Notes on Exchange Rates and Foreign Exchange Market from ECON 335

Introduction to Exchange Rates and Foreign Exchange Market

  • Impact of Exchange Rates:

    • Exchange rates heavily influence the prices of goods across different currencies, significantly affecting international trade.

    • Affect trading in assets like stocks and bonds.

    • The foreign exchange market sees trillions in trade daily, with substantial economic implications.

Exchange Rate Basics

  • Definition:

    • An exchange rate (E) is the price of foreign currency in terms of domestic currency.

  • Quotations:

    • Can be expressed in two ways:

    • Home currency units per one unit of foreign currency.

    • Foreign currency units per one unit of home currency.

  • Example:

    • U.S. dollars per yen (E$/¥) and Danish krone per euro (Ekr/€).

Exchange Rates Over Time

  • Table 10-1 (Exchange Rate Quotations):

    • Exchange rates for major currencies on November 15, 2019, compared to November 15, 2018.

    • This table captures rates against the dollar and euro, illustrating changes in valuation over the year.

Appreciations and Depreciations

  • Terminology:

    • Appreciation: Currency buys more of another; increases in value.

    • Depreciation: Currency buys less of another; decreases in value.

  • Example Calculations:

    • If E$/€ rises, more dollars are needed for one euro, implying dollar depreciation. Conversely, if it falls, it implies dollar appreciation.

    • Example shown: From $1.1325 in 2018 to $1.1045 in 2019, leading to a depreciation of 2.47% for euro against the dollar.

Multilateral Exchange Rates

  • Calculating Effective Exchange Rates:

    • Combine bilateral exchange rates weighted by trade volume.

    • Example:

    • If a currency appreciates by 10% with 40% trade with country 1 and depreciates by 30% with 60% trade with country 2:

      • Effective exchange rate change = (10% * 0.4) + (-30% * 0.6) = -14%.

Fixed vs. Floating Exchange Rate Regimes

  • Fixed Rate:

    • Fluctuates within a narrow range, requiring government intervention.

  • Floating Rate:

    • Fluctuates more freely, subject to market forces. Examples in the U.S., Canada, and Eurozone—with the Danish krone exhibiting fixed characteristics.

The Forex Market

  • Market Overview:

    • Not organized, trades “over the counter.”

    • April 2019 recorded daily forex trading at $6.6 trillion.

  • Market Operations:

    • Spot contracts are the most common transactions, often accounting for over 80% of forex trades.

  • Transaction Costs:

    • Spreads (difference between buy and sell prices) range widely and contribute to market frictions.

Foreign Exchange Derivatives

  • Contracts Overview:

    • Includes forwards, swaps, futures, and options—used for hedging and speculation.

  • Examples:

    • Hedging: Locking in future exchange rates to avoid potential losses.

    • Speculation: Taking positions based on anticipated currency rate movements.

Government Regulation and Capital Controls

  • Regulatory Actions:

    • Government may impose restrictions on forex trading or capital movements.

Arbitrage and Exchange Rates

  • Arbitrage Mechanisms:

    • Ensures that currency trades maintain consistent prices across exchanges, avoiding profit opportunities from discrepancies.

  • Cross Rates:

    • Use of two currencies to derive exchange rates across a third currency (vehicle currency).

Interest Parity Conditions

  • Covered Interest Parity (CIP):

    • Ensures that returns from investing in different currencies equalize when exchange rate risk is managed through forward contracts.

  • Uncovered Interest Parity (UIP):

    • No-arbitrage condition under exchange rate risk, relying on future spot rate expectations.

    • The expected rate of depreciation should align with interest rates across currencies.

Evidence of Interest Parity

  • Expected changes in spot and forward rates should converge under UIP and CIP, indicating market equilibrium.

  • Indicators show that differences in interest rates correlate with expected currency valuations, affirming UIP holds approximately.

Summary of Concepts

  • Effective exchange rates reflect aggregate currency strength against a basket, influenced by market volatility and trading behavior.

  • The forex market operates as a complex system where government policies, trading strategies, and arbitrage opportunities interact continuously to influence currency valuations over time.

Exchange Rates for Ecuador and Denmark

Ecuador and Denmark provide two contrastive examples of exchange rate dynamics and trade implications. Below is a detailed exploration of how exchange rates affect these two countries' economies in relation to foreign exchange markets.

Historical Exchange Rate Overview

  • Ecuador:

    • Ecuador uses the U.S. dollar as its official currency since the dollarization in 2000.

    • This peg to the U.S. dollar stabilizes prices and minimizes exchange rate risk, essential for a country reliant on exports like oil and bananas.

  • Denmark:

    • Denmark employs the Danish krone, which is pegged to the euro under the European Exchange Rate Mechanism (ERM II).

    • This system helps maintain stability in trade relations with the eurozone.

Impact on International Trade

  • Ecuador:

    • As a dollarized economy, Ecuador benefits from lower transaction costs in trade with the U.S. and countries using the dollar.

    • However, without monetary policy flexibility, it cannot adjust interest rates for economic stabilization.

    • Changes in U.S. dollar value can influence Ecuador's export competitiveness, impacting its balance of trade.

  • Denmark:

    • The krone's value against the euro affects Danish exports significantly since the EU is a major trading partner.

    • Denmark's ability to maintain a stable exchange rate supports its export-oriented economy that spans pharmaceuticals, shipping, and agriculture.

    • Changes in the euro’s strength sway trade balances, especially when dealing with non-EU countries.

Currency Strength and Economic Performance

  • Ecuador:

    • Currency appreciation leads to more expensive exports, potentially hurting the economy.

    • A depreciating U.S. dollar can enhance its competitiveness but also increases the cost of imports.

  • Denmark:

    • The krone's stability improves investor confidence, fostering foreign direct investment (FDI).

    • A stronger krone can erode competitiveness in the export market but positively impacts imports, making foreign goods cheaper.

Market Characteristics and Regulation

  • Ecuador:

    • Limited government intervention since it doesn’t control monetary policy.

    • Economic shocks that affect the U.S. dollar also directly impact Ecuador's financial health.

  • Denmark:

    • The Danish government has actively managed its currency through policy measures, often adjusting interest rates to maintain the krone’s peg to the euro.

    • This regulatory approach allows for more maneuverability during economic fluctuations.

Conclusion

Understanding the exchange rate mechanisms of Ecuador and Denmark illustrates the varied impacts on their trade and economic stability. While Ecuador’s dollarization provides some benefits in transaction cost and price stability, it also comes with limitations in monetary policy. Denmark's pegged exchange provides stability, which is crucial for its export-focused economy but must be balanced against maintaining competitive pricing in global markets.
