Carry Trade in algo trading
The world of quantitative trading is full of elaborate and complex strategies, and among them, the "Carry Trade" strategy occupies a prominent place. In the context of algo trading optimization, it's crucial to understand the nuances of this strategy to get the most out of it.
What is Carry Trade?
The Carry Trade strategy traditionally aims to capitalize on the interest rate differential between high and low interest rate economies. For example, an investor might borrow in a low-interest country like Japan at 1% and invest in a high-interest country like the USA at 3%. The return is then equal to the difference in rates, i.e. 2%. However, due to exchange rate fluctuations, this strategy presents significant risks.

Origin of the term "Carry"
The term "carry" comes from the world of commodities, where an investor earns a positive or negative return by holding an asset. For example, holding gold generates a negative "carry" due to storage costs. But in most cases, "carry" is often associated with currency trading.
Carry Trade and Unhedged Interest Rate Parity (UIRP)
The main idea behind the currency carry trade strategy is the failure of UIRP. According to UIRP, the difference between spot interest rates should equal the difference between future exchange rates. However, in reality, this relationship doesn't always work, offering an exploitative opportunity for traders.
Several studies, such as those by Cumby and Obsfeld (1981), have highlighted this divergence. Later, risk-based explanations, such as the currency risk premium, were proposed to explain this anomaly.
Research such as that by Bacchetta and Wincoop (2007) showed that the failure of UIRP was due to the fact that a small proportion of foreign currencies were actively managed. Lustig and Verdelhan (2007), meanwhile, introduced a new carry trade strategy that demonstrated significant excess returns.
Carry Trade risks
While seemingly a profitable strategy, the carry trade is not without risk. Investors need to be aware of rare but important events, such as the unwinding of a carry trade, which can lead to significant losses.
Algo Trading and Carry Trade
Algo trading, with its ability to process large quantities of data and execute orders in real time, can optimize the implementation of the carry trade strategy. Using advanced algorithms, traders can better anticipate exchange rate movements and adjust their positions accordingly.
Events such as the Icelandic financial crisis of 2008-2011 and the rapid appreciation of the yen in 2008 demonstrate the impact of the carry trade on global markets. These events underline the importance of prudent risk management when using this strategy.
The carry trade strategy, while lucrative, requires in-depth understanding and careful risk management. In the world of algo trading, with the right tools and a well-defined strategy, traders can maximize returns while minimizing potential risks.
