This is my “worksheet” that gives an estimate of gasoline’s impact on inflation. The top panel is the monthly average of gasoline pries, calculated from the daily updates above. Last month (February), gasoline prices averaged $2.93. The March monthly average is now $3.47. But see the chart above, the last (March 16) reading was $3.79. So, this average will keep going up.
The second panel shows how much gasoline prices have changed. This is the average from February to March average to date. Gasoline prices are up 18.28% to date. Again, the last reading (March 16) is about 30 cents higher, so this will continue to go up.
The third panel is Gasoline’s weight in CPI. It is currently 2.81%.
The fourth panel is gasoline’s impact on the monthly CPI. It is simply multiplying its monthly change (second panel) by its weight (third panel). It is suggested that gasoline ALONE will add 0.5% to CPI.
The fifth (bottom) panel shows the latest monthly readings. If gasoline is push on March CPI 0.5%, I assume everything else will add 0.2%, for a 0.7% March CPI (which again updates higher everyday). This will be the highest monthly reading since June 1.3% June 2022 (which is one of the highest readings ever).
