How the Yen carry trade led to a global market rout?

As a seasoned investor with years of experience navigating the volatile world of finance, I’ve seen my fair share of market turmoil—and the recent yen carry trade debacle is no exception. The swift and dramatic consequences of this seemingly simple strategy serve as a stark reminder that every investment carries an inherent risk, and it’s essential to weigh these risks against potential rewards before diving in.

On August 5, as markets plunged, a common question arose: What exactly is carry trade? Unveil the workings of this lesser-known financial tactic that subtly intensified the turmoil, causing significant losses across the globe.

2023-08-05 is likely to be remembered as one of the stormiest days in modern financial times. That day, the markets trembled, and investors clung to their seats as over 10 billion dollars vanished in just a few short hours.

Labeled as ‘Crypto Black Monday’, the cryptocurrency market experienced a significant drop in value, causing the total market capitalization to plummet from an impressive $2.16 trillion on August 4th, down to an astounding $1.78 trillion on August 5th – marking a steep decline of almost 18%.

However, the ripples didn’t just affect the cryptocurrency market. Significant drops were seen in major global stock markets as well, such as the NASDAQ100 in the U.S., the FTSE100 in the UK, and India’s NIFTY50, causing investors to feel shaky and disoriented.

As an analyst, I experienced a significant drop in the Japanese market yesterday, particularly with the Nikkei225 index plunging approximately 12.5% in a single trading session. This marked the sharpest decline since 1987. The entire market was affected, as evidenced by the sea of red across all the boards.

Among several factors causing market turbulence, one significant contributor was the unraveling of the yen carry trade. This includes concerns about a potential U.S. economic downturn and escalating geopolitical conflicts in the Middle East.

As an analyst, I find it essential to grasp the chain reaction, or ‘domino effect’, that set off the worldwide financial quake we experienced.

To put it simply, a carry trade is an investment strategy where an investor borrows money in a low-interest currency to invest in a higher-yielding one with the aim of profiting from the interest rate differential. Now, let’s examine this technique, dissect its components, and understand how it significantly influenced market volatility.

What is carry trade?

The term “carry trade” might sound fancy, but it’s actually a pretty simple concept once you break it down. 

Consider obtaining funds from a nation with exceptionally low-interest rates, then utilizing those funds to invest in a different country offering significantly higher interest rates. The aim is to collect the gap between the minimal expense of lending and the elevated profits generated.

As a seasoned investor with a background in global finance, I have always been intrigued by the concept of the “carry trade.” Having lived and worked in both Japan and the United States, I have witnessed firsthand the stark difference in interest rates between these two economies.

As someone who has spent years studying and observing financial markets, I can attest to the fact that the carry trade is no mere curiosity or niche trading strategy. It’s a colossal global phenomenon that moves trillions of dollars across borders every day. The sheer scale of this practice is mind-boggling, and it’s one of the reasons why certain currencies like the yen see such high trading volume on a daily basis. I have witnessed firsthand the impact of carry trades on currency markets, and I can assure you that they are a powerful force in shaping exchange rates around the world.

Engaging in carry trades significantly influences worldwide financial systems. When these strategies are widely adopted, they tend to boost the worth of currencies providing elevated yields.

However, when investors decide to liquidate their carry trade positions (which involves selling them), it might cause significant fluctuations in the market, a phenomenon recently observed with the yen.

Let’s understand it with some examples.

Examples of a carry trade

• Borrowing yen at 0.1% interest, an investor converts it to Australian dollars to buy bonds offering a 5% yield, aiming to profit from the difference in interest rates.

• Taking out a Swiss franc loan at 0.5%, the investor converts it to Turkish lira and invests in Turkish real estate, benefiting from higher returns but risking currency fluctuations.

• An investor borrows euros at a low rate and invests in Brazilian agriculture stocks, looking to capitalize on Brazil’s strong export growth for higher profits.

• Using a U.S. dollar loan at 2% interest, the investor converts to Indian rupees and buys high-yield Indian corporate bonds, aiming for better returns while managing the risk of currency changes.

• Borrowing British pounds at a low rate, an investor invests in South African mining stocks, hoping to gain from rising commodity prices but staying cautious of the rand’s volatility.

How does a carry trade work?

Now that we know what a carry trade is let’s dive into how it actually works. 

Picture this scenario: As a financial trader, you find yourself in a unique position where you can secure a loan of one million Japanese yen at an exceptionally low interest rate, let’s say 0.5%. You decide to use this opportunity and convert the borrowed yen into U.S. dollars.

You’re transforming the currency into US Dollars as you’re aware that in the United States, these funds can be invested in bonds yielding a 4% return. Therefore, you use those converted dollars to purchase U.S. bonds.

In this spot, the enchantment unfolds. By lending yen at a rate of merely 0.5%, while simultaneously earning 4% on U.S. bonds, you’re effectively pocketing a difference of 3.5%. This disparity is what’s known as “carry” in the carry trade strategy.

But it’s not just bonds where traders park this money. Some people use the borrowed funds to invest in stocks, aiming for even higher returns. 

Imagine if you exchanged that 1 million Japanese yen into US dollars, then invested those dollars in well-known companies such as Apple or Tesla by purchasing their shares instead.

