Australian GDP grew 0.4% — and a September rate rise went from a coin flip to 70%.

The call

GDP grew 0.4% in the June quarter. Expected 0.3%. Faster growth means more pressure on prices, and inflation is already above target at 3.6%. That pushes the RBA towards raising rates.

The rate is 4.35% today. A rise on 29 September moved from a coin flip to about 70%.

Higher rates make a currency worth more to hold. Good for the Aussie into 29 September.

The print

GDP 0.4% q/q, against 0.3% expected and 0.3% previously. GDP 2.1% y/y, against 1.8% expected. Household consumption 0.4%. Private business investment −0.5%. Saving ratio 6.5%, from 6.4%.

A one-tenth beat. The market treated it as much more than that.

Why it matters

The RBA does not set rates on GDP. It sets them on trimmed mean inflation, which is 3.6% and above the 2–3% target band. Growth matters through one question only: is demand running faster than the economy can supply?

That is where this print bites. Labour productivity was unchanged on the quarter, 0.2% lower on the year, and around 5% below its peak. Flat productivity means a low speed limit. When the speed limit is low, 0.4% does not have to be strong to be too fast.

The composition is poor and it does not rescue the doves. Business investment fell 0.5%. Non-mining profits fell 1.1% while mining profits rose 6.8%. Essential household spending fell 0.3%, and much of the consumption rise came from a 10.3% jump in vehicle purchases on the electric switch.

Subdued growth against a low speed limit still adds to inflation. That is why a one-tenth beat moved the market.

The case

Pricing for 29 September went from roughly 50% before the release to roughly 70% after it. The 10-year bond yield reached 5.19%, its highest since 2011. AUD/USD traded up through 0.7150.

The forecasters split on timing, not direction. IFM Investors put the move in "either September or November". Capital Economics said a hike is probably coming, "perhaps as soon as this month". CommBank keeps November as the base case while naming September as a live risk.

Nobody is arguing for a cut. Hold the Aussie into 29 September.

Ideas

AUD/NZD — the cleaner one. The RBNZ moved on 2 September and does not meet again until 28 October. Nothing is scheduled on the New Zealand leg before the RBA decides on 29 September, so the pair carries the Australian story on its own.

AUD/USD — live from 17 September, not before. The dollar has its own hawkish case. August payrolls came in at 162,000 against 56,000 expected, the previous two months were revised up by 55,000 combined, and September Fed hike odds are above 60%. US CPI lands 11 September and the Fed decides 15–16. Buying it before then is a bet on the Fed, not on this print. After the 16th there are thirteen clear days of Australian exposure into 29 September.

EUR/AUD and AUD/JPY — later. The ECB meets 10 September and the Bank of Japan 17–18.
