A Bloomberg survey showed OPEC crude output fell by 1.22 mln b/d in May to 16.33 mln b/d, the lowest in at least 37 years, with roughly half the decline coming from Iran. Iran's production dropped 710k b/d to 2.34 mln b/d, a five-year low, as CENTCOM continues to enforce a maritime blockade on all traffic to and from Iranian ports; Persian Gulf unrest also weighed on output. Data exclude the UAE, which left OPEC last month.
