Full ReviewCost Comparison
FCA-regulated brokers operate under stricter rules than offshore alternatives:
Leverage Caps
FCA retail clients are subject to ESMA leverage caps (e.g., 30:1 on major FX). Offshore brokers offer higher leverage — at significantly higher risk.
Negative Balance Protection
FCA requires negative balance protection for retail clients. Offshore entities may not provide this.
FSCS Coverage
Eligible cash deposits at FCA-regulated brokers may be covered up to £85,000 if the firm fails. This does not cover trading losses.
Regulatory protection reduces structural risk. It does not eliminate trading risk — leveraged products remain high risk under any regulation.
Risks & Considerations
- Even with FCA regulation, CFDs and leveraged products remain high risk
- FSCS covers broker insolvency on eligible deposits — not trading losses
- Losses can exceed deposits on leveraged positions if negative balance protection limits are not clearly understood
- Financing costs apply across all regulated brokers — regulation does not remove this cost
- Regulation protects the structure of the relationship — not trading performance
