2313 GMT - CBA now estimates that global oil markets have 5 to 10 weeks before oil and refined product inventories deplete. That compares with estimates of closer to 15 to 20 weeks just two weeks ago. Inventory depletion raises the risk that Brent oil futures rise to $US150 per barrel, it adds. The leverage that Iran and their proxies have exerted via their control of key straits and their attack on Saudi Arabia's pipeline infrastructure has caused oil and refined product prices to surge and condensed the timeline for inventory depletion, says Vivek Dhar, economist at CBA. Dhar is now more confident that the U.S. will seek to make a deal with Iran.
