Why is oil priced in dollars?
A common currency makes a global, financialised commodity easier to compare, finance and hedge.
The intuitive answer
Because oil exporters are required to accept dollars.
The short answer
Oil is usually quoted and traded in dollars because the dollar is already the common currency of global trade and finance. Dollar funding, benchmarks, derivatives and liquid assets reinforce that choice. It is a durable convention, not a universal legal rule.
The unseen lever
Currency network effects connect the oil invoice to the deeper system used to finance cargoes, hedge prices, settle trade and store the proceeds.
