United States v. Citigroup, Inc., 2013 WL 123123 (D.D.C. 2013)
The case United States v. Citigroup, Inc.
Does Citigroup, Inc.'s proposed merger violate antitrust laws by substantially lessening competition or tending toward creating a monopoly in the banking industry?
Under the Clayton Act, Section 7, a merger or acquisition is prohibited if in any line of commerce or in any activity affecting commerce in any section of the country, the effect of such acquisition may be substantially to lessen competition, or to tend to create a monopoly.
The court ruled that Citigroup, Inc.'s proposed merger would indeed violate antitrust laws, as the acquisition could substantially lessen competition in key banking markets, particularly in retail lending and specialized financial services.
