What is Prime Brokerage?

The Ultimate Guide To Prime Brokerages

Traders realize they need a broker to execute trades. Whether its direct access or conventional zero-commission app-based trading, a brokerage (registered broker-dealer) is required to execute trades. A prime brokerage goes beyond just execution but provides a suite of services that enable large institutions, traders, hedge funds to implement their trading strategies at a cost. Prime brokers typically don’t provide execution of trades but often times will have inhouse execution services within the same institution.

What is a Prime Brokerage?

A prime brokerage is a large institution typically used by hedge funds, family offices and large traders to help execute and finance their trading or portfolio strategy. Consider a prime brokerage like a primary care physician that provides most of your medical treatment. An executing broker is like a specialist. Primary care physicians may refer you to a specialist that is also housed under the same umbrella under the medical group. 

Don’t expect zero-commissions as the services they provide are laden with fees. Prime brokers are typically reserved for hedge funds to help finance their strategy as well as introduce them to capital. The term prime brokerage can be misleading as they technically not an executing broker, but serve almost like a partner providing custodial, clearing, and financing services. Most prime brokerages are partnered with executing brokers or have them inhouse within the same umbrella of the institution as the trading division. 

What Does a Prime Brokerage Do?

Not to be confused with a typical execution broker, a prime broker is a large institution that provides various custodial and financial services to its clients including financing transactions and positions, cash, margin and stock lending, consulting, and capital introduction.

Prime Brokerage

Prime brokerage services are provided by some of largest investment banks in the world like Goldman Sachs, JPMorgan Chase, Morgan Stanley and so forth. They are responsible for providing a plethora of services to bolster leverage and assist in optimize trading strategies. While they are considered primary counterparties to its clients, but they don’t trade against them or take the other side. They may step into a position on behalf of the client directly or synthetically but have no upside if the trade goes sour against the client, in general. 

Who Needs a Prime Brokerage?

Who is eligible?

Each prime brokerage has its own requirements to become a client. Keep in mind that a prime brokerage makes its money from fees, interest on loans (cash, margin, and securities), and commissions. Based on this, the larger your assets under management (AUM), transactions, and compelling your strategies are the more attractive you are as a client. It can range from as low as $500,000 to $40 million to $50 million in assets. It depends on the individual prime broker.

Most prime brokers seek to service hedge funds, institutions like pension funds, and commercial banks. While established hedge funds are a prime target client, there is always the hope for new hedge funds with rising stars that may grow into a big client. This is one way smaller funds can benefit from a prime brokerage.

Who will benefit from it?

Hedge funds benefit greatly from prime brokers. Since they are more active with trading and tend to generate more commissions and fees, prime brokers also prefer these active participants. The competition between hedge funds to grow AUM is a constant. Prime brokers have a critical part in providing introduction to new capital for hedge funds. Hedge funds also benefit from the core service offerings on up to the more concierge style additional services that are provided to the larger clients.
