What it means
Every currency quote pairs two currencies and the order is not decorative. The first currency listed is the base, and the price shown is always expressed in units of the second currency, which is the counter currency.
This determines which way a rising number is good news. If EUR/USD moves from 1.0850 to 1.1000, each euro now buys more dollars, so the base currency has strengthened and the counter currency has weakened against it.
Converting is simple once you know which side is which: multiply by the rate to go from base to counter, and divide by the rate to go the other way. Getting that backwards is one of the most common errors in finance teams that only occasionally handle foreign currency, and on a large invoice it produces a wildly wrong number rather than a small one.
Market convention fixes the order, so you cannot choose it to suit your spreadsheet. The euro, sterling, the Australian dollar and the New Zealand dollar are conventionally quoted as the base against the US dollar, while most other pairs put the dollar first, which makes the local currency the counter currency.
The counter currency also defines the unit in which a pip or tick is measured, and therefore the currency in which profit and loss on a position arises. A trade in USD/JPY produces gains and losses in yen, which then have to be translated back into the company's reporting currency before they reach the accounts.
In practice
Real-world examples.
Example
A German exporter invoices a US customer in dollars and books the receivable at an EUR/USD rate of 1.0850. Because the dollar is the counter currency, a rise in the quoted rate means each dollar received converts into fewer euros, so the finance team hedges the exposure with a forward contract.
Example
A treasury analyst is asked why the company's USD/JPY position shows a gain in yen rather than dollars. The answer is that the yen is the counter currency in that pair, so all price movement is expressed and settled in yen before being translated for reporting.
Example
A procurement manager reads a GBP/USD quote of 1.2600 and assumes it means one dollar buys 1.26 pounds. Sterling is the base and the dollar the counter currency, so the quote actually means one pound buys 1.26 dollars, and a purchase order priced on the wrong reading would be understated by more than a third.
Formula
Calculation
Amount in counter currency = Amount in base currency x quoted rate
Amount in base currency = Amount in counter currency / quoted rate
A UK subsidiary holds EUR 250,000 and needs to know the US dollar value at a quoted EUR/USD rate of 1.0850. Here the euro is the base currency and the dollar is the counter currency.
250,000 x 1.0850 = $271,250
Checking the reverse direction: 271,250 / 1.0850 = EUR 250,000, which confirms the conversion was done the right way round.
If the rate rises to 1.1000 before settlement, the same euro balance converts to 250,000 x 1.1000 = $275,000. That is $275,000 - $271,250 = $3,750 more of the counter currency for exactly the same amount of the base currency, because the euro strengthened against the dollar.Case study
Seen in the real world.
The following is an illustrative and entirely fictional scenario. Belmont Instruments, a mid-sized equipment maker, signed a EUR 4,000,000 supply contract with a European distributor while keeping its own books in US dollars. The contracts team recorded the deal using an EUR/USD rate of 1.0850, giving an expected receipt of 4,000,000 x 1.0850 = $4,340,000.
A junior analyst preparing the cash forecast divided instead of multiplied, entering 4,000,000 / 1.0850 = $3,686,636 and creating an apparent $653,364 hole in the quarter. The error survived two review meetings because nobody stopped to ask which currency was the counter currency.
The controller fixed the model and added a standing rule to the treasury policy: every conversion must show the pair, which side is the base and which is the counter, and a reverse check that returns the original amount. The rule cost nothing and has caught three similar slips since.
Watch out
Common mistakes.
- Reading the quote backwards and dividing when you should multiply, which produces an error large enough to distort a forecast rather than a rounding difference.
- Assuming a rising exchange rate is always favourable, when it depends entirely on whether you hold the base or the counter currency.
- Inventing your own quote order to suit a spreadsheet. Pair conventions are set by the market, and reversing them silently guarantees confusion later.
Questions
People also ask.
Is the counter currency the same as the quote currency?
Yes. Counter currency, quote currency and terms currency all describe the second currency in a pair, the one the price is expressed in.
Which currency does a pip movement belong to?
The counter currency, because the quoted price is denominated in it, so profit and loss on the position arises in that currency first.
How do I remember which is which?
Read the pair as a price tag: the base currency is the item being priced, and the counter currency is the money you pay with, so EUR/USD is the price of one euro in dollars.
