The Inflation Update: April 2005

This morning’s inflation report can be read two ways.  For people who don’t believe that inflation has picked up, it provides comfort. For those who think that inflation really is rising, it looks like noise.

On their face, the data are soft.  While the all-items CPI rose at 6.4% at an annual rate for the month of April, it looks like it was mostly oil.  Energy prices (accounting for 8% of the index) rose at a 70% annual rate.  As a result, core inflation was much more subdued.  The CPI excluding food and energy rose 0.6% (a.r.), substantially below it’s 12-month average of 2.2%. Meanwhile the Median CPI computed by the Federal Reserve Bank of Cleveland increased 2.2% (a.r.), very near its 3-month average of 2.6%.

The primary explanation for the moderation in inflation moderation is the behavior of owner equivalent rent.  OER rose 1.6% (a.r.), well below it’s recent average of 2.3%.  This is an unusual move for a series that is this sluggish. Energy costs are the explanation has.  Remember, OER is based on rental survey, and rents generally include utilities.  When energy prices rise, rental indices fall.  Heating and electricity costs, one-tenth of housing costs, rose 28% (a.r.) in the month.  The impact of this was to cut OER nearly in half.  That is, if energy prices had risen at the same rate as everything else, OER would have gone up in the neighborhood of 3%.  That’s more in line with what most people would have expected to see.

Falling hotel prices are another source of misdirection in this morning’s release.  The decline of
-13.4% completely masks a steep upward trend.  This series is notoriously difficult to seasonally adjust.  If we look at the last 12 months, the increase is 5.5%.  That number seems more reasonable.

Core goods (commodities excluding food and energy commodities) fell at a -0.8% (a.r.) for the month, providing a modest bright spot in the report.  A substantial decline in always volatile apparel prices, which fell at a -6.7% annual rate, coupled with a decline in the prices of durable goods
(-2.1% a.r.), is responsible.  But recent changes in policies toward China – both the reimposition of textile quotas and the increased insistence on a yuan revaluation – seem intent on fixing both of these in the near future.  The result will be a return to goods price inflation.

One way to quantify these bits and pieces is to look at an alternative core inflation measure, the 16% trimmed mean. This gauge is rising, up 3.3% (a.r.) in April and 2.3% for the past 12-months.

All-in-all I doubt much has changed.  The inflation trend remains at what I believe to be the upper end of policymakers’ comfort range – nearly 2.5%.   So, it seems reasonable to expect continued interest rate increases.  When will the Committee stop?  Current financial-market expectations are for a federal funds rate target of 3.75% by the end of this year.  That’s 3 increases in 5 meetings.  Strong employment growth, coupled with continued high trend inflation, suggest that there will be more.  My guess is that we will start hearing hints of that from policymakers any day now.
