Citable research brief

Core conclusion · Tlines extraction

Westpac does not view the strong July CPI print as sufficient evidence to fully price in an RBA rate hike, maintaining that a November hike is plausible but not the base case.

Time horizon: 3 months · 6 months

Key arguments

The strong July monthly CPI raises the chance of a November RBA hike, but one data point is insufficient to lock in a hike.
The RBA has emphasized monthly data are noisy and seasonal patterns are unclear; new financial year re-pricing may moderate subsequent months.
Earlier data flow (labour market, wages, Q2 CPI) was softer than RBA forecasts, and resilient consumer spending is not read as upside inflation risk.
A November hike is more plausible than September given the timing of the August CPI release relative to the September meeting.
Split decisions are possible; some MPB members lean towards pre-emptive 'insurance' hikes, but others may dissent due to differing views on supply capacity.
Investors should allow for some risk of a hike later this year, but not fully price it in based on one CPI print.

Key numbers

Inflation above target range: half a percentage point
July CPI release: strong
Q2 CPI: softer than RBA forecast

Main risks

If the August CPI surprises on the downside or is moderate, a September hike could look premature.
A September hike would certainly involve dissents, and a November hike could also be split.
Fuel cost pass-through risks have faded, but other upside inflation risks may emerge.

Corresponding source evidence

The strong July monthly CPI does raise the chance of an RBA hike in November. But we do not think this one data point is enough to rush all the way to the other side of boat and lock in a hike. · 3 months
The timing of the September meeting is awkward for policymakers considering an early hike. The August CPI is released the following day. · 3 months
But one monthly CPI print is not enough evidence to price in a hike fully. · 6 months

Conditions / invalidation

if the strong CPI is confirmed by subsequent data
if the RBA raises the cash rate in the near term
