WASHINGTON – The United States and Europe are considering unprecedented punishment against Iran that could immediately cripple the country's financial lifeline. But it's an extreme option in the banking world that would come with its own costs.
The Obama administration wants Iran evicted from SWIFT, an independent financial clearinghouse that is crucial to the country's overseas oil sales. That would leapfrog the current slow-pressure campaign of sanctions aimed at persuading Iran to drop what the U.S. and its allies contend is a drive toward developing and building nuclear weapons. It also perhaps would buy time for the U.S. to persuade Israel not to launch a pre-emptive military strike on Iran this spring.
