## What is Currency?

Currency refers to a medium of exchange that is widely accepted within a specific country or region for conducting transactions. It serves as a standardized unit of value that people use to buy goods and services, settle debts, and conduct various financial transactions. Currency can exist in both physical form (such as coins and banknotes) and digital form (electronic or virtual currencies).

Key characteristics of currency include:

1. Medium of Exchange: Currency facilitates trade by providing a common measure of value that buyers and sellers can use to exchange goods and services.
2. Unit of Account: Currency provides a standard unit of measurement for pricing and recording economic transactions. Prices are denominated in the local currency.
3. Store of Value: People use currency to store value temporarily. They can hold onto currency and use it for future transactions or savings.
4. Legal Tender: Currency is issued and regulated by a government or central authority, making it the official means of payment within a particular jurisdiction. It is referred to as “legal tender,” which means it must be accepted for settling debts and transactions.

## All Formulae Related to Currency

1. Exchange Rate Formula:
• The exchange rate (ER) represents the value of one currency in terms of another currency.
• ER = Amount of One Currency / Amount of Another Currency
• For example, if 1 US dollar (USD) can be exchanged for 0.85 Euros (EUR), then the exchange rate would be ER = 1 USD / 0.85 EUR = 1.1765 USD/EUR.
2. Percentage Change in Exchange Rate:
• To calculate the percentage change in the exchange rate between two periods:
• Percentage Change = [(New Exchange Rate – Old Exchange Rate) / Old Exchange Rate] x 100
3. Cross Exchange Rate Formula:
• The cross exchange rate calculates the value of one currency in terms of a third currency, using two other exchange rates.
• Cross Rate = (Exchange Rate of Currency A / Exchange Rate of Currency B)
• For example, if you have the exchange rates EUR/USD and GBP/USD, you can calculate the EUR/GBP cross rate.
4. Currency Appreciation Formula:
• To calculate the percentage appreciation of a currency, you can use the following formula:
• Percentage Appreciation = [(New Exchange Rate – Old Exchange Rate) / Old Exchange Rate] x 100
• A positive percentage indicates appreciation.
5. Currency Depreciation Formula:
• To calculate the percentage depreciation of a currency, you can use the following formula:
• Percentage Depreciation = [(Old Exchange Rate – New Exchange Rate) / Old Exchange Rate] x 100
• A negative percentage indicates depreciation.
6. Real Exchange Rate Formula:
• The real exchange rate adjusts the nominal exchange rate for differences in price levels between two countries. It is calculated as follows:
• Real Exchange Rate = (Nominal Exchange Rate x Domestic Price Level) / Foreign Price Level
• Where the domestic price level and foreign price level are represented as indices (e.g., CPI or GDP deflator).
7. Interest Rate Parity (IRP) Formula:
• Interest rate parity is an equation that relates interest rates and exchange rates. The formula for IRP is as follows:
• Forward Exchange Rate = Spot Exchange Rate x [(1 + Interest Rate of Foreign Currency) / (1 + Interest Rate of Domestic Currency)]
8. Purchasing Power Parity (PPP) Formula:
• Purchasing Power Parity is an economic theory that suggests exchange rates should adjust to equalize the prices of a basket of goods in different countries. The formula for PPP is:
• Spot Exchange Rate = (Price Level in Foreign Country / Price Level in Domestic Country) x Exchange Rate at Equilibrium
