Remember the 80's, when the price decreased. Revenues dropped so they pumped more to make up for it, which put further downward pressure on prices. During the first Reagan administration oil dropped to $10 a barrel, fueling a big bull market in the west.
If the forecasts of a recession are correct, then demand will decrease and prices will fall. What of the big construction projects like those islands in Dubai? Those guys need money, and they will pump until they get it.
The share of global production represented by OPEC is falling steadily. Their power is decreasing annually. Moreover, once times get just slightly difficult for them, we see the falling-out as countries set their own quotas for their own reasons.
It's a problem. The more it costs the greater is the incentive in the west to use less. The lower the price the greater is the risk to their domestic economies.
