Repricing in shillings when inflation moves: a shop owner's guide

On 30 September 2026 the Uganda Bureau of Statistics reported that annual headline inflation for the twelve months to September was 4.6%, up from 4.1% in the year to August. For a shop owner that is not a headline to skim past: it is a prompt to check whether your shelf prices still cover your replacement costs. Here is how to read the release and what to do with it.

What moved in September

The UBOS publication breaks the headline into parts, and the parts matter more than the total:

• Core inflation (everything except food crops and energy) rose to 3.7% from 3.5%. Within it, other goods were at 3.1% and services at 4.6%.
• Food crops and related items jumped to 4.5% from 2.1% in a single month. UBOS attributes the rise to dry beans, milk, fresh cassava, sweet potatoes and green cabbage.
• Energy, fuel and utilities stayed high at 14.5%, from 14.3% in August.

So a restaurant, a school canteen or a grocery is feeling a very different September from a phone shop. Food inputs and fuel are where the pressure sits; most manufactured goods are moving more slowly.

What the central bank expects next

The Bank of Uganda held its Central Bank Rate at 9.75% on 13 August 2026, and at that meeting it projected core inflation to average between 4.0% and 4.5% over the next twelve months, with headline inflation expected between 5.5% and 6.0%. In February the Bank had projected 3.8% to 4.3% for 2026, so the outlook has firmed. The Governor's warning was that higher food, fuel and other input prices could still translate into broad-based inflation. Plan for prices to keep drifting up, not for a return to the 3% range.

Price from replacement cost, not from what you paid

The most common repricing mistake in a small shop is to mark up the price you paid for the stock on the shelf. In a rising market that stock will be replaced at a higher price, and the margin you thought you made is spent buying the next batch. Price from what the next delivery will cost. If your supplier has told you the next invoice is 5% higher, your shelf price should reflect that now, while you still have the cheaper stock to sell, not after.

A repricing routine that fits a month

1. Pull a margin report by item. You need cost, selling price and gross profit per product for the last 30 days. Sort by gross profit percentage, lowest first.
2. Match it to the CPI categories. Food and fuel-linked lines (cooking oil, flour, transport-heavy goods) are where September's pressure landed. Check those first.
3. Set a floor. Decide the minimum margin you will accept per category, and reprice everything below it. Round to the note or coin your customers actually carry: UGX 100 steps for small items, UGX 500 or UGX 1,000 for larger ones.
4. Leave the anchors. Every shop has a few items customers use to judge whether it is expensive. Hold those if you can and recover margin across the basket.
5. Change the price once, in one place. A till where products, prices and taxes come from one catalogue means the shelf label, the receipt and the report agree. Hand-edited prices on three devices do not.
6. Repeat on the day UBOS publishes. The CPI comes out at the end of each month. Put a recurring reminder next to it.

Watch services and wages too

The services component at 4.6% is a reminder that costs rise on the expense side as well as in the stock room: rent reviews, transport, security, cleaning. If you employ staff, their shopping basket is rising at the headline rate and wage conversations will follow. Build that into the margin floor rather than discovering it at year end.

Tell customers once, clearly

Customers accept price changes they can see the reason for. A small sign that says prices were updated this month because supplier costs rose, with a date, does more for trust than quietly changing labels. What customers resent is finding a different price at the till from the one on the shelf, which is a catalogue problem, not an inflation problem.

The number to track

Not the CPI. Your own gross margin percentage, by month, by category. If it is holding while UBOS reports 4.6%, your repricing is working. If it is slipping, the September release has told you exactly which shelves to walk first.
