Financial Warfare: Sanctions and Watchlists Disrupt Terror Funding Networks Amid International Conflict
In early March, U.S. Treasury Department’s Financial Crimes Enforcement Network (FinCEN) released a statement informing American financial institutions that the Financial Action Task Force (FATF), an intergovernmental body that establishes international standards for anti-money laundering, countering the financing of terrorism, and countering the financing of proliferation of weapons of mass destruction (AML/CFT/CPF) recently updated its lists of jurisdictions with strategic deficiencies in this regard, and asking them to factor these findings into their day-to-day regulatory compliance operations.1 In wake of the ongoing war in Iran however, this message is best understood as more than a routine regulatory update, but as part of a much broader and increasingly urgent global effort to combat illicit finance, one that is now visibly intersecting with real-world geopolitical conflict.
The Financial Action Task Force’s efforts to identify jurisdictions with systemic weaknesses in combatting financial crime have proven effective in recent years. Countries identified in these reviews often move to make the necessary reforms to address their deficiencies in order to be removed from the group’s well-known black and grey lists, which signal the global financial system as to where risks are highest. Countries placed on the FATF’s blacklist are viewed as posing systemic threats of illicit finance due to “significant strategic deficiencies” in combating money laundering and terrorist financing.1 Not surprisingly, Iran remains one of the most prominent and persistent concerns; a jurisdiction that appears on this list year-in and year-out. Despite years of engagement, the FATF continues to warn that Iran has not adequately addressed deficiencies found its financial system, particularly those tied to terrorist financing. In fact, Iran’s notorious shadow banking network and means of maintaining illicit channels that funnel cash-flow to their destabilizing regime continue to expand in their reach.
Highlighting this trend was a recent move by the U.S. Treasury to sanction ten individuals accused of funneling more than $100 million to Hezbollah, the Iran-backed militant group. Members of the network include individuals based in various countries, including Lebanon, Syria, Poland, Slovenia, Qatar and right next door in Canada. Each of the named individuals have been accused in their own right of laundering money, arms and telecommunications equipment in sanctions-evading schemes through six companies that have also been sanctioned since 2020.2 The Treasury’s findings reveal the terror-funding initiative was backed by a sophisticated, multi-layered financial network that was used obscure origin, ownership, and purpose of funds, thus making it difficult for authorities to both identify and thwart to this point. These efforts were largely backed by three of the most common methods for laundering funds at the international level seen today, those being:
- Use of front companies and layered business networks: Where ownership structures were often disguised by putting businesses in the names of family members or associates, while the sanctioned individuals retained actual control,
- Trade-based money laundering: Where funds were moved under the cover of commercial transactions and were able to be transferred across international borders while appearing like ordinary business payments, and
- Use of currency-exchange houses: Allowing for the movement of large sums of money outside the oversight of the traditional banking system.
This network also exposed weaker regulatory environments where financial transparency (and the regulation governing this) was limited, while also leveraging positions tied directly to government-linked entities and development programs to both access and direct the movement of funds. These findings highlight where FinCEN’s guidance and the established FATF framework move from theory to practice. For years, analysts and regulators have warned that Iran has developed extensive financial networks that are working outside of the box in order to evade sanctions and move money globally through informal channels, shell companies, and intermediary institutions. These networks are not abstract; they are the very mechanisms that enforcement actions like the recent sanctions are targeting. The FATF’s continued classification of Iran as high-risk reflects the systemic nature of these activities, not just a growing series of isolated incidents. Unfortunately, with respect to national security, when funds are funneled through opaque financial systems to groups like Hezbollah, they enable real-world activities ranging from military operations to regional destabilization. In this context, AML/CFT compliance becomes a form of financial warfare.
This is precisely why FinCEN emphasizes that U.S. financial institutions must integrate FATF findings into their risk frameworks. The identification of high-risk jurisdictions is more than passive guidance, instead it directly informs how banks screen transactions, evaluate customer relationships, and even decide where to allocate their own capital. A jurisdiction flagged by the FATF can trigger enhanced due diligence, transaction monitoring, or even complete de-risking, allowing banks to avoid becoming a pawn in a much larger and more dangerous game. In today’s environment, this cycle is accelerating, and as geopolitical tensions involving Iran, the United States, and other regional parties intensify, financial channels are becoming arguably just as important as physical ones. As such, the global fight against money laundering and terrorist financing will remain a high-stakes effort to disrupt the financial lifelines that spread instability across the world.
