Federal Reserve Chair Jerome Powell warned on Wednesday that there could be some effects on the United States economy related to Russia's ban from the SWIFT international payment system.
However, Powell noted that the strength of the possible effects is difficult to predict since the US and Russian economies don't have much interaction.
Powell also remarked that the US is benefiting from the dollar being the world's most-used reserve currency, adding it is possible to have more than one reserve currency if the global financial situation changes.
