Business & Finance

Ironically, the US itself can weaken the world role of the dollar by unrestrained budget deficits (although the mechanism is uncertain) and certainly by overusing economic sanctions as a form of warfare. Sanctions involve ending a country’s direct links with the US economy, and indirectly by limiting its use of the dollar. We can cut off its use of US financial institutions and urge foreign banks to do the same by threatening their access to US financial facilities. Our weakening of the Iranian economy indicates that economic sanctions can be quite effective. The natural way for a sanctioned country to respond is to seek other currencies with which to do business and use financial institutions without links to the US. If the US does a lot of this, a critical mass of “sanctioned” countries might find a common new currency for their international transactions. The Chinese Remindbi comes to mind. The dollar’s world role would be greatly reduced. [Lawrence Krause, PhD]
