SYDNEY, Feb 22 (Reuters) - Australia sold A$11 billion ($8.5 billion) of 2028 bonds at a yield of 3.005 percent, the federal government's funding agency said on Wednesday.
The bond issue was the largest ever sold by the Australian Office of Financial Management, eclipsing the previous record of A$9.3 billion of debt a month earlier.
The offer attracted A$20.9 billion worth of bids at the clearing margin of 14 basis points, which is at the tighter end of the initial guidance of 13.5 basis points to 16.5 basis points over the implied yield of 10-year bond futures, it said.
The bonds, rated triple A by the three major ratings agencies, will pay a coupon of 2.75 percent and mature on November 21 2028.
ANZ, Commonwealth Bank of Australia, Deutsche Bank (DE:DBKGn) and Westpac Institutional Bank jointly led the issue which will settle on March 2. ($1 = 1.3002 Australian dollars)
