A complete guide to financial crime and AML compliance

Financial crime isn’t something happening on the fringes of the financial system anymore, it runs through it. From everyday fraud affecting individuals to large-scale money laundering operations moving billions, the scale and impact continue to grow. For regulated businesses, that creates a clear expectation: prevent it, detect it, and prove you’re doing both effectively.

At the same time, the way firms approach compliance is changing. Traditional, manual processes are struggling to keep up with onboarding volumes, evolving criminal tactics, and tighter regulatory scrutiny. What once passed as acceptable is now being questioned, and in many cases, penalised.

This guide brings together the key elements of financial crime and AML compliance into one place. It covers how financial crime works in practice, what regulators expect from firms, where organisations are falling short, and how areas like identity verification and performance tracking are shaping modern compliance approaches. The aim is to give a clear, practical view of what AML looks like today and what it takes to get it right.

What is financial crime?

Financial crime encompasses a wide range of illicit activities that jeopardise the integrity and stability of our financial systems. From money laundering to fraud, to cybercrime, these illegal practices pose significant threats to economies and societies worldwide.

Financial crime refers to a category of illegal activities conducted within the financial sector. It involves deceptive, manipulative, or fraudulent practices aimed at obtaining illicit financial gains. These crimes can be committed by individuals, organisations, or even governments, exploiting weaknesses in regulatory systems and taking advantage of complex financial structures.

There are several forms of financial crime:

• Money Laundering: The process of making illegally obtained funds appear legitimate. It involves a series of transactions and techniques to disguise the origins of illicit money, making it difficult to trace and seize. Money laundering enables criminals to integrate ill-gotten gains into the legal economy.
• Fraud: Fraudulent practices come in various forms, including security fraud, insurance fraud, insider fraud, identity theft, and credit card fraud. Perpetrators manipulate information, misrepresent facts, or engage in dishonest schemes to deceive individuals or organisations and unlawfully obtain financial benefits.
• Insider Trading: Insider trading involves trading stocks or other securities based on non-public information. This illegal practice gives individuals an unfair advantage over other investors, decreasing market fairness and integrity.
• Tax Evasion: Tax evasion refers to the illegal act of intentionally avoiding paying taxes owed to the government. Individuals and entities may underreport income, or utilise offshore tax havens to evade their tax obligations.
• Cybercrime: In this digital era, financial crime has expanded its reach to cyberspace. Cybercriminals use hacking, phishing, ransomware attacks, and online scams to target financial systems, institutions, and unsuspecting individuals. The rapid advancement of technology poses new challenges for combatting financial crime in the virtual world.

What are the consequences of financial crime?

Financial crime can have wide-ranging consequences that affect individuals, businesses, and society as a whole. Some of the main consequences of financial crime include:

• Economic impact: Financial crime undermines economic stability and can lead to significant financial losses. Fraudulent activities such as embezzlement, money laundering, and insider trading can distort markets, minimise investor confidence, and create financial imbalances.
• Loss of trust and confidence: When people lose confidence in the integrity of financial systems, they may be less willing to invest, transact, or participate in economic activities, which can harm economic growth and development.
• Financial losses: Individuals and organisations that fall victim to financial crimes can suffer severe financial losses. Fraud, identity theft, Ponzi schemes, and cyber crimes can result in personal bankruptcy, ruined credit scores, and substantial financial hardships for victims.
• Regulatory and legal repercussions: Governments and regulatory authorities dedicate significant resources to investigating and prosecuting financial crimes. This involves conducting complex investigations, enforcing regulations, and prosecuting offenders. The costs associated with these efforts include investigations, legal proceedings, and increased regulatory oversight.
• Reputational damage: Financial crime can tarnish the reputation of individuals, businesses, and institutions involved. Businesses associated with financial crime can face public scrutiny, loss of business partnerships, and reputational damage that may take years to recover from.
• Increased compliance costs: Financial institutions and businesses often face increased compliance costs to prevent and detect financial crime. Regulations require them to implement robust systems and management, conduct due diligence, and monitor transactions more closely. These costs can be substantial and ultimately passed on to consumers and clients.

Financial crime in action: Major cases, fines and trends

Recent enforcement data paints a clear picture: financial crime often slips through because of familiar gaps, not sophisticated new methods. At a systemic level, the scale remains significant. Estimates suggest that close to €2 trillion is laundered across Europe each year, with detected cases rising steadily over time. That backdrop is reflected in enforcement activity across multiple sectors.

In banking, one of the most notable penalties saw Santander fined £107.8 million by the FCA for prolonged weaknesses in its AML controls. The issues weren’t hidden or complex — they centred on ineffective oversight of business accounts and ongoing monitoring failures.

