B-Book: How Brokers Handle Risk in Financial Markets

When a retail broker chooses to take the opposite position of a client’s trade, it can either accept the risk itself or offload it to another entity in the market.

If the broker decides to retain the risk, the process is referred to as “B-Book execution.”

“B-Book execution” essentially means the broker is acting as the counterparty to the client’s trade.

This type of trade can also be described as being “B-Booked.”

When the broker takes on this risk, it is often referred to using terms like:

The risk has been “absorbed.”The risk has been “retained.”

By choosing to “hold” the risk, the broker keeps it in-house (“absorbed”) and manages it internally (“retained”).

While this approach allows the broker to potentially profit from client losses, it also exposes the broker to potential losses if the market moves against its position.

Let’s explore examples to illustrate both scenarios.

Example 1: Broker Profits from Market Movement

Consider a scenario where a client, Alex, buys 10,000 units of a currency pair, say GBP/JPY, at an exchange rate of 150.00. The broker “B-Books” this trade, taking the opposite position by selling 10,000 units of GBP/JPY.

The market rate drops to 149.00.

Alex, facing a loss, decides to exit the trade and sells back the 10,000 units at the new rate of 149.00.

Alex’s Loss Calculation:Profit/Loss=(Exit Price−Entry Price)×Position Sizetext{Profit/Loss} = (text{Exit Price} - text{Entry Price}) times text{Position Size}Profit/Loss=(Exit Price−Entry Price)×Position Size−1,000=(149.00−150.00)×10,000-1,000 = (149.00 - 150.00) times 10,000−1,000=(149.00−150.00)×10,000Broker’s Profit Calculation:Profit/Loss=(Entry Price−Exit Price)×Position Sizetext{Profit/Loss} = (text{Entry Price} - text{Exit Price}) times text{Position Size}Profit/Loss=(Entry Price−Exit Price)×Position Size 1,000=(150.00−149.00)×10,000 1,000 = (150.00 - 149.00) times 10,000 1,000=(150.00−149.00)×10,000

In this case, by retaining the market risk, the broker earns a profit of 1,000 units of currency.

Example 2: Broker Suffers a Loss

Now, let’s consider a situation where the market moves against the broker.

Alex buys 10,000 units of GBP/JPY at an exchange rate of 150.00. Again, the broker “B-Books” the trade, taking the opposite position.

This time, the market rate rises to 152.00.

Alex decides to close the trade and sells the 10,000 units at the higher rate of 152.00.

Alex’s Profit Calculation:Profit/Loss=(Exit Price−Entry Price)×Position Sizetext{Profit/Loss} = (text{Exit Price} - text{Entry Price}) times text{Position Size}Profit/Loss=(Exit Price−Entry Price)×Position Size 2,000=(152.00−150.00)×10,000 2,000 = (152.00 - 150.00) times 10,000 2,000=(152.00−150.00)×10,000Broker’s Loss Calculation:Profit/Loss=(Entry Price−Exit Price)×Position Sizetext{Profit/Loss} = (text{Entry Price} - text{Exit Price}) times text{Position Size}Profit/Loss=(Entry Price−Exit Price)×Position Size−2,000=(150.00−152.00)×10,000-2,000 = (150.00 - 152.00) times 10,000−2,000=(150.00−152.00)×10,000

In this scenario, the broker incurs a loss of 2,000 units of currency due to the adverse market movement.

Potential Ethical Concerns

One of the significant challenges with B-Book execution is the potential conflict of interest it creates.

Since the broker profits when clients lose, there may be an incentive for unethical practices that increase the likelihood of client losses. This concern has led to skepticism about the fairness of B-Book execution.

While most brokers operate transparently, this inherent conflict of interest has prompted traders to scrutinize brokers’ practices closely.

In the next section, we’ll explore another approach brokers use to manage market risk: transferring it to external participants through “A-Book execution.”
