Open Banking's Blind Spot: Report Exposes Illicit Payment Risks

LONDON, UK – February 18, 2026 – A bombshell report from cyber-finance intelligence platform FinTelegram has cast a harsh spotlight on the European Open Banking sector, raising critical compliance questions about how high-risk merchants, including potentially unlicensed online casinos, may be accessing regulated payment networks. The findings center on payment facilitator Klyme and its infrastructure partner, UK-based Open Banking provider Yapily, following the inadvertent leak of an internal compliance email that exposed alarming gaps in how user complaints are handled.

The incident, which has sent ripples through the fintech community, underscores a growing tension between rapid technological innovation and the slower, more deliberate pace of regulatory compliance. It suggests that the complex, layered architecture of modern payment systems may be creating blind spots that can be exploited for illicit activities, leaving consumers and the financial system exposed.

The Anatomy of a Compliance Failure

The controversy began with a simple mistake: a misdirected email. In February 2026, a customer who had filed a complaint months earlier received a message intended for internal discussion at Klyme. The email detailed the handling of their December 2025 report, which concerned an online casino allegedly operating without a license in the Netherlands—a jurisdiction with a strictly regulated online gambling market.

According to FinTelegram's analysis of the communication, the response was not to investigate or escalate action against the high-risk merchant. Instead, the email suggested that the reporting user’s own access to payment services may have been restricted. Compounding the confusion, the message referenced the implementation of “geographic access controls in Lithuania,” a detail entirely irrelevant to a complaint rooted in alleged breaches of Dutch law. This raises serious questions about the firm's understanding and application of jurisdiction-specific regulations.

At the heart of the issue is the operational structure between Klyme and Yapily. Klyme Ltd, which launched in 2024, operates as a technology provider, offering businesses a seamless way to integrate direct bank-to-bank payments. However, the company’s own terms explicitly state it is not a regulated financial institution. Instead, it clarifies that “All payment transactions and related regulatory responsibilities are managed by licensed third-party providers.”

In this case, that licensed provider is Yapily, which supplies the regulated Open Banking infrastructure—the API-driven rails that connect to customer bank accounts. Klyme acts as the intermediary, building its service on top of Yapily’s foundation and handling the direct integration of merchants like the online casino in question. This operational model, while common, appears to have created a critical gap in oversight, as highlighted by the bungled complaint response.

Open Banking's Layered Risk

The FinTelegram report uses this incident as a case study for a systemic vulnerability within the Open Banking ecosystem: the “layered model.” While this structure promotes innovation by allowing agile tech companies like Klyme to build user-friendly solutions on top of robust, regulated infrastructure, it also diffuses responsibility. FinTelegram suggests this separation of duties may allow high-risk or unlicensed operators to slip through the cracks by onboarding with an intermediary rather than directly facing the scrutiny of the underlying regulated entity.

This raises difficult questions for infrastructure providers like Yapily. The incident puts a spotlight on the due diligence processes these regulated firms have in place for their partners. It is unclear how rigorously they monitor the compliance of intermediaries or the nature of the sub-merchants those partners bring onto the network. When a payment facilitator like Klyme sits between the merchant and the regulated payment rails, it can obscure the ultimate source of the transaction, creating a regulatory blind spot.

The case highlights the inherent paradox of Open Banking. The system was designed to increase competition and security by moving away from traditional card networks. Yet, by creating new chains of interconnected players, it introduces new complexities for preventing financial crime. The report from FinTelegram argues that transaction monitoring, escalation processes, and the ultimate allocation of responsibility become dangerously ambiguous in such a multi-layered environment.

The Unanswered Question of Accountability

When a potentially illegal transaction is processed, who is ultimately responsible? Is it the regulated infrastructure provider like Yapily, which holds the license? Or is it the merchant-facing intermediary like Klyme, which onboarded the client? The FinTelegram report suggests that, in practice, accountability may be getting lost between the layers.

This ambiguity directly challenges the enforcement efforts of national regulators. The Dutch Gambling Authority (Kansspelautoriteit), for example, actively works to protect consumers by taking action against unlicensed operators, which includes ordering payment providers to block transactions to illegal gambling sites. The ability of the casino at the center of this complaint to allegedly operate and process payments via a sophisticated Open Banking channel represents a direct circumvention of this regulatory framework.

This incident is not happening in a vacuum. Regulators across the European Union are already intensifying their scrutiny of payment intermediaries and the broader fintech ecosystem. The EU is in the process of rolling out new legislative packages, such as the Capital Requirements Directive (CRD VI), aimed at strengthening cross-border financial oversight. The findings from FinTelegram are expected to add fuel to this fire, drawing regulatory attention specifically to the allocation of accountability across Open Banking payment chains.

A Regulatory Wake-Up Call for Fintech

The issues exposed by FinTelegram are emblematic of the broader challenges facing the fast-growing fintech industry. The gambling sector, in particular, is notoriously high-risk for money laundering and requires stringent controls. Any payment provider servicing this industry is expected to have ironclad compliance protocols to ensure they are not facilitating payments for unlicensed entities. The delay in addressing the initial report from December 2025 to February 2026 further highlights a potential lack of urgency or capability in managing high-risk merchant activity.

This single misdirected email has peeled back the curtain on potential systemic failures in risk management. It serves as a cautionary tale for the entire Open Banking sector, demonstrating how quickly operational mishaps can escalate into significant regulatory and reputational crises. As Open Banking continues its expansion across Europe, the pressure will mount on all participants—from infrastructure providers to the tech firms building on their platforms—to prove their compliance frameworks are robust enough to prevent the system from being co-opted for financial crime. The industry may find that the era of ambiguous responsibility is rapidly coming to an end, with regulators poised to enforce clarity and demand accountability from every link in the payment chain.
