America’s aggressive use of sanctions endangers the dollar’s reign

EVER SINCE the dollar cemented its role as the world’s dominant currency in the 1950s, it has been clear that America’s position as the sole financial superpower gives it extraordinary influence over other countries’ economic destinies. But it is only under President Donald Trump that America has used its powers routinely and to their full extent, by engaging in financial warfare. The results have been awe-inspiring and shocking. They have in turn prompted other countries to seek to break free of American financial hegemony.

In 2018 America’s Treasury put legal measures in place that prevented Rusal, a strategically important Russian aluminium firm, from freely accessing the dollar-based financial system—with devastating effect. Overnight it was unable to deal with many counterparties. Western clearing houses refused to settle its debt securities. The price of its bonds collapsed (the restrictions were later lifted). America now has over 30 active financial- and trade-sanctions programmes. On January 10th it announced measures that the treasury secretary, Steven Mnuchin, said would “cut off billions of dollars of support to the Iranian regime”. The State Department, meanwhile, said that Iraq could lose access to its government account at the Federal Reserve Bank of New York. That would restrict Iraq’s use of oil revenues, causing a cash crunch and flattening its economy.
