Accounting systems, compliance (management control with corporate governance) and regulatory loopholes may create banker trading opportunities that negatively and / or positively thrilled individuals and bank trader groups may want to grasp in a culture where free market and free spirit thinking, talking and acting can enfold under favorable economic conditions. It may not pay though.
