# Global Macro — China returns to expansion as Australian inflation reaccelerates

The highest-information change on 30 September is that yesterday's policy divergence is now visible in the data. China's official manufacturing PMI rose to 50.1 in September from 49.8 in August, returning above the expansion threshold, while the composite PMI output index rose to 50.7. Australia moved in the opposite inflation direction: consumer prices accelerated to 4.0% year on year in August from 3.5% in July, while trimmed-mean inflation remained at 3.6%. The Reserve Bank of Australia's 29 September rate increase therefore looks less like an isolated policy choice and more like a response to a domestic inflation constraint that is not easing as quickly as activity conditions would normally suggest.

The Chinese data do not show a broad boom. Production rose to 51.7 and new orders remained just above 50, but manufacturing employment fell to 48.4, small manufacturers remained below 50, and new orders in non-manufacturing activity were only 46.5. The rebound is therefore production-heavy and still incomplete on labour demand and parts of domestic demand. That distinction matters because targeted credit support can lift industrial activity without immediately restoring a self-sustaining private-demand cycle.

The United Kingdom adds a third configuration. The Office for National Statistics revised second-quarter GDP growth to 0.5% from 0.4%, with services and construction expanding while production contracted slightly. Real household disposable income per head also rose 1.0% after falling in the first quarter. The global regime is increasingly one of country-specific combinations of growth, inflation and policy rather than a synchronized tightening or easing cycle.

## China's PMI crossed 50, but production is stronger than employment

China's National Bureau of Statistics reported the manufacturing PMI at 50.1 in September, up 0.3 percentage point from August. The production index rose to 51.7, while new orders were 50.5. The composite PMI output index reached 50.7 and non-manufacturing business activity rose to 50.2.

The internal composition is less expansionary than the headline. Manufacturing employment fell to 48.4. Small manufacturers were at 48.9, compared with 50.6 for large firms. Non-manufacturing new orders were 46.5. Existing manufacturing orders were also weak at 46.0.

Crossing 50 matters because it ends two months below the official expansion threshold, but the mechanism is not uniform. Production has accelerated faster than employment and several demand indicators. That pattern is consistent with policy-supported industrial activity improving before household and labour-market conditions fully broaden.

Price indicators also strengthened. The manufacturing raw-material purchase-price index rose to 60.8 and the producer-price index to 54.0. These are diffusion indices rather than inflation rates, so they should not be read as percentage price changes. They nevertheless show that the industrial rebound is occurring with greater input-cost pressure.

## Australia's headline inflation accelerated while underlying inflation stayed sticky

The Australian Bureau of Statistics reported consumer prices 4.0% higher in August than a year earlier, up from 3.5% in July. The seasonally adjusted monthly CPI rose 0.7%, while the original monthly measure increased 0.4%. Trimmed-mean inflation remained at 3.6%.

Housing prices rose 5.7% over the year and transport prices 5.6%. The distinction between headline and underlying inflation is important. The acceleration in headline CPI does not show a fresh acceleration in trimmed-mean inflation, but underlying inflation also did not fall.

This gives more context to the RBA's decision one day earlier to raise the cash rate to 4.60%. The central bank is responding to an economy in which headline inflation has reaccelerated and the underlying measure remains above the midpoint of its target range, even as interest-sensitive areas such as housing finance face tighter conditions.

| New release | Latest reading | Previous/comparison | What changed |
|---|---:|---:|---|
| China manufacturing PMI | 50.1 | 49.8 in August | Returned to expansion |
| China composite PMI output | 50.7 | 49.5 in August | Broader output index moved above 50 |
| China manufacturing employment | 48.4 | 48.7 in August | Labour component weakened |
| Australia CPI, year on year | 4.0% | 3.5% in July | Headline inflation accelerated |
| Australia trimmed-mean inflation | 3.6% | 3.6% in July | Underlying inflation stayed sticky |
| UK Q2 real GDP, quarter on quarter | +0.5% | +0.4% previous estimate | Growth revised higher |

The table combines diffusion indices, inflation rates and GDP growth rates. The values are not comparable in level; the purpose is to show the direction of the new information released on 30 September.

