3 Types of Exchange Rate Policies

Since the exchange rate contributes massively to the economy, both governments and central banks must have a policy for the exchange rate.

The three policies that we will be looking at are:
  1. Flexible exchange rate
  2. Fixed exchange rate
  3. Crawling peg


Flexible Exchange Rate

Flexible Exchange Rate: the exchange rate determined by the demand and supply in the foreign exchange market and has no direct intervention by the government or central bank.

However, the central bank can indirectly intervene by doing one of the two examples:
  1. Increase interest rate   \, →  \, Demand for US dollars  ↑  \, \uparrow \, →  \, Supply for US dollars  ↓  \, \downarrow \, →  \, exchange rate  ↑ \, \uparrow .
  2. Decrease interest rate   \, →  \, Demand for US dollars  ↓  \, \downarrow \, →  \, Supply for US dollars  ↑  \, \uparrow \, →  \, exchange rate  ↓ \, \downarrow .

Though the central bank can change the interest rate to change exchange rate, that is not their purpose in a flexible exchange rate regime. When they change their interest rate, it is mainly due to changing a monetary policy objective.


Fixed Exchange Rate

Fixed Exchange Rate: an exchange rate determined by the government or central bank and can be attained by blocking the forces of demand and supply in the foreign exchange market.

The fixed exchange rate is what the central bank wants.

Note: In order to attain a fixed exchange rate, there must be intervention by the government or central bank.

To keep a fixed exchange rate, the central bank/government must do the following:
  1. If exchange rate rises above the target value, then they sell US dollars.
  2. If exchange rate falls below the target value, then they buy US dollars.


Note: The Fed has no limit to how much US dollars they can sell, but they have a limit to how much US dollars they can buy.

This is because the Fed can create any quantity of US dollars it chooses but buying US dollars requires the Fed to sell foreign currencies which they have a limited amount of.

Suppose the targeted fixed exchange rate is 4 Yuan’s per US dollar for the central bank.

Exchange Rate Policy


There are four cases of the central bank keeping its fixed exchange rate.

Case 1: The demand for US dollars increases temporarily, so the demand for US dollars shifts from D0D_{0} to D1D_{1} . In this case, the Fed would sell 0.4 trillion US dollars to stop the exchange rate from increasing.

Exchange Rate Policy


This keeps the fixed exchange rate as 4.

Case 2: The demand for US dollars decreases temporarily, so the demand for US dollars shifts from D0D_{0} to D1D_{1} . In this case, the Fed would buy 0.4 trillion US dollars to stop the exchange rate from decreasing.

Exchange Rate Policy


This keeps the fixed exchange rate as 4.

Case 3: The demand for US dollars increases permanently, so the demand for US dollars shifts from D0D_{0} to D1D_{1} . In this case, the Fed would have to sell 0.4 trillion US dollars every day to stop the exchange rate from increasing.

Exchange Rate Policy


Selling US dollars every day means they must buy foreign currency every day. At some point, they must stop piling up foreign currency reserves, which means abandoning the fixed exchange rate.

Case 4: The demand for US dollars decreases permanently, so the demand for US dollars shifts from D0D_{0} to D1D_{1} . In this case, the Fed would have to buy 0.4 trillion US dollars every day to stop the exchange rate from decreasing.

Exchange Rate Policy


Buying US dollars every day means they must sell foreign currency every day. At some point, the Fed will run out of foreign currencies to sell, so they would have to abandon the fixed exchange rate.


Crawling Peg

Crawling Peg: an exchange rate regime like that of the fixed exchange rate, except it allows gradual depreciation or appreciation of an exchange rate.

The targeted exchange rate can change daily, weekly, monthly, or even at random time intervals.

The system is designed to “glide” in response to market uncertainties or inflation, and to minimize major economic dislocation.

Introduction to Exchange Rate Policy

Exchange rate policy plays a crucial role in shaping a country's economic landscape. It refers to the approach governments and central banks take in managing their currency's value relative to other currencies. This policy significantly impacts international trade, investment flows, and overall economic stability. The accompanying introduction video provides valuable insights into the three main types of exchange rate policies: flexible exchange rate, fixed exchange rate, and crawling pegs. A flexible exchange rate allows the currency's value to fluctuate based on market forces, while a fixed exchange rate maintains a constant value against another currency or basket of currencies. Crawling pegs represent a middle ground, allowing for gradual, controlled adjustments. Understanding these policies is essential for policymakers, businesses, and investors alike, as they influence everything from import/export competitiveness to inflation rates and foreign investment attractiveness. The video serves as an excellent starting point for grasping the complexities and implications of exchange rate policies in today's interconnected global economy.

