Introduction
Coffee exported from Uganda is commonly sold in US dollars, while farmers, workers, transporters and many local suppliers are paid in Uganda shillings. The exporter must therefore convert between the two currencies.
This conversion can strengthen or weaken the Uganda-shilling value of coffee even when the international coffee price has not changed.
Understanding the Exchange Rate
The exchange rate shows how much of one currency can be exchanged for another. For Ugandan coffee, an important quotation is the number of Uganda shillings equivalent to one US dollar.
For example, when one dollar converts into more Uganda shillings than before, the dollar is said to have strengthened against the shilling, or the shilling has weakened against the dollar.
When one dollar converts into fewer Uganda shillings, the shilling has strengthened against the dollar.
A Simplified Coffee Conversion
A simple conversion can be shown as:
Uganda-shilling export value = US-dollar coffee value × Uganda shillings per US dollar
This calculation is only the starting point. Costs, differentials, outturn, financing and margins must still be considered before arriving at the local buying price.
Illustrative Example
Assume, for illustration only, that an exporter expects to receive US$100,000 from a coffee shipment.
| Illustrative exchange rate | Shilling value of US$100,000 |
|---|---|
| UGX 3,600 per US dollar | UGX 360,000,000 |
| UGX 3,800 per US dollar | UGX 380,000,000 |
| UGX 4,000 per US dollar | UGX 400,000,000 |
The dollar export value is unchanged, but the Uganda-shilling equivalent is different. This affects how much local currency is potentially available to cover coffee purchases and operating costs.
When a Weaker Shilling May Support Coffee Prices
When the Uganda shilling weakens against the dollar, each dollar earned from exports converts into more shillings.
This may:
- Increase the shilling value of export proceeds.
- Allow exporters to offer stronger local buying prices.
- Partly offset a decline in the international dollar price.
- Increase Uganda-shilling revenue reported by coffee businesses.
However, a weaker shilling can also increase the cost of imported fuel, fertilizers, machinery, spare parts and other inputs. The benefit to the coffee-selling price may therefore be accompanied by higher production and operating costs.
When a Stronger Shilling May Limit Local Prices
When the shilling strengthens, each dollar of export revenue converts into fewer Uganda shillings.
This may:
- Reduce the shilling equivalent of export income.
- Limit the price exporters can sustainably offer locally.
- Reduce the local benefit of a rising international coffee price.
- Make Uganda's coffee more expensive in certain commercial comparisons.
A stronger shilling may reduce the local cost of some imported inputs, although the effect depends on whether suppliers pass the currency benefit to farmers.
How Coffee Price and Exchange Rate Interact
| International coffee price | US dollar against Uganda shilling | Possible local effect |
|---|---|---|
| Rising | Dollar strengthening | Both factors may strongly support local prices |
| Rising | Dollar weakening | Exchange movement may reduce part of the benefit |
| Falling | Dollar strengthening | Currency movement may partly cushion the decline |
| Falling | Dollar weakening | Both factors may place pressure on local prices |
The actual result depends on the size of each movement and the exporter’s commercial position.
Why the Effect May Be Delayed
Farmers may observe a currency movement without seeing an immediate change in the local buying price.
This may occur because exporters:
- Sold the coffee earlier at an agreed exchange rate.
- Used a forward foreign-exchange contract.
- Are purchasing for an export contract priced previously.
- Hold dollar or shilling balances from earlier transactions.
- Have not yet adjusted local purchasing limits.
- Are managing stocks acquired at older prices.
The timing of the currency exposure matters as much as the current exchange rate shown in the news.
Currency Risk for Exporters
An exporter may buy coffee in Uganda shillings today but receive US dollars from the overseas buyer several weeks later.
If the exchange rate moves unfavourably during that period, the shilling value of the expected export proceeds may decline.
Exporters may manage this risk through:
- Forward foreign-exchange contracts.
- Matching dollar income with dollar expenses.
- Holding appropriate currency balances.
- Pricing local purchases conservatively.
- Aligning payment dates with expected receipts.
- Using financial institutions to manage currency exposure.
What Is a Forward Exchange Contract?
A forward exchange contract allows a business to agree in advance on an exchange rate for a future currency transaction.
For example, an exporter expecting to receive dollars later may agree with a bank on the rate at which those dollars will be converted into shillings.
This reduces uncertainty. However, if the future market rate turns out to be more favourable, the exporter may not receive that additional benefit because the rate was already fixed.
Exchange Rates and Farm Costs
Farmers should also consider how exchange rates affect production costs. A weaker shilling can increase the cost of imported:
- Fertilizers.
- Agrochemicals.
- Water pumps.
- Machinery.
- Fuel and lubricants.
- Packaging materials.
- Spare parts.
A higher coffee-selling price does not automatically mean that the farmer's profit margin has increased. Input costs may rise at the same time.
What Farmers Should Monitor
Useful information includes:
- International Robusta or Arabica price direction.
- The US dollar–Uganda shilling rate.
- Actual local buyer offers.
- Changes in fertilizer, fuel and transport costs.
- The farmer's production cost per kilogram.
Farmers should avoid using exchange-rate movements alone to predict the exact price a local buyer will offer.
How Coffee Planning & Analytics Can Help
The platform can support:
- Recording sales in Uganda shillings and US dollars.
- Recording the applicable exchange rate.
- Comparing international and local prices.
- Measuring the effect of exchange-rate scenarios.
- Tracking imported-input costs.
- Preparing budgets under different currency assumptions.
- Calculating profit after changes in both revenue and costs.
Conclusion
Exchange rates connect the international dollar value of coffee to the Uganda-shilling price seen by farmers and local businesses. A stronger dollar can increase the shilling value of export proceeds, while a stronger shilling can reduce it.
The final effect is influenced by the international coffee price, contract timing, currency hedging, local competition, production costs and the exporter's existing commitments.
