Compare the best brokers, banks, crypto exchanges and forex brokers in Poland for 2026. Only KNF-regulated platforms reviewed.
Poland's financial markets are regulated by the KNF (Komisja Nadzoru Finansowego), which oversees banks, insurance companies, investment firms, and the Warsaw Stock Exchange (GPW). All platforms listed for Poland are KNF-authorised or operating under a MiFID II passport. Poland has one of Central Europe's most active retail investment communities.
Polish bank deposits are protected up to 100,000 EUR equivalent in PLN per institution by the Bankowy Fundusz Gwarancyjny (BFG). Investment accounts at authorised brokers are covered up to €22,000 (or 90% of the claim) under the Polish investor compensation scheme. BLIK — Poland's mobile payment system — is increasingly accepted for funding investment accounts, alongside standard bank transfers.
Polish investors have strong domestic options: PKO BP Makler, mBank eMakler, and XTB (which originated in Poland) are among the most used platforms. XTB in particular is listed on the Warsaw Stock Exchange. Capital gains in Poland are taxed at a flat 19% Belka tax (podatek Belki), named after the finance minister who introduced it — brokers typically handle this withholding automatically.
All platforms listed for Poland are regulated by Polish Financial Supervision Authority (KNF) or are passported into Poland under EU MiFID II / ESMA rules. We do not list unregulated or offshore brokers.
