Mizuho Financial Group
The current Mizuho Securities is established by a merger between Shinko Securities and the former Mizuho Securities. The former Shinko Securities (a former equity-method affiliate of Mizuho Financial Group) and the former Mizuho Securities (a former consolidated subsidiary of Mizuho Financial Group) merged on 7 May 2009. The effective date of the merger was postponed a couple of times due to the financial crisis. The surviving entity was the former Shinko Securities, which changed its name to Mizuho Securities upon the merger. After the merger, Mizuho Financial Group holds 59.51% equity ownership of the new Mizuho Securities.
