Sydney: Australia’s government sold A$11 billion (Dh31 billion, $8.5 billion) of 11-year debt notes in its biggest-ever bond transaction, as investors hungry for higher yields set aside concerns stubborn budget deficits will cost the nation its AAA credit rating.

It’s the third time in less than six months the South Pacific country has set a new borrowing record. It exceeds the A$9.3 billion issued at a sale of December 2021 notes last month and the A$7.6 billion from last October’s debut 30-year deal. The November 2028 securities were priced to yield 3.005 per cent, the Australian Office of Financial Management said Wednesday.

The government has been ramping up issuance as it struggles to rein in its budget deficit and seeks to finance a debt pile that’s expected to top A$600 billion in 2020. Investors have been clamouring for Aussie debt even as tighter US monetary policy drives a slump in global bond markets. The size of Wednesday’s sale shows that concerns about Australia’s capacity to keep its top credit score are being set aside as the nation’s relative prudence and weaker economic outlook makes the debt look attractive relative to US Treasuries, according to Robert Mead, managing director at Pacific Investment Management Co in Sydney.

“You’re looking at a bond that’s gone from nothing to a benchmark in one day,” Mead said. He said before the announcement there was more than A$20 billion of demand for the offering.

While ratings companies refrained from taking action following December’s midyear budget update, S&P Global Ratings has had a negative outlook on the country since July. Treasurer Scott Morrison is scheduled to hand down his next fiscal plan in May.

Prospect of Fed tightening

The new bond will eventually roll into the basket of securities underpinning the ASX 10-year futures contract that is, along with similar three-year and 20-year products, a major fixed-income derivative Down Under. The basket currently includes notes with maturities ranging from April 2026 to May 2028.

The benchmark 10-year rate has held within a range of 2.63 per cent to 2.83 per cent this year, following the global bond market sell-off late in 2016 that was spurred by Donald Trump’s election as US president and the prospect of Fed policy tightening. It was at 2.83 per cent as of 3:18pm in Sydney.

The face value of federal government securities is expected to reach A$498 billion by the end of June and rise to A$604 billion in the 2019-20 financial year. The government’s net debt is predicted to peak at 19 per cent of economic output in 2018-19 after climbing to 18.1 per cent in the current fiscal year, according to official projections.

The 2028 bond has a coupon of 2.75 per cent and the transaction was managed by Australia & New Zealand Banking Group Ltd, Commonwealth Bank of Australia, Deutsche Bank AG and Westpac Banking Corp.
