The following table shows the top 15 broker-dealers based on their assets under management in 2018. These are the firms that play an important role in helping U.S. government-issued securities to be distributed from the primary brokers that contract directly with the Federal Reserve Bank all the way down the investment chain to small retail investors as well as larger, commercial purchasers. Whereas the very large brokers that trade directly with the Federal Reserve Bank are called “primary dealers,” these smaller firms are typically referred to as “secondary dealers.”
