The National Stock Exchange of India (NSE) is the larger and more liquid of India's two main stock exchanges, accounting for roughly 90 percent of daily equity trading volume in the country. The Nifty 50 is its benchmark index, equivalent to the S and P 500 for India. Total market cap of NSE-listed stocks sits around 440 trillion rupees, which is about 5.3 trillion dollars as of early April 2026. That makes India the fourth-largest equity market in the world by market cap.

For Shariah investors, the NSE offers the Nifty 50 Shariah Index and the Nifty 500 Shariah Index, both maintained by NSE Indices Limited in partnership with IdealRatings for the screening methodology. The Nifty 50 Shariah tracks the subset of Nifty 50 stocks that meet Shariah criteria, typically around 27 to 32 of the 50 parent constituents. The Nifty 500 Shariah covers a broader universe of roughly 200 to 250 names.

Let me compare the Nifty 50 Shariah with the BSE 500 Shariah and walk through the differences.

Methodology differences

The Nifty 50 Shariah uses IdealRatings as the screening partner. IdealRatings applies AAOIFI-inspired thresholds for debt-to-market-cap, cash-to-market-cap, and non-compliant income. The key difference from the BSE approach is that Nifty uses market cap as the denominator for debt and cash ratios, while BSE has historically used total assets.

In practice, for large-cap Indian stocks, the market cap denominator tends to be more generous because Indian companies often trade at high valuations relative to book value. A stock with a debt ratio that looks problematic against total assets can look clean against market cap. This means the Nifty Shariah universe includes a few names that might fail stricter BSE screens, and vice versa.

The business activity screens are nearly identical between the two methodologies. Conventional banking, insurance, alcohol, tobacco, gambling, adult entertainment, pork, and weapons of mass destruction are all excluded.

Nifty 50 constituents that are Shariah-compliant

The Nifty 50 is dominated by a handful of sectors: IT services, banking, consumer goods, energy, and pharmaceuticals. Of the 50 stocks, the ones that typically pass Shariah screens include:

Reliance Industries (RELIANCE.NS) (check debt ratio quarterly)
Tata Consultancy Services (TCS.NS)
Infosys (INFY.NS)
HCL Technologies (HCLTECH.NS)
Wipro (WIPRO.NS)
Tech Mahindra (TECHM.NS)
Larsen and Toubro (LT.NS)
Bharti Airtel (BHARTIARTL.NS) (check debt)
Hindustan Unilever (HINDUNILVR.NS)
ITC (ITC.NS) (excluded under stricter screens due to tobacco)
Nestle India (NESTLEIND.NS)
Asian Paints (ASIANPAINT.NS)
Maruti Suzuki (MARUTI.NS)
Tata Motors (TATAMOTORS.NS)
Mahindra and Mahindra (M&M.NS)
Bajaj Auto (BAJAJ-AUTO.NS)
Eicher Motors (EICHERMOT.NS)
Sun Pharmaceutical (SUNPHARMA.NS)
Dr. Reddy's Laboratories (DRREDDY.NS)
Cipla (CIPLA.NS)
Titan Company (TITAN.NS)
Ultratech Cement (ULTRACEMCO.NS)
Tata Steel (TATASTEEL.NS)
Hindalco Industries (HINDALCO.NS)
Coal India (COALINDIA.NS)
Divi's Laboratories (DIVISLAB.NS)

That gives you around 26 large-cap Shariah-compliant names in the Nifty 50 universe. The excluded names are almost entirely financials: HDFC Bank, ICICI Bank, Kotak Mahindra Bank, State Bank of India, Axis Bank, IndusInd Bank, Bajaj Finance, Bajaj Finserv, and HDFC Life Insurance. Together, these financial exclusions represent roughly 35 to 40 percent of the Nifty 50 index by market cap, which is a huge underweight for any halal portfolio.

The telecom question

Bharti Airtel (BHARTIARTL.NS) is interesting because it sits in a borderline zone. Market cap around 9 trillion rupees. The company has substantial debt from spectrum auctions and network expansion, and its debt-to-market-cap ratio has historically oscillated between 25 and 40 percent. Under the Nifty 50 Shariah methodology which uses market cap as the denominator, Bharti sometimes passes and sometimes fails. Under stricter total-assets methodologies, it more consistently fails.

