SunSalt Namibia and a Weaker Namibia Dollar
Walvis Bay, Namibia. SunSalt Namibia exports salt to South African buyers and imports solar-powered water pumps from China. Export contracts are priced in South African rand; import invoices are in US dollars. The Namibia dollar is pegged one-for-one to the rand. Over six months, the rand/US dollar rate moves from ZAR 17.00 to ZAR 19.20 per dollar. A pump that cost USD 4,000 now costs more in Namibia dollars, and the firm's annual import bill is USD 180,000. Its salt exports earn ZAR 5.2 million a year, unchanged in rand terms. Domestic costs such as wages, diesel and packaging are in Namibia dollars and have risen by 6%. Namibia's current account deficit is 5.1% of GDP, reserves cover 2.9 months of imports, and the government wants to reduce the deficit. The firm must decide whether to pass the cost increase on to South African customers, absorb it, or change suppliers.
1. Calculate the change in the Namibia-dollar cost of the annual import bill. Explain the effect on the firm's margin, given the peg and its rand export earnings.

At ZAR 17.00 per dollar, the annual import bill is USD 180,000 × 17.00 = N$3.06 million. At ZAR 19.20, it is USD 180,000 × 19.20 = N$3.456 million. The increase is N$396,000, or 12.9%.
The export side is the key point. SunSalt earns ZAR 5.2 million. Because the Namibia dollar is pegged one-for-one to the rand, that revenue remains N$5.2 million. The firm does not get the usual export boost from a weaker currency against its South African customers, because the rand has weakened along with the Namibia dollar. The depreciation is against the US dollar, the currency of its imports.
Before the change, export revenue less the import bill was N$5.2 million - N$3.06 million = N$2.14 million. After the change it is N$5.2 million - N$3.456 million = N$1.744 million, a fall of N$396,000. Domestic costs have also risen 6%, which adds further pressure. The margin is squeezed from both sides: import costs rise in Namibia dollars while export revenue stays flat in rand. The firm cannot rely on a weaker currency to raise export earnings; it must manage the cost side.
2. Explain whether the depreciation is likely to correct Namibia's current account deficit. Use the Marshall-Lerner condition, the J-curve and the structure of Namibia's trade.

A depreciation can improve the current account only if the Marshall-Lerner condition holds: the sum of the absolute price elasticities of export demand and import demand must exceed one. If demand is inelastic, a weaker currency raises the value of imports and may worsen the deficit.
Namibia's exports are concentrated in primary products such as minerals, fish and salt, often priced in foreign currency, and its imports include essential capital and consumer goods. These tend to have low elasticities in the short run. The J-curve therefore applies: the deficit may worsen first as import bills rise before volumes adjust, and improve only later if buyers respond.
There is a further limitation. Because the Namibia dollar is pegged to the rand, the depreciation is mainly against the US dollar and other currencies, not against South Africa, Namibia's largest trading partner. Trade with South Africa therefore sees little expenditure switching. Imported inflation may also raise domestic costs, offsetting any competitiveness gain.
With reserves at 2.9 months of imports, Namibia cannot rely on exchange-rate adjustment alone. The judgement is that depreciation is unlikely to correct a 5.1% deficit quickly. Supply-side policies to raise export capacity and reduce import dependence are more reliable, though slower.
3. Advise SunSalt on one financial and one operational response. Evaluate the risk attached to each.

A financial response is to hedge part of the US-dollar exposure with a forward contract. SunSalt could lock in a rate for, say, 60-70% of the USD 180,000 bill. That makes the Namibia-dollar cost predictable and protects the margin from further depreciation. The risk is two-sided: if the rand strengthens, the firm is locked into a worse rate than the market, and the hedge has an opportunity cost. There is also counterparty risk and a transaction cost.
An operational response is to renegotiate with the Chinese supplier or find a regional supplier invoiced in rand. This would remove the dollar exposure and may shorten lead times. The risk is higher unit cost, weaker warranty support, or lower quality. A local supplier may also lack the solar-pump range the customers want.
Passing the cost on is a third option, but salt is a relatively homogeneous product and South African buyers may switch. A partial pass-through, combined with the hedge, spreads the burden. The recommendation is to hedge the majority of the import bill, seek a rand-denominated supplier for a trial order, and pass on only the remaining cost increase after checking competitors' prices.
