Dollar Dominance Unravels: Petrodollar System Eroding Under Five Structural Forces

The dollar's dominance as the global reserve currency has been eroding for decades. It didn't become the world's reserve currency through military conquest or legal mandate, but rather due to a single diplomatic arrangement in 1974 that created self-reinforcing demand for the currency.

This mechanism was built on oil. The 1973 OPEC embargo quadrupled energy prices almost overnight, flooding Gulf states with dollar surpluses their domestic economies couldn't absorb. In June 1974, the US and Saudi Arabia formalized a broad cooperation framework covering military and economic dimensions. The following month, Treasury Secretary William Simon traveled to Jeddah to lock in the financial architecture: Saudi Arabia would price and settle oil sales in US dollars and recycle surpluses into US Treasury bonds; the United States would provide military protection and economic partnership.

This was never a single treaty. It was a layered set of diplomatic understandings, which is precisely why its unwinding is equally informal and gradual.
