If you want to invest in the S&P 500 from India, there is more than one way to do it. You can buy an Indian index fund in rupees, buy an S&P 500 ETF listed on the NSE, or remit money abroad under LRS and buy a US-listed or UCITS ETF directly.
Most investors end up narrowing this down to a choice between two: the Motilal Oswal S&P 500 Index Fund, the largest rupee route, and a UCITS S&P 500 ETF like CSPX, the most popular direct route.
The Motilal Oswal S&P 500 Index Fund is an Indian mutual fund that holds the S&P 500 constituent stocks directly, in proportion to their index weights. It was launched in April 2020, is bought in rupees with a minimum investment of Rs 500, and manages around Rs 4,487 Cr.
The iShares Core S&P 500 UCITS ETF (CSPX) is an Ireland-domiciled ETF that also holds the S&P 500 stocks directly. It was launched in 2010, manages over $151 billion, and reinvests all dividends automatically. Indian investors buy it in dollars through the RBI's Liberalised Remittance Scheme (LRS) and hold the units directly in their own name.
Both give you the same 500 companies, but the underlying costs are not the same. This comparison walks through why the gap is there, what it costs you in practice, and when the convenience of staying in rupees is still worth it.

What both routes give you
- The same index. Both track the S&P 500, the 500 largest listed companies in the US across every major sector.
- Direct stock ownership at the fund level. Neither route wraps you in a fund-of-fund structure. The Motilal Oswal fund holds the underlying stocks itself, and so does CSPX.
- No US estate tax exposure. Neither route holds US-listed securities in your name. The Motilal Oswal fund is an Indian mutual fund, and Ireland-domiciled UCITS ETFs are exempt from the US estate tax that applies to US-listed ETFs above USD 60,000.
So the choice is not about the index, the structure, or estate tax. It is about currency, cost, access, and compliance.
The structural difference: rupee mutual fund vs dollar ETF
The Motilal Oswal fund is bought and held in rupees. Your money never leaves India, and you never deal with foreign exchange or LRS.
CSPX is bought and held in dollars. You remit money abroad under LRS and buy the ETF on an exchange such as the London Stock Exchange, and the units sit in your own brokerage account with a global custodian.
This currency and access difference is what drives the cost, tax, and compliance differences covered next.
Cost comparison
Both funds hold the stocks directly rather than investing through another fund, so the cost comparison here is simple: just each fund's own expense ratio.
| Cost item | Motilal Oswal S&P 500 Index Fund | iShares Core S&P 500 UCITS ETF (CSPX) |
| Expense ratio | 0.58% (direct) / ~1.06% (regular) | 0.07% TER |
| Exit load | 1% if redeemed within 7 days | None |
| One-time costs | None | Remittance and FX conversion charges, brokerage |
Even the direct plan costs more than 8 times CSPX's TER.
Performance: how each fund tracks its index
The Motilal Oswal fund discloses an annualised tracking error of 0.2% against the S&P 500 TRI. That gap comes mostly from its expense ratio, plus minor cash drag from the small liquidity buffer it holds.
CSPX has actually outperformed its stated benchmark every calendar year from 2016 to 2025, by roughly 0.2 to 0.3 percentage points annually.
This is not unusual for large physically-replicated UCITS funds: securities lending income and Ireland's lower withholding tax rate on US dividends more than offset the 0.07% fee, so the realised gap runs in the fund's favour rather than against it.
As with any INR-vs-USD comparison, rupee depreciation inflates the Motilal Oswal fund's INR returns the same way it would inflate yours in the UCITS route, so raw return numbers are not a fair basis for comparison. Tracking error against each fund's own benchmark is the honest measure.
Why does the fund keep restricting subscriptions?
SEBI caps the entire Indian mutual fund industry's overseas investments at USD 7 billion. When the industry hits the cap, fund houses must stop taking fresh money.
The Motilal Oswal S&P 500 Index Fund has lived inside this constraint since January 2022, when it was suspended alongside the AMC's other overseas schemes. It reopened in December 2022 at a cap of Rs 2 lakh per PAN per month for lumpsum and switch-in investments, while SIP restrictions continued separately.
