KNF's CFD Review Stays Open as XTB Shares Slide
The Polish Financial Supervision Authority (KNF) confirmed on Monday 17 August 2026, via spokesperson Jacek Barszczewski speaking to Strefa Inwestorow, that its review of how contracts for difference are offered to retail clients remains active, with no published timetable or proposed measures, according to Finance Magnates (18 August 2026). XTB shares fell roughly 7% across two trading sessions in the same window, though the outlet does not establish a direct causal link between the statement and the price move. The review sits alongside a PLN 20 million penalty KNF imposed on XTB in March 2026 over client-assessment and disclosure failings, which XTB has appealed and which is therefore not final.
Poland's financial regulator has reiterated that its scrutiny of contracts for difference (CFDs) is unfinished business, a message that landed as shares in Warsaw-listed broker XTB extended a two-session decline. The statement, reported by Finance Magnates on 18 August 2026, adds little procedural detail but keeps an open regulatory question hanging over a firm whose earnings are heavily concentrated in the product under review.
What happened
Jacek Barszczewski, KNF's communications director, told Polish financial news site Strefa Inwestorow on Monday 17 August 2026 that "work in this area continues" and that the regulator "will report the conclusions once it is complete," according to Finance Magnates. No consultation paper, draft rule or implementation date has been published since KNF Chairman Dariusz Adamski first flagged the review publicly in May 2026, when he said access to complex, high-risk instruments was too easy and should be restricted for investors who do not understand the risks, per the same report. XTB shares closed 4.1% lower at PLN 169.18 on Monday and traded at PLN 164.56 by late morning Tuesday, down a further 2.7% and nearly 7% below Friday's close, while the WIG20 index fell 1.1% on Monday, Finance Magnates reported.
Why it matters
The review follows a PLN 20 million (about $5.5 million) penalty KNF imposed on XTB in March 2026, citing deficiencies in client knowledge assessments, target-market controls and risk disclosures covering parts of 2022 and 2023, according to Finance Magnates. KNF also objected to a list highlighting high-performing clients, saying it could give a misleading view of CFD risk and created conflicts of interest given commercial relationships with those featured. XTB has requested reconsideration of that decision, meaning the fine is not yet final, the outlet noted. For XTB, the stakes are structural rather than incidental: CEO Omar Arnaout said in February 2026 that CFDs generate about 95% or more of group revenue, though the broker has stated an ambition to reduce that share to about 70% through products such as spot crypto and equities, per Finance Magnates.
What it means for traders
For clients and prospective clients of Polish-regulated brokers, the practical position is unchanged for now: no new rules, thresholds or product restrictions have been announced, and KNF has given no indication of when that might change. Traders assessing broker choice amid open-ended regulatory reviews may find it useful to consult independent comparative work, such as our Best Regulated Broker winners, alongside how such assessments are constructed, detailed in our methodology. Nothing in the KNF statement or the March 2026 penalty implies any finding about brokers other than XTB, and the fine itself remains under appeal.
What to watch
Three markers will matter over coming months: whether KNF publishes a formal consultation or draft rule following its comments in May and August 2026; the outcome of XTB's reconsideration request over the March 2026 fine; and whether XTB's diversification plans, aimed at cutting CFDs to roughly 70% of revenue, show measurable progress in future disclosures. Share-price moves in the interim, including the nearly 7% two-session decline reported by Finance Magnates, reflect market reaction rather than any confirmed regulatory outcome, and should be read alongside the absence of a published timetable from KNF.
FAQ
Has KNF announced new CFD rules? No. According to Finance Magnates (18 August 2026), KNF has said only that its review continues, with no timetable or proposed measures disclosed as of that date.
Is the March 2026 fine against XTB final? No. XTB has requested reconsideration of the PLN 20 million penalty, which means it is not final, Finance Magnates reported.
Why does the review matter so much for XTB specifically? Because CEO Omar Arnaout said in February 2026 that CFDs account for about 95% or more of the group's revenue, according to Finance Magnates, making the outcome of any restriction material to its business mix.
