The Problem with an All-Indian Portfolio
It’s natural for investors to favor what they know. This tendency, known as "home bias," means many Indian portfolios are heavily concentrated in domestic stocks and bonds. While investing in India's growth story is compelling, putting all your financial
eggs in one geographic basket exposes you to significant concentration risk. Your entire net worth becomes tethered to the Indian economy's performance, local political events, and domestic regulatory changes. If the Indian market faces a downturn, a portfolio without international exposure has nowhere to hide. This is the core problem that global diversification aims to solve: to reduce your dependency on a single country's economic cycle.
The Promise of Going Global
The primary benefit of international investing is spreading your risk across different economies that don't always move in the same direction. When the Indian market is sluggish, markets in the US, Europe, or other emerging economies might be booming, and vice versa. This lack of perfect correlation can help smooth out your portfolio's returns over time. Furthermore, investing abroad gives you access to industries and world-leading companies that may not have equivalents listed on Indian exchanges, such as certain global tech giants, specialized manufacturers, or innovative healthcare firms. For instance, if you want to invest in the growth of semiconductors or global social media platforms, you often need to look beyond domestic markets. This is the upside: you reduce home-market concentration and tap into a wider universe of opportunities.
Trading One Set of Risks for Another
Here is the crucial point the headline makes. While you’ve successfully reduced home-market risk, you’ve simultaneously invited a new set of risks to your portfolio. The most significant of these is currency risk. Your returns on a US stock, for example, depend on both the stock's performance and the INR-USD exchange rate. If the stock gains 10% but the rupee strengthens by 8% against the dollar, your actual gain in rupee terms is significantly eroded. Conversely, a depreciating rupee can amplify your gains, but this volatility adds a new layer of unpredictability. Beyond currency, you also face geopolitical risks, differing regulatory environments, and the challenge of staying informed about companies thousands of miles away.
The Great Convergence During a Crisis
The biggest challenge to the idea that international diversification slashes overall risk comes during major global crises. Research and historical events, like the 2008 financial crisis and the 2020 pandemic-induced crash, show that in times of widespread panic, correlations between global markets increase dramatically. When investors are fearful, they often sell assets across the board, and markets that once moved independently suddenly fall in unison. This phenomenon, known as contagion, means that the diversification benefits you enjoy in normal times can evaporate just when you need them most. So, while your portfolio is no longer just an India-risk portfolio, it becomes a global systemic-risk portfolio, which isn't necessarily less risky, just different.
A Smarter Way to Diversify
This doesn't mean international investing is a bad idea—far from it. It simply means you must approach it with open eyes. The goal of global diversification is not to eliminate risk, but to manage it by swapping concentrated domestic risk for a basket of diversified global risks. The key is understanding these new risks. Investors should consider the role of currency, the potential for increased correlation during downturns, and their own long-term goals. Allocating a sensible portion of your portfolio, perhaps 15-30%, to international assets can provide a healthy balance, allowing you to participate in global growth while maintaining a strong anchor in the domestic economy you know best.
