Quote Currency

The quote currency, also called the counter currency or price currency, is the second currency in a currency pair. It is the currency in which the value of one unit of the first currency, the base currency, is expressed. In the pair EUR/USD quoted at 1.0850, the euro is the base currency, the US dollar is the quote currency, and the price says that one euro costs 1.0850 US dollars.

Every exchange rate involves a base and a quote currency, whether it appears on a trading screen, a bank's rate sheet or a money transfer app. Knowing which is which matters because the same rate can be written two ways, and confusion over direction is a common source of pricing mistakes in foreign exchange markets, treasury operations and payments.

A currency quote takes the form base/quote = price. The general relationship is:

Here the rate is the number of quote currency units per one unit of base currency. Converting the other way divides by the rate:

For example, with GBP/USD at 1.2700, a company converting £10,000 receives $10{,}000 \times 1.2700 = 12{,}700$ US dollars. A traveller converting $500 into pounds at the same rate receives $500 \div 1.2700 \approx 393.70$ pounds. When the rate rises, the base currency has strengthened against the quote currency; when it falls, the base currency has weakened.

The interbank market follows long-standing conventions about which currency is placed first. The euro is normally the base against all other currencies. Sterling is the base against most currencies except the euro, so the market quotes EUR/GBP and GBP/USD. The Australian and New Zealand dollars are usually quoted as the base against the US dollar. Most other currencies, including the Japanese yen, the Swiss franc, the Canadian dollar and emerging market currencies, are quoted with the US dollar as the base, as in USD/JPY or USD/INR, so the local currency is the quote currency.

Retail and local conventions can differ. A bank in a given country often publishes rates as the number of local currency units per foreign unit, which is called a direct quotation from the local point of view, while an indirect quotation shows how much foreign currency one unit of local currency buys. Both describe the same price viewed from opposite sides.

Dealers quote two prices: a bid price at which they buy the base currency and an ask price at which they sell it. Both are expressed in the quote currency, and so is the gap between them, the bid-ask spread. If EUR/USD is quoted at 1.0848 bid and 1.0852 ask, the dealer's spread is 0.0004 US dollars per euro, which on a trade of one million euros equals 400 US dollars. Profit and loss on a currency position is likewise measured in the quote currency first and then converted into the trader's reporting currency if that is different.

In payments the same logic appears in the terms used for conversions. When a business sells goods priced in euros and is paid in another currency, the provider applies a rate between the two and a FX markup to the price. The direction of the rate decides whether the markup is added or subtracted, so payment platforms state which currency is fixed. For a cross-border transfer, the sender usually fixes the amount in their own currency and the receiving amount is calculated in the destination currency, or the reverse when the recipient must receive an exact sum.

Cross rates between two currencies that are both normally quoted against the dollar, such as EUR/JPY, are calculated through the dollar quotes. Multiplying EUR/USD by USD/JPY gives the number of yen per euro, with the yen as the quote currency of the resulting pair.

Mistakes with quote currencies usually come from inverting a rate without noticing. A treasury team that reads USD/CAD as dollars per Canadian dollar, rather than Canadian dollars per US dollar, will misprice a payment by the full difference between the rate and its reciprocal. Rounding conventions also differ: most pairs are priced to four decimal places, while pairs with the yen as quote currency are typically priced to two. Systems that handle FX spot transactions therefore store the pair, its direction and its precision explicitly rather than relying on a bare number.
