Is Global Allocation Really Necessary for Your Portfolio?

Do You Actually Need Global vs India Portfolio Allocation?

Should you send your money overseas when Indian markets keep delivering strong returns? This question divides investors sharply. Some say global allocation is non-negotiable. Others call it an unnecessary complication. The truth sits somewhere between these extremes, and it depends heavily on who you are as an investor.

The global vs India portfolio allocation debate has intensified as Indian markets outperformed most developed markets over the past decade. Many Indian investors now question whether they need international exposure at all. Fair question. But asking it the wrong way leads to bad decisions.

1. The Myth: Indian Markets Are Enough

India has been a stellar performer. The Nifty 50 delivered roughly 12 percent annualised returns over the last 20 years. That beats the S&P 500 in rupee terms for several stretches. So the argument goes: why bother with foreign markets?

Here is the problem. You are looking at the past and assuming the future will repeat. India could keep outperforming. It could also hit a rough patch lasting years. Japan was the world's hottest market in the 1980s. Then it went sideways for three decades. No country is immune to prolonged underperformance.

Putting 100 percent of your portfolio in one country, even a fast-growing one, is a concentrated bet. You might win big. You might also sit through painful drawdowns with no counterbalance.

2. The Counter-Myth: You Must Go Global or You Are Doing It Wrong

Some financial advisors push international diversification like it is a universal rule. They point to portfolio theory: uncorrelated assets reduce volatility. True on paper.

But the practical reality for Indian investors is messier:

• Tax complexity. Foreign investments face different capital gains rules, and you may owe taxes in both countries.
• Currency risk. If the rupee strengthens against the dollar, your US investments lose value in rupee terms, even if the underlying stocks went up.
• Higher costs. International funds charge more. Remittance fees add up. TCS on outward remittances bites.
• Correlation is rising. Global markets increasingly move together during crashes. The diversification benefit shrinks exactly when you need it most.

So the blanket advice to "go global" ignores real costs and complications.

3. What the Evidence Actually Shows

Research from Vanguard and other institutions suggests that a home bias of 50 to 80 percent is reasonable for most investors. The optimal split depends on your country's market size relative to the global total.

India makes up about 4 percent of global market capitalisation. By pure market-cap weighting, you should put 96 percent overseas. Nobody serious recommends that. Your liabilities, expenses, and income are in rupees. Matching your assets to your currency makes sense.

A more practical approach: keep 70 to 80 percent in Indian equities and debt. Allocate 20 to 30 percent to international markets. This gives you meaningful diversification without drowning in complexity.

4. Who Benefits Most from Global Allocation

Global allocation is not equally useful for everyone. Be honest about where you fit:

• Large portfolios (above 50 lakh rupees): You have enough scale to justify the extra costs and complexity. Diversification matters more as your wealth grows.
• Tech workers paid partly in dollars: You already have some global exposure through your income. You might actually need less international allocation.
• People planning to emigrate: If you might live abroad, holding assets in that currency makes sense.
• Sector concentration risk: Indian markets are heavy on financials and IT. If you want exposure to global healthcare, semiconductors, or luxury goods, you need to look outside India.

5. Who Can Skip It (At Least for Now)

Not everyone needs global exposure right away:

• Small portfolios (under 10 lakh rupees): The costs and hassle outweigh the diversification benefit. Focus on building your Indian portfolio first.
• Early-stage investors: If you are still learning, adding international complexity is a distraction. Get comfortable with Indian equities and debt first.
• People with short time horizons: If you need the money within 3 to 5 years, currency fluctuations add risk you do not need.

6. The Practical Allocation Framework

If you decide global allocation makes sense for you, here is a simple framework:

These are starting points, not rigid rules. Your personal situation, risk tolerance, and goals should drive the final numbers.

7. The Verdict on Global vs India Allocation

Global allocation is not a myth. It is real diversification with real benefits. But it is also not mandatory for every investor at every stage.

The honest answer: most Indian investors with portfolios above 10 to 15 lakh rupees should have some international exposure. Not because India will fail, but because no single country should hold 100 percent of your financial future.

Start small. One low-cost international index fund at 10 to 15 percent of your portfolio. Increase it as your wealth and knowledge grow. Do not overthink the perfect split. Any reasonable global allocation beats zero global allocation for portfolios of meaningful size.

The biggest risk is not being in the wrong country. It is being in only one country and believing that can never go wrong.
