Smurfing is a money laundering technique of breaking large sums of money into smaller transactions as a way to avoid detection by keeping all transfers below the reporting Anti-Money Laundering (AML) threshold. By spreading illicit funds across multiple accounts, criminals minimize the risk of triggering red flags. For example, banks in the US are required to report cash transactions over $10,000 and file a suspicious activity report (SAR).
Smurfs use small transactions repeatedly and spread them through multiple accounts to stay below regulatory reporting limits. The term “smurfing” has its roots in the drug traffickers’ slang. Apparently, criminals often purchased small quantities of various substances or ingredients they needed to combine and produce the end product. Today, regulatory laws like the USA Patriot Act strengthened anti-money laundering efforts by requiring reports for deposits, withdrawals, or currency exchanges over the reporting threshold.