The gambling sector has faced similar scrutiny. 888 was fined £9.4 million after allowing customers to deposit and spend large sums without proper checks, including one individual who was able to spend over £65,000 without sufficient source of funds verification. In another case, William Hill businesses were ordered to pay £19.2 million, with regulators highlighting situations where high-value activity went unchecked, including a customer spending £23,000 in just 20 minutes.

Criminal cases reinforce the same themes. A UK-based logistics company was used to facilitate a £30 million money laundering operation, operating through what appeared to be a legitimate business. Meanwhile, sectors like real estate continue to show vulnerabilities, with 68 estate agents fined more than £500,000 combined for failures such as not registering for AML supervision or maintaining adequate controls.

At the higher end of enforcement, large-scale failures have led to record penalties. Binance agreed to a $4.3 billion fine after significant AML and sanctions breaches, including allowing over 100,000 illicit transactions to pass through its platform without adequate intervention.

What ties these cases together is consistency. Weak customer due diligence, gaps in transaction monitoring, and slow responses to risk appear repeatedly. In many situations, controls existed on paper but weren’t applied in practice, or were undermined by poor oversight. Financial crime isn’t slipping through because firms lack policies, it’s slipping through because those policies aren’t working as intended when put under pressure.

What firms are expected to get right in AML compliance

Expectations around AML compliance have tightened, but the fundamentals haven’t changed. Firms are still judged on how well they apply the basics and how consistently they do it under pressure.

It starts with knowing who you’re dealing with.

Customer due diligence sits at the core of any AML framework, and that means more than collecting a few documents at onboarding. Firms are expected to build a clear, risk-based understanding of their customers, including who they are, how they operate, and where their funds are coming from. Where risk is higher, that scrutiny needs to go further, with enhanced checks that actually reflect the level of exposure.

Onboarding is only the starting point. Regulators expect firms to keep that understanding up to date, which means ongoing monitoring of customer activity. Transactions need to be reviewed in context, not in isolation, with systems capable of spotting behaviour that doesn’t line up with what’s expected. When something looks off, it has to be investigated properly, not ignored, delayed, or lost in a backlog of alerts.

Sanctions screening is another area where there’s little room for error. Firms are expected to check customers and transactions against relevant watchlists and act quickly when matches appear. This isn’t a one-time exercise either. Lists change, risks shift, and screening needs to keep pace.

There’s also an increasing focus on accountability. It’s no longer enough to point to policies and procedures sitting on paper. Firms need to show that controls are working in practice, with clear audit trails and evidence of decision-making. Senior management are expected to be involved, understand the risks, and take responsibility where things go wrong.

Technology plays a big part here, but simply having systems in place isn’t enough. Regulators are looking at how those systems are used — whether alerts are meaningful, whether data is accurate, and whether processes are efficient without cutting corners. Manual workarounds and fragmented tools tend to raise questions, especially as transaction volumes grow.

Ultimately, what firms are expected to get right comes down to consistency. Strong onboarding, effective monitoring, reliable screening, and clear accountability all need to work together. When one part falls short, it creates openings – and those are exactly what regulators are looking for.

The growing pressure on firms to get AML right

Financial crime hits everyone, from individual members of the public, right through to the largest financial institutions, but it’s those institutions and every other regulated entity who have to shoulder the burden of tackling financial crime head on. Perhaps many have been slow to prioritise the necessary solutions, since such solutions come with a cost. Whether that be resource costs, to increase headcount or new departments; or infrastructure costs, to deliver more up-to-date technology and hardware; or solutions costs, to bring in software platforms that can speed up and improve the accuracy of their AML efforts.

Many companies were greatly impacted by the pandemic and related fallout, with many still struggling to recover. That’s particularly the case of companies who were already slow to embrace the new technologies that were being introduced to more efficiently onboard new customers, instead continuing with non-digital KYC solutions. Whether that was for mortgages or loans, retail purchases, or maybe property leases, these methods were outdated and cruelly exposed by that initial lockdown, which precluded any face-to-face interaction between customer and company. This required them to immediately introduce counter-solutions in order to continue with business. Having established some form of baseline, the fall-out from that reactive situation produces a vicious circle – do you then invest funds that are scarce, in longer-term solutions, in order to make yourself more competitive and give a better customer experience; or do you muddle through with outdated systems and a ‘sticking-plaster solution’ and hope to catch up? The simple answer is obvious, but perhaps hard to swallow.

Subsequent legislative changes have, however, made the answer more palatable. Global AML efforts have been ramped up through 2021 and 2022, with both EU and UK legislation being introduced to force regulated entities to increase their levels of fraud detection, by investing in new systems that will deliver process efficiencies. The drive to deliver more efficient KYC/KYB Onboarding, through more thorough CDD, is reinforced by heavier and more personalised fines and sanctions, which make every company officer responsible, and culpable, for major discrepancies in data that create opportunities for financial crime.

