A stock exchange for doing good
A normal stock exchange connects companies that need money with investors who want a financial return. A Social Stock Exchange (SSE) connects social enterprises with funders who want a social return — and sometimes a small financial one too.
The catch is that social return is harder to see than profit. That is why the SSE needs rules, reports and Social Impact Assessors like you.
Where SSEs started
The first SSE was launched in Brazil in 2003. Others followed:
| Country | Year |
|---|---|
| Brazil | 2003 |
| South Africa | 2006 |
| Portugal | 2009 |
| Canada | 2013 |
| Singapore | 2013 |
| United Kingdom | 2013 |
| Jamaica | 2019 |
Of these seven, only three still function — in Canada, Singapore and Jamaica.
Two global models
The workbook describes two models of SSE:
- Matchmaking platform — a separate platform, away from existing exchanges, that brings investors and investees together.
- Alternative investment instruments listed on an existing stock exchange.
Matchmaking platforms usually serve either for-profit enterprises or non-profits — no country had a comprehensive solution for both.
| Platform | Serves |
|---|---|
| Brazil's BVSA (Socio-Environmental Impact Exchange) | NPOs |
| South Africa's SASIX (Social Investment Exchange) | NPOs |
| UK's Social Stock Exchange | FPEs |
| Canada's Social Venture Connexion | FPEs |
For NPOs, these platforms offered only discovery — no new instruments — so they attracted few investors. The Canadian platform was discovery only, with no trading. The UK platform allowed very limited trading.
Singapore's Impact Investment Exchange (IIX) trades impact-related securities like the Women's Livelihood Bonds. These are not strictly pay-for-success — they promise a financial return even if social impact is not created. Its limitation: it appears to serve only FPEs, with no systematic route for NPOs.
India's SSE
In India the SSE is a separate segment of existing recognised stock exchanges — NSE SSE and BSE SSE. The whole ecosystem is regulated by SEBI.
The formal definition:
Three points to hold on to:
- Both NPOs and For Profit Social Enterprises can raise funds.
- An NPO may simply register on the SSE without raising funds.
- Social intent must be the first and primary objective of every social enterprise that plans to list.
The SSE framework asks social enterprises to demonstrate social impact intent, define the outcomes they seek, and report the impact achieved. It also requires disclosures on governance, funding, legal compliance and social impact performance.
Why an SSE? The rationale
India already funds its social sector through CSR, impact investment, philanthropy and regular giving. But social enterprises do not access these resources uniformly. The SSE bridges the gap between the private sector and the non-profit sector, channelling more capital to both FPSEs and non-profits.
Objectives
The workbook quotes this objective:
A major objective is to promote transparency and accountability in the flow and use of funds.
Functions
Keep objectives and functions apart — the workbook's own sample question tests exactly this.
- The SSE lists funding channels and provides procedures and guidelines that act as a filter, letting in only organisations that demonstrate and report social intent.
- Standardisation of procedures could be its key basic function.
- Its secondary function is the set of frameworks of procedures, guidelines and code of conduct.
Who is on the SSE — the stakeholders
The workbook lists: Trading Members, NPOs, For Profit Social Enterprises, Market Infrastructure Institutions, Social Impact Assessors, Information Repositories, Regulators and Investors. Under the ICDR Regulations, an SSE must be accessible to institutional, non-institutional and retail investors.
Trading members
Members of an exchange who trade for themselves or clients. Each gets a trading member ID; each user must be registered with the SSE and gets a unique user ID. Through them, individuals buy securities of NPOs and FPEs, and they provide platforms for ASBA and UPI-based donations.
| Type | What they do |
|---|---|
| Clearing member | Risk management; confirmation / inquiry of trades |
| Trading cum clearing member | Trades for self and clients; clears and settles for self and others |
| Professional clearing member (PCM) | A clearing member who is not a trading member — typically banks and custodians |
NPOs and FPEs
The workbook sizes the sector:
- At least 33 lakh NPOs in India (Central Statistical Institute of India) — about one for every 400 Indians
- More than 1.5 million non-profits in the United States (NCCS)
- GiveIndia reports eight causes: children, differently abled, education, elderly, livelihoods, health, women, environment
The 2019 Bain & Company philanthropy report: India accounts for more than 20% of the world performance gap in 10 of the 17 SDGs, and more than 10% in the rest. That is a funding gap of about ₹4.2 lakh crore a year to meet only 5 of the 17 SDGs by 2030.
Tax. All NPOs must be registered under Section 12A of the Income Tax Act, 1961 and file returns. An NPO can offer donors a tax deduction after approval under Section 80G.
Where NPO money comes from. About 70% comes from four sources: individual donations, FCRA contributions, CSR grants and government scheme grants. Large NPOs benefit most. As of 2018, only 1.8 lakh institutions had registered and claimed tax exemption. Of them only about 12% had FCRA funding and 11% had CSR funding.
The starvation cycle. Institutional donations that are not tax-deductible can usually be spent only on programmes. Rent, utilities, staff training and research must come from the NPO's own pocket. So NPOs cannot invest in their own infrastructure, and growth stalls.
FPEs list equity subject to listing requirements covering financial reporting, governance and social impact reporting — the minimum reporting standard. The exchange identifies them clearly as For Profit Social Enterprises, distinct from ordinary companies.
Section 8 companies (Box 2.2). They can organise on a share basis, but cannot pay dividends, so the shares are not residual claims on profit. There is no regulatory hurdle to listing their shares or debt — they simply have not used it, because they cannot give financial returns.
