What it means
Each national currency has a code issued under an international standard (ISO 4217), which avoids confusion between currencies that share a name or symbol. The US dollar is USD, the euro is EUR, and the Peruvian sol is PEN.
Using the code rather than a local symbol makes amounts unambiguous in contracts and financial reports. The currency is issued by Peru's central bank, which also sets monetary policy.
It is a floating currency, so its value against the dollar moves with the market, although the central bank has at times bought and sold currency to smooth sharp swings. Many Peruvian businesses and households also use US dollars for large purchases, savings and some loans, so prices for property and cars are often quoted in dollars rather than PEN.
That dual use matters in finance. A company that earns revenue in soles but borrows in dollars faces currency mismatch risk, since a weaker sol makes the debt more expensive in local terms.
Treasury teams therefore track the PEN rate, hedge where they can and match the currency of income and debt. For foreign businesses, PEN comes into play when selling to Peruvian customers, paying local staff and suppliers, or valuing a subsidiary.
Under accounting rules, transactions in a foreign currency are translated at the rate on the transaction date, and balances are revalued at the period end. The differences create foreign exchange gains or losses in the accounts, and larger groups report the effect of translating a subsidiary's results into the parent's reporting currency.
Mining is a major part of Peru's economy, and commodity prices influence the demand for the currency. When export earnings rise, more foreign currency enters the country, which tends to support the sol.
When prices fall, the opposite can happen, so analysts watch metal prices alongside the exchange rate. A practical point is that exchange rates change constantly, so any rate should be taken from a live source on the day.
When preparing forecasts or contracts, finance teams often use a stated budget rate, and then compare actual results with it to measure the effect of currency movements.
In practice
Real-world examples.
Example
A US retailer buys textiles from a Peruvian supplier invoiced at PEN 150,000. At 3.75 PEN per $1 the cost is $40,000, and the finance team books a gain or loss if the rate changes before payment.
Example
A Lima-based company has a $2,000,000 loan from a foreign bank but earns its income in soles. Its treasurer buys a forward contract to fix the future exchange rate and protect repayments.
Example
A tourist agency in Cusco sets package prices in PEN and in dollars, because visitors from abroad prefer to see a price they can understand. It updates the dollar prices each month to reflect the current rate, so that its margins are stable.
Formula
Calculation
Amount in PEN = Amount in dollars x Exchange rate (PEN per $1)
For illustration, assume a rate of 3.75 PEN per $1. A US company invoices a Peruvian customer $10,000, which is 10,000 x 3.75 = PEN 37,500. If the sol weakens to 4.00 PEN per $1, the customer needs PEN 40,000 to pay the same $10,000, which is 2,500 more soles (40,000 - 37,500), or about 6.7% more (2,500 / 37,500). If instead the invoice is fixed at PEN 37,500, the US company receives 37,500 / 4.00 = $9,375 at the weaker rate, a loss of $625.Case study
Seen in the real world.
Andes Harvest is an illustrative, fictional exporter of fruit with its costs in Peruvian soles and sales in dollars. It budgeted a rate of 3.80 PEN per $1 for the year, expecting costs of PEN 19,000,000, or $5,000,000.
During the year, the sol strengthened to 3.50 PEN per $1, so the same PEN 19,000,000 of costs was worth 19,000,000 / 3.50 = about $5,428,571 in dollar terms. That is $428,571 more than planned, reducing the profit margin.
The finance director responded by hedging half of next year's expected costs, which is PEN 9,500,000, and renegotiating prices with buyers so that future contracts include a currency adjustment clause. The illustrative lesson is that a company with costs and revenue in different currencies must manage the PEN rate as an actual business risk.
Watch out
Common mistakes.
- Using an old exchange rate for budgets or invoices without checking the current PEN rate.
- Ignoring currency mismatch when borrowing in dollars against sol income.
- Confusing the currency code PEN with other uses of the same letters, when in finance it stands for the Peruvian sol.