Reliance Jio, Bharti Airtel's main competitor, is owned by Reliance Industries rather than being separately listed. That means you cannot get pure mobile telecom exposure in India through a halal-screened listed stock reliably. Vodafone Idea is a third carrier but has been heavily indebted and fails screens.

Cases where Nifty Shariah and BSE Shariah disagree

A few mid-cap names flip between compliant and non-compliant depending on which methodology is applied:

Reliance Industries is borderline under some methodologies and clean under others
Tata Motors has fluctuated based on JLR debt consolidation
Bharti Airtel has had similar issues
Mahindra and Mahindra has had quarters where its financial services subsidiary (Mahindra and Mahindra Financial Services, MMFS.NS) consolidation pushed the parent's ratios into non-compliant territory

For a conservative halal investor, the safer approach is to require that a stock pass under both Nifty Shariah and BSE Shariah before buying. That intersection is smaller but more strong.

The Nifty IT sub-index

If you want pure IT services exposure, the Nifty IT sub-index is effectively all Shariah-compliant. It tracks the 10 largest Indian IT services companies, and all of them pass halal screens. You can replicate this sub-index by owning TCS, Infosys, HCL Technologies, Wipro, Tech Mahindra, LTIMindtree, Mphasis (MPHASIS.NS), Persistent Systems (PERSISTENT.NS), Coforge (COFORGE.NS), and L and T Technology Services (LTTS.NS). All 10 are compliant.

Indian IT services is arguably the single best halal sector exposure available in any emerging market. The businesses serve global enterprise customers, generate US dollar revenue with lower currency risk than pure Indian rupee exposure, and operate with minimal debt because software services is a capital-light business. Margins run 20 to 25 percent, return on equity exceeds 25 percent for most names, and dividend yields are modest but growing.

A practical halal Nifty portfolio

If you want to build a halal portfolio that tracks the Nifty 50 as closely as possible while staying compliant, the core holdings would be:

TCS (TCS.NS)
Infosys (INFY.NS)
Reliance Industries (RELIANCE.NS) (check ratios)
HCL Technologies (HCLTECH.NS)
Larsen and Toubro (LT.NS)
Hindustan Unilever (HINDUNILVR.NS)
Sun Pharmaceutical (SUNPHARMA.NS)
Maruti Suzuki (MARUTI.NS)
Mahindra and Mahindra (M&M.NS)
Ultratech Cement (ULTRACEMCO.NS)
Asian Paints (ASIANPAINT.NS)
Titan Company (TITAN.NS)
Coal India (COALINDIA.NS)
Nestle India (NESTLEIND.NS)
Bajaj Auto (BAJAJ-AUTO.NS)

That is 15 names covering roughly 50 percent of the Nifty 50 by weight. Adding Wipro, Tech Mahindra, Dr. Reddy's, Cipla, Divi's, Eicher Motors, Tata Steel, Hindalco, and Tata Motors takes you to about 60 to 65 percent of the index by weight and gives solid sectoral balance.

Access and ETFs

The NSE is accessible to foreign investors through Foreign Portfolio Investor accounts. Several US-listed ETFs provide indirect exposure, including iShares MSCI India ETF (INDA), Franklin FTSE India ETF (FLIN), and WisdomTree India Earnings Fund (EPI). None are Shariah-screened.

For Shariah-screened exposure, the iShares MSCI Emerging Markets Islamic ETF (ISEM.L) on the London Stock Exchange holds Indian names including TCS, Infosys, and Reliance Industries. It trades in London and is accessible to European investors more easily than US residents.

Bottom line

The Nifty 50 Shariah and the BSE 500 Shariah are both good starting points for building a halal Indian portfolio. The Nifty version is more liquid and better for institutional investors, while the BSE 500 offers broader mid and small-cap exposure. IT services, pharmaceuticals, and consumer goods are the sectors that give the cleanest halal exposure. The biggest exclusion is the Indian banking sector, which represents roughly 35 to 40 percent of the Nifty 50 and is entirely off-limits. Build a halal Indian portfolio around 15 to 20 names from the Shariah-compliant subset of the Nifty 50, with supplementary positions in mid-cap IT services and pharma names if you want broader diversification.
