Financial Crimes Enforcement Network (FinCEN) warned banks to look out for Russian oligarchs investing in commercial real estate to circumvent sanctions.  U.S. Treasury Department's watchdog, FinCEN, is responsible for writing and coordinating the enforcement of anti-money laundering rules for financial institutions.  More:  FinCEN said commercial real estate transactions involve highly complex financial transactions that affect transparency and allow bad actors to hide illicit funds.  According to the alert, sanctioned individuals are investing in high-end luxury properties and common-use properties throughout the country.  It added that the relative stability of the country's commercial real estate industry and the high value of properties provide a way to store large amounts of money and generate a steady income.  This week's alert is an addition to a previous alert issued in March 2022 that identifies real estate, luxury goods, and other high-value assets involving sanctioned Russian elites.
