Combating the illicit use of digital assets

Since its creation in 1865, the United States Secret Service has been tasked with safeguarding the integrity of the nation’s economy. Initial efforts focused on putting an end to rampant counterfeiting taking place in the years following the American Civil War, a time in which as much as 30% of circulating currency was thought to be illicit. As individuals and organized networks evolved and sought new ways to defraud the public, special agents and criminal investigators with the Secret Service have responded, applying their experience and expertise to preventing other financially motivated crimes such as illicit credit card schemes, fraudulent wire transfers, computer fraud and abuse, and, most recently, the illicit use of digital assets, including cryptocurrencies to facilitate crimes like ransomware attacks.

What are digital assets?

The term digital assets refers broadly to representations of value in digital form, regardless of legal tender status. For example, digital assets include cryptocurrencies, stablecoins and nationally backed central bank digital currencies. Regardless of the label used, or the various definitions ascribed to them, digital assets can be used as a form of money or be a security, a commodity or a derivative of either. Digital assets may be exchanged across digital asset trading platforms, including centralized and decentralized finance platforms, or through peer-to-peer technologies.

Why does the Secret Service investigate the use of digital assets?

The Secret Service is responsible for detecting, investigating, and arresting any person who violates certain laws related to financial systems. In recent years digital assets have increasingly been used to facilitate a growing range of crimes, including various fraud schemes and the use of ransomware. 

While the United States has been a leader in setting standards for regulating and supervising the use of digital assets for anti-money laundering and countering the financing of terrorism purposes, poor or nonexistent implementation of those standards in some jurisdictions abroad is presenting significant illicit financing risks that harm the American people and our foreign partners. For example, transnational organized criminals often launder and cash out their illicit proceeds using digital asset service providers in jurisdictions that have not yet effectively implemented international standards. 

The ongoing growth in decentralized financial ecosystems, peer-to-peer payment activity and obscured blockchain ledgers presents additional risks to the American people and our foreign partners. When digital assets are abused and used in illicit ways it is in the national interest to take actions to mitigate these risks through law enforcement action and other government authorities. The U.S. Secret Service is committed to doing its part to safeguard the nation from illicit activity involving digital assets.
