final consumers can pay as much as four times the price at the border.

Today’s data are additional fuel for the battle that is currently being waged at the FOMC.  The minutes of the March 22 meeting (released last week) described significant disagreements.  While some participants expect core inflation readings to remain subdued, others are concerned that the last few years of very low interest rates are starting to have an impact. Inflation risks have now shifted further to the up side, making it even more urgent that interest rates rise to at least 4% in the near term.  In fact, unless FOMC members are willing to accept inflation of 3%, we are likely to see a federal funds rate of 5% some time next year.
