Iran has been shipping oil through Turkey for years regardless of the sanctions, so I would not expect a huge increase in production. Iran will get a higher price without sanctions for the oil that was being slipped out of the country through Turkey. One question that will impact crude oil prices the most is stability in the Middle East. I'd give Iran 6-10 years to have a nuclear weapon. They are smart and well educated people, and they will get the nuclear devices just like North Korea got their nukes when Clinton made a deal with them that was suppose to prevent them from getting Nukes. At some point Saudi will be compromised, and safe passage of oil out of the region will cause prices to increase. If we have to resort to higher priced unconventional shale oil from the US, expect prices to go up. Regardless, it will be interesting to see how this plays out. Regards.
