Global payments systems are under unprecedented strain as digital transactions proliferate and fraudsters scale up sophistication. The rise of account‑to‑account (A2A) transfers, mobile wallets, and cross‑border transactions has outpaced legacy risk systems, creating urgent demands for faster, more effective fraud detection and regulatory compliance. Payment fraud losses in the European Economic Area reached approximately €4.2 billion in 2024, with card payment fraud accounting for €1.33 billion and credit transfer fraud €2.2 billion, while account takeover attacks continue to rise sharply.
In response, financial institutions, payment networks, and RegTech firms are deploying artificial intelligence (AI) at scale, moving beyond basic rule‑based flags to real‑time, data‑driven systems capable of spotting nuanced patterns in massive transaction streams. In 2025, AI has shifted from a promising enhancement to a core defense mechanism embedded directly into payments infrastructure, with tangible case studies showing measurable impact.
Shifting patterns, shifting defenses
The scale of digital payments growth has put traditional risk controls under stress. Data from global e‑commerce and payments reports indicate that more than 56 percent of merchants now use generative‑AI tools for fraud and risk management, up sharply from 42 percent the previous year.
Against this backdrop, key industry players have introduced AI‑infused tools aimed at detecting threats earlier and with greater accuracy. SWIFT, the global interbank messaging network, began rolling out an AI‑powered fraud detection enhancement to its Payment Controls Service in January 2025. The system uses pseudonymized data from billions of transactions to flag suspicious activity in real time, enabling banks in Europe, North America, Asia, and the Middle East to respond more quickly than with legacy systems. SWIFT estimates that global fraud costs reached an estimated $485 billion industry‑wide in 2023, highlighting the imperative for advanced defenses.
Similarly, Mastercard has expanded its AI capabilities in consumer fraud risk solutions. The company’s tools scan numerous transaction data points to provide real‑time risk scoring, allowing banks to intercept scams before funds leave victims’ accounts. In UK testing, these AI enhancements improved early detection of high‑risk mule accounts by roughly 60 percent on average, enabling earlier intervention.
Predictive detection at scale
Large card networks and payments platforms are also integrating predictive AI models into transaction scoring systems. Visa’s research shows that AI‑augmented fraud analytics have been crucial in expanding fraud controls beyond traditional card rails into the growing A2A payment space. A pilot with Pay.UK, the operator of the UK’s real‑time payment system, uses predictive AI to analyze money flows and identify risk before fraud occurs, adapting detection models to a broader set of payment behaviors.
Industry research and pilot programs suggest that AI‑driven fraud detection tools can reduce overall fraudulent transactions by up to 70 percent, detect roughly 63 percent of fraudulent payments, and decrease false positives by about 40 percent compared to traditional methods.
These capabilities are significant in an era when real‑time and instantaneous payment rails offer little time for manual review and intervention, and when fraudsters routinely exploit speed and anonymity to evade static rule‑based controls.
Compliance beyond fraud: AML and KYC integration
AI’s role in payments goes beyond transactional fraud to encompass broader regulatory compliance functions such as Anti‑Money Laundering (AML) and Know Your Customer (KYC) processes. Regulators globally are calling for more sophisticated approaches to compliance as digital financial crime risks increase.
For example, the Financial Action Task Force (FATF) updated its standards in early 2025 to focus on risk‑based approaches that factor in digital technologies, including AI‑enabled systems for transaction monitoring and compliance. These amended standards and guidance encourage jurisdictions to consider AI tools as part of AML/CFT frameworks, including mechanisms for assessing risk in non‑face‑to‑face digital interactions.
Academic research also highlights emerging AI methods for compliance work. Recent studies propose AI frameworks for generating Suspicious Activity Reports (SARs) that help compliance teams draft narrative explanations faster and with fewer errors, blending automation with human oversight to improve AML workflows.
Such developments matter because high false positive rates in traditional AML systems have long burdened compliance teams and obscured true threats. AI‑enhanced models aim to reduce noise and focus investigators on meaningful alerts, potentially lowering operational costs while improving oversight.
Threat Intelligence Meets Machine Learning
Complementing transaction scoring and compliance automation are advances in AI‑driven threat intelligence. Security research shows that stolen credentials are rapidly monetized on illicit markets, often appearing for sale on underground forums within a short period after a breach, highlighting the urgency of real‑time fraud detection and credential risk monitoring. Official analysis from the 2025 Verizon Data Breach Investigations Report also shows that compromised credentials remain one of the leading vectors in breaches, involved in roughly 22 percent of incidents, with thousands of stolen credentials observed in underground marketplaces shortly after compromise.
Without timely threat intelligence, organizations take an average of 241 days to identify and contain a breach, leaving long windows of exposure. AI platforms that incorporate external threat feeds and behavioral insights help fraud teams close this gap by identifying upstream indicators of criminal campaigns and coordinating responses across multiple points of attack. These tools also monitor for synthetic identity and deepfake‑related fraud attempts, increasingly prevalent tactics that combine real and fabricated personal information to bypass legacy identity checks.
The combination of threat intelligence and AI risk scoring enables faster detection and more precise prevention, an important capability as fraud tactics evolve and scale.
Operational and regulatory hurdles
Deploying AI for fraud detection and compliance is not without challenges. Financial institutions must ensure model explainability, data privacy protection, and regulatory compliance across jurisdictions with differing rules. Industry risk assessments emphasize that explainability and audit capability are essential for regulatory acceptance, prompting institutions to implement governance frameworks that document how AI models make decisions.
Regulators such as those in the U.S., EU, and Asia have stressed that while innovation is welcome, AI deployments must meet standards of accountability, transparency, and fairness. Guidance from regulatory updates in 2025 reiterates that institutions bear responsibility for risks arising from AI systems and must integrate risk assessments, explainability, and oversight into their governance structures.
These expectations come as compliance teams grapple with data silos, legacy systems, and talent shortages, barriers that complicate integration and maintenance of advanced AI models. Institutions adopting AI must balance speed of deployment with robust controls to maintain consumer protection and meet regulatory scrutiny.
Collaboration and shared intelligence across borders
AI’s transformative potential in fraud and compliance extends beyond individual companies. Initiatives like SWIFT’s federated learning experiments illustrate how banks can share insights across borders without exposing proprietary data. In pilot programs involving millions of simulated transactions, federated AI models doubled detection effectiveness compared to models trained on isolated datasets, pointing to a future where combined intelligence enhances defense capabilities industry‑wide.
Cross‑institution collaboration and secure shared insights will become increasingly important as criminal networks operate globally and exploit regulatory gaps. AI platforms that support privacy‑preserving data sharing help institutions counter these threats while protecting sensitive information.
Frequently asked questions
Which types of fraud can AI detect?
AI can identify card fraud, account takeover, synthetic identity fraud, deepfake-assisted scams, and suspicious transactions in real time, as well as flag risky merchant or customer behavior.
What is the role of AI in AML and KYC compliance?
