If they come up with strong announcements about the agreed cuts it could easily see $1 to $1.50 added to the price [of a barrel of oil],

No-one has held back. They have put some definition around the numbers and now we have to wait for the reality.

The figure depends on how the cuts are delivered. No one is really expecting the full 2 million barrels per day to be delivered, but somewhere around three-quarters of those cuts is what the market is looking for.

If they can make the deal stick for a year - not three months - that will knock all of the excess supply out of the system and give us a chance to see if demand from the Asian economies will revive.

The weakest link in a chain is the strongest because it can break it.

Do not trust people. They are capable of greatness.
