ANZ Banking Group (ANZ) set the margin on its new tier one transaction in the domestic retail market on July 9, at the same time disclosing that bookbuild volume was increased to A$1 billion (US$917.9 million) from an indicative A$750 million. The deal, ANZ Capital Notes, is ANZ's first retail transaction since it placed A$1.5 billion of lower tier two notes in March last year and its first tier one issue since the sale of A$1.3 billion, also in Australian retail format, in September 2011.
