Forex Trading Regulation in Poland
Forex trading in Poland operates under a robust regulatory framework designed to protect traders, ensure transparency, and maintain the stability of the financial system. The primary authority responsible for overseeing Forex brokers in Poland is the Polish Financial Supervision Authority (KNF), which enforces strict compliance standards for all regulated financial institutions.
MiFID II and Investor Protection
As a member of the European Union, Poland applies the Markets in Financial Instruments Directive II (MiFID II), which came into force in 2018. MiFID II introduced enhanced rules aimed at improving market transparency, strengthening investor protection, and reducing systemic risk across EU financial markets.
Under MiFID II, Forex brokers must meet rigorous operational and reporting standards. These measures significantly reduce the risk of fraud, ensure fair trading conditions, and safeguard the interests of retail and professional traders alike.
The Role of KNF in Forex Regulation
KNF is the central regulatory authority responsible for supervising the Polish financial market, including Forex brokers, banks, investment firms, and capital markets. KNF ensures that all licensed brokers operate in accordance with Polish law and EU regulations.
All Forex brokers offering services in Poland must either:
- be licensed directly by KNF, or
- operate under EU passporting rights while being registered with KNF.
KNF supervises brokers’ capital adequacy, internal controls, risk management systems, and transparency obligations, ensuring a high level of trust in the Polish Forex market.
KNF Regulation of Forex Brokers
The Polish Financial Supervision Authority plays a key role in protecting traders from unfair practices and ensuring the integrity of the Forex market in Poland.
What is KNF?
KNF (Komisja Nadzoru Finansowego) was established in 2006 and serves as Poland’s unified financial regulator. Its mission is to ensure the proper functioning, stability, and security of the financial market, as well as to protect investors’ interests.
KNF regulates investment services, Forex and CFD trading, securities transactions, and asset management activities, operating within the MiFID II framework.
Requirements and Restrictions for KNF-Regulated Brokers
Forex brokers regulated by KNF must comply with a strict set of requirements designed to protect traders and ensure financial stability:
- Capital Requirements. Brokers must maintain sufficient regulatory capital (at least €730,000 for market makers), ensuring they can meet their financial obligations and withstand market volatility.
- Leverage Limits. Leverage for retail clients is capped at 30:1, in line with ESMA and MiFID II rules, reducing the risk of excessive losses.
- Negative Balance Protection. KNF-regulated brokers are required to provide negative balance protection, ensuring traders cannot lose more than their deposited funds.
- Registration and Supervision. All brokers must be registered with KNF and are subject to ongoing supervision, reporting obligations, and compliance checks.
- Client Fund Segregation. Client funds must be held separately from the broker’s own operating capital, protecting traders’ money in case of financial difficulties.
- Investor Compensation Scheme. KNF-regulated brokers participate in the Polish investor compensation system, which may compensate eligible clients in the event of broker insolvency.
How to Check if a Forex Broker is Regulated by KNF
To verify whether a Forex broker is regulated or registered with KNF, follow these steps:
- Visit the official KNF website.
- Access the register of supervised entities.
- Search for the broker by name or license number.
- Review the broker’s regulatory status and scope of authorization.
- Cross-check the license details with the information published on the broker’s official website.
This process helps traders avoid unregulated or fraudulent brokers.

- Investor Compensation Scheme – Protection of client funds in case of broker insolvency.
- Strict Regulatory Oversight – Compliance with Polish and EU financial regulations.
