On bonuses, Poland follows the EU line. The KNF enforces the product intervention rules that stop CFD providers from offering monetary or non-monetary incentives to retail clients. Deposit matches, welcome credits and trade-linked rewards on CFD or forex accounts are not permitted for Polish retail traders.
Where Poland diverges is leverage. Instead of capping retail forex and index CFDs at the usual EU limits, the KNF set a national rule allowing up to 100:1 on selected instruments, and it created an experienced retail client category. To qualify as experienced, a trader must meet conditions on past trading activity and volume, for example a set number of sizeable CFD trades over recent quarters. Higher leverage does not change the bonus position, though. The incentive ban still applies to everyone.
The bonus ban is about CFD and forex products, not every offer. A broker giving access to real shares can still run a free-share or fee-rebate promotion on a stock account, and crypto platforms under their own registration may still offer sign-up rewards. But if an incentive is attached to CFDs or forex and aimed at Polish residents, a compliant firm will not be paying it.
