Difficulty: Introductory | Prerequisites: Basic arithmetic, familiarity with what an exchange rate is.
Foreign exchange sits at the heart of international business: any time a company earns revenue in one currency but pays costs in another, the exchange rate determines whether the deal is profitable. This topic falls within the Global Dimensions in Business course (INT-220) and connects directly to how firms manage cross-border transactions. You should already understand the basic idea that currencies have different values relative to one another and that those values shift over time. The scenarios here walk through a concrete case, converting Malaysian ringgit (MYR) to US dollars (USD), to show how even small rate movements can swing a deal from loss to profit.
A US-based company receives 1.25 million MYR from Malaysian sales and needs at least $90 USD per unit across 4,000 units to break even. At the current exchange rate of 3.52 MYR/USD, the conversion falls short and the company loses money. At a projected rate of 3.13 MYR/USD, the same revenue converts to $100 per unit and the company profits. A third option, keeping the MYR and buying raw materials in Malaysia, avoids the conversion entirely but introduces logistics costs.
Exchange rate
The price of one currency expressed in terms of another. For example, $1 USD = 3.52 MYR means one US dollar buys 3.52 Malaysian ringgit.
In simple terms, this is the "conversion price" between two currencies.
Malaysian ringgit (MYR)
The official currency of Malaysia, abbreviated MYR. In this scenario, it is the revenue currency.
Think of it as the money coming in from foreign sales before it gets converted.
Breakeven point (per unit)
The minimum revenue per unit a company must achieve to cover its costs, with zero profit and zero loss. Here, it is $90 USD per unit.
In simple terms, this is the price floor: anything below it means the company loses money on every unit.
Currency appreciation
When a currency increases in value relative to another. If the USD appreciates against the MYR, each dollar buys more ringgit.
Currency depreciation
When a currency decreases in value relative to another. If the USD depreciates against the MYR, each dollar buys fewer ringgit, and converting MYR back to USD yields more dollars.
In simple terms, a weaker dollar means your foreign-currency revenue is worth more when you convert it.
Forward rate / projected rate
An expected future exchange rate, often used for planning. In this case, the projected rate of 3.13 MYR/USD represents where the rate is expected to move by January 1st.
Think of it as a forecast of what the exchange rate will be at a future date.
A US-based company manufactures goods domestically
It sells products in Malaysia, earning 1.25 million MYR in revenue
The company produces 4,000 units
Breakeven price is $90 USD per unit (meaning the company needs at least $360,000 USD total to cover costs)
Conversion: 1,250,000 MYR / 3.52 = $355,114 USD
Per-unit revenue: $355,114 / 4,000 = approximately $89 USD
Result: $1 below the $90 breakeven, the company loses roughly $4,000 overall
The takeaway: a strong dollar (high MYR-per-dollar rate) hurts a company converting foreign revenue back into USD, because each ringgit is worth fewer dollars
Conversion: 1,250,000 MYR / 3.13 = $399,361 USD
Per-unit revenue: $399,361 / 4,000 = approximately $100 USD
Result: $10 above breakeven, the company earns roughly $36,000 profit
The takeaway: a weaker dollar (lower MYR-per-dollar rate) helps the company, because each ringgit converts to more dollars
Instead of converting to USD, the company keeps the 1.25 million MYR and uses it to buy raw materials locally in Malaysia
Advantage: avoids the unfavourable exchange rate entirely, and raw materials may be cheaper to source in Malaysia
Disadvantage: if manufacturing is in the US, those materials must be shipped internationally, adding logistics cost and complexity
Another consideration: sourcing and vetting Malaysian suppliers takes time away from production
The takeaway: keeping revenue in local currency can sidestep exchange rate risk, but it introduces supply chain and operational trade-offs
\text{USD received} = \frac{\text{Revenue in MYR}}{\text{Exchange rate (MYR per USD)}}\text{Per-unit revenue (USD)} = \frac{\text{USD received}}{\text{Number of units}}\text{Profit or loss per unit} = \text{Per-unit revenue} - \text{Breakeven price per unit}\text{Total profit or loss} = (\text{Per-unit revenue} - \text{Breakeven price}) \times \text{Number of units}Note: a higher exchange rate (more MYR per dollar) means each ringgit converts to fewer dollars, so USD received goes down. A lower exchange rate means each ringgit is worth more in dollar terms, so USD received goes up.
