Prices should fall to around $30 once the empty nature of an OPEC-plus-Russia production freeze is understood. A return to the grim reality of over-supply and the weakness of the world economy could push prices well into the $20s.

An OPEC-plus-Russia production cut would be a great step toward re-establishing oil-market balance. I believe that will happen later in 2016 but is not on the table today.

In late February, Saudi oil minister Ali Al-Naimi stated categorically, "There is no sense in wasting our time in seeking production cuts. That will not happen."

Instead, Russia and Saudi Arabia have apparently agreed to a production freeze. This is meaningless theater but it helped lift oil prices 37 percent from just more than $26 in mid-February to almost $36 per barrel last week.
