Understanding Leveraged Investing
Leveraged investing means using borrowed funds to control more assets than you could with only your own money. Imagine trying to lift a heavy object with your bare hands; it might be too difficult. However, with the help of a lever, you can multiply your strength and lift that object much more easily. In the same way, when you use leverage in investing, you increase your buying power by using money that isn’t originally yours. This enables you to invest in larger, more valuable assets while committing only a small portion of your own funds.
The main idea behind leveraged investing is to earn more than what you pay in interest for the borrowed money. If the profits from the investment are higher than the borrowing costs, the extra earnings add up, giving you a net gain. However, this strategy also carries a significant risk: if the investment fails or the market turns against you, the losses can be just as amplified as the gains. Therefore, while leveraged investing can be a powerful tool in the hands of experienced investors, it is not without its dangers.
Warren Buffett’s ingenious Japanese bet
Warren Buffett is a name that resonates with disciplined long-term strategies and smart investment choices. In one of his more unconventional moves, Buffett made headlines with his investment in Japan. On his 90th birthday in 2020, Berkshire Hathaway, the company he leads, announced that it had acquired more than a 5 percent stake in five major Japanese trading companies. These companies are known as “sogo shosha” or general trading companies, and they include names such as Itochu, Mitsui, Mitsubishi, Marubeni, and Sumitomo.
These trading companies are not only significant players in Japan but also crucial contributors to global commerce. They operate in diverse sectors, from energy and metals to consumer goods and infrastructure. The reason behind choosing these companies was not just their prominent market positions, but also the attractive returns they offered.
In his letter to Berkshire Hathaway shareholders, Buffett reflected on his Japanese venture as a prime example of spotting undervalued opportunities. The companies he invested in were not only priced below their global peers, but they also had steady cash flows and attractive dividend yields. Additionally, these firms provided exposure to diverse economic sectors, such as energy, metals, infrastructure, and food. Japan’s low-interest environment and strong corporate governance further enhanced the appeal of this investment.
What made this deal particularly fascinating was Buffett’s financing method, he chose not to use any of his own money for this venture.
The art of Borrowing at a Low cost

Instead of risking his personal capital, Buffett opted for a clever approach: he borrowed money. In Japan, he secured yen loans at a very low interest rate, only half a percent per year. This exceptionally low borrowing cost allowed him to access significant capital without straining his own finances. With the funds obtained through these loans, Buffett made a substantial investment in the Japanese trading companies, totalling around 6.7 billion US dollars.
The genius of this strategy lies in the difference between the low cost of borrowing and the high dividend yields offered by the companies. The trading companies provided dividend returns of roughly 8.5 percent. In simple terms, the income generated from these dividends was far greater than what Buffett paid in interest on the borrowed money. This spread between borrowing costs and dividend income created a situation where the profit was multiplied, and the returns were enormous, all achieved without using Buffett’s own capital.
Unpacking the Deal Structure
Let’s take a closer look at the structure of this ingenious deal. Typically, an investor would use personal funds to make an investment, and the profit would be measured against that invested amount. However, Buffett’s strategy was different. By borrowing money at a very low cost, he could invest a large sum in high-yield assets. The trading companies he chose not only had attractive dividend payouts but also strong fundamentals like stable cash flows and robust corporate governance.
The approach taken by Buffett highlights a few essential elements of leveraged investing:
- Low Borrowing Costs: The key was obtaining loans at a minimal interest rate, which in this case was just 0.5 percent per year.
- High Dividend Yields: The companies provided dividends that were substantially higher—around 8.5 percent, creating a favourable income spread.
- Financial Engineering: By structuring the deal to take full advantage of these factors, Buffett ensured that the earnings from the investment would cover the costs of borrowing and still provide significant profit.
This financial engineering is a testament to Buffett’s skill in capital allocation. His ability to craft a deal that takes advantage of market conditions without risking his own money is one of the reasons he is considered a master investor.
The Evolution of the investment
The progress of Buffett’s investment in Japan over time is nothing short of remarkable. What began as an investment of roughly 5 billion US dollars eventually grew in value to an estimated 12 billion US dollars. This extraordinary growth took place as Japan’s stock market experienced a resurgence, reaching heights that had not been seen in over three decades.
As the value of the investment increased, Berkshire Hathaway doubled down by increasing its stakes in each of the five companies to an average of more than 8.5 percent. Alongside the growth in value, the dividend payments from these companies also saw a significant boost, more than doubling to reach approximately 800 million US dollars annually. This evolution not only underscores the power of leveraging borrowed money but also illustrates how a well-structured investment can multiply returns over time.
One of the most impressive aspects of this strategy is the return on equity. Because Buffett did not use any of his own money in the investment, the profit generated compared to his own capital is, in effect, infinite. This is a clear demonstration of how financial leverage, when applied correctly, can produce outsized returns without the typical constraints associated with investing personal funds.
Key Lessons from Buffett’s Japanese Strategy

