the thing about being right 6 out of 6 times, is what happens when you miss calling the 7th.
by the above graph, it looks like crude spiked about 10 years before the recession of 1929, so how's that fit into your theory? the 1953 recession? oil peaked about 4-5 years before that. let's see, the recession of 1957? nope, no spike there either. the recession of 1960 perhaps? not only wasn't oil peaking, it was already on the downslide. the oil crisis recession of 1973, ooops, the peak came after the fact. would have been tough to judge that without a time machine.
My point was to note when oil doubled (oil shock / crisis) in price during the course of a year, regardless of when the peak occurred... recession is directly associated and did follow. For a list of recessions and when they occurred, please refer to Wikipedia or official sources.
In the graph I presented, which reflects in shaded bars when the recession occurred, which reflects the peak in the price of oil, the recession occurred concurrent with or after the peak. It does so in an accurate, adequate and simply way.
To correct you:
1. The price of energy was not a good way to measure the onset of recession prior to the 60's, because our economy was not dependent upon foreign oil. We began importing in earnest during the 60's.
2. The graph that you presented shows odd years along the bottom with no grid, and no reference to recession as it would lay over the the price of oil. Looking at the graph you presented, one would not be able to see the cause and effect. The graph you presented is insufficient and lacking.
3. Oil peaked in 1973. The recession started in 1973 and ended in 1975. This was not an "ooops..." It looks like you read the graph you presented wrong.
There were other recessions not related to the price of energy. DUH.
For the average person, who can see the price of energy double in a short period of time, you can take steps to protect investment, because the economy does and will tank. Unless you are an insider, most people don't have a tried and true measure to go by. My observation provides those who do not have a clue that they can use to protect themselves in a real way.
Unless energy policy and politics change, and angels with trumpets and harps descend upon the Earth, you can rest assured the next time oil doubles in price (oil shock) in less than a year, a recession will follow.
