What is the currency exchange rate?

What is the currency exchange rate

The international currency exchange rate is the rate at which one nation’s currency is interchanged for another. In simple terms, it is the rate at which two different currencies can be exchanged.

For instance, the lowest Value Of Paper Money Without The Portrait Of A U.S. President is $10. It has the portrait of Alexander Hamilton. Now, USD/JPY 109.67 means that for every US dollar, a business or an individual will receive 109,67 Japanese Yen.

In the international market, the exchange rates are analyzed by considering the currency values of all the countries. They change continuously based on a plethora of factors. In more explicit terms, they can be fixed to currencies of other countries.

The international currency exchange rates are a crucial factor in determining the economic health of a nation. It is one of the widely analyzed macro-environmental factors at a global level. The volatility of exchange rates affects global business entities that expand their operations across international boundaries.

Types of exchange rate

The three major categories of currency exchange rates are:

1. The fixed rate

the fixed rate

A fixed forex rate or pegged exchange rate is intended to value a currency that is pegged or constant against another currency. The most widely spread fixed rate system is the ‘Gold Standard.’

2. The pegged float

The pegged floating currencies are fixed to some value or band that are periodically adjusted or fixed. So basically, they are a hybrid of floating and fixed regimes.

3. The float


The floating currency exchange rate is also called a fluctuating exchange rate. The currency values in this system are allowed to fluctuate as per the foreign exchange markets and you must analyze them carefully to get best foreign exchange market rate.

How to determine currency exchange rates

There is no specific formula for the conversion of currencies. Markets decide the exchange rate by themselves. Almost all nations have a floating currency exchange. determinants of which are elaborated below:

Interest rates

interest rates

One of them is the upswing and downswing of interest rates in a country. When a country elevates its interest rates, there occurs a rapid flow of foreign investments.

This is because the international investors expect higher yields from the investments, for example, government bonds. A rise in the demand for investment leads to the augmentation in the need for domestic currency. As soon as the currency demand uplifts, the exchange rates strengthen.

Current account deficit

It balances a country’s payment to that of its trading partners. It implies that the government is importing a considerable amount of goods and the exports are relatively lesser. In order to make the payment for the imported goods, demands for foreign currencies uplift through depreciation in their own currency.

Public debt

public debt

Countries with more enormous public debts will attract lesser foreign investments, although public debt belongs to a nation’s internal affairs. Debt is a worrisome factor to national development and growth. Foreign investors become insecure to invest in such cases to the fear of lesser returns,

Expansionary monetary policy

The Expansionary monetary policy rapidly increases the money supply or decreases short-term interest rates. Keeping the other factors unchanged, a thrust in money supply causes demand for services and goods. This, in turn, results in a hike in the costs of those commodities, thereby causing inflation.

When inflation rises, the domestic currency value lowers. Therefore, a contraction in the supply of money can facilitate the currency value of a nation.

Geopolitical risks

If the government is not stable and faces frequent political chaos, the country’s exchange value is prone to fall. The nation would lag in the currency exchange rate index in comparison to the developed nations.


The determinants discussed above are essential to be adhered to by the emerging investors in the forex market. Due to its complicated nature, currency exchange is a matter of extensive research. In essence, it is all about staying updated from time to time.
