What Is a Carry Trade?
A carry trade is a financial strategy where an investor borrows money in a currency with a low interest rate and then invests that money into a different currency or asset that offers a higher return. The goal is to capitalize on the difference between the borrowing and investment rates.
While primarily associated with the forex and currency trading sectors, this strategy can also be applied to other financial instruments such as stocks, bonds, and commodities.
How Carry Trades Operate
The typical process of a carry trade involves borrowing funds in a currency that has a very low or even near-zero interest rate—take the Japanese yen (JPY) as an example, which has had low rates for an extended period. The borrowed funds are then converted into a currency that has a higher interest rate, such as the US dollar. The next step is to invest in assets like US government bonds or other financial instruments that offer attractive returns.
For instance, if you borrow yen at an interest rate of 0% and invest in an asset yielding 5.5%, your net earnings would be that 5.5%, minus any associated fees or costs. Essentially, it’s a method of turning low-cost borrowed funds into a profitable investment, assuming exchange rates remain favorable.
Why Investors Favor Carry Trades
Carry trades are popular among investors because they offer a way to generate consistent returns from the interest rate differential, independent of the asset's value appreciating. This strategy is particularly favored by large entities like hedge funds and institutional investors, who possess the expertise and resources to effectively manage the inherent risks.
Often, carry trades are conducted with leverage, meaning investors borrow significantly more than they actually hold in capital. This can amplify potential returns but also heightens the risk of substantial losses if the trade doesn’t go as planned.
Examples of Carry Trades
One of the most recognized carry trade examples is the yen-dollar strategy. For many years, investors borrowed Japanese yen and invested those funds in US assets that provided significantly higher returns. This strategy worked well as long as the interest rate differential remained advantageous and the yen didn’t experience a sudden appreciation against the dollar, which notably occurred in July 2024 (more on this later).
Another common carry trade involves emerging markets. In this scenario, investors borrow in a low-interest-rate currency and invest in higher-yielding currencies or bonds from emerging markets. While the potential for returns is substantial, these trades are highly sensitive to global market conditions and shifts in investor sentiment. If market conditions deteriorate, what was once a profitable trade can quickly become a significant loss.
Risks Associated with Carry Trades
As with any investment approach, carry trades come with risks. The most prominent risk is currency fluctuation. If the currency in which you’ve borrowed appreciates against the currency you’ve invested in, your profits can diminish or even turn into losses when you convert back.
For example, if you borrow in yen and invest in dollars, a strengthening of the yen against the dollar could result in losses when converting back to yen. Interest rate changes also pose a risk. Should the central bank of the borrowed currency raise interest rates, your borrowing costs will increase, cutting into your profits. Conversely, if the central bank of the invested currency reduces rates, your returns will decrease.
These risks became painfully clear during the 2008 financial crisis, where many investors suffered substantial losses on carry trades, especially those involving the yen. In 2024, shifts in Japan’s monetary policy caused the yen to appreciate, triggering a wave of unwinding carry trades and subsequent market volatility.
The Role of Market Conditions
Carry trades tend to perform well in stable, optimistic market environments. When markets are calm and bullish, currency values and interest rates generally remain steady, encouraging investors to take on more risk.
However, during periods of market instability or economic uncertainty, carry trades can become extremely risky. In volatile, highly leveraged markets, investors might rush to unwind their carry trades, leading to sharp currency fluctuations and potentially causing broader financial instability.
A prime example occurred in July 2024, when the Bank of Japan unexpectedly raised interest rates, causing the yen to surge in value. This led many investors to hastily unwind their yen carry trades, resulting in a sell-off of higher-risk assets to repay yen loans. This not only shook currency markets but also triggered a global sell-off in riskier investments, with the situation exacerbated by leveraged positions.
Final Thoughts
Carry trades offer a compelling opportunity to profit from differences in interest rates between currencies or assets. However, the strategy is not without its risks, particularly in leveraged and volatile markets.
Success in carry trades requires a deep understanding of global markets, currency movements, and interest rate trends. Given the potential for unexpected market shifts, carry trades are better suited for experienced investors or institutions equipped to manage the associated risks effectively.
