In the high-stakes theater of European financial regulation, a contentious new front has opened between Brussels, the banking sector, and telecommunications operators. At the heart of the conflict is a multi-billion euro question: when a consumer is duped by a fraudster impersonating a bank employee, who foots the bill? The European Union is poised to overhaul the liability framework for payment fraud, signaling a departure from the traditional "consumer beware" doctrine toward a model that forces infrastructure providers to shoulder the cost of sophisticated scams.

The impetus for this regulatory shift is the alarming rise in Authorised Push Payment (APP) fraud, specifically "spoofing," where criminals manipulate caller ID technology to make phone calls or text messages appear as though they originate from a legitimate financial institution. According to a recent report by TechRepublic, the European Council is advancing legislation that would mandate payment service providers (PSPs), such as banks, to reimburse victims of impersonation fraud. However, the proposal introduces a radical twist: if the fraud was enabled by a failure in the telecommunications infrastructure—specifically the inability to verify the origin of a call—the liability could shift to the mobile network operators.

A Systemic Shift in Liability

This legislative maneuver represents a significant component of the broader Payment Services Regulation (PSR) and the third Payment Services Directive (PSD3). Historically, banks were only liable for unauthorized transactions—hacks or stolen cards. If a customer authorized a transfer, even under false pretenses, the loss generally fell on the individual. The new framework seeks to close this gap by recognizing that consumers cannot reasonably distinguish between a genuine bank call and a technically sophisticated spoof. As detailed by the European Council, the mandate requires PSPs to improve transaction monitoring and, crucially, share fraud data to create a united front against organized crime syndicates.

The banking industry has long argued that they are often the final link in a chain of failures that begin elsewhere—often on social media platforms or via telecommunications vulnerabilities. By introducing a mechanism where liability can flow to electronic communications service providers, the EU is acknowledging that financial institutions cannot unilaterally secure an ecosystem where the initial point of contact—the phone call—is fundamentally compromised. This approach aligns with the growing sentiment among regulators that security must be embedded in the infrastructure, not just the endpoint application.

Telecommunications Operators Push Back

The telecommunications industry has reacted with sharp resistance to the proposal, viewing it as an overreach that conflates carriage with content moderation. Industry bodies such as the European Telecommunications Network Operators’ Association (ETNO) and the GSMA have voiced concerns that the technical requirements for filtering spoofed calls are not as straightforward as regulators suggest. In a joint statement referenced by GSMA, operators argue that while they are committed to fighting fraud, holding them financially liable for banking losses ignores the technical realities of global signaling systems and the privacy constraints imposed by the ePrivacy Directive.

The core of the telco defense is that they act as neutral conduits. They argue that identifying a spoofed call in real-time requires analyzing signaling traffic that often originates outside the EU, passing through multiple transit carriers before reaching the victim’s network. Placing strict liability on the terminating network—the operator that delivers the call to the consumer—could incentivize operators to block legitimate traffic out of an abundance of caution, potentially disrupting critical communications. Furthermore, they contend that the banking sector’s own authentication protocols, or lack thereof, remain the primary vector for these losses.

The Verification of Payee Mechanism

Beyond the liability tussle, the EU is mandating technical countermeasures designed to alert consumers before money changes hands. A cornerstone of this strategy is the "Verification of Payee" (VoP) system. As outlined in the Instant Payments Regulation adopted by the European Parliament, PSPs will be required to verify that the recipient’s IBAN matches the name provided by the payer. If there is a mismatch, the consumer must be warned. This friction is intended to break the psychological spell of the scammer, forcing the victim to pause and reconsider the transfer.

