China publishes a lot of economic data, and much of it gets less attention in London than it deserves. The monthly industrial profits report is one of the more useful releases because it shows not just whether factories are busy, but whether they are making money. This week’s figures, showing profits up 15.5 per cent in the first nine months of the year with high-tech manufacturing doing most of the work, are a good illustration of what it can tell you.

What the report measures

China’s National Bureau of Statistics publishes industrial profits for larger industrial firms, generally those with annual revenue above a set threshold. The data covers mining, manufacturing and utilities, and is usually reported as a year-to-date total with growth compared with the same period a year earlier, plus a figure for the latest month.

Because it is cumulative, the headline can hide changes in momentum. A strong year-to-date figure with a weak latest month means things are slowing. The reverse means they are speeding up.

Why profits tell you more than output

Industrial production tells you how much factories made. Profits tell you whether they could sell it at a decent price. If output is rising but profits are falling, firms may be cutting prices to shift goods, which points to weak demand and deflation pressure. If both are rising, demand is healthier. Our guide to China’s GDP figures covers the bigger growth picture.

Reading the sector detail

The breakdown by sector is often more revealing than the headline. In recent releases, electronics and high-tech manufacturing have been growing quickly on global demand for AI hardware, while industries tied to China’s domestic property market and household spending have struggled. That split is sometimes described as a two-speed economy: export-linked technology doing well, domestic demand still soft.

Profits are also affected by commodity prices. When oil and metal prices rise, mining and energy firms gain while manufacturers that buy those inputs see margins squeezed.

Why it matters for markets

For commodities, healthier Chinese factory profits can support demand for copper, iron ore and energy, because profitable firms are more likely to invest and expand. Our explainer on how copper prices link to global growth shows why.

For Asian shares, the report helps judge whether Chinese earnings can recover. For the Australian dollar, which is closely tied to Chinese demand for raw materials, it can be a useful signal. Our guide to AUD/USD explains that link.

It also feeds into expectations for policy. Weak profits tend to increase pressure on Beijing to add stimulus, while strong ones reduce the urgency.

Caveats to keep in mind

Chinese data can be revised and the sample of firms changes over time, which can distort year-on-year comparisons. One-off factors, such as the timing of holidays or big swings in commodity prices, can also flatter or depress a single month. It is best read alongside purchasing managers’ surveys, trade figures and producer prices rather than in isolation.

The beginner takeaway

China’s industrial profits report is a health check on the world’s biggest manufacturing base. Look at the latest month as well as the year-to-date figure, and pay attention to which sectors are driving it.
