Prime of Prime (PoP) in forex brokerage explained

Quick answer
A prime of prime, or PoP, is an intermediary that holds an account with a tier-1 prime broker and resells that liquidity in smaller credit lines to retail forex brokers, hedge funds, and proprietary firms that cannot meet the capital and balance sheet requirements demanded by the prime bank directly.
What is prime of prime?
Prime of prime describes a firm that sits between tier-1 prime brokers, typically large investment banks such as Goldman Sachs, JP Morgan, or UBS, and downstream clients who lack the balance sheet to open a direct prime brokerage account. After the 2008 crisis and subsequent regulatory tightening, prime brokers raised minimum funding requirements, often above twenty-five million dollars, pricing out smaller brokers. PoP firms hold one large prime account, then offer aggregated bank liquidity, multi-asset clearing, and credit intermediation to dozens of smaller clients under tighter credit terms and reduced minimums.
How traders use prime of prime
Retail traders rarely interact with a PoP directly, but the structure shapes every quote they receive. When a retail forex broker advertises ECN or STP execution, the liquidity feed usually originates from a PoP relationship with firms like LMAX, Saxo, Sucden, or Advanced Markets. The desk watches PoP relationships closely because they determine which banks are pricing into a broker’s stack, how deep the book runs during news events, and whether the broker can survive a liquidity squeeze. Institutional desks running multi-prime setups split flow across several PoPs to reduce counterparty concentration and improve fill quality. Retail traders can infer broker quality by checking disclosed liquidity providers in regulatory filings: a broker quoting six or more tier-1 banks via a credible PoP typically offers tighter spreads and more reliable execution than one routing through a single market maker.

Common misconceptions about prime of prime
Traders often assume that any broker claiming bank liquidity has direct tier-1 access. In practice, almost no retail broker holds a direct prime account; they sit two layers down through a PoP. A second misconception is that PoP automatically means no dealing desk. A PoP supplies liquidity, but the downstream broker can still internalise flow, B-book clients, or warehouse risk before passing residual exposure upstream. Finally, PoP is not a regulatory category. It is a commercial arrangement, so credit quality, segregation practices, and prime relationships vary widely between firms and should be verified through audited statements, not marketing pages.

Frequently asked
What is the difference between a prime broker and a prime of prime?
A prime broker is a tier-1 bank or large investment bank that offers clearing, financing, and liquidity directly to large institutional clients meeting strict capital thresholds, typically twenty-five million dollars or more. A prime of prime holds an account at a prime broker and resells that access in smaller slices to retail brokers, hedge funds, and proprietary firms. The PoP absorbs the credit risk of its downstream clients and bridges the capital gap between retail and institutional markets.
Who are the main prime of prime firms in forex?
Well-known PoP providers in the FX industry include LMAX Exchange, Saxo Bank, Sucden Financial, Advanced Markets, Swissquote, CFH Clearing, and Invast Global. Each maintains relationships with multiple tier-1 banks and packages aggregated liquidity for downstream brokers. The desk treats this list as a starting point only, since relationships shift, banks withdraw credit lines, and new PoP entrants emerge. Verifying current liquidity providers requires checking a broker’s most recent regulatory disclosure or audited financials.
Does my broker tell me if it uses a prime of prime?
Regulated brokers in jurisdictions such as the UK, Australia, and Cyprus generally disclose liquidity providers in their terms of business, best execution policy, or order execution documents. The naming convention varies: some list the PoP directly, others list aggregated banks without naming the intermediary. If a broker refuses to disclose its liquidity chain or markets vague phrases like deep liquidity without specifics, that opacity itself signals counterparty risk worth weighing.
Why did prime of prime firms become so important after 2008?
Before 2008, tier-1 prime brokers accepted smaller hedge funds and retail brokers as direct clients with relatively modest minimums. After the financial crisis, Basel III capital rules and tighter credit policies pushed prime banks to raise thresholds sharply, often above twenty-five million dollars in usable capital, and to drop smaller counterparties. PoP firms filled this gap by consolidating many smaller clients under one prime account, distributing credit, and meeting compliance requirements that individual retail brokers could not satisfy alone.
