Capital Flows and the FX Market

Economics

The Foreign Exchange Market and Exchange Rates

Learning Outcome Statement:

describe the foreign exchange market, including its functions and participants, distinguish between nominal and real exchange rates, and calculate and interpret the percentage change in a currency relative to another currency

Summary:

The Foreign Exchange Market and Exchange Rates module provides an in-depth understanding of the FX market, its size, operations, and the roles of various participants. It explains the concepts of nominal and real exchange rates, and how to calculate and interpret changes in currency values. The module also covers the impact of exchange rates on international trade and capital flows, and the various exchange rate regimes.

Key Concepts:

Foreign Exchange Market

The FX market is the world's largest financial market where currencies are traded against each other. It operates 24 hours a day and involves a wide range of participants from large investment funds to individual traders.

Nominal and Real Exchange Rates

Nominal exchange rates are the actual rates quoted in the market, while real exchange rates are adjusted for price levels in each country to reflect the relative purchasing power between countries.

Percentage Change in Currency Value

Calculating the percentage change in a currency relative to another helps in understanding the appreciation or depreciation of currencies, which is crucial for making informed trading decisions.

Exchange Rate Regimes

Exchange rate regimes can be floating, fixed, or a hybrid. These regimes determine how a country manages its currency in relation to other currencies, influenced by political and economic factors.

Impact on Trade and Capital Flows

Exchange rates influence a country's trade balance and capital flows. Changes in exchange rates can affect the competitiveness of a country's goods and services internationally.

Formulas:

Percentage Change in Exchange Rate

\text{Percentage Change} = \left(\frac{\text{New Rate} - \text{Old Rate}}{\text{Old Rate}}\right) \times 100\%

This formula calculates the percentage change in an exchange rate, indicating how much a currency has appreciated or depreciated relative to another.

Variables:

$New Rate$ :: The new exchange rate
$Old Rate$ :: The previous exchange rate

Units: percent (%)

Real Exchange Rate

R_{d/f} = S_{d/f} \times \left(\frac{P_f}{P_d}\right)

This formula defines the real exchange rate, which adjusts the nominal rate by the price levels in each country, reflecting the true purchasing power of the currencies.

Variables:

$R_{d/f}$ :: Real exchange rate between domestic (d) and foreign (f) currency
$S_{d/f}$ :: Nominal spot exchange rate (domestic currency per unit of foreign currency)
$P_f$ :: Foreign price level
$P_d$ :: Domestic price level

Units: dimensionless

Exchange Rate Regimes: Ideals and Historical Perspective

Learning Outcome Statement:

describe exchange rate regimes and explain the effects of exchange rates on countries’ international trade and capital flows

Summary:

This LOS explores the various exchange rate regimes and their historical evolution, detailing how they influence international trade and capital flows. It discusses the ideal currency regime, the historical perspective on currency regimes, and provides a taxonomy of current currency regimes. The content also explains the relationship between exchange rates and trade balances, highlighting how different regimes impact economic stability, investment decisions, and monetary policy independence.

Key Concepts:

Ideal Currency Regime

An ideal currency regime would feature a fixed exchange rate, full convertibility of currencies, and the ability for countries to conduct independent monetary policies. However, these conditions are inherently contradictory, making such an ideal regime unfeasible.

Historical Perspective on Currency Regimes

Historically, currency regimes have evolved from the gold standard to the Bretton Woods system, and eventually to more flexible exchange rate systems. Each system had its own mechanisms and impacts on global trade and monetary policy.

Taxonomy of Currency Regimes

Currency regimes can range from fixed systems to fully floating systems, with hybrids in between such as currency boards, crawling pegs, and managed floats. Each type has distinct characteristics and implications for monetary policy and economic stability.

Exchange Rates and Trade Balance

Exchange rates directly affect a country's trade balance, where a trade deficit must be matched by a capital account surplus, and vice versa. The regime type influences how exchange rates adjust to balance these accounts.

Formulas:

Trade Balance Identity

X - M = (S - I) + (T - G)

This formula links a country's trade balance to its fiscal policy and investment-savings balance, illustrating how a trade surplus or deficit aligns with broader economic parameters.

Variables:

$X$ :: Exports
$M$ :: Imports
$S$ :: Private savings
$I$ :: Investment in plant and equipment
$T$ :: Taxes net of transfers
$G$ :: Government expenditure

Units: Monetary units (e.g., dollars)

Capital Restrictions

Learning Outcome Statement:

describe common objectives of capital restrictions imposed by governments

Summary:

Capital restrictions are measures imposed by governments to control the flow of capital into and out of a country. These restrictions can be motivated by various objectives such as protecting domestic industries, managing the balance of payments, and achieving macroeconomic stability. They can take the form of taxes, controls on transactions, or outright prohibitions.

Key Concepts:

Reasons for Capital Restrictions

Governments impose capital restrictions to achieve specific economic, strategic, or defensive objectives. These may include managing employment levels, regional development, or protecting strategic industries like defense and telecommunications from excessive foreign ownership.

Types of Capital Restrictions

Capital restrictions can be classified into controls on inward and outward flows. Inward controls may limit the amount and sectors in which foreign capital can be invested. Outward controls may include restrictions on the repatriation of capital, profits, and other financial returns.

Effects of Capital Restrictions

While capital restrictions can stabilize economies during crises by controlling capital flight and managing exchange rates, they can also lead to negative market perceptions, making it difficult and costly for the country to access foreign funds in the long term.

Historical Context and Modern Usage

Originally developed during World War I to finance war efforts and prevent capital outflows, modern capital controls are often used in developing nations to manage economic crises and prevent capital flight, as seen in Malaysia's use of capital controls during the 1998-2001 financial crisis.
