Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Exchange Rate shopping experience:
1. Compare - without doubt the biggest advantage that the Exchange Rate offers shoppers today is the ability to compare thousands of Exchange Rate at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.
2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about
3. Testimonials - don't know anybody that has bought a Exchange Rate? Wrong! If the Exchange Rate is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.
4. Questions - Got a question about Exchange Rate then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....
5. Reputation - Never heard of the company selling Exchange Rate? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Exchange Rate and build up a picture of their reputation for sales, returns, customer service, delivery etc.
6. Returns - still worried that even after all of the above your Exchange Rate wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.
7. Feedback - happy with your Exchange Rate then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.
8. Security - check for the yellow padlock on the Exchange Rate site before you buy, and the s after http:/ /i.e. https:// = a secure site
9. Contact - got a question about Exchange Rate, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.
10. Payment - ready to pay for your Exchange Rate, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.
In
finance, the
exchange rate (also known as the
foreign-exchange rate,
forex rate or
FX rate) between two
currency specifies how much one currency is worth in terms of the other. For example an exchange rate of 123
Yen (JPY, ¥) to the United States dollar (USD, $) means that JPY 123 is worth the same as USD 1. The
foreign exchange market is one of the largest markets in the world. By some estimates, about 2 trillion USD worth of currency changes hands every day.
The
spot exchange rate refers to the current exchange rate. The
forward exchange rate refers to an exchange rate that is quoted and traded today but for delivery and payment on a specific future date.
Quotations
An exchange rate quotation is given by stating the number of units of a
price currency that can be bought in terms of 1
unit currency (also called
base currency). For example, in a quotation that says the EUR/USD exchange rate is 1.3 (USD per EUR), the price currency is USD and the unit currency is EUR.
Quotes using a country's home currency as the
price currency (e.g., 0.50593 = $1 in the UK) are known as
direct quotation or
price quotation (from that country's perspective) () and are used by most countries.
Quotes using a country's home currency as the
unit currency (e.g., $1.97656 = £1 in the UK) are known as
indirect quotation or
quantity quotation and are used in United Kingdom newspapers and are also common in Australia,
New Zealand and the Euro.
- direct quotation: 1 foreign currency unit = x home currency units
- indirect quotation: 1 home currency unit = x foreign currency units
Note that, using direct quotation, if the home currency is strengthening (i.e.,
appreciation, or becoming more valuable) then the exchange rate number decreases. Conversely if the foreign currency is strengthening, the exchange rate number increases and the home currency is depreciation.
When looking at a currency pair such as EUR/USD, many times the first component (EUR in this case) will be called the base currency. The second is called the counter currency.For example : EUR/USD = 1.33866, means EUR is the base and USD the counter, so 1 EUR = 1.33866 USD.
Currency pair are given with four decimal places, except
JPY with two decimal places (EUR/USD : 1.3386 - EUR/JPY : 165.29). In other words, quotes are given with 5 digits. Where rates are below 1, quotes frequently include 5 decimal places.
Free or pegged
If a currency is free-floating, its exchange rate is allowed to vary against that of other currencies and is determined by the market forces of supply and demand. Exchange rates for such currencies are likely to change almost constantly as quoted on financial markets, mainly by
banks, around the world. A movable or adjustable peg system is a system of fixed exchange rates, but with a provision for the devaluation of a currency. For example, between 1994 and 2005, the
Renminbi (RMB) was pegged to the United States dollar at RMB 8.2768 to $1. The Chinese were not the only country to do this; from the end of
World War II until
1970, Western European countries all maintained fixed exchange rates with the US dollar based on the
Bretton Woods system.
Nominal and real exchange rates
- The nominal exchange rate e is the price in domestic currency of one unit of a foreign currency.
- The real exchange rate (RER) is defined as RER = e (\frac{P^*}{P} ), where P is the domestic price level and P^* the foreign price level. P and P^* must have the same arbitrary value in some chosen base year. Hence in the base year, RER = e.
The RER is only a theoretical ideal. In practice, there are many foreign currencies and price level values to take into consideration. Correspondingly, the model calculations become increasingly more complex. Furthermore, the model is based on
purchasing power parity (PPP), which implies a constant RER. The empirical determination of a constant RER value could never be realised, due to limitations on data collection. PPP would imply that the RER is the rate at which an organization can trade goods and services of one economy (e.g. country) for those of another. For example, if the price of a good increases 10% in the UK, and the Japanese currency simultaneously appreciates 10% against the UK currency, then the price of the good remains constant for someone in Japan. The people in the UK, however, would still have to deal with the 10% increase in domestic prices. It is also worth mentioning that government-enacted
tariffs can affect the actual rate of exchange, helping to reduce price pressures. PPP appears to hold only in the long term (3–5 years) when prices eventually correct towards parity.
