FCA Client Asset Rules: A Guide to CASS

Last updated · SpreadComparison

The Financial Conduct Authority (FCA) sets out stringent rules to protect client money and assets held by regulated firms in the UK. These guidelines, primarily found within the Client Asset Sourcebook (CASS), are crucial for ensuring investor confidence and maintaining the integrity of the financial system. For 2026, firms continue to adhere strictly to these comprehensive requirements.

Methodology: spreads are typical values recorded on each broker's raw/standard retail account during London–New York overlap hours, taken from the brokers' own published pricing pages and live platform data, then averaged. Commission is stated separately where it applies. Spreads are variable and widen around news and outside main sessions.

What is CASS?

CASS, or the Client Asset Sourcebook, is a section of the FCA's Handbook of rules and guidance. It details how firms must hold and safeguard client money and custody assets. The primary goal of CASS is to ensure that if a firm fails, client assets can be returned quickly and efficiently, separate from the firm's own funds.

Key Principles of CASS

Firms subject to CASS must adhere to several core principles:

* Segregation: Client money and assets must be held separately from the firm's own money and assets.

* Record Keeping: Accurate and up-to-date records must be maintained for all client assets, allowing for easy identification of ownership.

* Reconciliations: Regular reconciliations between internal records and external statements (e.g., bank statements, custodian statements) are mandatory to identify and resolve discrepancies promptly.

* Acknowledgement Letters: For client money held in a third-party bank account, firms must obtain acknowledgement letters from the bank confirming that the money is held on trust for clients.

* Risk Management: Firms must have robust systems and controls in place to manage the risks associated with holding client assets.

Types of Client Assets Covered by CASS

CASS rules apply to a broad range of client assets, categorised mainly into:

1. Client Money (CASS 7): This includes cash balances held on behalf of clients, such as funds deposited for trading or investment.

2. Custody Assets (CASS 6): These are investments or other assets held by a firm on behalf of a client, such as shares, bonds, or fund units.

3. Mandates (CASS 8): Rules concerning mandates firms hold over client assets, such as power of attorney.

The Importance of Segregation

Segregation is the cornerstone of client asset protection. When a firm segregates client money, it means those funds are placed in a separate bank account, distinct from the firm's operational accounts. This ensures that in the event of the firm's insolvency, client money is protected from the claims of the firm's creditors.

Similarly, custody assets are held in a manner that clearly identifies them as belonging to clients, often through nominee companies or direct registration, rather than being part of the firm's proprietary holdings.

Reporting and Oversight

Firms are required to submit regular CASS reports to the FCA, detailing their compliance with the rules. These reports provide the regulator with an overview of how firms are handling client assets and money, allowing for proactive oversight and intervention where necessary. The FCA also conducts thematic reviews and inspections to assess firms' adherence to CASS.

Worked Example: Client Money Segregation

Imagine a forex broker, regulated by the FCA, receives £10,000 from a client for trading purposes. Under CASS 7 rules, the broker cannot simply put this £10,000 into their main company bank account. Instead, they must deposit it into a designated client money bank account, held with an approved bank. This account must be clearly titled as a 'client money account' and the bank must acknowledge in writing that the funds are held on trust for the broker's clients. If the broker were to go out of business, the £10,000 would remain protected in that separate account and would be returned to the client, rather than being used to pay the broker's debts. This mechanism ensures client funds are ring-fenced.

Choosing an FCA Regulated Broker

When selecting a broker for trading, especially in markets like forex, it is paramount to choose one regulated by the FCA. This ensures that your funds and assets are subject to the rigorous protections outlined in CASS. A regulated broker offers peace of mind, knowing that your capital is held securely and transparently. Consider firms like Vantage, a featured partner, which typically offers raw spreads from 0.0 pips and operates under stringent regulatory oversight, providing a secure trading environment.

FAQ

What is the FCA's Client Asset Sourcebook (CASS)?

CASS is a set of rules within the FCA Handbook that dictates how regulated firms must hold and safeguard client money and custody assets, ensuring they are protected in the event of firm insolvency.

How does CASS protect my money if my broker goes bust?

CASS mandates the segregation of client money and assets from the firm's own funds. This means your money is held in separate accounts and cannot be used by the firm's creditors, allowing for its return to you if the firm becomes insolvent.

Do all financial firms follow CASS rules?

CASS rules apply to firms authorised by the FCA that hold client money or custody assets. However, the specific rules (e.g., CASS 6, CASS 7) apply depending on the nature of the assets held and the firm's business model.

What is the Financial Services Compensation Scheme (FSCS)?

The FSCS is the UK's compensation fund for customers of authorised financial services firms. If a CASS firm fails and your assets cannot be returned (e.g., due to a shortfall), the FSCS can compensate you up to a certain limit, currently £85,000 per eligible person per firm.
