The Australian Dollar After Hauser's Warning: Reading a Speech-Driven Asia Session

Key takeaways

1. The Australian dollar rose 0.1% to $0.7013 in Asian trade on Wednesday 21 October, near a three-week high, after RBA Deputy Governor Andrew Hauser said the inflation outlook looked "materially worse" (Reuters).

2. Swaps moved to about a 40% chance of a 25 basis-point hike to 4.85% at the 2–3 November meeting, from 30% at the start of the week (Reuters), while the New Zealand dollar slipped 0.1%.

3. A speech moves a currency through rate pricing, so check whether the move is specific to that currency and whether London (from 07:00 UTC) confirms it.

The development

The Australian dollar rose 0.1% to $0.7013 in Asian trade on Wednesday 21 October, just below Tuesday's high of $0.7017 and close to a three-week high (Reuters). The trigger was a Citi investment conference in Sydney, where Reserve Bank of Australia (RBA) Deputy Governor Andrew Hauser said the inflation outlook looked "materially worse" than the RBA projected in its August report. He also said he did not know whether a further rise in the 4.60% cash rate would be needed in November (Reuters; ABC News).

Pricing moved quickly. Reuters reported that swaps implied about a 40% chance of a 25 basis-point increase to 4.85% at the 2–3 November meeting, up from 30% at the start of the week. ABC News, citing LSEG data, put the probability at 42%, after it had dropped below 20% last week when unemployment reached a five-year high of 4.7%.

Market transmission

A central-bank speech has no immediate effect on supply and demand for a currency. It works by changing the expected path of the policy rate. Here three parts of the speech did that work. Hauser said higher oil prices had worsened the outlook, with Brent near $108 compared with $102 at the last meeting (Reuters). He said firms increasingly treat 3.0% to 3.5% inflation as normal (Dow Jones), which points to a risk to inflation expectations. And he set the choice as one between doing more against inflation and "hold our horses" to protect the labour market (Reuters).

The move was specific to the Australian dollar. The New Zealand dollar slipped 0.1% to $0.5677 and the dollar index was steady at 101.78 (Reuters), so the Aussie's gain did not reflect a broad weakening of the US dollar.

What to monitor next

• Whether London (from 07:00 UTC) extends the move, or whether UK CPI at 06:00 UTC takes over the dollar narrative.

• Australian third-quarter CPI, due next week, which Reuters says could show headline inflation near 4.0% with core near 3.5%.

• Brent, which Hauser named as a driver of the worse outlook.

• Changes in November hike pricing, which rose from below 20% to 42% within a week.

Reusable lesson

Before you explain a session move as the result of a speech, run three checks. First, did rate pricing move, and by how much? Second, is the currency rising against more than one counterpart? Third, did the official use new language or repeat known guidance? Hauser's comments pass the first two checks: pricing rose about ten points and the Aussie outperformed the kiwi. They partly pass the third, because the RBA had already said that inflation risks were on the upside.

Invalidation and risk

Hauser was explicit that the forecasts are not final, and he did not commit to a hike. A softer third-quarter CPI, a further rise in unemployment, or a fall in oil could reverse the repricing. The Aussie also remains sensitive to equity sentiment around technology earnings this week.
