Prime brokerage is a bundle of specialized financial services that investment banks provide to hedge funds and other large institutional clients.
Mechanics of prime brokerage
For Elephants managing large pools of capital, a prime broker provides the infrastructure necessary to execute complex investment strategies. When a hedge fund needs to execute large block trades, secure leverage, manage daily cash balances, or borrow securities for short selling, the prime broker handles these operations. The prime broker centralizes the clearing and settlement of trades across various global exchanges.
A major component of prime brokerage is financing. Prime brokers lend cash to hedge funds so the funds can purchase assets on margin. Prime brokers also locate and lend stocks or bonds that the hedge fund wishes to short sell. The investment bank earns revenue from this relationship through multiple channels. These revenue streams include fees on trade execution, interest on margin loans, spreads on stock loans, and administrative fees for custody services.
Hedge funds use prime brokers to consolidate their reporting and risk management. By holding assets and executing trades through a single entity or a small group of prime brokers, the hedge fund simplifies its operational workflow. Prime brokerage operates globally, with major hubs in London, New York, Tokyo, and Hong Kong. Local regulations dictate how prime brokers operate in different countries. Jurisdictions apply different rules regarding margin requirements, capital limits, and the rehypothecation of client assets.
Example
Suppose an Elephant running a global macro hedge fund, Trunk Capital, decides to short sell shares of a large agricultural corporation. Trunk Capital does not currently own these shares. The fund contacts its prime broker to initiate the position. The prime broker locates the necessary shares in the custody account of a different institutional client and lends them to Trunk Capital. Trunk Capital sells the borrowed shares on the open market, and the prime broker processes the settlement of the trade. If the stock price falls, Trunk Capital buys the shares back at the lower price and returns them to the prime broker. The prime broker charges Trunk Capital a fee for the stock loan and a commission for trade execution.
