Instead, the event with the most long-term significance may be one that received little attention in the mainstream media — Saudi Arabia's movement toward accepting currencies other than the US dollar for oil payments.

After President Nixon severed the last link between the dollar and gold, his administration negotiated a deal with the Saudi government. The US would support the Saudi regime, including by providing weapons. In exchange, the Saudis would conduct all oil transactions in dollars. The Saudis also agreed to use surplus dollars they accumulated to purchase US Treasury bonds. The resulting "petrodollar" is a major reason why the dollar has maintained its world reserve currency status.

Also this year, China and Brazil made an agreement to conduct future trade between the countries using the countries' own currencies rather than dollars. Brazilian President Lula da Silva has called on more nations to abandon the dollar.
