The domestic corporate bond market will see A$12.5 billion of bonds mature this month. This is the largest monthly volume of maturities, as currently scheduled, to the end of 2020.Yet new issuance volume for the month is modest, and is following the soft issuance trend that has been in place since the start of the year. It is rare for annual net issuance volume to be negative - it hasn't happened since the 1990s.With $74 billion of corporate bonds maturing this year, the second largest annual volume yet, net new issuance could again be very low.Helping with the replacement task was Westpac (rated AA-), which issued $2.15 billion of three-year floating rate notes. The notes were priced at 100 basis points over bank bills, two bps wider than where NAB priced a similar sized three-year issue three weeks ago.Some reasonable issuance volume was also provided by the Sydney branches of Bank of Tokyo-Mitsubishi (rated A+) and Overseas-Chinese Banking Corporation (rated AA-).Bank of Tokyo-Mitsubishi sold $500 million of four-year FRNs, priced at 150 bps over bank bills.
