Comprehensive Study Guide on Multinational Finance and Exchange Rate Dynamics

Spot Market Liquidity and Exchange Rate Systems

• Spot Market Liquidity Definition: Market liquidity refers to the ease with which a currency can be bought or sold. A market is considered more liquid when there are more willing buyers and sellers.

• Highly Liquid Currencies: The spot markets for heavily traded currencies, specifically the Japanese yen ($JPY$), United States dollar ($USD$), and Euro ($EUR$), are categorized as very liquid.

• Impact on Multinational Corporations (MNCs): A currency's liquidity directly affects how easily an MNC can obtain or sell that currency. In an illiquid market, an MNC is typically unable to quickly purchase a currency at a reasonable exchange rate.

• Exchange Rate Systems:

  • Fixed Exchange Rate System: A system where the exchange rate is decided by the government or central bank.

  • Freely Floating System: A system where exchange rates are determined strictly by market supply and demand without central bank intervention.

  • Pegged Exchange Rate: A rate that is linked or fixed to the value of another currency.

Theories of International Business and Agency Costs

• Common Methods for International Business:

  • Exporting: Selling domestic goods in foreign markets.

  • Joint Ventures: Partnering with foreign entities to share risks and resources.

  • Licensing: Allowing foreign firms to use technology or intellectual property; this requires no capital investment for foreign operations but carries the risk of losing control over intellectual property.

  • Franchising: A strategy for international expansion where a foreign firm is allowed to operate under the MNC's brand name and specific guidelines.

• Theoretical Foundations:

  • Theory of Comparative Advantage: Assumes that countries benefit from specializing in the production of goods they can produce most efficiently.

  • Imperfect Markets Theory: Assumes that barriers to resource mobility across countries create opportunities for international business because resources do not move freely.

  • Product Cycle Theory: Suggests that MNCs relocate production and expand internationally as products mature and to exploit technological gaps.

• Agency Costs and Management:

  • Agency costs are generally higher for MNCs than domestic firms because monitoring foreign subsidiaries is more complex.

  • Centralized Management: The primary benefit is reduced agency costs through rigorous parent company oversight.

  • Management Incentives: Agency problems can be minimized by aligning management incentives with the overall goals of the MNC.

  • Decentralized Management: Increased autonomy for subsidiary managers can actually increase agency costs if not properly managed.

Fundamental Exchange Rate Theories

• Purchasing Power Parity (PPP):

  • Core Suggestion: Long-term exchange rates reflect differences in price levels between countries.

  • Relative PPP: Predicts that exchange rates adjust to fully reflect inflation rate differences. If inflation in Country A is higher than in Country B, Country A’s currency will depreciate against Country B’s currency.

  • Condition for PPP: PPP holds true when inflation differences are fully reflected in exchange rate changes.

• Fisher Effect: Suggests that nominal interest rates reflect expected inflation rates.

• International Fisher Effect (IFE): Suggests that currencies with higher interest rates are expected to experience currency depreciation.

• Interest Rate Parity (IRP):

  • Definition: The forward rate differs from the spot rate by an amount sufficient to offset the interest rate differential between two currencies.

  • IRP Formula: $\frac{F - S}{S} = \frac{1 + i_h}{1 + i_f} - 1$

  • Real-world Obstacles: Transaction costs and capital controls can prevent IRP from holding perfectly.

• Factors influencing appreciation: High interest rates are a factor that most directly affects currency appreciation.

Arbitrage Mechanisms and Market Efficiency

• Locational Arbitrage:

  • Occurs when there is a discrepancy in exchange rates between different banks for the same currency.

  • Profit Calculation Example: If Bank A quotes a bid rate of $\$0.300$ and an ask rate of $\$0.305$ for Malaysian ringgit ($MYR$), and Bank B quotes a bid rate of $\$0.306$ and an ask rate of $\$0.310$.

