Economic sanctions remain one of the most powerful tools the United States has in its foreign policy arsenal. And as Russian forces continue to amass along the border with Ukraine, officials in the U.S. hope the threat of those sanctions can deter a full-scale invasion.

Besides sanctions that target individuals or specific companies, some proposals involve cutting Russia off from the SWIFT system, which would remove Russian institutions from an important global financial network.

Another target is the near-completed Nord Stream 2 gas pipeline, which when operational would double the amount of natural gas moved from Russia to Germany through the Baltic Sea and likely reduce the need for other pipelines, such as the Urengoy–Pomary–Uzhhorod pipeline that runs through Ukraine.

Republican Sen. Ted Cruz of Texas has proposed a bill that would require automatic sanctions against Nord Stream 2 operators within two weeks of Russia invading Ukraine. The bill failed to pass on Thursday, but picked up a handful of Democratic votes in the final tally.

Democratic Sens. Robert Menendez, of New Jersey, and Jeanne Shaheen, of New Hampshire, proposed an alternative bill that would “impose crippling sanctions on the Russian banking sector and senior military and government officials if President [Vladimir] Putin escalates hostile action in or against Ukraine.”
