While some commodity prices had pulled back, those for major Australian exports were still historically high with thermal coal having climbed more than 70% in the past few weeks. Iron ore has also been supported by expectations for more infrastructure spending by China.
With supply for many commodities constrained, Westpac has sharply revised up its forecasts for Australian resources this year.
"Given our new commodity price forecasts, fair value AUD models that do not include a subjective proxy for risk are screaming that it is heavily undervalued," said Westpac chief economist Bill Evans. "Accordingly we have lifted our AUD forecast by end 2022 from $0.73 to $0.76 above its long term average," he added. "With relatively high commodity prices through 2023, the AUD is expected to move back to $0.80."