Buffett’s Japanese venture offers several important lessons for investors, particularly when it comes to leveraging borrowed money. Below are some of the key takeaways:
1. The Power of other people’s Money
Buffett’s strategy clearly shows how borrowing money at a very low cost and then investing it in high-yield assets can create enormous profit margins. Instead of putting his own money at risk, Buffett used funds borrowed under favourable conditions to generate returns that far exceeded the cost of borrowing. This principle of using other people’s money wisely can be a powerful tool in any investor’s arsenal, but it must be used with caution.
2. Patience and a long-term vision
Another critical lesson from this investment is the importance of a long-term perspective. Despite the inevitable fluctuations in the market, Buffett’s unwavering belief in the potential of the Japanese trading companies allowed him to stay the course. His patience enabled the investment to grow significantly over time. This reinforces the idea that in investing, the focus should be on long-term gains rather than quick, short-term profits.
3. The role of Financial Engineering
Buffett’s ability to structure the deal to maximize returns while minimizing risks demonstrates the importance of financial engineering. By optimizing the capital structure, borrowing at low rates and investing in assets with high dividend yields, he was able to create a highly profitable investment scenario. This careful planning and execution are key elements of value creation and highlight the importance of not just choosing the right investments but also financing them in the most efficient way possible.
Insights from Charlie Munger
Warren Buffett’s long-time business partner, Charlie Munger, also weighed in on this bold move, describing it in enthusiastic terms. Munger referred to the investment as almost a “no-brainer” and compared it to receiving a generous gift. He likened the deal to having a chest of money opened up for you, making it seem as though fortune had smiled upon Berkshire Hathaway. His comments serve to underline the uniqueness and simplicity of the opportunity Buffett seized in Japan.
Munger’s perspective is valuable because it reinforces the notion that sometimes the best opportunities come from recognizing when the odds are overwhelmingly in your favour. In this case, the combination of favourable borrowing conditions, strong dividend yields, and well-managed companies created a scenario where the potential for gain was almost too good to pass up. His remarks also remind us that in the world of investing, timing and a keen eye for opportunities can make a profound difference.
The cautionary side of Leveraged investing
While Buffett’s strategy in Japan is an inspiring example of successful leveraging, it is essential to understand that this method is not a universal blueprint for all investors. Leveraged investing magnifies not only profits but also losses. If the investment were to falter, the downside would be equally magnified, and the investor would still be responsible for repaying the borrowed funds along with the accrued interest.

For most retail investors, the risks associated with leveraged investing can be too high. The strategy requires a deep understanding of market dynamics and the discipline to hold onto an investment over the long term. In Buffett’s case, his extensive experience and comprehensive analysis allowed him to manage these risks effectively. However, for those without similar expertise, leveraging can be a dangerous path that may lead to significant financial losses.
This is why it is important to view Buffett’s Japanese venture as an exceptional case rather than a standard practice for every investor. While it provides valuable lessons on capital allocation and financial strategy, the average investor should approach leveraged investments with caution. A diversified portfolio and a focus on long-term growth are often safer and more reliable strategies for building wealth gradually.
When Leveraging works and when it doesn’t
The key idea behind leveraged investing is to ensure that the returns on your investments exceed the cost of borrowing. In Buffett’s scenario, the dividend yields from the Japanese companies far outweighed the interest payments on the loans. This resulted in a clear profit and a return on equity that was practically limitless because no personal capital was at risk.
However, if market conditions had been unfavourable or if the companies had not performed as expected, the situation could have been drastically different. Losses in such cases would be magnified just as gains were, potentially leaving the investor with a financial burden that could be hard to manage. This dual-edged nature of leverage underscores the importance of understanding the market thoroughly and being prepared for both outcomes.
Lessons for aspiring investors
For those looking to learn from Buffett’s strategy, several key lessons emerge. First, always consider the cost of capital when making an investment decision. Borrowing money at a very low rate can provide a significant boost, but only if the returns on the investment are higher than the borrowing costs. Second, patience is crucial. Market fluctuations are inevitable, but a long-term vision can help smooth out the bumps along the way. Finally, thorough analysis and strategic financial planning, what we call financial engineering, are essential tools for turning opportunities into substantial profits.
Conclusion
Warren Buffett’s investment in Japan is a vivid illustration of how leveraging borrowed money can yield extraordinary returns when executed with precision and care. By borrowing at a very low interest rate and investing in companies with strong dividend yields, Buffett was able to turn an initial commitment of billions into an investment worth nearly twice as much, all without using his own capital. This strategy, which combines smart borrowing, a long-term vision, and meticulous financial engineering, has produced results that stand as a testament to Buffett’s investment acumen.
While not every investor can, or should, follow in Buffett’s footsteps, there is much to be learned from his ability to turn complex financial challenges into opportunities for substantial growth. By understanding and internalizing these lessons, investors can better navigate the intricate world of finance, making informed decisions that balance risk with reward.
However, it is important to remember that leveraged investing magnifies both gains and losses. While Buffett’s experience shows that such a strategy can led to significant rewards, it also highlights the risks involved. For most retail investors, a diversified portfolio with a long-term horizon remains the safest path to steady wealth accumulation. The best strategy is to focus on prudent, long-term growth rather than chasing high-risk, high-reward manoeuvres.
