🏪International Financial Markets Unit 5 – Currency Derivatives & Hedging Strategies

Basics of Currency Derivatives

• Currency derivatives financial instruments derive their value from underlying currency exchange rates
• Enable market participants to manage currency risk, speculate on currency movements, or take advantage of interest rate differentials between countries
• Common types include currency forwards, futures, options, and swaps (covered in more detail in the next section)
• Traded over-the-counter (OTC) or on organized exchanges (such as the Chicago Mercantile Exchange)
  • OTC markets offer more flexibility in terms of contract size, expiration date, and customization
  • Exchange-traded derivatives standardized contracts, centralized clearing, and higher liquidity
• Notional value of the contract represents the amount of currency being bought or sold
• Settlement can be physical delivery of the underlying currencies or cash settlement based on the difference between the agreed-upon exchange rate and the prevailing market rate at expiration

Types of Currency Derivatives

• Currency forwards binding agreements between two parties to buy or sell a specific amount of currency at a predetermined exchange rate on a future date
  • Customizable in terms of amount, exchange rate, and settlement date
  • Often used by corporations to hedge foreign currency exposures arising from international trade or investments
• Currency futures standardized contracts to buy or sell a specific amount of currency at a predetermined exchange rate on a future date
  • Traded on organized exchanges with fixed contract sizes and expiration dates
  • Require initial margin and daily mark-to-market settlements
• Currency options give the holder the right, but not the obligation, to buy (call option) or sell (put option) a specific amount of currency at a predetermined exchange rate (strike price) on or before a future date (expiration date)
  • Buyer of the option pays a premium to the seller for this right
  • Provides flexibility and limited downside risk for the buyer, while the seller assumes unlimited potential losses
• Currency swaps agreements between two parties to exchange principal and interest payments in different currencies over a specified period
  • Often used to hedge long-term currency exposures or to exploit interest rate differentials between countries
  • Can be fixed-for-fixed, fixed-for-floating, or floating-for-floating interest rate swaps

Market Participants and Their Roles

• Commercial banks act as market makers, providing liquidity by quoting bid and ask prices for currency derivatives
  • Also offer derivative products to their corporate and institutional clients for hedging or investment purposes
• Corporations use currency derivatives to hedge their foreign currency exposures arising from international trade, investments, or financing activities
  • Aim to minimize the impact of adverse currency movements on their financial statements and cash flows
• Institutional investors (pension funds, mutual funds, insurance companies) use currency derivatives for hedging, speculation, or diversification purposes
  • May have specific currency exposure targets or limits based on their investment mandates or risk management policies
• Central banks participate in currency derivative markets to implement monetary policy, manage foreign exchange reserves, or intervene in foreign exchange markets
  • Actions can have significant impact on currency market sentiment and volatility
• Hedge funds and proprietary trading firms use currency derivatives for speculative purposes, aiming to profit from expected currency movements or market inefficiencies
  • Often employ sophisticated trading strategies and leverage to amplify returns

Pricing and Valuation Methods

• Currency forward and futures prices based on the interest rate parity theory, which states that the forward exchange rate should be equal to the spot exchange rate adjusted for the interest rate differential between the two currencies
  • Forward price = Spot price × $\frac{(1 + r_d)^t}{(1 + r_f)^t}$, where $r_d$ and $r_f$ are the domestic and foreign interest rates, and $t$ is the time to maturity
• Option pricing models (Black-Scholes, Garman-Kohlhagen) used to determine the theoretical value of currency options based on underlying factors such as the spot exchange rate, strike price, time to expiration, interest rates, and implied volatility
  • Implied volatility represents the market's expectation of future currency volatility and is a key input in option pricing models
• Monte Carlo simulation technique used to value complex currency derivatives or portfolios by simulating a large number of possible future price paths based on assumed probability distributions and correlations
• Value-at-risk (VaR) models used to estimate the potential loss of a currency derivative portfolio over a given time horizon and confidence level
  • Historical simulation, variance-covariance, and Monte Carlo simulation are common VaR methodologies

