Rogue Trading Below the Radar
Posted by John Bates
It is interesting to note that Kerviel was not only experienced on the trading floor, but he also had a background in middle office risk management technology. It may have been this knowledge that enabled him to manipulate the bank's risk controls and thus escape notice for so long.
Still, it is perplexing that fraud on such a scale can go on without detection for so long, even if Kerviel did have an insider's knowledge of the firm's risk management systems. Internal risk controls are not something that a financial firm can take for granted, left to run unchecked or unchanged for months or years.
The detection of criminal fraud or market abuse is something that must happen in real-time, before any suspicious behaviour has a chance to lose a firm money or to move the market. Pre-trade risk management is paramount, with trading limits specified and checked in real-time. Internal controls should be monitored for possible manipulation, again in real-time. The good news is that technology does exist in the form of real-time surveillance software from companies can analyse data transactions by the millisecond.
Financial institutions need to start looking inward to improve standards, regardless of current regulation. Otherwise the culture of greed and financial gain at all costs will encourage more and more Kerviels.
