Sanctions against Iran have prompted discussion, and investment, in an alternative technology that would not be under US jurisdiction (1). The idea caught on with Russia replacing SWIFT for a majority of their market transactions (2). The EU joined as well (3), causing the US to reprimand them for not joining the confrontation (4) and threatening them with fines (5).
The Iran sanctions might go down in history as one of the most laughable attempts to economically isolate a nation. Not only was the directive generally ignored, it even managed to launch new technologies that directly undermined the US’s place as the central hub of the trillions of dollars of financial transactions that take place on a daily basis. Backed by the BRICS countries, it is likely there will be a second global standard before long (6).
