The Federal Reserve Act of 1913 created the infrastructure for the modern American payments system. Probing the origins of this benchmark legislation, the author of this study finds that international factors were crucial to its conception and passage. Until its passage, the USA had suffered under one of the most inefficient payment systems in the world. Serious banking panics erupted frequently and nominal interest rates fluctuated wildly. Structural and regulatory flaws contributed not only to financial instability at home but also to the virtual absence of the dollar in world trade and payments. Key institutional features of the Federal Reserve Act addressed both these shortcomings, but it was the goal of internationalizing usage of the dollar which motivated social actors to pressure Congress for the improvements. With New York bankers in the forefront, an international coalition lobbied for a system which would reduce internal problems such as recurring panics and simultaneously allow New York to challenge London's pre-eminence as the global banking centre and encourage bankers to make the dollar a worldwide currency of record. To those who organized the political effort to pass the Act, Broz contends, the creation of the Federal Reserve System was first and foremost a response to international opportunities.
