How Much Foreign Equity Exposure Does an Indian Investor Really Need?

A working guide for Indian equity investors  ·  August 2026

Executive summary

For most Indian equity investors, somewhere between 15% and 25% of the portfolio makes sense as a foreign allocation, and 20% is a reasonable place to default to. The case for going abroad at all is straightforward: an India-only portfolio is exposed to one economy, one currency and one market cycle at the same time, with nothing to pull the other way when any of the three has a bad run. Where investors tend to go wrong isn't the headline number, though — it's the details underneath it: assuming “international” just means the S&P 500, underestimating what SEBI's caps and fund costs do to the mutual-fund route, or missing that the tax rules on these funds have changed twice in two years. This report works through each of those in turn, and closes with a view on who should sit above or below the 20% default.

Why look beyond India at all

Hold only Indian stocks and an investor isn't just betting on India's growth, which is the good part — they're also tying their returns, their currency and their market cycle to the same economy, all at once. If Indian equities go through a rough patch, nothing else in the portfolio is there to pull the other way. Foreign equities are the most direct way to loosen that knot. The real questions are how much of the knot actually needs loosening, and whether the loosening has to mean buying the US.

The 20% question

There's no universally correct number here, but a workable range for most Indian portfolios looks something like this. Around 10% is a token gesture towards diversification — better than nothing, but not enough to change how the portfolio behaves in a bad year. Somewhere near 20% is where it starts to matter: currency exposure, sector mix and India-dependence all shift in a way an investor would actually notice. Past 30%, an investor is making a real statement about global markets relative to India, and that call deserves its own reasoning rather than an extension of the same logic.

Vanguard's research is a useful reference point. Its paper “Global equity investing: The benefits of diversification and sizing your allocation” finds that a US investor captures more than 95% of the available diversification benefit by putting 30%–40% of their equity into international stocks. It would be a mistake to import that number wholesale into an Indian portfolio, though — the research is built around a US starting point, and India's is different.

Indian equities are already less correlated with the rest of the developed world than developed markets are with each other, so a rupee portfolio is doing some of that diversification work on its own before a single foreign share is bought. On top of that, going much past 25–30% starts running into frictions — regulatory limits, tax treatment, cost — that a US investor simply doesn't have to think about. Those frictions end up shaping the practical answer more than any diversification formula does, and the rest of this report walks through them properly.A simple way to think about it

Does going international just mean buying the US?

The US deserves to be the core of most international allocations — it has the world's deepest equity market and an unusual concentration of the biggest technology, healthcare, consumer and financial businesses, many of which already earn a large share of their revenue outside America anyway.

But US exposure and global exposure are two different things, and it's easy to conflate them. An investor putting 20% of their portfolio into an S&P 500 fund has diversified away from India. They have not diversified across the rest of the world.

The rest of the world adds things the US doesn't fully capture: Europe brings industrials, pharmaceuticals, luxury goods and financials; Japan brings automation, precision manufacturing and the auto industry; emerging markets — Taiwan, South Korea, China, Brazil — bring a growth and risk profile that looks nothing like either. The point isn't to own every country on earth. It's to avoid quietly making one foreign market the entire international allocation, which is exactly what an all-US foreign sleeve ends up being.

A simple way to picture it

Take a portfolio with ₹1 crore in equities and a 20% foreign allocation — that's ₹20 lakh going abroad. One reasonable way to split it:

Region	Illustrative weight within a 20% foreign allocation	On a ₹1 crore equity portfolio
United States	12%	₹12 lakh
Europe	4%	₹4 lakh
Japan	2%	₹2 lakh
Emerging markets (ex-India)	2%	₹2 lakh
Total foreign equity	20%	₹20 lakh

The US is still the biggest single piece here, which is fine — it's supposed to be. But the rest of the allocation is actually doing something, rather than just being a second, foreign version of the same concentrated bet.

At a smaller allocation, this kind of split stops making much sense. If the same ₹1 crore portfolio carried only a 10% foreign weight — about ₹10 lakh — dividing that across four regional funds would mostly just add paperwork. A single broad global fund, one that already blends developed and emerging markets and lets the US fall out as the largest holding on its own, does the job more simply and more cheaply. The four-way split starts earning its keep once the allocation itself is big enough — roughly 20% and up — for each regional slice to actually be a position, rather than a rounding error.

The currency argument, quantified

Foreign equities bring currency diversification along with them. Money held in dollars gives an Indian investor an extra return driver whenever the rupee weakens against the dollar, and takes one away when the rupee strengthens instead.

