INTRODUCTION TO SPECIAL ISSUE ON
COMMON OWNERSHIP AND INTERLOCKING
DIRECTORATES
Amelia Fletcher, Martin Peitz, &         Florence Thepot
Common ownership by institutional investors-of minority stakes across mul-
tiple competing firms-has become a subject of heated debate in the antitrust
community. Although often driven by portfolio diversification strategies, rather
than anticompetitive intent, common ownership can result, in some sectors, in
the concentration of financial ownership, with possible anticompetitive effects.
Over the years, competition authorities on both sides of the Atlantic have
taken note. For example, in 2018, the U.S. Federal Trade Commission held
a hearing on common ownership.1 In the same year, Margaret Vestager,
at that time the Competition Commissioner at the European Commission,
stated that the Commission is looking carefully at common ownership
given indications of its increase and potential for anticompetitive effects.2 In
2017, the Competition and Markets Authority (CMA) examined the extent of
common ownership in the banking, insurance, and grocery retailing industries
in the United Kingdom.3
Closely related, but currently less discussed, is the question of interlocking
directorates among competing companies (companies sharing corporate board
members). One key issue is whether these can soften competition, either on
their own or in combination with financial links. Although in the United States,
Section 8 of the Clayton Act expressly prohibits interlocking directorates
between competitors, there is no such prohibition in the EU (apart from Italy
in the financial sector). In spite of the prohibition in the United States, the
FTC recently stated that interlocks still raise competitive concerns.
