A primary dealer is a firm that buys government securities directly from a government, with the intention of reselling them to others, thus acting as a market maker of government securities. The government may regulate the behavior and number of its primary dealers and impose conditions of entry. Some governments sell their securities only to primary dealers; some sell them to others as well. Governments that use primary dealers include Belgium, Brazil, Canada, China, France, Hong Kong, India, Italy, Japan, Singapore, Spain, the United Kingdom, and the United States.
In the United States, a primary dealer is a bank or securities broker-dealer that is permitted to trade directly with the Federal Reserve System ("the Fed"). Such firms are required to make bids or offers when the Fed conducts open market operations, provide information to the Fed's open market trading desk, and to participate actively in U.S. Treasury securities auctions. They consult with both the U.S. Treasury and the Fed about funding the budget deficit and implementing monetary policy. Many former employees of primary dealers work at the Treasury because of their expertise in the government debt markets, though the Fed avoids a similar revolving door policy.
The relationship between the Fed and the primary dealers is governed by the Primary Dealers Act of 1988 and the Fed's operating policy "Administration of Relationships with Primary Dealers." Primary dealers purchase the vast majority of the U.S. Treasury securities (T-bills, T-notes, and T-bonds) sold at auction, and resell them to the public. Their activities extend well beyond the Treasury market. For example, according to the Wall Street Journal Europe (2/9/06 p. 20), all of the top ten dealers in the foreign exchange market are also primary dealers, and between them account for almost 73% of foreign exchange trading volume. Arguably, this group's members are the most influential and powerful non-governmental institutions in global financial markets. Group membership changes slowly, with the current list available from the New York Fed.
