Some life returned to the domestic corporate bond market last week. The stand-out issuer was Commonwealth Bank, rated AA-, which added A$1.5 billion to its January 2015 floating rate notes to take outstandings to A$2.5 billion.The line was opened last October, at a spread of 115 basis points over bank bills, and this latest increase was priced at 110 bps over bank bills.National Wealth Management Holdings, rated A+, followed the example of ANZ Wealth Australia the week before, and added $120 million of three-year FRNs to its August 2015 line. The increase was priced at 200 bps over bank bills and takes outstandings to $300 million. The line was originally opened at $130 million in August 2010, with minor top ups later that year.Nordic Investment Bank (rated AAA) added A$200 million to its April 2022 line. The increase, priced at 112 bps over CGS, takes outstandings to $500 million.SPI Australia Electricity & Gas (rated A-) has returned to the market after an absence of 15 months. The company sold A$205 million of 10-year bonds at a very competitive spread of 205 bps over swap. The spread was no doubt helped by the inclusion of coupon step-ups of 25 bps, 50 bps and 100 bps should SPI's credit ratings fall to 'BBB/Baa2', 'BBB-/Baa3' or 'BB+/Ba1', respectively, in the A$175 million tranche. An identical A$30 million tranche was sold without coupon step-up provisions.While the company has a significant capital expenditure program in front of it, the outlook on its S&P rating is stable, and Moody's rates it at A1/Stable.  Volkswagen Financial Services Australia (A-) completed the week with a A$150 million five-year bond issue. The issue was upsized from $100 million and priced at 170 bps over swap.      In New Zealand, electricity and gas distributor Vector Limited, rated BBB+, completed a NZ$263 million, five-year subordinated bond issue. The bonds will pay a fixed coupon of seven per cent per annum. Auckland Council, rated AA, was back in the market, raising NZ$50 million for 10 years. The bonds were priced at 140 bps over swap.
