Experts see substantial but moderate effects of tight oil on global politics.

摘要

According to Daniel Yergin of IHS CERA, Carlos Pasqual of the US State Department, and Luis Guisti of the Center for Strategic & International Studies, the US tight oil boom is having and will continue to have a major effect on international politics, though the impact will be less explosive than has sometimes been suggested. All three experts, speaking at a recent Bipartisan Policy Center conference, agreed that tight oil has increased Wasliington's influence over the geopolitical landscape, noting that the increased domestic production has allowed US sanctions to discourage purchases of Iranian crude without causing shortages. "Countries understand the need to restrain Iran's nuclear ambitions. They're likelier to do something about it if they're confident they can buy the oil elsewhere," said Pasqual.
