Forex brokers use internalization to manage their order flow efficiently, reduce costs, and hedge residual risk effectively.
Understanding internalization can help traders identify how their broker handles orders and whether there are any potential conflicts of interest.
📌 What is Internalization?
📌 Internalization is the process of matching customer orders within a broker’s system rather than executing them with an external liquidity provider (LP).
Instead of hedging each trade separately, the broker aggregates trades and offsets buy and sell orders internally.
✔ This reduces transaction costs since the broker doesn’t have to pay the LP spread.
✔ The larger the broker’s customer base, the easier it is to match opposing trades internally.
Example of Internalization:
1️⃣ Trader A buys GBP/USD (100,000 units).
2️⃣ Trader B sells GBP/USD (100,000 units).
3️⃣ The broker offsets these trades internally, eliminating market risk.
4️⃣ No external liquidity provider (LP) is involved, saving the broker money.
🚀 By internalizing trades, brokers can act like a mini exchange, matching buyers and sellers internally.
📌 Benefits of Internalization for Brokers
✔ Avoids paying LP spreads
✔ Provides better pricing to traders
✔ Reduces exposure to market risk
✔ Improves order execution speed
✔ Can still hedge any remaining (residual) risk
🚀 The goal of internalization is to reduce external transaction costs and provide competitive pricing while maintaining risk neutrality.
📌 How Internalization Works
A forex broker analyzes its trading book to determine the net exposure of a specific currency pair.
✔ If long and short positions offset each other completely, the broker has no exposure and does not need to hedge externally.
✔ If there is a remaining net exposure, the broker has two choices:
1️⃣ Accept the risk (Act like a B-Book broker).
2️⃣ Hedge the risk externally (Act like an A-Book broker).
📌 Example 1: Full Internalization (Zero Market Risk)
Let’s assume a broker has 10 million units of long GBP/USD and 10 million units of short GBP/USD.
📊 Broker’s Trading Book Before Internalization:
| Trader | Position | Volume (Units) |
|---|---|---|
| Trader A | Buy GBP/USD | 2,000,000 |
| Trader B | Sell GBP/USD | 2,000,000 |
| Trader C | Buy GBP/USD | 3,000,000 |
| Trader D | Sell GBP/USD | 3,000,000 |
| Trader E | Buy GBP/USD | 5,000,000 |
| Trader F | Sell GBP/USD | 5,000,000 |
| Total Buy | 10,000,000 | |
| Total Sell | 10,000,000 | |
| Net Exposure | 0 |
Since the broker has fully offset buy and sell orders, no market risk exists, and it does not need to hedge externally.
🚀 The broker profits by capturing the spread without taking any directional risk.
📌 Example 2: Partial Internalization (Residual Risk Hedging)
Let’s assume the broker now has 10 million units of long GBP/USD but only 8 million units of short GBP/USD.
📊 Broker’s Trading Book Before Internalization:
| Trader | Position | Volume (Units) |
|---|---|---|
| Trader A | Buy GBP/USD | 2,000,000 |
| Trader B | Sell GBP/USD | 2,000,000 |
| Trader C | Buy GBP/USD | 3,000,000 |
| Trader D | Sell GBP/USD | 3,000,000 |
| Trader E | Buy GBP/USD | 5,000,000 |
| Trader F | Sell GBP/USD | 3,000,000 |
| Total Buy | 10,000,000 | |
| Total Sell | 8,000,000 | |
| Net Exposure | +2,000,000 (Long GBP/USD) |
The broker has a residual long position of 2M GBP/USD, so it must decide:
✔ Hold the risk (B-Book the remaining position).
✔ Hedge externally with an LP (A-Book the residual risk).
📌 If the broker does not hedge, it will profit if GBP/USD rises but lose if GBP/USD falls.
📌 If the broker hedges externally, it removes market risk but incurs a transaction cost.
📌 How Brokers Hedge Residual Risk
If a broker chooses to hedge externally, it does NOT hedge each trade separately.
🚀 Instead, it aggregates all residual positions and places a single hedge order with an LP using a Volume-Weighted Average Price (VWAP).
✔ VWAP = (Total Notional Value) ÷ (Total Volume Traded)
Example:
| Trader | Position | Volume (Units) | Price | Notional Value |
|---|---|---|---|---|
| Trader A | Buy GBP/USD | 200,000 | 1.2508 | 250,160 |
| Trader B | Buy GBP/USD | 300,000 | 1.2510 | 375,300 |
| Trader C | Buy GBP/USD | 500,000 | 1.2512 | 625,600 |
| Total Volume | 1,000,000 | |||
| Total Notional Value | 1,251,060 | |||
| VWAP Hedge Price | 1.2511 |
🚀 Instead of placing three separate hedge orders, the broker places one bulk hedge at 1.2511.
✔ This reduces transaction costs.
✔ It prevents price slippage from executing multiple small trades.
📌 Summary: How Brokers Manage Orders with Internalization
| Scenario | Execution Method | Broker’s Profit Source | Risk to Broker |
|---|---|---|---|
| Fully Internalized Trade | Customer orders offset each other | Captures full spread | 🚀 No market risk |
| Partially Internalized Trade | Broker hedges residual exposure externally | Captures partial spread | 🚨 Residual market risk |
| Unhedged Residual Risk | Broker keeps exposure (B-Book) | Profits if market moves in its favor | 🚨 Losses if market moves against it |
✔ Fully internalized trades = No risk, full spread profit.
✔ Partially internalized trades = Residual risk that can be hedged.
✔ Unhedged residual risk = Broker takes directional market risk.
📌 Key Takeaways
🚀 Internalization allows brokers to reduce trading costs and capture the spread without hedging externally.
🚀 Brokers prefer to internalize trades because it avoids paying LP spreads.
🚀 Residual risk must be either hedged externally (A-Book) or held as a B-Book position.
🚀 VWAP hedging allows brokers to hedge efficiently by aggregating multiple customer trades.
🚀 The larger the broker’s customer base, the more effectively it can internalize orders.
By understanding how your broker manages orders, you can better assess their pricing model, execution method, and potential conflicts of interest.
✔ Do they offer direct market access (DMA)?
✔ Do they aggregate orders before hedging?
✔ Do they internalize orders or always hedge with LPs?
