Producer prices rose 2.5% in a month while consumer prices fell 1%. That gap is your margin
The Ghana Statistical Service released the August Producer Price Index on Wednesday 16 September. Producer price inflation rose to 4.4% year on year from 4.0% in July, and month on month producer prices rose 2.5%, up from 2.0%. Mining and quarrying drove it, rising to 4.9% from 3.5% and contributing 2.1 percentage points of the headline rate on a 43.7% weight in the index. Within mining, crude oil and natural gas extraction recorded 12.9%. Industry excluding construction accelerated to 6.3% from 5.6%. Government Statistician Dr Alhassan Iddrisu described producer prices as an early warning system that signals cost pressure at the factory gate before it reaches retail.
Put the two August readings side by side and the picture is unambiguous. Producer prices rose 2.5% over the month. Consumer prices fell 1.0% over the same month. Those two numbers moving in opposite directions by three and a half percentage points is not a statistical curiosity. It is a measurement of where the cost increase is currently sitting, and the answer is that it is sitting on business margin, not on the customer.
Every Ghanaian business owner who has felt that the inflation headline does not match their experience now has the data explaining why. The 5.0% CPI figure describes what your customers pay. The 4.4% PPI figure, and specifically its 2.5% monthly acceleration, describes what you pay. For most of this year those two tracked loosely together. In August they separated.
The forward implication is the part to act on. Producer price pressure does not disappear. It either compresses margin until the business fails, or it passes through to consumer prices with a lag. Since the August data was collected, the fuel floors have risen roughly 10% for petrol and 7.5% for diesel, and the cedi has weakened about 4.12%. September producer prices will be worse, not better.
Service businesses, where producer inflation was the slowest of the three broad sectors at 1.8%. Businesses that already re-priced forward contracts. Firms with inventory bought at earlier prices. Suppliers of efficiency and cost-control services.
Manufacturers and processors absorbing 6.3% industrial producer inflation. Mining suppliers. Anyone on a fixed-price contract signed before August. Businesses that read the 5.0% CPI headline and assumed their own costs were rising at that rate.
Calculate your own input inflation this week and stop using the CPI headline as a proxy for it. Take your five largest input lines, price them today against what you paid in June, and work out the real percentage. For most manufacturers and processors that number will be closer to 6.3% than to 5.0%, and for anyone fuel-intensive it will be higher still. That figure, not the national headline, is what your pricing review should be built on. Then act on the Government Statistician's own advice: tighten cost control, review pricing deliberately, hold appropriate inventory of critical inputs, and diversify suppliers to reduce exposure to sudden increases.