This is exactly the problem multinational companies face every quarter. A US exporter selling goods in Europe, Asia, or Latin America earns revenue in local currencies and must convert it back to dollars to pay American workers, suppliers, and shareholders. Companies like Apple, Procter & Gamble, and Caterpillar routinely report "currency headwinds" in their earnings calls, meaning unfavourable exchange rate shifts ate into their overseas profits.
It is also why many firms use hedging instruments, such as forward contracts or options, to lock in an exchange rate months in advance, removing the uncertainty from their revenue forecasts.
Students often think a "stronger dollar" is always good for US companies. It is not. A strong dollar hurts US exporters converting foreign revenue back to USD, because each unit of foreign currency buys fewer dollars.
Students sometimes confuse the direction of the exchange rate. When the quote is MYR/USD, a higher number means a stronger dollar and worse conversion for the company holding MYR. When the quote is USD/MYR, the logic reverses.
Keeping revenue in local currency (Scenario 3) is sometimes treated as a free solution. It avoids exchange rate risk, but introduces shipping, sourcing, and time costs that can exceed the currency loss.
Students occasionally assume the breakeven price is the same as the selling price. Breakeven is the cost floor. Any revenue above it is profit; any revenue below it is a loss.
Expect to be asked to calculate USD received from a foreign-currency revenue figure given an exchange rate. Know the formula cold.
Be ready to explain which direction an exchange rate movement helps or hurts a particular party (exporter vs importer).
Scenario comparison questions are likely: "which scenario is most profitable and why?" requires both the maths and the reasoning.
The trade-off in Scenario 3 (avoiding conversion vs incurring logistics costs) is the kind of qualitative analysis that shows up in short-answer or essay questions.
True or False: A higher MYR/USD exchange rate means the company receives more dollars when converting MYR to USD. (False: a higher rate means each MYR is worth fewer dollars.)
Fill in the blank: The breakeven price per unit in this scenario is ______ USD. (90)
True or False: In Scenario 2, the dollar has weakened relative to the ringgit compared to Scenario 1. (True: the rate dropped from 3.52 to 3.13 MYR per dollar.)
Fill in the blank: At a rate of 3.13 MYR/USD, 1.25 million MYR converts to approximately ______ USD. (399,361)
True or False: Scenario 3 eliminates all financial risk for the company. (False: it eliminates exchange rate risk but introduces shipping and sourcing costs.)
Q: A company earns 1.25 million MYR and the exchange rate is 3.52 MYR per USD. How much does the company receive in USD, and does it meet a breakeven of 90 USD per unit across 4,000 units?
A: 1,250,000 / 3.52 = 355,114 USD. Per unit: 355,114 / 4,000 = approximately 89 USD. This is 1 USD below breakeven, so the company loses roughly 4,000 USD.
Q: If the exchange rate shifts to 3.13 MYR per USD, what happens to the per-unit revenue and total profit?
A: 1,250,000 / 3.13 = 399,361 USD. Per unit: 399,361 / 4,000 = approximately 100 USD. The company earns 10 USD above breakeven per unit, for a total profit of roughly 36,000 USD (after accounting for the 360,000 USD cost base).
Q: Explain one advantage and one disadvantage of Scenario 3 (retaining MYR to purchase raw materials in Malaysia) compared to Scenario 1.
A: Advantage: the company avoids the unfavourable exchange rate entirely, keeping the full purchasing power of 1.25 million MYR in Malaysia. Disadvantage: since manufacturing is in the US, the raw materials must be shipped internationally, adding significant logistics costs that could offset or exceed the savings from avoiding conversion.
Q: Why does a weaker US dollar benefit a US company that earns revenue in a foreign currency?
A: When the dollar weakens, the MYR/USD rate falls (fewer ringgit per dollar). This means each ringgit converts to more dollars, so the same 1.25 million MYR yields a higher USD total. The company's foreign revenue becomes worth more in its home currency.
This connects to international trade theory because exchange rates directly affect comparative advantage and the profitability of exporting. It also ties into risk management: the scenarios illustrate why firms hedge currency exposure using forward contracts, futures, or options. If you are studying supply chain management elsewhere in the course, Scenario 3 is a natural bridge, since it shows how currency decisions interact with sourcing and logistics strategy.
