Review Questions

• How do arbitrageurs contribute to market efficiency in the context of currency derivatives?
  • Arbitrageurs help maintain market efficiency by swiftly capitalizing on price discrepancies between different markets. When they identify an opportunity, such as a mispriced currency derivative, they execute trades that bring prices back into alignment. This process reduces the likelihood of significant deviations from fair value, ensuring that information is quickly reflected in asset prices, which ultimately benefits all market participants.
• Discuss the relationship between interest rates and the actions of arbitrageurs in foreign exchange markets.
  • Interest rate differentials between countries can create arbitrage opportunities for traders. When one country offers higher interest rates than another, it can lead to mispricing in currency derivatives as traders seek to profit from these differences. Arbitrageurs take advantage of these situations by borrowing in low-interest-rate currencies and investing in high-interest-rate ones, which helps correct pricing inefficiencies and aligns the returns expected from these assets with their underlying risks.
• Evaluate the impact of technological advancements on the strategies employed by arbitrageurs and overall market dynamics.
  • Technological advancements have significantly transformed the strategies of arbitrageurs by enabling them to identify and execute trades more rapidly than ever before. High-frequency trading algorithms can analyze vast amounts of data within milliseconds to spot arbitrage opportunities across various markets. This rapid response helps improve overall market dynamics by quickly correcting mispricings, but it can also lead to increased volatility, as large volumes of trades executed at once may amplify price movements.
