Europe’s New Financial Firewall: Closing the Door on Iranian Terror Financing and Russian Sanctions Evasion

The structural overhaul of the European Union’s retail payments architecture, marked by the transition from the Second Payment Services Directive (PSD2) to the Third Payment Services Directive (PSD3), the directly applicable Payment Services Regulation (PSR), and the Instant Payments Regulation (IPR, Regulation (EU) 2024/886), is ostensibly designed to modernize Open Banking, foster competition between banks and FinTechs, and eradicate Authorized Push Payment (APP) fraud.

Yet beneath its consumer-protection and market-efficiency surface, this legislative triad represents one of the most consequential shifts in the European Union’s Counter-Terrorist Financing (CTF) and counter-sanctions apparatus.

Following the provisional political agreement in November 2025 and the publication of the finalized PSD3 and PSR compromise texts in April 2026 (setting up a 21-month implementation runway into early 2028), the EU has systematically dismantled the regulatory asymmetries that terrorist financiers and state-backed sanctions-evasion syndicates have exploited for nearly a decade.

When analyzed alongside the EU’s escalating restrictive measures against the Russian Federation, spanning the 19th package in October 2025, the 20th and 21st packages in April and July 2026, and the massive October 2026 designation of 1,569 military-industrial targets, as well as the intensified 2026 sanctions targeting the Islamic Republic of Iran, the Islamic Revolutionary Guard Corps (IRGC), and their unmanned aerial vehicle (UAV) and missile procurement networks, the new payments rulebook emerges as a formidable instrument of financial interdiction.

How Terrorist Networks Exploited Europe’s FinTech Loopholes

To appreciate the counter-terrorist financing and sanctions impact of the PSD3 and PSR package, one must first examine how illicit actors weaponized the legacy PSD2 and Second Electronic Money Directive (EMD2) regimes.

As traditional tier-one European commercial banks invested billions in automated sanctions screening, trade-finance scrutiny, and correspondent banking de-risking, both terrorist financing networks (including IRGC Quds Force proxies, Hezbollah financial facilitators, and Hamas fundraising cells) and Russian defense-procurement operatives pivoted toward the European FinTech perimeter.

Under PSD2 and EMD2, Electronic Money Institutions (EMIs) and Payment Institutions (PIs) were governed by minimum-harmonization directives that were transposed unevenly across the twenty-seven Member States.

Illicit networks routinely engaged in regulatory arbitrage by targeting lightly capitalized EMIs in permissive jurisdictions, leveraging EU passporting under the freedom to provide services to issue thousands of cross-border virtual IBANs (vIBANs), prepaid cards, and nested Banking-as-a-Service (BaaS) accounts across the single market.

Because PSD2 separated the regulatory regimes of EMIs and PIs and left operational fraud and conduct rules to national discretion, Russian shadow-fleet brokers and Iranian front companies could layer funds rapidly across multiple non-bank Payment Service Providers (PSPs), obscuring the ultimate originator and beneficiary before settling transactions through a single commercial clearing bank that lacked visibility into the underlying EMI sub-accounts.

PSD3: Closing Regulatory Gaps and Tightening FinTech Oversight

The finalization of PSD3 and the PSR in Spring 2026 ends this statutory fragmentation by moving core operational, security, and transparency rules from a directive into the directly applicable PSR, while using PSD3 to merge EMIs and PIs into a single, unified Payment Institution licensing and prudential regime.

By repealing both PSD2 and EMD2, PSD3 eliminates the legal distinction between electronic money issuance and payment services, subjecting all non-bank payment providers to harmonized capital requirements, strict governance and fit-and-proper mandates, rigorous fund-safeguarding rules, and mandatory winding-up plans.

Crucially for CTF and counter-proliferation enforcement, existing PSD2 and EMD2 license holders are not passively grandfathered into the new era; they must undergo mandatory transitional re-authorization within 27 months of entry into force.

For the scores of white-label EMIs and shell FinTechs that have historically turned a blind eye to high-risk onboarding from the Caucasus, Central Asia, the UAE, or Turkey, key transshipment hubs for Russian microelectronics and Iranian drone components, this re-licensing gauntlet acts as a systemic purge.

National competent authorities, operating under the indirect oversight of the Authority for Anti-Money Laundering and Countering the Financing of Terrorism (AMLA) and reinforced by AMLA’s 2026 mandates on Central Contact Points for cross-border PSPs, can now deny re-authorization to any payment institution that cannot demonstrate robust internal controls against terrorist financing and sanctions circumvention, as required by the European Banking Authority’s (EBA) Restrictive Measures Guidelines (EBA/GL/2024/14 and 2024/15, fully applicable since December 2025).

