Currency Exchange Rates and Spreads
Written by OnlineLoan on 18:21Currency Exchange Rates and Spreads
Currency exchange rates are determined by the currency exchange market. (The currency exchange market is described further below.) A currency exchange rate is always quoted for a currency pair using ISO code abbreviations. For example, EUR/USD refers to the two currencies Euro (the European currency) and U.S. Dollar. The first is referred to as the base currency, while the second as the quote currency. The EUR/USD exchange rate specifies how many US Dollars you have to pay to buy one Euro, or conversely how many US Dollars you obtain when you sell one Euro. More generally, if buying, an exchange rate specifies how much you have to pay in the quote currency to obtain one unit of the base currency, and if selling, the exchange rate specifies how much you get in the quote currency when selling one unit of the base currency.
A currency exchange rate is typically given as a pair consisting of a bid price and an ask price. The ask price applies when buying a currency pair and represents what has to be paid in the quote currency to obtain one unit of the base currency. The bid price applies when selling and represents what will be obtained in the quote currency when selling one unit of the base currency. The bid price is always lower than the ask price.
In the currency market, the following abbreviation for the currency exchange rate pair is used:
The first component (before the slash) refers to the bid price (what you obtain in USD when you sell EUR), and in this case includes four digits after the decimal point. The second component (after the slash) is used to obtain the ask price (what you have to pay in USD if you buy EUR). The ask price is obtained by increasing the first component until the last two decimal places are equal to the digits in the second component. In this example, the ask price is 0.8428. As another example, 0.8498/03 refers to a bid price of 0.8498 and an ask price of 0.8503. (Note that for some exchange rates it is customary to quote rates in units of 100, as is the case with USD/JPY.)
The difference between the bid and the ask price is referred to as the spread. When trading large amounts of $1M or higher, the spread obtained in a quote is typically 5 basis points or PIPs, with each basis point referring to 0.0001 (or 0.01 when, say, the Yen is involved). In the example above, the spread is 0.0005 or 5 PIPs. When trading smaller amounts, the spread may be larger; for example, when trading less than $100,000, spreads of 50-200 PIPs are common. Credit card companies typically apply a spread of 200-300 PIPs. Banks and exchange bureaus typically use a spread in the range of 200-1000 PIPs (in addition to charging a commission). For investors and speculators, a lower spread translates into easier profit taking due to movements in exchange rates.