## The UK revision adds resilience without creating a synchronized growth story

The Office for National Statistics revised UK real GDP growth in the second quarter to 0.5% quarter on quarter from the earlier estimate of 0.4%. First-quarter growth remained 0.6%. Services expanded 0.6% and construction 0.8%, while production fell 0.1%.

Real household disposable income per head increased 1.0% after a 0.8% decline in the first quarter, and the household saving ratio rose to 8.8%. GDP per head increased 0.5% on the quarter and 1.2% on the year.

The revision matters because it weakens a simple global slowdown narrative. The UK is showing more resilience than the previous estimate implied, but that does not mean a broad reacceleration is underway. The growth composition remains uneven and the stronger data arrive in a global environment where several central banks still face inflation constraints.

## The common mechanism is dispersion, not synchronized reflation

```flow
China: targeted credit support -> production PMI 51.7 -> composite output 50.7 -> employment 48.4 and non-manufacturing new orders 46.5 -> recovery broadens only partially
Australia: housing and transport inflation -> CPI 4.0% with trimmed mean 3.6% -> RBA tightening pressure remains -> domestic rate sensitivity rises
United Kingdom: Q2 GDP revised to +0.5% -> household income improves -> growth resilience increases -> less case for abrupt easing
Combined effect -> monetary and market pricing becomes more country-specific
```

Yesterday's policy split between Australia and China was visible in central-bank and credit instruments. Today's releases add a factual test of those policy choices. Australia has an inflation problem that remains persistent enough to justify tighter policy. China has activity returning above 50, but the recovery is not yet broad enough to remove the case for targeted support.

That combination has several cross-asset implications. Currency responses should increasingly reflect relative inflation and growth rather than a single global direction. Duration-sensitive assets face different domestic discount-rate paths. Commodity demand can benefit from stronger Chinese production while energy-linked inflation keeps pressure on importing economies. Credit transmission also becomes more local: the same global investor faces tighter Australian household conditions and targeted Chinese infrastructure support at the same time.

## Stronger Chinese output does not yet prove a durable demand recovery

The contrary evidence to a stronger China thesis is inside the same release. Employment remained below 50, small firms stayed in contraction, non-manufacturing new orders were weak and existing manufacturing orders were only 46.0. A production-led PMI improvement can fade if final demand and labour income do not broaden.

The contrary evidence to a worsening Australian inflation thesis is that trimmed-mean inflation did not accelerate in August. If headline inflation falls as energy and transport effects normalize while the underlying measure begins to decline, the current tightening pressure could prove temporary rather than the start of a new persistent inflation leg.

The UK revision is also backward-looking. A higher estimate for April-June does not establish the current-quarter path and should not be treated as evidence that high financing costs no longer matter.

## What would change the assessment

A broader Chinese recovery would require sustained manufacturing new orders above 50, stronger small-firm conditions, improving employment and better non-manufacturing demand. If those indicators remain weak, the September rebound should be treated as an industrial stabilization rather than a full domestic-demand recovery.

For Australia, the decisive next information is whether September headline and trimmed-mean inflation begin to fall after the RBA increase. A clear decline in underlying inflation would reduce the probability that today's 4.0% headline reading represents a durable second-round inflation process.

For the UK, the next question is whether services and household income resilience continue into the third quarter. The current data support resilience, not a conclusion that the economy has escaped the high-rate constraint.

The new global signal is that policy divergence is being validated by divergent macro data. China has crossed back into expansion but with incomplete demand breadth; Australia has reaccelerating headline inflation and sticky underlying pressure; the UK has stronger-than-estimated growth. Markets should therefore be read through country-specific transmission mechanisms rather than a single global cycle.
