Energy Prices: Gasoline High, Natural Gas Takes Surprising Jump, Too
by Carol Stone August 26, 2005

Perhaps it's not necessary to document energy prices so, ah, graphically. But their changes have been dramatic, and the reaction of the University of Michigan Consumer Sentiment survey (see above) is probably just the first obvious sign of their impact in a piece of economic data. "Employee discount" pricing by several major auto manufacturers is another response, as those firms seek to clear stocks particularly of larger, less gas- efficient models.

Gasoline demand has been strong. In our second graph, we show Department of Energy data on weekly gasoline consumption; this is contained in Haver's OILWKLY database, compiled and provided to us by the "Oil & Gas Journal". In this DLXVG3 graph, we've used the lead-lag feature to shift the series back one year so as to compare weekly seasonal patterns. Earlier years saw a clear spike in gasoline consumption at about this time of the summer, a sharp rise followed by just as rapid a drop in early September. But 2004 was an exception, as you can see from different shape of the lagged curve compared with the "normal" development in 2003; consumption rose earlier in the season and stayed high all summer long before spiking and then dropping back in the autumn. But, over the winter, demand didn't fall as much as it had previously. This year, starting from a higher base, spring demand gained and has since sustained still higher volume over many weeks -- despite the surging cost.

Another non-traditional development this summer has been an extraordinary rise in natural gas prices. Called to our attention by an ordinary news article in the Wall Street Journal, the recent surge in those prices is unprecedented. While some summers have seen a slight rise in August, previous experiences like this year's sharp price increase have only come in the winter, when heating demand is great. The Journal attributed this to a "hot summer" eliciting more electricity output from gas-fired power plants. Our casual examination of recent temperature patterns suggests that through July, this summer has not been especially hot, and this theory seems to bear more investigation.

The recent sizable energy price advances look likely to cause consumers and businesses to alter their budgetary priorities, and as we noted at the outset, the drop in consumer sentiment may be an early concrete signal that consumers realize they will have to implement such changes.
