What is Prime of Prime (PoP)?

Prime of Prime, or PoP, is a firm that provides a retail broker (often forex brokers) with access to the trading liquidity pool of the big banks. These big banks are tier one banks, and not just anyone can trade with them. The PoP has access to these big banks, sets up the retail broker with the access, and the retail broker can connect their smaller retail clients orders with the large orders of the tier one bank.

Key Takeaways

  • A Prime of Prime (PoP) broker is one that has an account with a tier one bank, and lets retail brokers trade through that account so the retail broker can access the tier one bank's liquidity.
  • Trading directly with a tier one bank and accessing its liquidity is difficult for individuals and small firms, so the PoP bridges the gap and provides the smaller player with access.
  • In order to attract business, PoP brokerages and their associated retail brokers typically offer higher leverage and smaller trade sizes than a prime broker.

Understanding Prime of Prime (PoP)

Tier one banks tend to be risk-averse, and therefore demand strict financial protocols and risk management from their clients. A retail broker may not meet these rigid standards and therefore may not be able to trade directly with the tier one bank. The PoP does meet the standards, is a client or partner with the tier one banks, and allows the retail broker to trade through them with the tier one bank.

Since the PoP already meets the standards the big banks are looking for, the retail broker using the PoP will typically offer higher leverage to its traders, and offer smaller trade sizes than what would be available if trading directly with a tier one bank. They do this to attract business.

One of the reasons that tier one banks and prime brokers don't provide the services that PoPs do is that there is a smaller profit margin in the smaller trades which typically come from a retail client and their broker. Additionally, their systems often don't support a cost-effective way to complete smaller trades. PoP brokerages are also equipped to deal with increasing regulatory requirements for highly leveraged trades.

Classifying Prime of Prime Brokers

PoPs are considered tier two brokerage firms. Tier one is the brokerage arm of large banks that allow institutional traders and customers to trade with the bank. Tier two, or PoP, can best be described as a brokerage firm that has an account with the tier one brokerage firm and allows its customers to trade with them. They are essentially bridging the gap between small retail investors and the large tier one firms.

However, most PoPs will not deal directly with individuals—the retail brokers do that. The retail broker handles individual clients and tries to attract more business.

Prime of Prime Brokers in Action

Clients will use a PoP service for a number of reasons. Firstly, it provides access to more liquidity, which is important for traders. Secondly, PoP gives traders access to products that standard prime brokerage accounts don't offer such as non-deliverable forwards (NDF). 

The PoP structure came under scrutiny in January 2015, when the Swiss National Bank (SNB) removed the franc peg against the euro, which saw its currency plummet over 30 percent. This led to many PoP accounts losing large sums of money because the amount of capital its clients had in their accounts did not cover the large losses.

This event saw PoPs lift the amount of funds needed in its customer's accounts for capital requirements, along with other risk management protocols being enforced.

Example of Prime of Prime Broker

Retail forex brokers are largely PoP in the sense that when they start out they are too small to deal directly with the big banks and access their liquidity. For this reason, they will seek out a PoP broker that will link them up with the big banks.

By linking to the big banks, the retail broker is able to get live price quotes from the major banks, which creates the quotes that their retail clients are able to trade and interact with. This would not be possible if the broker didn't link up with the tier one firms.

The retail broker may mark up the spread that they receive from the tier one banks. For example, the raw tier one spread on the EUR/USD may be 1.12565 by 1.12568, but the rate clients see is 1.12563 by 1.12570. This is one way forex brokers make their money. Other ways include charging a commission on each trade.

Typically, the more PoP accounts or links to the big banks a retail broker can get, the better. Liquidity from five big banks is much better than liquidity from only one. The more tier one banks providing the retail broker with quotes and volume, the lower the retail broker's spreads will be, all else being equal. This is why forex brokers advertise how much liquidity they have access to and which big banks are providing it.
