KEY POINTS
  • U.S. sanctions on Iran, the third-largest producer in the Organization of the Petroleum Exporting Countries, kick in on Nov. 4.
  • Saudi Arabia is expected to add extra oil to the market over the next couple of months to offset the drop in Iranian production.
  • However, ANZ said in a note that major suppliers were unlikely to offset losses due to the sanctions estimated at 1.5 million bpd.

Oil prices rose more than 1 percent on Friday, with Brent climbing to a fresh four-year high, as U.S. sanctions on Tehran squeezed Iranian crude exports, tightening supply even as other key exporters increased production.

Brent crude futures rose $1, or 1.2 percent, at $82.72 a barrel by 2:28 p.m. ET. The session high of $82.87 was its highest since Nov. 10, 2014. In the third quarter, Brent has so far gained about 4 percent.
