The Producer Price Index (PPI) also rose by 2.9% compared with August 2026. The report attributes the monthly increase to a 3.3% rise in manufacturing prices, which offset a 1.5% decline in mining prices.

Mining and quarrying prices increased by 56.9% year on year, while manufacturing prices rose by 21.2%. Electricity, gas, steam and air conditioning supply prices rose by 34.8% year on year and contributed 1.6 percentage points to the annual increase in the General PPI.

Manufacturing carries the largest weight in the overall index, at 872 out of 1,000.

Food manufacturing prices rose by 26.4% annually and 6.6% monthly, contributing 9.1 percentage points to the annual increase in the General PPI. Beverage prices increased by 25.8% year on year, while chemical and chemical product prices rose by 20.2%.

Chemical manufacturing recorded a sharp monthly increase of 8.7%, while prices of paper and paper products declined by 3.2% compared with August.

The PPI measures changes in prices received by domestic producers for goods and services. It covers mining, manufacturing and utilities, and tracks prices at the point where products leave the factory.

Domestic producer prices rise 22.2%

The Local Producer Price Index, which tracks prices for products sold on the domestic market, increased by 22.2% year on year and 3.2% month on month in September.

Manufacturing prices in this category rose by 24.4% annually and 3.5% monthly.

Food product prices recorded a 33.8% annual increase and a 7.2% monthly rise, contributing 11.0 percentage points to the annual increase in the Local PPI.

Beverage prices increased by 25.8% compared with September 2025, while chemical and chemical product prices rose by 21.7%.

Domestic producer prices increased faster than the overall index, on both an annual and a monthly basis, reflecting the sharp rise in manufacturing prices, particularly food products.

Mining drives export producer-price growth

The Export Producer Price Index increased by 17.3% year on year in September, although the monthly rise was more modest at 0.3%.

The annual increase was driven by mining prices, which rose by 56.9%. Manufacturing prices for exported products, however, declined by 14.1% over the same period.

On a monthly basis, manufacturing prices for exports increased by 2.1%, while mining prices fell by 1.5%.

Food product prices in the export manufacturing category declined by 16.7% year on year, while chemical and chemical product prices increased by 3.3%.

Higher mining prices supported the overall export index despite the decline in prices for manufactured exports.

The PPI measures the average change over time in the prices domestic producers receive for their goods, recorded at the point where products leave the factory. Because it captures prices at the start of the supply chain, economists and policymakers watch it as an early indication of cost pressures that can later feed into consumer prices.
