Things haven’t been that great at Citigroup Inc over the past year or so. Citi is one of the banks that ran into trouble with subprime mortgage loans and issues when things went south in the global financial crisis. However, that’s not all Citi has been having problems with. The company is expected to see a $600,000 fine by the Financial Industry Regulatory Authority.

FINRA is reportedly levying the fine due to the fact that Citi might have helped some derivatives clients avoid paying taxes on their dividends. Clearly, UBS is not the only bank aiding its clients in tax evasion. Additionally, it is clear that the specter of derivatives continues to haunt the financial system.

Some believe with proper transparency and regulation, there is nothing wrong with derivatives, while others think that these financial instruments should be outlawed altogether. In the end, it will be interesting to see what happens — and whether Citi really does have to pay up.
