Foresight News, according to Bloomberg, U.S. prosecutors had been investigating Signature Bank’s cooperation with cryptocurrency customers before regulators suddenly took over the bank last weekend. Justice Department investigators in Washington and Manhattan are looking into whether the New York bank did enough to detect potential money laundering by its customers, such as scrutinizing who opens accounts and monitoring transactions for signs of crime, people familiar with the matter said. Two people who spoke on condition of anonymity said the U.S. Securities and Exchange Commission (SEC) is also investigating the matter. The head of the U.S. SEC said at the time that if violations of federal securities laws were found, they would investigate and take enforcement actions.
