# Currency

The Euro is the common currency of the member states of the European Union, and was introduced to Finland in 2002. Other important currencies include the US dollar the British pound and the Japanese yen. We convert currencies into other currencies using exchange rates.

When using exchange rates, an exchange transaction is always viewed in terms of what the bank (or other company specialising in currency exchange) does to the currency. Currency exchange always sells or buys foreign currency, not euros!

The buying rate is the rate at which the bank buys the currency. Tourists come to exchange currency, for example, dollars to euros.

The selling rate is the rate at which the bank sells currency. Now the traveller is going away on a trip and wants to exchange euros for dollars.

As a general rule:

the euro is converted into another currency by multiplying the euro amount by the exchange rate (selling rate)

the amount expressed in another currency is converted into euros by dividing by the exchange rate (purchase rate)

Use the following exchange rates for the following tasks.

Example 1. A tourist wants to exchange 350 euros for British pounds. How many pounds does a tourist receive?

The bank sells pounds to the tourist, so the selling rate is used.

Example 2. A tourist returns from a holiday trip to Denmark. He has 125 krones left in his wallet, which he wants to exchange for euros. How many euros does a tourist receive?

The bank buys the tourist krones, so the purchase rate is used.

Exchange rates are not fixed, so the value of the euro against other currencies changes daily. The value of a currency may fall or rise relative to other currencies. In this case, we are talking about strengthening the currency (revaluation) or weakening the currency (devaluation).

If the euro strengthens, you will receive more foreign currency with one euro.

If the euro weakens, you will receive less foreign currency with one euro.

Example 3. In June 2017, the dollar exchange rate against the euro was 1,0871. In June 2018, the corresponding rate was 1,1245.

a) Did the euro weaken or strengthen against the US dollar?

b) How much has the US dollar devalued over the same period?

Solution.

a) The amount of the strengthening or weakening of a currency is expressed as a percentage. So let's compare the ratio of courses. Remember that the original / previous value is the one being compared.

The exchange rate has increased and the euro has revalued 3,4%.

b) The dollar values must first be converted into euros.

June 2017:

So

June 2018:

As the dollar has weakened against the euro, the dollar has devalued.

The devaluation percentage

The dollar has devalued 3,3%.
