After all, the whole idea of currency works because people believe it will be worth something tomorrow. This is the confidence that allows currency to perform its functions as:

• Medium of exchange: used for the exchange of goods and services.
• A unit of account-a standard for pricing and measuring value
• A store of value: a means to save wealth over time.

Currency Exchange Rate — Definition & Example

A currency exchange rate tells you how much one currency is worth compared to another. For example, if 1 USD equals 80 INR, you require ₹80 to purchase $1.

Current exchange rates fluctuate and change according to many different variables, including:

• Supply and demand in global forex markets
• Differences in interest rates between countries
• Inflationary trends and economic stability
• Market confidence or sentiment towards a nation's economy

How Central Banks Manage Currency Value

But, really, underlying it all is currency stability, in which the leading role is played by central banks: the Reserve Bank of India, the European Central Bank, and their counterparts in other countries. The idea is to keep a tab on inflation, guard growth, and avoid wild swings in prices.

They manage currency value through:

• Setting interest rates to attract or reduce foreign capital
• Supply control by buying or selling foreign reserves
• Market interventions during periods of volatility

There are three main exchange rate systems:

1. Fixed rate — currency value is pegged to another, such as the US Dollar
2. Managed or pegged rate -central banks allow limited fluctuation
3. Floating rate —value is determined by market forces

Cryptocurrency vs. Fiat Currency

Fiat currency is government-issued money like USD or INR. A fiat currency relies solely on law and the policy of the central bank rather than any physical commodity like gold.

Cryptocurrency is digital and decentralized. It operates using blockchain technology, in which rules are coded and supply is limited.

Key differences include:

• Control: Fiat is controlled by central banks, while crypto is controlled by blockchain code.
• Stability: Fiat is normally stable, whereas crypto is generally volatile.
• Regulation: Fiat is heavily regulated, and crypto rules are still evolving.
• Use Case: The day-to-day payments are covered by Fiat; crypto is more for investment or digital assets.
