AUD looks to the price of iron ore as a critical input.

How much longer does the (respite?) rally in iron ore last is addressed by a local press piece published Tuesday, Australian Financial Review: Iron ore's incredible rebound could be short-lived (may be gated)

From the piece:

UBS -

  • "It's being driven partly by restocking from the National Day holidays and so the question mark is how long that continues for"
  • "Underlying demand is still not that strong, and we don't have conviction yet as to how long the current rally can endure."

Morgan Stanley -

  • forecasting will average $US85 a tonne during the final quarter of 2021
  • We believe iron ore can dip further into the fourth quarter of 2021 and first quarter of 2022, but expect a bounce by the second quarter, as China’s steel production curbs are lifted and infrastructure stimulus filters through
