The catalyst that moved oil prices higher over the past two days, and which had overriden the "bad news" from the Doha talks failure, was the Kuwait oil workers strike announced over the weekend and which resulted in up to 1.6mmb/d in production being taken offline. As of moments ago, however, according to Kuwait's Aljarida press website, the strike is now over.
