Asha will do her usual excellent job of synthesizing the February retail sales
report and highlighting the important implications of it. But I wanted to call
your attention to an interesting trend change in retail sales. As shown in
the chart below, the trend in nominal retail sales is down. The year-over-year
change in the 3-month moving average of nominal retail sales was 3.69% in February
(read off the left-hand scale), down from its peak growth of 9.25% in August
2005 and the slowest growth since June 2003. Why the pronounced downward trend
in the growth of nominal retail sales? Well, perhaps because of the downward
trend in overall consumer inflation, largely as a result of the decline in
oil prices from their 2006 peak of $75 a barrel. But why would the decline
in oil prices be associated with a decline in the growth of nominal retail
sales? Won't folks spend their gas pump savings at the mall, thus maintaining
the growth in nominal retail sales? Perhaps some folks are starting to develop
anxiety about their finances and are depositing their gas pump savings into
a savings account at a bank? Whatever the reason for the current sharp slowing
in the trend of nominal retail sales growth, past such sharp slowing trends
have typically been associated with declines in the federal funds rate - presumably
purposely engineered by the Fed - and/or recessions. But it's probably just
the weather this time.
