Exchange rates play a vital role in international trade and investment, as they determine the value of one country’s currency relative to another. Two commonly used measures of exchange rates are the nominal effective exchange rate (NEER) and the real effective exchange rate (REER). While both are important in understanding and analyzing exchange rates, they have distinct differences that can impact their interpretation and use. This article aims to provide a comprehensive overview of NEER and REER, including their definitions, calculation methods, advantages and limitations, key differences, factors affecting exchange rates, and applications in international trade and investment. By the end of this article, readers should have a better understanding of how NEER and REER work, and how they can be used to inform investment and policy decisions.
Introduction to Exchange Rates
Definition of Exchange Rates
Exchange rate refers to the value of one currency in relation to another. It is the rate at which one currency can be exchanged for another. Exchange rates play a significant role in international trade, investment, and the economy of a country.
Types of Exchange Rates
There are two types of exchange rates – fixed and floating. In the fixed exchange rate system, the value of a currency is fixed against another currency or group of currencies. On the other hand, in the floating exchange rate system, the value of a currency is determined by the market forces of supply and demand.
What is Nominal Effective Exchange Rate (NEER)?
Definition of Nominal Effective Exchange Rate
Nominal Effective Exchange Rate (NEER) is the weighted average of a country’s exchange rate against the currencies of its trading partners. It is the value of a currency in relation to other currencies, without adjusting for inflation.
Calculation of NEER
NEER is calculated by multiplying the exchange rate of a country’s currency against its trading partners’ currencies by the weights assigned to each currency. The weights are usually based on the share of each currency in the country’s international trade.
Advantages and Limitations of NEER
The advantage of NEER is that it gives a comprehensive measure of a country’s currency value against its trading partners. However, it does not take into account the impact of inflation on the currency value. Therefore, it may not reflect the true value of a country’s currency.
What is Real Effective Exchange Rate (REER)?
Definition of Real Effective Exchange Rate
Real Effective Exchange Rate (REER) is the weighted average of a country’s exchange rate against the currencies of its trading partners, adjusted for inflation. It is the value of a country’s currency in relation to other currencies, accounting for the difference in the inflation rates.
Calculation of REER
REER is calculated by multiplying the NEER by the ratio of the domestic price level to the foreign price level. The domestic price level is usually represented by the Consumer Price Index (CPI).
Advantages and Limitations of REER
The advantage of REER is that it provides a more accurate measure of a country’s currency value, as it adjusts for inflation. However, it may not fully capture the impact of non-tradable goods and services on the currency value.
Key Differences between NEER and REER
Definition of Key Differences
The key difference between NEER and REER is that NEER does not adjust for inflation, while REER does. NEER provides a measure of a country’s currency value in relation to its trading partners’ currencies, while REER provides a measure of a country’s currency value adjusted for inflation.
NEER vs REER: Calculation Method
NEER is calculated by multiplying the exchange rate of a country’s currency against its trading partners’ currencies by the weights assigned to each currency. On the other hand, REER is calculated by adjusting the NEER for inflation.
NEER vs REER: Factors Considered
NEER considers only the exchange rates of a country’s trading partners’ currencies. In contrast, REER takes into account both the exchange rates and inflation rates of the trading partners’ currencies.
NEER vs REER: Interpretation and Use
NEER is used to assess a country’s competitiveness in international trade, while REER is used to evaluate a country’s external balance and exchange rate policy. NEER does not provide an accurate reflection of a country’s currency value, while REER provides a more accurate measure by adjusting for inflation.
Importance and Significance of NEER and REER
NEER and REER are important measures used to assess the competitiveness of a country’s currency in the international market. These measures allow us to estimate whether a country’s currency is overvalued or undervalued compared to other currencies.
Role of NEER and REER in International Trade and Investment
NEER and REER play a crucial role in determining trade competitiveness. They help investors and businesses assess the relative strength of a country’s currency against its trading partners. An overvalued currency can make exports more expensive and imports cheaper, leading to a trade deficit. On the other hand, an undervalued currency can make exports cheaper and imports more expensive, leading to a trade surplus.
Impact of NEER and REER on Macroeconomic Indicators
Changes in NEER and REER have a significant impact on various macroeconomic indicators such as inflation, growth, and employment rates. An overvalued currency can lead to lower export earnings, which can in turn impact GDP growth and lead to higher unemployment. In contrast, an undervalued currency can boost exports, increase GDP growth, and reduce unemployment rates.
Policy Implications of NEER and REER
Governments can use NEER and REER as policy tools to manage their currency’s value in the international market. Central banks can use monetary policy tools such as interest rate adjustments to influence their currency’s value and maintain its competitiveness in the global market.
Factors Affecting Nominal and Real Effective Exchange Rates
Definition of Factors Affecting Exchange Rates
Exchange rates are influenced by several factors, including monetary, economic, and political factors.
Monetary Factors
Monetary factors such as interest rates, money supply, and inflation can impact exchange rates. Higher interest rates can make a currency more attractive to investors, leading to an increase in demand and value.
Economic Factors
Economic factors, such as economic growth, trade balance, and productivity, can influence exchange rates. Countries with strong economic fundamentals tend to have stronger currencies, as they are seen as more attractive investment destinations.
Political Factors
Political factors such as geopolitical tensions, government stability, and policy changes can impact exchange rates. Uncertainty and instability can cause investors to pull out of a country’s markets and lead to a decline in currency value.
Applications of NEER and REER in International Trade and Investment
NEER and REER in Trade Competitiveness
NEER and REER are crucial in determining a country’s trade competitiveness. An overvalued currency can make exports more expensive, leading to a loss of competitiveness in the global market.
NEER and REER in Investment Decisions
Investors often use NEER and REER as a key factor when making investment decisions. They use it to assess the potential returns and risks associated with investing in a particular country or market.
NEER and REER in Foreign Exchange Reserves Management
Governments use NEER and REER when managing their foreign exchange reserves. Maintaining competitive exchange rates helps ensure that foreign exchange reserves are used effectively to maintain currency stability and economic growth.

Frequently Asked Questions
What is the difference between nominal and real exchange rates?
Nominal exchange rates refer to the price of one currency in terms of another, while real exchange rates adjust for differences in inflation rates between the two countries. Real exchange rates provide a more accurate picture of trade competitiveness by taking into account changes in relative prices.
What factors influence exchange rates?
Exchange rates are affected by a wide range of factors including monetary policy, economic growth, inflation, political stability, and global economic conditions. The relative strength of these factors can vary depending on the country and its specific circumstances.
How are NEER and REER used in investment decisions?
Investors generlly use NEER and REER to assess a country’s currency value and its potential for appreciation or depreciation.
A higher NEER or REER value suggests that the currency is overvalued, while a lower value implies that it is undervalued. Investors use this information to make investment decisions, such as whether to purchase or sell foreign currency or invest in international stocks.
What policy decisions can be informed by NEER and REER?
Policy makers use NEER and REER to formulate monetary and fiscal policies that can affect exchange rates.
For example, if a country’s NEER or REER is too high, policy makers can take measures to devalue the currency, such as lowering interest rates or increasing government spending. Conversely, if the currency is undervalued, policy makers can take steps to increase its value by raising interest rates or implementing austerity measures.
