Goldman Sachs on oil prices and the OPEC meeting:
Intraday oil price volatility has picked up over the past week and ahead of today’s OPEC advisory meeting in Algiers. Statements by participants suggest a deal to curb production today or at the next meeting in November is more likely than at any point over the past two years.  independent of today’s outcome, our production forecast continues to reflect a seasonal Saudi production decline into year-end and no growth elsewhere, the equivalent of a deal; andeven with this OPEC help, our updated oil supply-demand forecast now points to a renewed build in inventories in 4Q 2016 vs. a forecast for a draw only last month.