So, regulated entities are now under increased pressure to deliver efficient AML processes and detect fraudulent activity, as are their company officers, which should be helping to slow down the growth of financial crime. That growth, however, is fuelled by huge financial investment by the criminal fraternity, who are happy to reinvest the proceeds of their activities in order to keep themselves ahead of the AML industry. Manual and traditional, spreadsheet-based solutions can no longer keep up with the volumes of data that need to be interrogated, in order to deliver the outcomes demanded. For any company dealing with anticipated volume growth, particularly where international data is involved, digital software solutions are the only sensible way forward. Whether those solutions are delivered partially or wholly in-house, or whether they are bought in, doesn’t matter – it’s the efficacy of the solution that is important.

The role of identity verification in preventing financial crime

Implementing robust ID&V processes is essential for both compliance and risk management in regulated firms. AML compliance professionals must verify the identities of clients to prevent fraudulent activities and ensure regulatory compliance. ID&V software can streamline this process by automating identity checks, verifying the authenticity of customer information, and reducing the risk of human error.

By incorporating ID&V technology into their compliance frameworks, teams can enhance the accuracy and efficiency of identity verification as part of wider AML processes, strengthening the overall risk management strategy. ID&V solutions enable the swift and accurate verification of customer identities using a variety of methods, including document validation, biometric authentication, and liveness verification. This not only enhances the efficiency of customer onboarding but also significantly reduces the risk of fraudulent activity by ensuring that individuals accessing products and services are who they claim to be.

Furthermore, the adoption of ID&V technology enables firms to conduct thorough and continuous monitoring of customer risk profiles. By implementing real-time identity checks, anomalies and suspicious or higher-risk customers can be promptly flagged for further investigation. This proactive approach enhances the ability of companies to detect and prevent money laundering or terrorist financing activities. AML compliance and ID&V technology can assist in automating the CDD and EDD process by flagging customers that warrant additional scrutiny. This ensures that compliance teams can allocate their resources efficiently, focusing on clients and high-value transactions that have a higher likelihood of posing AML risks.

Measuring AML success: The role of KPIs

In today’s digital age, regulated businesses in the UK face increasing challenges in combatting financial crimes. With the rise in sophisticated money laundering schemes and fraudulent activities, there’s an urgent need for compliance teams to ensure that financial crime prevention measures are up to scratch and continually evolve in line with new methods of perpetrating fraud and other forms of economic crime.

By focusing on the right Key Performance Indicators (KPIs), compliance teams can ensure they’re not only meeting regulatory requirements but also providing an efficient, user-friendly experience for their customers.

Abandonment rates

In financial services and other regulated businesses, a high abandonment rate can be a sign of a cumbersome verification process. Customers, while understanding the importance of compliance, also prioritise ease and speed. An increase in this KPI might mean that the onboarding or verification process is too lengthy or complex. Compliance teams should view this KPI as an indicator to evaluate ways to streamline processes without compromising on compliance.

Customer onboarding times

The time a compliance team spends per customer onboarding check can also be an insightful KPI. If checks are too quick, it might mean potential issues are being missed. Conversely, if they’re too long, it might signal inefficiencies in the process or a lack of necessary tools. This KPI can guide teams in refining their onboarding processes and deciding where technology could potentially be used to reduce the time it takes to welcome a new customer.

Financial penalties and sanctions

One of the critical KPIs for businesses is the tracking of financial penalties and sanctions. Financial penalties in the context of AML non-compliance can be substantial, sometimes amounting to thousands or even millions of pounds. By closely monitoring this KPI, businesses can gauge the financial impact of their current AML strategies and prioritise resources in areas which may be prone to breaches or lapses that have led to fines or sanctions in the past.

AML training completion and effectiveness

Ensuring that your business’ workforce is adequately trained to detect and deter instances of financial crime, fraud, and money laundering is paramount. This makes tracking training completion and effectiveness an important KPI in AML compliance.

Employees are often the first line of defence against money laundering and other financial crime so ensuring they are able to recognise suspicious activity or red flags, and are well-versed in the proper protocols for reporting and escalation is a significant tool in how your business mitigates risk. Make sure that staff not only complete mandatory training but truly understand and can apply their learnings within their day-to-day roles.

Implementing new regulations

Keeping track of the time it takes to implement new regulations and adapt AML compliance processes is a key KPI. With regulation evolving and changes being announced regularly, staying compliant increasingly demands agility from firms. Being able to adjust, change, and pivot processes to stay on top of regulatory changes is key. When new regulations are announced, measure how long it takes your firm to adapt existing systems and align processes with new regulatory guidance.
