Long ago, people used to barter to exchange goods for other goods. As time goes by, instead of bartering, people use exchanging medium for trading since ithas an exact value and easier to carry around. Today, people use paper money as a medium of exchange. The paper money that we use today is called fiat money, it is the government-issued currency that is not backed by a physical commodity but by the stability of the issuing government. Since the government’s stability has an impact on the investment demand, the political change will affect the currency value. However, there are a number of reasons that can contribute the change in currency. This article will provide the causes and effects of the change in currency in a way that is easy to understand.
Currency appreciation is an increase in the value of currency comparing to another currency. There are number of reasons that contribute currency appreciation, including government policy, interest rates, trade balances and business cycles. Currency appreciation happens in a floating exchange rate system, so a currency appreciates when the value of one goes up compared to another. In other word, appreciation takes place when exchange rates change, allowing for the purchase of more units of a currency.
Currency depreciation is an opposite of currency appreciation, it is a fall in the value of a currency in a floating exchange rate system. Currency depreciation can occur due to any number of reasons – economic fundamentals, interest rate differentials, political instability, risk aversion among investors and so on.
Easy monetary policy and high inflation are two of the leading causes of currency depreciation. In a low interest-rate environment, hundreds of billions of dollars chase the highest yield. Expected interest rate differentials can trigger a bout of currency depreciation. While higher inflation is combated with central banks increasing interest rates, too much inflation is seen as a threat to stability, hence the likelihood of currency depreciation.
Additionally, inflation can lead to higher input costs for export which makes a nation’s exports less competitive in global markets, which will widen the trade deficit and cause the currency to depreciate.
Appreciation and depreciation of the currency can be very simple to identify. For example, USD/JPY = 100. The first of the two currencies (USD) is the base currency and represents a single unit, or the number 1 in the case of a fraction such as 1/100. The second is the quoted currency and is represented by the rate as the amount of that currency needed to equal one unit of the base currency. The way this quote reads is: One U.S. dollar buys 100 units of Japanese yen.
For the purposes of currency appreciation, the rate directly corresponds to the base currency. For example, If the rate increases to 110, then one U.S. dollar now buys 110 units of Japanese yen and if the currency depreciate that means one U.S. dollar can only buy Japanese yen in the value of less than 100. Therefore, the currency depreciation and appreciation can have a part in contributing exports and imports.
Since the exchange rate has an effect on the trade surplus or deficit, a weaker domestic currency stimulates exports and makes imports more expensive. Conversely, a strong domestic currency hampers exports and makes imports cheaper.
The example to illustrate this concept is, for example, an electronic component priced at $10 in the U.S. that will be exported to India. Assume the exchange rate is 50 rupees to the U.S. dollar. Ignoring shipping and other transaction costs such as import duties for the moment, the $10 item would cost the Indian importer 500 rupees. Now, if the dollar strengthens against the Indian rupee to a level of 55, assuming that the U.S. exporter leaves the $10 price for the component unchanged, its price would increase to 550 rupees ($10 x 55) for the Indian importer. This may force the Indian importer to look for cheaper components from other locations. The 10% appreciation in the dollar versus the rupee has thus diminished the U.S. exporter’s competitiveness in the Indian market.
To conclude, when a country has stronger value of currency or appreciation, they can import more goods and services from another country (assuming that the currency of exporting country remains the same.) than what they used to. And in the opposite way, if depreciation occurs in a country,no matter what the reason is, the number of product that they used to buy will be lesser in the same amount of money.
