The Consumer Price Index (CPI) decreased by 1.4 percent, before seasonal adjustment, during the 12 months ending in June, according to data released this month by the Bureau of Labor Statistics. The 12-month rate of price change was also negative in March, April, and May - and the rate of decrease has accelerated each month. The major factor is the sharp decrease in energy prices compared to their level a year ago. Even though energy prices rose more than 7 percent in June, they were still 25 percent below their level in June 2008.

Rate of Price Inflation

The general level of prices has not trended downward this long, and this much, since 1950. As shown in the chart above, price inflation, not deflation, has been the norm in the post-WWII years.

Even moderate rates of price inflation, if they persist, can greatly erode the purchasing power of the dollar over time. Over the past 10 years, the annual rate of price inflation averaged 2.6 percent, which sounds relatively low. The cumulative result, however, is that the general price level rose by 29.8 percent. To buy what a dollar bought in 1999, the average consumer now needs $1.30.

The increase in the average price level masks wide variation in the price changes for specific items. The table below shows a breakdown of price changes over the past year and the past 10 years, by major categories of goods and services.

those prices you see for a barrel of oil, if i remember correctly, are spot market prices. Not the long term low price contracts that the oil companies arte locked into.
Overall CPI meaningless

Transportation, energy, and "other goods and services" are far beyond the norm and should be excluded. Doing so suggests the Real CPI is around 2.0 or slightly more.

COMPARING THE PRICE OF GAS TODAY VS A YEAR AGO IS NOT AN ACCURATE REFLECTION OF GASOLINE/OIL PRICES.

A YEAR AGO THE PRICE OF A BARREL OF OIL WAS CLOSE TO $150.00 TO BE EXACT IT HIT A HIGH OF 147.00 A BARREL. AT THAT POINT GAS SOLD FOR $4.50 A GALLON. TODAY OIL IS AROUND $60.00 A BARREL AND THE PRICE OF GAS WAS OVER $3.00...BASED ON THE CURRENT CALCULATIONS IF OIL EVERY REACHEAS $147.00 A BARREL THE PRICE OF GAS WILL BE IN THE $6.50 TO $7.00 PER GALLON RANGE.

IN MY VIEW IT APPEARS THAT SOMEONE (OIL COMPANIES) HAVE COME UP WITH A NEW EQUATION FOR PRICING OIL PRICES VS GASOLINE PRICES....

NO DOUBT THIS WILL BE A SURPRISE TO MANY.....YEAH SURE MIKE!

You should use a semi-log scale to give a more accurate picture of what's happening.