Risk Factors in Currency Markets

• Exchange rate risk arises from potential adverse movements in currency exchange rates, which can impact the value of currency derivatives and the underlying exposures they are meant to hedge
  • Influenced by macroeconomic factors (interest rates, inflation, GDP growth), political events, and market sentiment
• Interest rate risk refers to the sensitivity of currency derivatives to changes in domestic and foreign interest rates
  • Changes in interest rate differentials can affect the pricing and valuation of currency forwards, futures, and swaps
• Liquidity risk arises when there is insufficient market depth or participation, making it difficult to execute large transactions without significant price impact
  • Can be exacerbated during times of market stress or uncertainty
• Counterparty credit risk refers to the potential default or non-performance of the other party in a currency derivative contract
  • Particularly relevant for OTC derivatives, where there is no central clearing or collateralization
• Operational risk includes potential losses from inadequate or failed internal processes, systems, human errors, or external events
  • Importance of robust risk management frameworks, trade confirmation and reconciliation processes, and compliance with regulations

Hedging Strategies and Techniques

• Forward hedging involves locking in a future exchange rate using currency forwards or futures to eliminate exchange rate risk on a known future foreign currency exposure
  • Appropriate when the timing and amount of the exposure are certain
• Option hedging uses currency options to provide protection against adverse exchange rate movements while retaining the ability to benefit from favorable movements
  • Suitable when there is uncertainty about the timing or amount of the exposure, or when the hedger wants to maintain some upside potential
• Cross-hedging involves hedging an exposure in one currency using derivatives in a different but correlated currency
  • Useful when there are no direct hedging instruments available or when the liquidity in the direct currency pair is limited
• Hedge ratios determine the optimal amount of currency derivatives to use in relation to the underlying exposure being hedged
  • Minimum-variance hedge ratio aims to minimize the variance of the hedged portfolio by considering the correlation and volatility of the exposure and the hedging instrument
• Dynamic hedging involves continuously adjusting the hedge position in response to changes in market conditions or the underlying exposure
  • Requires active monitoring and management of the hedge portfolio
• Natural hedging involves offsetting foreign currency exposures within a company's operations, such as matching foreign currency revenues with expenses or assets with liabilities
  • Can reduce the need for external hedging using currency derivatives

Regulatory Framework and Compliance

• International Swaps and Derivatives Association (ISDA) provides standardized documentation (ISDA Master Agreement) and protocols for OTC currency derivatives
  • Aims to reduce legal and operational risks by establishing clear terms and conditions for derivative transactions
• Dodd-Frank Wall Street Reform and Consumer Protection Act (U.S.) introduced mandatory clearing, trade reporting, and margin requirements for certain OTC currency derivatives
  • Aims to increase transparency and reduce systemic risk in the derivatives market
• European Market Infrastructure Regulation (EMIR) imposes similar requirements for OTC derivatives in the European Union
  • Includes mandatory clearing for eligible contracts, trade reporting to trade repositories, and risk mitigation techniques for uncleared derivatives
• Basel III capital and liquidity standards require banks to hold additional capital against their currency derivative exposures and to manage liquidity risk arising from potential margin calls
• Know Your Customer (KYC) and Anti-Money Laundering (AML) regulations require financial institutions to verify the identity of their counterparties and to monitor for suspicious activities in currency derivative transactions
• Compliance with these regulations requires robust internal controls, risk management systems, and reporting processes
  • Non-compliance can result in significant fines, legal liabilities, and reputational damage

Real-World Applications and Case Studies

• Multinational corporations use currency derivatives to hedge their foreign exchange risk arising from cross-border trade, investments, and financing activities
  • Example: A U.S. company with EUR-denominated sales can use EUR/USD forward contracts to lock in a favorable exchange rate and protect its profit margins
• Institutional investors use currency derivatives to manage the currency exposure of their international investment portfolios
  • Example: A U.S. pension fund with investments in Japanese equities can use JPY/USD futures to hedge the currency risk and preserve the value of its assets
• Central banks use currency derivatives to intervene in foreign exchange markets and manage their foreign exchange reserves
  • Example: The Bank of Japan can use USD/JPY options to stabilize the value of the Japanese yen during periods of market turbulence
• Hedge funds and proprietary trading firms use currency derivatives to speculate on expected currency movements and to exploit market inefficiencies
  • Example: A hedge fund can use a combination of currency forwards, options, and swaps to implement a carry trade strategy, borrowing in low-yielding currencies and investing in high-yielding currencies
• Case study: The Swiss National Bank's (SNB) decision to remove the EUR/CHF exchange rate floor in January 2015 led to significant losses for many currency derivative market participants
  • The sudden appreciation of the Swiss franc resulted in large margin calls and liquidity pressures, highlighting the importance of robust risk management and stress testing practices
