Eurodollars are dollar-denominated bank deposits held at foreign banks or overseas branches of U.S. banks. They are essentially offshore dollars that sit outside the U.S. banking system and Federal Reserve control. With nearly $10 trillion outstanding, they form the backbone of the global dollar system, enabling non-U.S. banks to hold and lend dollars internationally.
The Soviet Union withdrew its gold and dollar reserves from New York in 1947 due to fears of potential U.S. sanctions, inspired by the U.S. freezing Yugoslavia’s gold reserves earlier. The Soviets moved their assets to Paris, where they stored them in banks like Bicen, a communist-sympathizing bank, to ensure access to dollars and gold outside U.S. control.
The eurodollar market began in the late 1940s as a way for communist countries like the Soviet Union and China to evade potential U.S. sanctions. They deposited dollars in European banks, such as Bicen in Paris, which issued dollar liabilities. These deposits were used to finance East-West trade and later expanded into a broader market for dollar-denominated banking outside the U.S.
London became a central hub for the eurodollar market in the 1950s, as British banks like Midland Bank began issuing eurodollars to facilitate cross-border interest rate arbitrage. The liberalization of the foreign exchange forward market in 1952 allowed these banks to hedge dollar risk, making eurodollars a profitable and attractive financial instrument for international trade and finance.
The U.S. Federal Reserve viewed the eurodollar market as useful because it increased the global appeal and utility of the U.S. dollar. By allowing central banks and corporations to hold dollar balances offshore, the market kept dollars circulating internationally without touching the U.S. financial system, thereby enhancing the dollar's role in global trade and finance.
The eurodollar market emerged as a solution to the U.S. balance of payments crisis under the Bretton Woods system. As the U.S. faced a growing mismatch between its gold reserves and dollar liabilities, the eurodollar market provided a way to keep dollars circulating offshore, reducing pressure on the U.S. to redeem dollars for gold and helping sustain the global dollar system.
The eurodollar market evolved from its communist origins in the late 1940s, where it was used for sanctions evasion and financing East-West trade, into a global financial system in the 1950s and 1960s. London banks adopted the practice, using eurodollars for cross-border arbitrage and trade financing. By the 1960s, U.S., Japanese, and European banks had established branches in London, turning eurodollars into a cornerstone of international finance.
At more than $10 trillion outstanding, the eurodollar market is one of the biggest forms of shadow banking activity out there. It's also one of the most interesting markets in existence, allowing non-US banks to hold and lend offshore dollars that effectively sit outside of the Federal Reserve's control. But where did eurodollars actually come from? Why did the US allow these "shadow dollars" to exist at all? And what do eurodollars mean for the greenback's role in the global financial system? In this special three-part series, we look back at the hidden history of the eurodollar market. The story is told by Columbia Law School Professor Lev Menand and Federal Reserve Bank of New York Policy Advisor Josh Younger. We start in the aftermath of World War II, when Europe is in the midst of an expensive reconstruction and the world is in the early throes of the Cold War. It's here that the eurodollar is born.