Direct Payment Access Brings Greater Scrutiny of Illicit Transactions

At the same time, PSD3’s amendment of the Settlement Finality Directive, which grants non-bank PSPs direct access to EU-designated payment clearing and settlement systems such as the Eurosystem’s TARGET infrastructure (aligned with Decision ECB/2025/2), fundamentally alters the supervisory bargain.

Previously, EMIs and PIs relied on commercial tier-one banks for indirect settlement sponsorship, creating a compliance blind spot where the commercial bank blamed the FinTech for faulty customer due diligence. In contrast, the FinTech relied on the bank’s outer perimeter screening.

While direct access to TARGET removes the commercial bank intermediary, it exposes non-bank PSPs directly to central bank operational resilience checks, mandatory Digital Operational Resilience Act (DORA) compliance, and direct scrutiny from the Eurosystem and AMLA.

A Payment Institution seeking direct clearing access can no longer hide nested Russian or Iranian commercial flows inside aggregated omnibus accounts held at a correspondent bank; every payment instruction hits the central settlement rails directly under the PSP’s own identifier, creating transparent, unaggregated telemetry for Financial Intelligence Units (FIUs).

Even more significantly, in the wake of the EU’s 20th and 21st sanctions packages against Russia in April and July 2026, which imposed sweeping transaction bans on dozens of Russian and third-country banks, banned interactions with Russian crypto-transfer platforms and the RUBx token, and targeted 14 third-country crypto platforms, Russian trade syndicates have desperately sought alternative fiat settlement channels inside Europe.

By forcing PIs that access central clearing systems to meet bank-grade risk and sanctions-screening standards, PSD3 ensures that direct settlement access does not become a backdoor for designated third-country financial institutions seeking to bypass the SWIFT and correspondent banking bans.

Exposing Front Companies Through Mandatory Identity Verification

The most immediate operational blow to both terrorist financing and Russian and Iranian sanctions evasion, however, comes from the convergence of the Instant Payments Regulation (IPR) and the PSR’s mandatory Verification of Payee (IBAN-to-name matching) and shifted sanctions-screening architecture.

Historically, both IRGC procurement agents and Russian military-industrial intermediaries, such as the 826 companies and 743 CEOs designated by the EU in October 2026, have relied on name-swapping or invoice manipulation.

Under this typology, a sanctioned entity or a terrorist front charity holds an account (or a nested IBAN) under its legal corporate registration, but instructs European senders or donors to input an innocuous, non-designated trade name, logistics company name, or humanitarian alias in the beneficiary name field of a SEPA credit transfer.

Because legacy SEPA payment rails routed funds solely based on the unique identifier (the IBAN) without cross-checking the beneficiary name string against the account holder’s actual legal identity at the receiving institution, fuzzy-logic screening engines at the sending bank saw only a benign company name and allowed the funds to pass.

Since October 2025, under the IPR for Eurozone instant euro transfers, and extending in 2027 to non-Eurozone PSPs and non-bank PIs/EMIs, before expanding under the PSR to all credit transfers across the EU regardless of speed or currency, this loophole is permanently closed.

Every PSP must now run an automated, free-of-charge Verification of Payee service before the payer authorizes the payment, instantly querying the receiving PSP to confirm whether the entered beneficiary name matches the legal name tied to the target IBAN. If there is a mismatch or a close match, the system alerts the payer immediately.

For Russian and Iranian evasion networks, this destroys the utility of front-name invoicing: if an EU importer attempts to pay a disguised invoice for mixed LNG cargoes (restricted under the 19th package) or dual-use aviation components, the pre-execution IBAN-to-name check forces the true registered account name to the surface, triggering immediate compliance freezes if the underlying holder is flagged, or exposing the deceptive invoicing practices of the intermediary.

Daily Sanctions Screening Targets Russian and Iranian Financial Networks

Furthermore, the IPR has revolutionized how sanctions screening itself is conducted across European payment rails.

Recognizing that screening millions of individual cross-border payments in real time within a ten-second instant-payment window generated massive false-positive rates without catching sophisticated, pre-layered evasion networks, Article 5d of the IPR shifted the paradigm for instant euro transfers (since October 2025) from transaction-by-transaction screening to mandatory, harmonized daily client base screening.

Every PSP must screen its entire client database, including all beneficial owners formatted under the strict standards of Implementing Regulation (EU) 2026/2354, immediately upon the publication of any new or amended EU targeted financial sanctions list, and at least once every calendar day thereafter.

In the context of the EU’s rapid-fire 2026 sanctions packages against Russia and Iran, such as the March 2026 designations of Iranian officials and cyber actors (including Emennet Pasargad), the July 2026 extension of the EU’s Iran drone and missile sanctions regime, and the massive April, July, and October 2026 Russian military-industrial listings, this rule eliminates screening latency.

