Democratic and Republican senators urged U.S. President Joe Biden's administration on Tuesday to impose secondary sanctions on international banks to strengthen a price cap G7 countries plan to impose on Russian oil over Moscow's invasion of Ukraine.

Democratic Senator Chris Van Hollen and Republican Senator Pat Toomey introduced legislation imposing the secondary sanctions, which would target financial institutions involved in trade finance, insurance, reinsurance and brokerage of Russia oil and petroleum products sold at prices exceeding the cap.

The two senators are both members of the Senate Banking Committee, which oversees sanctions policy.

They said the ability to target banks would make it harder for Russia to evade the price cap by making deals with countries not formally participating in the G7 scheme.

"I do think there's a great benefit to having a worldwide backup so that Russia does not try - as it's bound to do - to play countries against each other," van Hollen said during a committee hearing.

"I promise to work with Senator Van Hollen to get this bill enacted as soon as possible so that Russia can no longer profit from the oil sales funding its war in Ukraine," Toomey, the top Republican on the banking panel, said.

The Biden administration has been reluctant to impose secondary sanctions over concerns that they could complicate relations with importers of Russia oil like China and India.

Elizabeth Rosenberg, Treasury Assistant Secretary for Terrorist Financing and Financial Crimes, told the hearing that the price cap was a powerful tool to hit Russia and stabilize energy prices.

The U.S. Treasury has said that anyone who falsifies documentation or otherwise hides the true origin or price of Russian oil would face consequences under the domestic law of jurisdictions implementing the price cap.

The Group of Seven announced the price cap plan this month to limit Russia's lucrative oil export revenue in the wake of the invasion. Several countries have banned imports of Russian crude and fuel, but Moscow has managed to maintain its revenues through increased crude sales to Asia.

"The price cap we believe will have a powerful effect in doing several things, certainly in the first instance denying Russia's revenue to fund its war," Rosenberg said. "And secondly, by keeping Russian oil in the market at lower prices, it will reduce the potential for price spikes in the market."

Also at the hearing, Democratic Senator Kyrsten Sinema asked Rosenberg what Washington can do to address the blending of Russian oil by the country's producers with crude from other nations to circumvent sanctions.

Rosenberg indicated that Treasury will in coming weeks release guidelines to address the issue.

"We have an opportunity to offer further clarity and guidance on this important point in the forthcoming guidance and frequently asked questions that the U.S. government will put out in the coming weeks," she said.