FAQs

  1. What are the main types of exchange rate policies?

    The three main types of exchange rate policies are flexible exchange rates, fixed exchange rates, and crawling pegs. Flexible exchange rates allow currency values to fluctuate based on market forces. Fixed exchange rates maintain a constant value against another currency or basket of currencies. Crawling pegs allow for gradual, controlled adjustments to the exchange rate over time.

  2. How does a flexible exchange rate system work?

    In a flexible exchange rate system, the value of a currency is determined by supply and demand in the foreign exchange market. Governments and central banks do not directly set the exchange rate but can influence it through monetary policies such as adjusting interest rates. This system allows for automatic adjustment to economic shocks and changes in international competitiveness.

  3. What are the advantages and disadvantages of a fixed exchange rate system?

    Advantages of a fixed exchange rate system include stability and predictability in international trade and investment, potential control over inflation, and reduced exchange rate risk. Disadvantages include limited monetary policy independence, vulnerability to speculative attacks, and the need for significant foreign currency reserves to maintain the fixed rate.

  4. How does a crawling peg exchange rate system differ from fixed and flexible systems?

    A crawling peg system is a hybrid approach that allows for small, regular adjustments to the exchange rate, typically announced by the central bank. This system aims to combine the stability of fixed rates with some flexibility to adapt to changing economic conditions. It provides more predictability than flexible rates while allowing gradual adjustments to prevent large, sudden changes in the exchange rate.

  5. How do exchange rate policies impact international trade?

    Exchange rate policies significantly influence international trade by affecting export competitiveness, import costs, trade balances, and foreign investment. Fixed rates can provide stability for trade but may lead to imbalances if not reflecting economic fundamentals. Flexible rates allow for automatic adjustments in trade balances but can introduce volatility. The choice of policy can impact a country's economic growth, inflation rates, and overall position in the global marketplace.

Prerequisites

Understanding exchange rate policy requires a solid foundation in various economic concepts. While there are no specific prerequisite topics provided for this subject, it's crucial to recognize that a comprehensive grasp of fundamental economic principles is essential for mastering exchange rate policy. These underlying concepts form the backbone of international finance and monetary policy, enabling students to navigate the complexities of global currency markets and their impact on national economies.

Exchange rate policy is a multifaceted subject that intersects with numerous areas of economics and finance. To fully appreciate its intricacies, students should have a strong understanding of macroeconomics, international trade, and monetary theory. These foundational topics provide the context necessary to analyze how governments and central banks manage their currencies in relation to other nations' currencies.

A key aspect of exchange rate policy is its relationship to international trade. Students who are well-versed in trade theory and practice will be better equipped to understand how exchange rates influence exports, imports, and overall trade balances. This knowledge is crucial for comprehending the motivations behind various exchange rate policies and their potential consequences on a country's economic competitiveness.

Moreover, a solid grasp of monetary policy is indispensable when studying exchange rate policy. The two are closely intertwined, as decisions made by central banks regarding interest rates and money supply can have significant effects on a country's exchange rate. Familiarity with concepts such as inflation, interest rates, and monetary aggregates provides students with the tools to analyze how domestic monetary policies can influence and be influenced by exchange rate dynamics.

Financial markets also play a crucial role in exchange rate determination and policy implementation. Students with knowledge of how currency markets operate, including concepts like spot rates, forward rates, and currency derivatives, will have a distinct advantage in understanding the mechanisms through which exchange rate policies are executed and their impact on financial institutions and investors.

Additionally, an awareness of historical economic events and case studies can greatly enhance one's understanding of exchange rate policy. Examining past currency crises, successful policy interventions, and the evolution of international monetary systems provides valuable context for current policy debates and decisions.

While specific prerequisite topics may not be listed, students approaching the study of exchange rate policy should strive to build a strong foundation in these related areas of economics and finance. By doing so, they will be better prepared to analyze complex policy decisions, understand their rationale, and predict their potential outcomes in the global economic landscape.