More recent approaches in modelling the RER employ a set of macroeconomic variables, such as relative productivity and the real interest rate differential.
N R_i = (R R_i + 1)(Expected \ inflation + 1) - 1
Interest rate parity
Interest rate parity (IRP) states that an appreciation or depreciation of one currency against another currency might be neutralized by a change in the interest rate differential. If US interest rates exceed Japanese interest rates then the US dollar should depreciate against the Japanese yen by an amount that prevents arbitrage. The future exchange rate is reflected into the forward exchange rate stated today. In our example, the forward exchange rate of the dollar is said to be at a discount because it buys fewer Japanese yen in the forward rate than it does in the
spot price. The yen is said to be at a premium.
IRP showed no proof of working after 1990s. Contrary to the theory, currencies with high interest rates characteristically appreciated rather than depreciated on the reward of the containment of
inflation and a higher yielding currency.
Balance of payments model
This model holds that a foreign exchange rate must be at its equilibrium level - the rate which produces a stable current account balance. A nation with a trade deficit will experience reduction in its
foreign exchange reserves which ultimately lowers (depreciates) the value of its currency. The cheaper currency renders the nation's goods (exports) more affordable in the global market place while making imports more expensive. After an intermediate period, imports are forced down and exports rise, thus stabilizing the trade balance and the currency towards equilibrium.
Like
purchasing power parity, the balance of payments model focuses largely on tradable goods and services, ignoring the increasing role of global capital flows. In other words, money is not only chasing goods and services, but to a larger extent, financial assets such as stocks and bonds. Their flows go into the
capital account item of the balance of payments, thus, balancing the deficit in the current account. The increase in capital flows has given rise to the asset market model.
Asset market model
The explosion in trading of financial assets (stocks and bonds) has reshaped the way analysts and traders look at currencies. Economic variables such as economic growth,
inflation and
productivity are no longer the only drivers of currency movements. The proportion of foreign exchange transactions stemming from cross border-trading of financial assets has dwarfed the extent of currency transactions generated from trading in goods and services.
The asset market approach views currencies as asset prices traded in an efficient financial market. Consequently, currencies are increasingly demonstrating a strong correlation with other markets, particularly equities.
Like the
stock exchange, money can be made or lost on the
foreign exchange market by investors and speculators buying and selling at the right times. Currencies can be traded at spot and foreign exchange options markets. The
wiktionary:spot market represents current exchange rates, whereas options are derivative (finance) of exchange rates.
Fluctuations in exchange rates
A market based exchange rate will change whenever the values of either of the two component currencies change. A currency will tend to become more valuable whenever demand for it is greater than the available supply. It will become less valuable whenever demand is less than available supply (this does not mean people no longer want money, it just means they prefer holding their wealth in some other form, possibly another currency).
Increased demand for a currency is due to either an increased transaction demand for money, or an increased speculative demand for money. The transaction demand for money is highly correlated to the country's level of business activity, gross domestic product (GDP), and employment levels. The more people there are out of work, the less the public as a whole will spend on goods and services. Central banks typically have little difficulty adjusting the available money supply to accommodate changes in the demand for money due to business transactions.
The speculative demand for money is much harder for a central bank to accommodate but they try to do this by adjusting
interest rates. An investor may choose to buy a currency if the return (that is the interest rate) is high enough. The higher a country's interest rates, the greater the demand for that currency. It has been argued that currency speculation can undermine real economic growth, in particular since large currency speculators may deliberately create downward pressure on a currency in order to force that central bank to sell their currency to keep it stable (once this happens, the speculator can buy the currency back from the bank at a lower price, close out their position, and thereby take a profit).
In choosing what type of asset to hold, people are also concerned that the asset will retain its value in the future. Most people will not be interested in a currency if they think it will devalue. A currency will tend to lose value, relative to other currencies, if the country's level of inflation is relatively higher, if the country's level of output is expected to decline, or if a country is troubled by political uncertainty. For example, when
Russian
President Vladimir Putin dismissed his Government on February 24, 2004, the price of the
Russian ruble dropped. When China announced plans for its first manned space mission, synthetic futures on Chinese yuan jumped (since China's currency is officially pegged, synthetic markets have emerged that can behave as if the yuan were floating).
Foreign exchange markets
The foreign exchange markets are usually highly
liquidity as the world's main international banks provide a market around-the-clock. The Bank for International Settlements reported that global foreign exchange market turnover daily averages in April was $650 1000000000 (number) in 1998 (at constant exchange rates) and increased to $1.9
1000000000000 (number) in 2004 ( Triennial Central Bank Survey of Foreign Exchange and Derivatives Market Activity 2004 - Final Results). The biggest foreign exchange trading centre is London, followed by New York and
Tokyo.
