The article "The CPA's Role in Fighting Money Laundering" by Abel and Gerson (2001) highlights how accountants play a crucial role in detecting and preventing financial crimes. Since 9/11, anti-money laundering (AML) laws like the Know Your Customer (KYC) Act and the Foreign Account Tax Compliance Act (FATCA) have expanded dramatically. Below, I update the key financial figures from the article, discuss how effective these laws have been in fighting terrorism, and reflect on the ongoing debate around privacy and practicality.

When Abel and Gerson (2001) published their article, they estimated global money laundering ranged between $584 billion and $1.46 trillion annually. Adjusted with current global data, the UN Office on Drugs and Crime (UNODC) now estimates that money laundering represents about 2-5% of global GDP, or roughly $800 billion to $2 trillion per year (UNODC, 2024).

The authors compared this to national economiesat the time, the United Kingdom's GDP was about $1.28 trillion and Spain's was $531 billion. Today, those figures have grown to approximately $3.64 trillion for the U.K. and $1.72 trillion for Spain (World Bank, 2024).

They also cited the Bank of Credit and Commerce International (BCCI), which had around $20 billion in assets when it collapsed in the late 1980s. Adjusted for inflation, that equals roughly $55 billion in today's dollars (U.S. Bureau of Labor Statistics CPI Inflation Calculator, 2024). These updates show how large-scale financial crimes can rival the economies of entire nationsreinforcing why accountants must remain vigilant.

Post-9/11 AML reforms were designed to trace and disrupt terrorist financing, but results have been mixed. Laws like FATCA and the USA PATRIOT Act improved the ability of financial institutions to share data and flag suspicious transactions. The Financial Action Task Force (FATF) reports that these efforts have helped identify and block numerous illicit networks (FATF, 2024).

However, terrorism financing often involves smaller, decentralized amounts of money, which are harder to detect through standard AML reporting. The U.S. Treasury's 2024 National Illicit Finance Strategy acknowledges that while AML laws have made terrorism financing riskier and more visible, they are not sufficient on their own. Terrorist groups now exploit informal transfer systems, cryptocurrencies, and trade-based laundering (FinCEN, 2024).

So, while AML laws have improved global cooperation and transparency, their direct impact on stopping terrorism has been limited but meaningful. They remain an essential tooljust not a complete solution.

Some critics argue AML and KYC laws violate privacy and impose excessive compliance costs. Groups like the ACLU have raised concerns that constant financial monitoring could infringe on civil liberties (ACLU, 2023). Recent court challenges, such as those involving the Corporate Transparency Act (CTA), show ongoing constitutional debates about government overreach (U.S. District Court, 2024).

However, most courts have upheld AML reporting as a legitimate part of protecting national security. The real issue may not be the intent of these laws, but their execution. The current system often generates large volumes of low-value suspicious activity reports (SARs), burdening smaller institutions without always helping law enforcement (FinCEN, 2024). A more risk-based, targeted approach could help strike a balance between privacy and public safety.

Personally, I believe AML laws are necessary but should be modernized. Financial surveillance should be tightly controlled, transparent, and focused on high-risk casesprotecting both national security and individual privacy.

As financial professionals, we are often the first line of defense against money laundering. To stay prepared, CPAs and financial managers can:

Stay educated through AICPA or ACAMS AML training to keep up with evolving typologies (AICPA, 2024).

Use a risk-based approach to evaluate clientsapplying enhanced due diligence for higher-risk clients or transactions.

Recognize red flags, such as structuring, rapid fund transfers, or inconsistent business activity.

Document and report suspicious activity through SARs, following FinCEN's current guidelines.

Leverage technology like transaction-monitoring systems, but ensure human oversight remains central.

By combining technical knowledge with professional skepticism, accountants can detect unusual patterns and help prevent illicit finance from flowing through legitimate businesses.

AML laws since 9/11 have certainly expanded the global framework for fighting financial crime and terrorism. While they are not flawlessand often criticized for being burdensomethey have made it much harder for illicit actors to hide in the formal banking system. For accountants, understanding these laws is more than a compliance requirement; it's part of protecting the integrity of the global financial system.
