In what appears to be a bid to lure Asian buyers to lock in longer-term supplies, Reuters reports that Iran has cut its quarterly selling price (for its flagship 'light' crude) to its lowest (relative to Saudi) since Q4 2012. According to recent tanker loading data, Iran's oil sales in September are set to hit a six-month low, and this price reduction is just one of the steps taken by the OPEC producer to ramp up output and regain market share lost since U.S. and European sanctions aimed at its nuclear program cut its crude oil exports by more than half.
