The Price Was Fixed. The Currency Was Not.

A commodity trader based in Turkey bought chrome ore from a domestic mine at a price denominated in Turkish lira. The trader sold the chrome ore FOB Mersin to a Chinese buyer at a price denominated in US dollars. The trade margin — calculated at the exchange rate on the day the contracts were signed — was approximately $11 per MT, or $220,000 on 20,000 MT.
Between the date of contract and the date of payment — a period of approximately 8 weeks — the Turkish lira depreciated by 9% against the US dollar. The trader's purchase cost in lira remained fixed. The trader's sale revenue in dollars remained fixed. But the trader's operating costs — port handling, trucking, inspection, office overhead — were denominated in lira. As the lira weakened, those costs became cheaper in dollar terms. The depreciation actually improved the trader's margin on this particular trade.
But the reverse scenario is equally common and more damaging. If the trader had bought in USD (from a foreign supplier) and sold in a weakening local currency, or if the trader's purchase price was indexed to the USD and the lira strengthened, the margin would have been compressed or eliminated. Currency movement in either direction changes the economics of trades where the purchase and sale are not denominated in the same currency.
The Commodity Is Priced in Dollars. The Business Runs in Local Currency.
International commodity trade is predominantly denominated in US dollars. Commodity benchmarks — LME, ICE, CBOT, Platts — quote in dollars. International sales contracts use dollar pricing. Banks extend trade finance in dollars. But commodity traders based outside the US — in Turkey, India, Brazil, Indonesia, South Africa — incur significant costs in local currency: mine-gate purchase prices (often in local currency), inland logistics, port handling, office rental, staff salaries, legal fees, and government taxes and duties.
The FX exposure emerges from the mismatch between dollar-denominated revenue and local-currency-denominated costs. If the local currency weakens against the dollar, the trader's local costs become cheaper in dollar terms, improving the margin. If the local currency strengthens, the costs increase in dollar terms, compressing the margin. For a trader with a $220,000 margin on a trade, a 5% movement in the exchange rate can shift the margin by $50,000 to $100,000 depending on the proportion of costs denominated in local currency.
Industry estimates suggest that for commodity traders in emerging markets, 30 to 60% of total trade costs are denominated in local currency. On a trade with $2 million in total costs, $600,000 to $1.2 million is exposed to FX movement. A 10% currency move — not unusual in Turkish lira, Brazilian real, or Indonesian rupiah over an 8-week trade cycle — can shift costs by $60,000 to $120,000. On a trade with a $220,000 margin, this FX exposure represents 27 to 55% of the planned profit.
The critical operational judgment for traders with significant local currency costs is to quantify the FX exposure on each trade and decide whether to hedge it. FX hedging instruments — forward contracts, options — are available for most major emerging market currencies. The cost of an 8-week FX forward for a $1 million notional in Turkish lira is typically 1 to 3% annualized, or roughly 0.15 to 0.5% for the 8-week period. On $1 million, that is $1,500 to $5,000 — a modest cost relative to the $60,000 to $120,000 exposure it covers.
The Margin Calculation Must Include Currency, Not Just Commodity Price
The traders who manage FX risk effectively treat the exchange rate as a variable input in their margin calculation, not as a fixed assumption. When they calculate the trade margin, they model three scenarios: the margin at the current exchange rate, the margin if the local currency strengthens by 5-10%, and the margin if the local currency weakens by 5-10%. If the trade is unprofitable in the adverse scenario and the trader cannot hedge the FX exposure, the trade may not be worth doing.
The traders who do not model FX risk treat the exchange rate on the day of contract as a constant. They calculate the margin once and carry that number through the trade. When the final P&L arrives and the margin is 30% different from the projection — higher or lower — they attribute the variance to "currency movement" without recognizing that the movement was a predictable variable that could have been modeled and managed.
The chrome ore trader in Turkey benefited from lira weakness on this trade. On the next trade — when the lira temporarily strengthened after a central bank rate decision — the margin was compressed by approximately $45,000. Over a year of trading, the FX movements roughly cancelled out — some trades gained from lira weakness, others lost from lira strength. The net FX effect over 12 months was approximately a $30,000 loss — modest in aggregate but unpredictable on a trade-by-trade basis.
The traders who hedge FX exposure sacrifice the upside of favorable currency movements in exchange for eliminating the downside of adverse movements. They lock in a known exchange rate and calculate a known margin. The margin may be lower than the best-case scenario, but it is also higher than the worst-case scenario. For a business built on thin margins — 1 to 3% of cargo value — eliminating a variable that can swing the margin by 27 to 55% is not a cost. It is a structural requirement for predictable profitability.
The commodity price was hedged. The freight was fixed. The quality was within spec. The FX rate moved, and the margin moved with it. The traders who noticed are the ones who included currency in their risk model. The traders who did not notice — until the annual P&L showed margins thinner than trade-by-trade calculations predicted — are the ones who assumed that a dollar-priced commodity business operating with lira costs was a dollar business. It is not. It is a two-currency business, and the second currency has a voice in the margin even when the trader is not listening.
