KNF Keeps CFD Review Open as XTB Shares Fall Nearly 7%
The Polish Financial Supervision Authority (KNF) said on Monday 17 August 2026 that its review of how contracts for difference are offered remains active, according to comments from communications director Jacek Barszczewski reported by Strefa Inwestorow. No timetable or proposed measures have been disclosed. XTB shares, which closed 4.1% lower on Monday and were down a further 2.7% by late Tuesday morning, have fallen nearly 7% over the two sessions, underperforming the WIG20 index and named European peers. The regulatory uncertainty compounds an existing PLN 20 million penalty against XTB, which the broker is appealing.
Poland's CFD market has been under regulatory scrutiny since May 2026, when KNF Chairman Dariusz Adamski first said publicly that the authority was examining how domestic and cross-border firms offer contracts for difference, including how they test client knowledge and experience. That thread resurfaced this week, with the watchdog confirming the review is ongoing but offering no further detail on scope or timing.
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 the outlet. KNF has not published a consultation paper, draft rule or implementation date since Adamski's May comments, in which he said access to complex, high-risk instruments was too easy and should be restricted for investors who do not understand the risks, according to Finance Magnates.
XTB shares closed 4.1% lower at PLN 169.18 on Monday and traded at PLN 164.56 by late Tuesday morning, down a further 2.7% and nearly 7% below Friday's close, according to Finance Magnates. The WIG20 index declined 1.1% on Monday, meaning XTB's fall diverged from the broader Warsaw benchmark and from four European peers named in the same reporting.
Why it matters
The regulatory question sits close to the core of XTB's business. Chief Executive Officer Omar Arnaout said in February 2026 that CFDs generate about 95% or more of the group's revenue, though the broker has stated an ambition to reduce that share to roughly 70% through products including spot crypto and equities, according to Finance Magnates. Any tightening of CFD distribution rules in Poland would therefore bear directly on the concentration of XTB's earnings, even before considering the outcome of the review itself.
The review also follows a PLN 20 million (about $5.5 million) penalty KNF imposed on XTB in March 2026. The regulator cited deficiencies in client knowledge assessments, target-market controls and risk disclosures, and said the conduct covered parts of 2022 and 2023, according to Finance Magnates. KNF also objected to a list highlighting high-performing clients, saying the presentation could give a misleading view of CFD risk and that commercial relationships with people on the list created conflicts of interest. XTB has requested reconsideration of that decision, meaning the fine is not yet final.
What it means for traders
For clients and prospective clients of Polish-regulated CFD providers, the practical position is unchanged for now: no new rules, restrictions or timetable have been announced. What has changed is the visibility of regulatory attention on how CFD suitability and risk disclosure are handled, an area regulators across Europe have examined with varying outcomes. Traders assessing brokers on regulatory standing may find it useful to consult independent comparisons; see our Best Regulated Broker winners for one such reference point, alongside an understanding of how such assessments are compiled, set out in our methodology.
What to watch
Three threads run in parallel. First, whether KNF issues a consultation paper or draft rule, and on what timetable, following Adamski's May remarks and Barszczewski's confirmation this week that work continues. Second, the outcome of XTB's reconsideration request over the March penalty, which remains unresolved. Third, whether XTB's share price stabilises relative to the WIG20 and its European peers, or whether further regulatory disclosures extend the recent divergence.
FAQ
Has KNF proposed specific new rules for CFDs? No. According to Finance Magnates, the regulator has confirmed the review is active but has not published a consultation paper, draft rule or implementation date.
Is the PLN 20 million fine against XTB final? No. XTB has requested reconsideration of the March 2026 decision, according to Finance Magnates, which means the penalty is not yet final while the appeal proceeds.
Why does the review matter so much to XTB specifically? 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 broker's earnings particularly sensitive to any change in how CFDs may be offered to Polish clients.
