Citigroup’s problems with its proprietary MAT/ASTA municipal arbitrage funds just keep growing. A recent Wall Street Journal article by Suzanne Barlyn entitled “Citi Units Must Pay $6.4 Million Over Muni-Arbitrage Loss,” which concerns Citi’s disastrous MAT/ASTA municipal arbitrage funds, reports a significant $6.4 million award issued against Citigroup in a MAT/ASTA case by a Financial Industry Regulatory Authority (FINRA) arbitration panel. Despite their high risks, the funds were marketed as an alternative to municipal bond portfolios. The funds also falsely emphasized their strong risk management and controls.