The moment the Council of the European Union publishes an Implementing Regulation in the Official Journal adding a Russian shadow-fleet shipping manager or an IRGC procurement director to the consolidated freeze list, every bank and Payment Institution across the Union is legally compelled to screen its entire ledger against that update immediately, freezing the account before a single instant payment can be initiated or received.

Combating Terrorist Financing Through Anti-Fraud Enforcement

Complementing this identity-verification grid are the PSR’s stringent new anti-fraud, transaction-monitoring, and PSP liability mandates, which inadvertently serve as a force multiplier for Counter-Terrorist Financing.

Lone-actor terrorists, extremist cells, and state-backed cyber-financial operatives (such as Iranian and Russian state-aligned hacking groups) increasingly rely on social engineering, spoofing (impersonating bank employees or public authorities), and APP fraud to rapidly harvest illicit funds from European citizens and businesses, funneling the proceeds through mule accounts into crypto-asset off-ramps.

The April 2026 PSR compromise text introduces three powerful countermeasures that directly disrupt these CTF pipelines.

First, the PSR imposes full refund liability on PSPs not only for unauthorized transactions but also for bank/telecom impersonation fraud, and holds online platforms financially liable to PSPs if they fail to remove reported fraudulent financial advertisements or phishing infrastructure.

Faced with severe balance-sheet liability, European PSPs are deploying aggressive behavioral biometrics and anomaly detection to trap terrorist fundraising and mule-collection accounts simultaneously.

Second, the PSR explicitly requires receiving PSPs to freeze suspicious incoming transactions when anomaly indicators are triggered, preventing illicit funds from hopping across three or four European instant-payment accounts in seconds.

Third, the PSR establishes a clear GDPR legal basis for PSPs to share fraud-related intelligence, including compromised unique identifiers, mule IBANs, device fingerprints, and behavioral telemetry, through multilateral information-sharing arrangements.

In practice, because cyber-fraud mule networks and CTF/sanctions laundering networks use the same European money-mule infrastructure, inter-PSP intelligence sharing lets financial institutions collectively map and shut down the account networks illicit intermediaries use before law enforcement intervenes.

Closing Open Banking Loopholes Used by Sanctioned Operatives

Finally, the PSR’s overhaul of Open Banking, governing Account Information Service Providers (AISPs) and Payment Initiation Service Providers (PISPs), closes a subtle but growing technological vector for sanctions evasion and terrorist financing.

Under PSD2, sanctioned operatives in Tehran, Moscow, or third-country hubs often bypassed geographic IP blocks and direct bank onboarding controls by recruiting European straw directors to open local bank accounts, then connecting those accounts to third-party AISPs and PISPs.

By using PISP interfaces or automated screen-scraping fallback mechanisms, remote financial controllers outside the EU could aggregate balances across dozens of European straw accounts and initiate outbound payments without logging directly into the Account Servicing Payment Service Provider’s (ASPSP’s) web portal, thereby masking their foreign device telemetry and IP footprints from the bank’s security stack.

The PSR dismantles this obfuscation strategy while empowering legitimate RegTech surveillance.

By abolishing the fallback screen-scraping mechanism (except in strictly supervised contingency failures) and mandating that ASPSPs provide dedicated, standardized, high-performance APIs alongside mandatory consumer permission dashboards, the PSR brings total cryptographic and audit visibility to third-party account access.

Every PISP payment initiation and AISP data pull must now traverse a structured, authenticated API gateway where Strong Customer Authentication (SCA) credentials, token delegations, and third-party provider identities are rigorously logged.

If a single PISP interface or corporate treasury aggregator is used to initiate synchronized payments across ten seemingly unrelated shell companies held at different EU banks, a classic hallmark of an IRGC trade-splitting network or a Russian shadow-fleet bunkering operation, the standardized API logs and real-time permission dashboards generate an unmistakable digital signature.

Moreover, when combined with the harmonized FIU exchange templates under Article 31(2) of 6AMLD, any suspicious PISP-initiated transaction immediately captures both the underlying bank account telemetry and the third-party initiator metadata.

A New Financial Security Perimeter Against Terrorism and Sanctions Evasion

Ultimately, the transition from PSD2 to PSD3, the PSR, and the Instant Payments Regulation demonstrates how consumer-facing payment market reforms can be engineered to serve high-level national security and counter-proliferation objectives.

By folding EMIs into a single, re-verified Payment Institution regime, conditioning direct central-bank settlement access on rigorous resilience and compliance checks, enforcing universal IBAN-to-name verification, mandating immediate daily client-base sanctions screening, empowering receiving PSPs to freeze suspicious instant inflows, and locking down Open Banking APIs, the European Union has hardened its financial plumbing.

For terrorist financiers and the architects of Russian and Iranian sanctions evasion, the European retail payments landscape is no longer a fragmented playground of lightly supervised FinTechs and opaque virtual accounts, but a unified, identity-verified, and real-time interdiction perimeter.
