Halal vs Ethical Investing
What's the Difference?

Ethical investing is everywhere right now. ESG funds, sustainable portfolios, green investments — the marketing is compelling. But for British Muslims, the question is whether ethical investing and halal investing are actually the same thing. They're not — and the difference matters.

What is ethical investing?

Ethical investing is a broad term covering several approaches that aim to align investments with values beyond pure financial return. The most common frameworks are:

ESG (Environmental, Social, Governance)

ESG investing evaluates companies on their environmental impact, social responsibility, and governance standards. A company with poor carbon emissions, poor labour practices, or a corrupt board would score badly on ESG metrics. ESG funds favour companies that score well across these criteria.

SRI (Socially Responsible Investing)

SRI typically involves excluding certain industries entirely — tobacco, weapons, fossil fuels — while seeking out companies that contribute positively to society. It's more exclusion-based than ESG, which tends to be score-based.

What is halal investing?

Halal investing follows Sharia principles derived from Islamic law. It involves screening investments to ensure they are free from prohibited activities and financial structures. The main criteria are:

No riba (interest). Companies whose primary business involves lending money at interest — conventional banks, certain financial services firms — are excluded.

No prohibited industries. Alcohol, tobacco, gambling, weapons, adult entertainment, and pork-related businesses are all screened out.

Debt ratios. Sharia screening also looks at a company's financial structure — companies with excessive conventional debt may fail the screen even if their business activities are otherwise permissible.

Purification. If a company earns a small percentage of income from incidental non-halal activities, that proportion of any returns received should be donated to charity.

Where halal and ethical investing overlap

There is genuine common ground. Both halal and ethical investing typically exclude weapons manufacturers, tobacco companies, and gambling operators. Both tend to favour companies with strong governance and transparent practices. A Muslim investor and an ESG investor would often agree on what to avoid.

Where they differ significantly

CriteriaHalal InvestingESG/Ethical Investing
Conventional banksExcluded (riba)Often included if governance is good
Insurance companiesOften excludedOften included
Alcohol companiesExcludedSometimes included (low ESG impact)
Interest-bearing bondsExcludedCommonly held
Sharia board oversightRequiredNot applicable
Purification processRequiredNot applicable

The biggest difference is conventional financial services. Many ESG funds hold major banks and insurance companies because they score well on governance metrics. For a halal investor, these companies are excluded regardless of their ESG score because their core business involves riba.

Is an ESG fund automatically halal?

No. An ESG label does not equal Sharia compliance. An ESG fund may hold HSBC, Barclays, or Lloyds — all of which would fail a Sharia screen due to their interest-based business models — while still scoring highly on environmental and governance metrics.

Bottom line: ESG and halal investing share some values but use different frameworks. An ESG fund is not a halal fund. Always look for independent Sharia certification, not just an ethical label.

What to look for in a truly halal investment

A Sharia supervisory board. This is non-negotiable. A panel of qualified Islamic scholars should independently oversee and certify the screening methodology.

Clear screening criteria. The platform or fund should publish exactly what it screens for and how — not just say it is "ethical" or "responsible."

Purification process. A credible halal investment platform will calculate and remove any incidental non-halal income, directing it to charity.

FCA regulation. Any UK investment platform should be authorised and regulated by the Financial Conduct Authority. Check the FCA register before investing.