It's worth putting a number on this rather than leaving it as a vague gesture at “currency risk.” Over the last two decades or so, the rupee has slid against the dollar by something like 3–4% a year on average — from around ₹44 to the dollar in 2005 to roughly ₹88–90 today. That slide hasn't been smooth: there have been long stretches of relative calm, and a few periods where the rupee actually firmed up. But applied to a foreign holding, that average depreciation adds up — an investment returning 8% in dollar terms would have come back looking more like 11.5%–12% once converted into rupees, in a year when the rupee weakened by that much. None of this is a promise about the future; a strong-rupee year would take a bite out of returns instead. But it's a real, quantifiable reason the currency argument isn't just hand-waving.

It matters most for goals that are genuinely denominated in another currency — a child heading overseas for university, a retirement spent partly abroad. For those, holding dollars isn't just diversification. It's matching the asset to the bill that's eventually going to arrive.

How much is too much?

Past a certain point, a foreign allocation stops being about diversification and starts being a view. A 40% weighting to international stocks needs a considerably better argument behind it than a 15% one does, because at that size an investor is making a real call on relative valuations, currencies and global growth — not just smoothing out India-specific risk. Three things make that case progressively harder as the number climbs.

The regulatory ceiling

The first constraint is regulatory. SEBI limits how much Indian mutual funds can send overseas in total — currently US$7 billion across the industry, with a further cap of US$1 billion per fund house, and a separate US$1 billion ceiling for international ETFs. There's a workaround: the GIFT City IFSC route offered through domestic brokerages. But that still falls under the RBI's Liberalised Remittance Scheme, which limits an individual to US$250,000 of foreign investment a year and applies a 20% tax collected at source on anything remitted for investment beyond ₹10 lakh in a year.

This isn't a hypothetical constraint. Through much of 2026, several large fund houses have had to pause fresh SIPs and lump-sum investments into their international schemes simply because they're bumping up against these caps, leaving only a handful of funds open to new money at any given moment. Anyone building a foreign allocation through mutual funds should check that the specific fund they want is actually accepting money, rather than assuming it always will be.

Tax, cleaned up

Second is tax, and it's worth getting right because the rule has shifted twice in recent years. Back in 2023, these funds were briefly taxed at slab rate no matter how long they were held, which was a real disincentive. Budget 2024 walked that back for equity-oriented international funds — the harsher rule now only applies to funds that hold mostly debt. Today, the treatment mirrors a foreign stock bought directly: hold the units for 24 months or less and gains are taxed at the investor's slab rate; hold them longer and it's a flat 12.5%, with no indexation.

That means the tax rate itself isn't much of a reason any more to prefer the mutual-fund route over investing directly through LRS or GIFT City — both land in the same place. What's still missing from both routes is the ₹1.25 lakh annual exemption that domestic listed equity gets. And for anyone holding older units bought under the earlier rules, it's worth checking with a tax advisor how they'll actually be treated on sale.

The cost layer

Third, and less talked about, is cost. Most Indian “international mutual funds” are fund-of-funds — an Indian scheme that in turn buys units of a foreign master fund — which usually means paying twice: the Indian fund's own expense ratio, stacked on top of whatever the underlying foreign fund already charges. All-in, that can easily run past 1% a year, against well under 0.5% for an ordinary domestic index fund. It's a quiet drag rather than a dramatic one, but it compounds over a couple of decades, and it's the strongest practical argument for the direct or GIFT City route once an investor is comfortable with the extra paperwork that comes with it.

Who the default suits, and who it doesn't

Twenty percent is a starting point, not a rule, and it's worth being explicit about which way an investor should move off it. Lean higher, towards 25–30% or more, with a long investment runway and a genuine appetite for risk, or with a concrete foreign-currency goal such as a child's education abroad — especially once comfortable investing directly and able to sidestep the fund-of-funds cost layer altogether. Lean lower, towards 10–15%, when the major goals are mostly rupee-denominated and closer at hand — retirement in India, a house — particularly if the only realistic route available is a high-cost feeder fund, or if the preferred fund happens to be closed to new money right now.

The bottom line

The underlying idea is simple, even if the mechanics around it aren't: investing abroad should reduce concentration, not just relocate it. Putting a chunk of a portfolio into an S&P 500 fund and calling it a day trades one concentrated bet for another; the actual point of going global is to spread the risk, not just move it to a different postcode.

If a single number is unavoidable: 20% of the equity portfolio is a reasonable place to start for most Indian investors — enough to meaningfully dilute India- and rupee-concentration, without picking a fight with regulatory caps, tax quirks or fund costs that get progressively harder to justify past 30%. Anyone just starting out can begin smaller, around 10%, and build from there as the rest of the picture becomes clearer.