While VoP is a proven deterrent in markets like the Netherlands and the UK, it is not a silver bullet. Fraudsters have adapted by coaching victims to ignore these warnings, spinning narratives that the mismatch is due to a "technical error" or that the money is being moved to a "safe account"—a tactic specifically effective in impersonation fraud. Consequently, the EU’s focus has remained on the impersonation aspect itself. If a consumer ignores a VoP warning, they might be deemed "grossly negligent," potentially relieving the bank of liability. However, if the consumer was manipulated by a caller ID that the telco failed to authenticate, the negligence argument becomes much harder to sustain.

The Shadow of the British Model

European regulators are closely watching the United Kingdom, which has taken an even more aggressive stance on reimbursement. The UK’s Payment Systems Regulator (PSR) has implemented a mandatory reimbursement requirement for APP fraud, split 50-50 between the sending and receiving banks. As reported by the Payment Systems Regulator, this model forces receiving firms—often smaller payment institutions or crypto-friendly banks used as mule accounts—to tighten their onboarding controls or face insolvency. The EU model differs by explicitly dragging telcos into the equation, a step the UK has not yet formally taken in terms of direct financial liability for spoofing.

The divergence in approach highlights a philosophical split. The UK model focuses on financial incentives within the banking system to choke off money mule networks. The EU proposal, by contrast, attempts to sanitize the communication channels leading up to the fraud. European banks, represented by the European Banking Federation, have generally welcomed the move to share the burden, arguing that they cannot be the sole insurers for a digital ecosystem rife with security holes they did not create and cannot fix.

Technical Hurdles and Implementation Risks

Implementing a liability shift involving telcos requires a robust mechanism for attribution. If a spoofed call occurs, the bank must prove the impersonation took place and that the telco failed to prevent it. This necessitates a level of data sharing between banks and mobile operators that currently does not exist at scale. It raises complex questions regarding GDPR and data privacy: does a bank have the right to query a telco’s call logs to verify a customer’s claim of being spoofed? Without automated, real-time cooperation, the claims process could become a bureaucratic quagmire.

Moreover, the definition of "impersonation" is subject to legal wrangling. Does it apply only to exact number spoofing, or does it cover "neighbor spoofing" (looking like a local number) or simply using a generic name in an SMS header? The text of the regulation will need to be surgically precise to avoid endless litigation. Critics warn that if the bar for telco liability is set too high, the provision will be toothless; set too low, and it could financially destabilize smaller virtual network operators (MVNOs) that lack the capital to upgrade their core networks.

The Role of Big Tech and Platforms

While the current spotlight is on telcos, the conversation is rapidly expanding to include online platforms. Many scams originate not via cold calls but through investment ads on social media or search engines. While the current proposal highlighted by TechRepublic focuses on the bank-telco dynamic regarding spoofing, there is growing pressure to include "Big Tech" in the liability loop. If a platform accepts money to display a fraudulent advertisement that leads to a loss, banks argue the platform should contribute to the reimbursement.

This "shared responsibility" framework is the new battleground for digital regulation in Europe. The days of siloed regulation—where telcos, banks, and tech platforms operate under disparate rules—are ending. The convergence of these industries in the execution of fraud is forcing a convergence in their regulatory obligations. The EU’s move regarding spoofing is likely just the first domino; eventually, any entity that facilitates the reach of a fraudster may find itself receiving an invoice for the damages.

Timeline and Industry Preparedness

The legislative process is currently in the trilogue phase, where the Parliament, Council, and Commission negotiate the final text. Once adopted, there will be a transition period, likely 18 to 24 months, for the industry to adapt. During this window, banks and telcos must build the APIs and dispute resolution mechanisms necessary to handle liability claims. This period will likely see frantic lobbying to define the technical standards for what constitutes "preventable" spoofing.

For industry insiders, the message is clear: the cost of fraud is being internalized into the infrastructure. Compliance officers at banks and regulatory affairs directors at telecommunications firms must prepare for a regime where fraud prevention is no longer a value-add service or a customer care issue, but a direct line item on the balance sheet. The era of passing the buck to the consumer is effectively over; the era of determining exactly which corporate entity holds the buck has just begun.