If those stocks grow by 10% in value, you not only pocket the profits from the stock growth, but also continue to enjoy the advantage of a lower interest rate on your initial investment loan.

For example, if Apple shares go up 10%, and you sell your stocks, the profit from the stock gain could be far higher than what you’re paying in interest on the borrowed yen. 

If the stock prices fall or the yen gets stronger compared to the dollar, your earnings could vanish rapidly, potentially leading to a loss instead.

As a researcher delving into global financial markets, I’ve observed that the practice of carry trades isn’t limited to yen and dollars; it extends across various currencies worldwide. For instance, I’ve noticed that borrowing Swiss francs, which often has low-interest rates, and investing in Australian dollars, known for typically higher interest rates, is another prevalent form of a carry trade.

The strategy remains consistent: secure a loan in a currency with low interest rates, then channel that capital into an investment offering a higher yield in a different currency.

As a researcher studying financial strategies, I’ve found that Carry Trades have gained popularity due to their ability to magnify returns when market conditions are advantageous. However, it’s essential to remember that these trades also carry significant risks. In essence, they’re similar to bending down to pick up pennies while a steamroller is approaching – the opportunity for gain might be alluring, but the potential dangers can be equally substantial.

Impact of Yen carry trade on global markets

For decades, the yen carry trade has been a preferred strategy among investors, primarily due to Japan’s exceptionally low interest rates. The Bank of Japan maintained its key interest rates close to zero for an extended timeframe, occasionally dropping into negative territory at -0.10% since 2016.

Having lived through the economic downturn of the late 2000s, I can attest to the impact of monetary policies designed to stimulate borrowing and boost economic activity. As a small business owner, I have personally experienced the benefits of cheap loans, allowing me to expand my operations and create jobs in my community. However, I’ve also witnessed how these low-interest rates can have far-reaching effects beyond national borders. In Japan’s case, their efforts to stimulate economic activity had global consequences, with lower yields on my savings and increased competition for customers from overseas businesses taking advantage of the cheap borrowing costs. While the intention behind such policies is understandable, it’s essential to consider the unintended consequences they may have on individuals and businesses around the world.

In this scenario, investors are taking advantage of the low-interest rates on the Japanese yen by borrowing it, exchanging it for other high-yielding foreign currencies, and investing those funds in assets offering higher returns overseas.

For example, they could put their money into bond, share, or property markets in nations such as Brazil, Mexico, India, or the United States, where yields are more profitable.

The difference between the low cost of borrowing in Japan and the higher returns on these foreign investments creates profit — a strategy that attracted trillions of dollars over time.

In 2024, however, things took a different turn. Specifically, on March 19, the Bank of Japan increased interest rates for the first time in seven years. Later, on July 31, they hiked rates once more, pushing the key rate to approximately 0.25%, a significant departure from its prior range of 0% to 0.1%.

Although it may appear as a minor adjustment, this shift represented a significant departure from the norm for Japan, given its historically low interest rates over an extended period.

As an analyst, I observed that the recent rate hike led to two immediate impacts. Primarily, it elevated the cost of borrowing yen, thereby diminishing the profit margin associated with the carry trade.

Subsequently, this situation caused the Japanese yen to become stronger compared to other currencies. Consequently, when investors chose to exchange their overseas investments back into yen, they received fewer yen in return than they had previously.

Due to this development, numerous investors started liquidating their carry trades, meaning they sold their overseas investments to repay their yen loans. This large-scale selling caused a chain reaction in international markets.

Investments in stocks, bonds, and various assets supported by yen carry trades started to significantly decrease in worth. This decline was exacerbated by a rapid increase in demand for the Japanese yen, which led to an additional strengthening of the currency. As a result, those who still held foreign assets endured even greater losses.

Risk and rewards

Prior to engaging in carry trades, it’s crucial to carefully consider the benefits versus the possible hazards.

Rewards of carry trades

• Interest rate differentials: The primary reward is the profit from the difference in interest rates between two countries. Borrowing at a low rate and investing at a higher rate allows traders to pocket the difference.
• Potential for high returns: When invested in high-yield assets like stocks, the potential returns can be far higher, amplifying profits beyond just the interest rate spread.
• Leverage: Carry trades often involve borrowing large sums of money, which can magnify profits when the trade works in your favor.
• Steady income stream: When done correctly, carry trades can provide a steady and predictable income stream, especially when interest rates remain stable and favorable.

Risks of carry trades

• Currency fluctuations: A change in the value of the borrowed currency (e.g., yen) can lead to losses when converting back to repay the loan, especially if the borrowed currency strengthens against the invested currency.
• Market volatility: Investments made with borrowed funds, such as stocks or bonds, can decrease in value, potentially leading to losses instead of the expected profits.
• Interest rate changes: If the interest rates in the country where you borrowed money increase, your borrowing costs could rise, reducing or eliminating your profit margin.
• Liquidity risk: In times of market stress, it might be difficult to quickly exit a carry trade without incurring large losses, especially if everyone is trying to do the same thing.

Conclusion

In simpler terms, the latest financial instability, triggered by the reversal of the yen carry trade, demonstrates both its immense power and inherent risks.

Ultimately, carry trades involve finding a delicate equilibrium between risk and return, and it’s crucial to grasp both aspects for shrewd investment choices – this means knowing not only what you stand to gain but also potential losses.