In January 2025, the AMC paused fresh SIP inflows into this fund again, grouped with its Nasdaq 100 Fund of Fund and MSCI EAFE fund, citing exhausted overseas headroom.
What this means for you in practice:
- Fresh lumpsum investments and new SIP registrations get paused when the industry cap is breached, and even after reopening, lumpsum deployment stays capped at Rs 2 lakh per PAN per month.
- Already-running SIPs have been paused in some suspensions and allowed to continue in others. Check the specific addendum in effect at the time rather than assuming either way.
- Whether fresh investment reopens next month depends on other investors redeeming, which you cannot predict.
The UCITS route does not have this problem. Your LRS limit of USD 250,000 per financial year is your own individual limit under RBI rules. It does not depend on what other investors do.
Already hold the fund? What switching involves
If you already hold the Motilal Oswal fund, switching is a decision to make deliberately, not in a rush. Three things to know:
1. Redeeming triggers capital gains. Selling your units is a taxable event. Units held over 24 months are taxed at 12.5% LTCG; units held under 24 months are taxed at your slab rate. If you have large short-term gains, it may be worth waiting for them to turn long-term before moving.
2. There is no in-kind path from a mutual fund. Mutual fund units cannot be transferred to a foreign brokerage. The only path is redeem, remit, and repurchase. You can stagger this over months to average out currency conversion and market timing, and to stay within any TCS thresholds you care about.
3. The exit load window is short but real. A 1% exit load applies only within the first 7 days of allotment, so most existing holders will not face it. But check your allotment dates unit by unit before redeeming, since SIP installments each carry their own 7-day clock.
Taxation in India: nearly identical
For Indian residents, the tax treatment of the two routes is close.
| Motilal Oswal S&P 500 Index Fund | UCITS S&P 500 ETF | |
| Long-term holding period | 24 months | 24 months |
| LTCG rate | 12.5% | 12.5% |
| STCG rate | Slab rate | Slab rate |
| Taxed only on redemption | Yes | Yes (accumulating ETF, no dividend income) |
| Schedule FA disclosure | Not required | Required every year you hold |
| TCS on investment | None | 20% on LRS remittances above Rs 10 lakh per year, adjustable against tax |
The genuine difference is compliance, not rates. The Motilal Oswal fund requires nothing beyond your normal ITR. The UCITS route requires you to disclose your foreign holdings in Schedule FA every year, and non-disclosure carries significant penalties under the Black Money Act.
Ownership and portability
One more difference matters if you have plans to move overseas.
The Motilal Oswal fund is an Indian mutual fund holding, in rupees, inside the Indian mutual fund system.
If you move abroad, you can usually continue holding, but fresh investments as an NRI depend on the fund house's policy for your country of residence, and US and Canada-based NRIs face particular restrictions. If you become a US person, Indian mutual funds are also classified as PFICs, triggering punitive US tax treatment and annual Form 8621 filing.
CSPX units are held in a global brokerage account in your name. If you move from India to Dubai, Singapore, or London, the holding moves with you: you update your residency with the broker and carry on.
If you might become an NRI, this portability can matter more to your decision than the cost comparison, though US-based NRIs should note that UCITS funds face their own PFIC treatment once you become a US person.
Which route is right for you?
The Motilal Oswal route fits you if:
- You invest small amounts monthly in rupees
- You want zero paperwork and no foreign disclosure
- You can live with the subscription caps
The UCITS route fits you if:
- You are investing a meaningful corpus
- You care about the recurring cost gap compounding over a decade
- You don't want to be subject to arbitrary investment limits and pauses
- There is any chance you will live outside India
Neither route is wrong. But the cost gap here is wide enough that even a small monthly SIP investor should know what they are giving up for the convenience.
Switching to Paasa
If you have decided to move some or all of your S&P 500 exposure from the Motilal Oswal fund to a UCITS ETF, Paasa handles the parts that usually cause friction:
- Access to US, European, and other global markets: You can add US-listed stocks, European UCITS ETFs, and other international assets from the same account.
- Seamless funding and LRS: Remit, convert, and buy the UCITS ETF in one flow, with LRS compliance handled within the platform.
- Compliance advantage: Get all Indian tax and disclosure documents generated for you at tax time.
