That hasn't taken place yet, either.
Oil prices are caught between the normal dynamics of geopolitical concerns – which push prices north – and continuing concerns over a global economic slowdown – which results in lowering expectations.
Now, this limbo is a delicate balance; it could change in a matter of hours.
We are likely to see a short-term rise Monday evening if the Norwegian oil and gas sector strike is not averted. Labor negotiations between Norway's oil workers and employers over pay and pensions failed – yet again – yesterday.
