Federal regulators have finally unveiled their proposal for the Volcker Rule, a linchpin of the Dodd-Frank Act that would restrict proprietary trading by many financial firms and require expansive new compliance programs for banks to monitor and report on their trading activity.

The 298-page plan, presented last week by the Federal Deposit Insurance Corp. and the Securities and Exchange Commission, foremost prohibits banks from โ€œtrading on their own account,โ€ to deter them from making risky investments such as what led to the financial crisis in 2008. (The proposal also contains a series of exemptions for when proprietary trading is acceptable.)
