Review Questions

• How does arbitrage contribute to market efficiency within foreign exchange markets?
  • Arbitrage contributes to market efficiency by quickly correcting price discrepancies between different markets. When traders engage in arbitrage, they buy a currency at a lower price in one market and sell it at a higher price in another. This action reduces the price difference between the two markets as more traders respond, leading to more accurate pricing and minimizing potential risks for investors.
• Discuss the risks involved in executing an arbitrage strategy in foreign exchange markets.
  • While arbitrage is often seen as low-risk, there are still several risks involved. Transaction costs can eat into profits if they are high enough to negate the benefits of price differences. Additionally, rapid market changes can lead to slippage where the expected price may not be achieved due to delays in executing trades. There’s also the risk of execution failure, especially in highly volatile markets, which can prevent traders from completing their intended transactions.
• Evaluate how advancements in technology have changed the landscape of arbitrage opportunities in currency trading.
  • Advancements in technology have significantly transformed the landscape of arbitrage opportunities in currency trading by enabling faster execution and real-time analysis. High-frequency trading algorithms can analyze multiple exchanges simultaneously and execute trades within milliseconds, making it easier for traders to capitalize on fleeting price discrepancies. As a result, traditional arbitrage strategies are now often automated, creating an increasingly competitive environment where only those with cutting-edge technology can effectively engage in arbitrage.
