What Is Uncovered Interest Arbitrage?
Let me explain uncovered interest arbitrage to you directly: it's a type of arbitrage where you switch from your domestic currency, which has a lower interest rate, to a foreign currency that offers higher interest on deposits. Remember, there's a foreign exchange risk involved because you'll eventually need to convert those foreign proceeds back to your domestic currency. I want you to understand that the 'uncovered' part means this risk isn't protected by any forward or futures contract.
Key Takeaways
To keep it straightforward, uncovered interest arbitrage means switching from a low-interest domestic currency to a high-interest foreign one for deposits. The 'uncovered' term highlights that the foreign exchange risk goes unhedged without forward or futures contracts. Essentially, it's an unhedged currency swap to chase higher returns from interest rate differences.
How Uncovered Interest Arbitrage Works
Here's how it operates: you engage in an unhedged exchange of currencies to capitalize on the interest rate gap between them for better returns. Your total returns hinge heavily on currency fluctuations, as negative movements can erase gains or even result in losses. For instance, if the foreign investment yields a 3% interest differential and the foreign currency appreciates by 2% against your domestic one during the period, you're looking at a 5% total return. But if it depreciates by 4%, that turns into a -1% return. I advise you to consider these dynamics carefully in any such strategy.
