Mining stocks could receive a boost after iron ore prices continued a stellar run, at fresh seven-year highs.
“The China stimulus-led rally is nowhere better reflected than in the iron ore market, which is up 70 per cent this year amid strong demand,” ANZ economist Adelaide Timbrell wrote.
“The rally received an additional boost recently from supply side issues. Vale reduced its guidance on output for 2021, as it struggles to overcome issues relating to the reopening of dams associated with their operations.”
And in a risk to Australian supply, on Thursday, the Pilbara Ports Authority issued a cyclone warning and said it was clearing large vessels out of the Port Hedland export hub.
“A La Nina weather system is likely to increase the number of cyclones that hit the West Australian coast. In the past this has resulted in higher than normal levels of disruptions to iron ore exports,” Ms Timbrell said.
However, the China Iron and Steel Association said BHP had assured it that the adverse weather conditions would not affect its monthly shipment volumes.
Airbnb jumps on debut
Shares in Airbnb’s initial public offering were priced at $US68 and the stock soared past that during its first session of trade, closing at $US144.71.
However, the company has not turned an annual profit since its launch in 2008 and it is not expected to do so this year either, despite a better-than-expected third quarter.

Australian dollar hits 2.5 year high
Overnight, the Australian dollar pushed through 75 US cents to hit a two-and-a-half-year high, as commodity prices rose strongly.
The euro also jumped after the European Central Bank (ECB) expanded its stimulus, but not by as much as some investors had expected.
ING global head of macro Carsten Brzeski said the ECB did not present “a big new bazooka”, and rather offered “a well-engineered extension of all well-known instruments to ensure that the current level of monetary accommodation is extended until at least the spring of 2022.”
The British pound fell as post-Brexit trade talks were extended to the weekend.
The US dollar also weakened after data showed that the number of Americans filing for unemployment benefits for the first time rose last week, as COVID-19 cases continued to climb, leading to more restrictions.
