US dollar system

The US dollar system refers to the global financial infrastructure where transactions are predominantly conducted in US dollars, granting the United States significant leverage. This system is currently newsworthy due to its use as a tool for imposing sanctions. Recent developments show the US threatening to cut off access to the US dollar system for companies and airlines servicing Iran. This threat, articulated by Treasury Secretary Scott Bessent, aims to isolate Iran economically by penalizing third-party entities that maintain economic ties with the country. The US is prepared to impose severe sanctions on nations and entities, including potentially China, Iran's largest trading partner, if they resist US economic pressure. The current relevance lies in the US's willingness to wield its financial dominance to achieve foreign policy objectives, impacting international trade and the operational capacity of businesses worldwide that rely on dollar-denominated transactions.
