STEVE INSKEEP, HOST:
Now, as Americans talk of exporting natural gas, they're also looking to block energy exports from Iran. The U.S. and Europe are intensifying sanctions, pressing Iran over its nuclear program. The latest sanctions would raise many barriers to Iranian oil exports. But the global economy is interconnected, so the challenge is cutting off Iran's oil without harming the rest of the world. NPR's Tom Gjelten reports that some advocates of sanctions have actually devised complex models to show how to do that.
TOM GJELTEN, BYLINE: A problem with sanctions is they don't always work as intended. If, for example, the U.S. and Europe don't buy Iran's oil, but other countries pick up the slack, nothing is accomplished. Or if some Iranian oil is taken off the market but the price goes up, Iran could earn just as much from its oil, even though it's selling less. Mark Dubowitz runs the Iran Energy Project at the Foundation for the Defense of Democracies. His organization supports the Iran sanctions and has an international team of researchers, mathematicians, and economists working to show how the sanctions can do exactly what they're meant to do.
MARK DUBOWITZ: We've identified Iran's major oil purchases, how much they're buying, thousands of barrels a day. We look at how much oil revenue each country is contributing to Iran and then we run scenarios, you know, based on a certain change in output.
GJELTEN: Dubowitz and his team are assuming that over the next six months, as the sanctions take effect, the European Union countries will cut their purchase of Iranian oil by 80 percent. Not 100 percent - some will still leak through. They also assume India, Japan and Korea will cut back their oil purchases from Iran. Is that realistic? Those three countries are big consumers of Iranian oil. India's foreign minister says his country will not abide by the U.S. and EU sanctions. But Dubowitz and his team say it's more important to look at what Indian refinery operators do on their own. Especially since U.S. sanctions would punish foreign companies that buy Iran's oil.
DUBOWITZ: A number of the refiners have significant U.S. interests and assets, and we believe that a number of Indian refineries are going to make an independent decision to comply with U.S. sanctions because they don't want to risk getting sanctioned and cut off from the U.S. market.
GJELTEN: So that's India. As for Japan and South Korea, Dubowitz thinks those governments will want to protect their companies from U.S. sanctions.
DUBOWITZ: They do not want to get in a fight with Congress during election season on this issue. They are absolutely paranoid about the prospects of Japanese and South Korean companies ending up on somebody's name and shame list.
GJELTEN: To be spared that embarrassment, Japan and South Korea are likely to reduce their Iranian oil imports by 15 percent, according to this model - enough to show they're at least making an effort. So from Europe to Asia, those are where the cuts occur. China, on the other hand, is projected to increase its purchase of Iranian oil. In all, by this team's calculation, Iran will see a net loss of about 500,000 barrels each day due to sanctions. And that alone would cost Iran money, but in addition, Iran might be hurt another way. With other countries cutting back on their imports, the countries that buy more oil - notably China - could insist that Iran sell to them below market price. In this case, Dubowitz and his team predict China will be able to negotiate about a 15 percent discount.
DUBOWITZ: We actually assess that if there were no other buyers of Iranian oil, China could actually negotiate a 40 percent discount. Now, of course, there are going to be other buyers of Iranian oil so the Chinese are not going to have absolute negotiating leverage. Fifteen percent puts it at actually a pretty reasonable end of the range.
GJELTEN: Between the loss of some exports and the need to accept a lower price, Iran under this model could lose $20 billion a year - quite a blow for an already weak economy. We ran these projections by some global energy consultants. In general, they agreed Iranian oil exports are likely to decrease, though perhaps not as much as Mark Dubowitz's Iran Energy Project is predicting. The other consultants also foresaw limited damage to the global economy. Whether the Iranians will be forced to offer steep discounts on their oil, however, is not so clear. Jamie Webster is a Middle East oil analyst at PFC Energy.
JAMIE WEBSTER: We don't see a huge discounting occur. Now, that - the amount that we've seen in the past of a dollar or so, a couple dollars, that may rise, but I still don't see it as being, you know, a huge amount that it's going to impact their revenues significantly enough to really put them in a bad spot.
GJELTEN: Of course, even if Iran is put in a bad spot, whether that would be enough to drive its leaders to the nuclear negotiating table is another question entirely. Tom Gjelten, NPR News, Washington.