    1. Use $\$500,000$ to buy $MYR$ at Bank A's ask: $\frac{500,000}{0.305} = 1,639,344.262\,MYR$.

    2. Convert $MYR$ back to $USD$ at Bank B's bid: $1,639,344.262 \times 0.306 = \$501,639.3443$.

    3. Profit: $\$501,639.3443 - \$500,000 = \$1,639$.

  • Market Adjustment: As locational arbitrage occurs, the ask rate for the currency at the cheaper bank (Bank A) will increase, and the bid rate at the more expensive bank (Bank B) will decrease.

• Triangular Arbitrage: Occurs when discrepancies exist in cross-exchange rates among three different currencies.

• Covered Interest Arbitrage: Occurs when interest rate parity does not hold, allowing profits from the difference between the interest rate differential and the forward premium/discount.

• Carry Trade: A strategy involving borrowing in low-yield (low-interest) currencies to invest in high-yield (high-interest) currencies.

Currency Derivatives and Hedging

• Purpose of Derivatives: To provide tools for multinational corporations to hedge against adverse currency movements.

• Forward Contracts:

  • Forward Premium/Discount: Indicates the percentage by which the forward rate is above or below the spot rate.

  • Calculation: If the 90-day forward rate is $\$1.083$ and the spot rate is $\$1.064$, the forward premium is calculated as: $\frac{1.083 - 1.064}{1.064} \times \frac{360}{90} = 7.143\%$

  • Limitation: They lock a firm into a fixed exchange rate, which may prevent them from benefiting from favorable market fluctuations.

• Options:

  • Call Options: Purchased by firms that expect a currency to appreciate substantially.

  • Put Options: An option with a strike price of $\$0.012$ when the current exchange rate is $\$0.011$ is considered "in the money."

• Currency Swaps: Allow firms to exchange debt obligations denominated in different currencies.

International Trade and the J-Curve Effect

• Current Account Balances:

  • If home inflation increases relative to other countries, the current account balance decreases.

  • If government restrictions on imports increase, the current account balance increases.

• J-Curve Effect:

  • Definition: Describes the short-run tendency for a country's trade balance to deteriorate and the long-run tendency to improve following a currency depreciation.

  • Reason for Initial Worsening: Prices of imports rise immediately while quantities of exports and imports take time to adjust. Prearranged trade contracts also delay adjustments.

  • Recovery Phase: Signifies the stabilization of the trade balance after quantities of exports and imports adjust in the long term.

  • Necessary Condition: Effective improvement requires elastic demand for exports and imports in the long run.

• Barriers to Correcting Trade Deficits: A weak currency may not fix a deficit if local companies increase prices to stay competitive or if international trade transactions were prearranged.

Quantitative Determinations and Numerical Examples

• Cross Exchange Rate Calculation: If a Canadian dollar ($CAD$) is worth $\$0.81$ and a Singapore dollar ($SGD$) is worth $\$0.74$, the cross exchange rate $CAD/SGD$ is calculated as: $\frac{0.81}{0.74} = 1.0946$.

• Interest Rate Parity Calculation: If the spot rate $S(USD/JPY) = 84$, the forward rate $F(USD/JPY) = 92$, and the domestic $USD$ interest rate is $5\%$. The interest rate for the Japanese Yen can be derived using the IRP formula $\frac{F-S}{S} = \frac{1 + i_h}{1 + i_f} - 1$, resulting in approximately $9.52\%$.

• Hedging Receipts: A company expecting to receive $5,000,000\,JPY$ in 60 days hedges by selling yen forward at a rate of $\$0.0093$. The total dollars received will be: $5,000,000 \times 0.0093 = \$46,500$.

• PPP and Interest Rates: If investors require a real rate of $5\%$, the nominal $U.S.$ rate is $10\%$, and the nominal Canadian rate is $8\%$, under PPP, the Canadian dollar will appreciate by approximately $2\%$.
