Price of gasoline does not seem to correlate with demand.
Looking at the adjacent graph we might conclude that the price of gasoline in the US has little correlation with the demand. In fact either on May 2003 and again late 2015 when the price of gasoline bottomed in the US, the consumption of gasoline either stayed the same or was lowered by a little. Additionally in the run from 2001 to 2008 –when the price topped at $4 per gallon the consumption increased from about 9000 bpd to 9500 bpd. On the summit of Sept 2008 the priced plummeted to $1.75. Now in the early 2016, the retail price is at $2.00 but the NYMEX Futures are at $1.15 and the demand maintained a is on a positive. There is little evidence that demand is slowing in the USA; there is also little evidence that the world demand is significantly lower.
