It makes sense the gas price to rise when oil price rises and to drop when oil price drops. But, it looks like people do not want to understand that the gas price increase / decrease cannot be directly proportional to the oil price increase / decrease.
Oil price has now dropped below 50 USD a barrel from a 147 USD high (almost three times). There are people who are asking why the gas price hasn’t drop three times and complain about it. They tend to forget that, when the oil price rose, the gas price did not rose proportionally. At that time, they complained about the gas price rise, but they did not think it might get worst.
On the other side, the gas vendors are not fair either. Let’s suppose that, at some moment in the past, the gas price was X and the oil price was Y. During a period of time the oil price moved to Y + y; for this reason, the gas price moved to X + x (as mentioned, we have y / Y > x / X). When the oil price dropped back to Y, the gas price only dropped to X + xx (xx < x, but xx > 0). Therefore, even if the oil price is now the same as it was some time in the past, we now pay for gas a little bit more than we payed at that time.
The conclusion is, that oil and gas prices do not move in sync, but when oil price rises, gas price quickly rises too and when oil price drops, gas price does not drop as quickly as they rose
We should not expect that, if the oil price returns to a certain level, the gas price will also return to the same level. Fair? I do not think so! To be expected? Certainly!