Social Impact Assessors
Under the ICDR Regulations, a "Social impact assessor" means an individual registered with a self-regulatory organization under ICAI or such other agency as SEBI specifies, who has qualified a certification program conducted by NISM and holds a valid certificate.
- They perform independent verification of impact reporting.
- Social impact assessment is mandatory for entities on the SSE.
A Social Impact Assessment Organisation is an entity that has either:
- employed SIAs and has a track record of at least 3 years in social impact assessment, or
- employed at least two full-time SIAs, each with at least 3 years' experience, who sign the report.
The code of conduct covers integrity, objectivity, confidentiality, professional behaviour, professional competence and due care, documentation, due diligence and compliance.
Information Repositories (IRs)
IRs do three jobs: enumeration (listing active NPOs), standardisation (a standard reporting format) and verification (due diligence). They exist because there is a dire lack of robust information on NPOs. They act as a "feeder" to the SSE.
NGO DARPAN is run by NITI Aayog with the Ministry of Home Affairs and the Ministry of Electronics and IT. It holds self-declared data on over 320,000 NPOs and gives NGOs a unique ID essential for government grants. Private repositories include GuideStar India, GiveIndia and Credibility Alliance.
Regulator, SROs and the Governing Council
SEBI regulates SSEs and created the new class of social impact assessors. Assessors register with an SRO:
| SRO | Parent body |
|---|---|
| Institute of Social Auditors of India (ISAI) — a Section 8 company | ICAI |
| ICMAI Social Auditors Organization (ICMAI SAO) | Institute of Cost Accountants of India |
| ICSI Institute of Social Auditors (ICSI ISA) | Institute of Company Secretaries of India |
Other bodies in the evolution of social impact assessment: Ministry of Rural Development, CAG, Social Audit Unit, Ministry of Corporate Affairs.
Every SSE must constitute a Social Stock Exchange Governing Council (SGC) with balanced representation — donors, NPOs, Information Repositories, social impact investors and others. It oversees registration, fund raising and disclosures.
Investors and communities
Investors split into institutional and non-institutional. On the SSE, one group is outcome funders (wanting impact in the same sector) and the other is risk investors. The primary stakeholders are the communities / target groups — underserved populations and lagging regions.
Funding structures — the heart of the chapter
The basic divide: FPEs can raise equity. NPOs cannot — equity is a claim on profits, and NPOs do not make profits for owners. The exception is Section 8 companies, which can issue shares (but pay no dividends).
Routes for NPOs
A Not for Profit Organization may raise funds on an SSE through:
- Zero Coupon Zero Principal (ZCZP) Instruments
- Donations through Mutual Fund schemes as specified by SEBI
- Any other means SEBI specifies
The chapter also discusses Social Impact Funds, Development Impact Bonds and equity or debt of Section 8 companies.
ZCZP instruments
- Issued only by an NPO registered on an SSE (regulation 292I)
- No coupon, and no principal repaid on maturity
- Only for a specific project or activity in the 292E eligible list, completed within the duration in the fundraising document (292J)
- Tenure equals the project duration; at maturity it is written off the investee's books
- Notified as securities under the Securities Contracts (Regulation) Act, 1956 with effect from 15 July 2022
- Issued to the public (public issue) or to Social Impact Funds registered under the AIF Regulations, 2012 (private issue); public-issue rules apply mutatis mutandis to the private issue
How is it different from a bond? A bond promises money back. A ZCZP promises a social return. It can still be "defaulted" — if the impact is not delivered, the NPO loses the funder's trust and future donations.
Listing ends when either: (a) the object is achieved and a certificate is submitted to the SSE, or (b) the tenure has expired.
In May 2026, the Ministry of Corporate Affairs amended the CSR Rules to include the definitions of NPO and ZCZP in line with the ICDR Regulations, and introduced Rule 4A to enable CSR through ZCZP instruments.
Social Impact Funds (SIF)
A Social Impact Fund is an Alternative Investment Fund investing primarily in social ventures or social enterprises and meeting its own social performance norms. It issues social units to investors who agree to receive only social returns — no financial return.
- Cheaper for NPOs: lower issue expenses than ZCZPs
- Units can be listed, but trading potential is limited for 100% grant-in / grant-out funds
- An existing SIF may invest 25% of investable funds in securities of NPOs registered or listed on an SSE
- An SIF launched exclusively for registered or listed NPOs may invest 100%
Investable funds = the scheme's corpus net of estimated administration and management expenditure over the fund's tenure.
Pay-for-success structures
Here conventional capital (institutions, banks) joins social capital (foundations, CSR, impact investors). Conventional capital earns a return only if social impact is demonstrably created. Three types:
(a) Through Social / Development Impact Bonds — an intermediary aggregates NPOs working towards similar outcomes.
(b) Through lending partners — banks or NBFCs give a multi-year unsecured loan to a well-tested programme. Outcome funders agree to pay for pre-set outcomes. Part of their money sits in escrow to pay interest; principal is repaid only when outcomes are achieved. The intermediary may offer a first-loss default guarantee.
(c) Through grants — a company's CSR arm picks an NPO and puts CSR money in escrow for a set period (say, 3 years). The CSR funder appoints and pays for a third-party evaluator. A fourth entity, the interim funding partner (typically a domestic philanthropic organisation), funds the work up front.
| Result | What happens to the escrow money |
|---|---|
| Outcomes achieved | Paid to the interim funding partner to cover its cost |
| Outcomes exceeded | Also an accelerator grant up to 10% of programme cost to the NPO, for non-programme needs |
| Not achieved, period not over | Rolled over in escrow |
| Not achieved, period over | Routed to Schedule VII items such as the PM's Relief Fund |
| Interest earned in escrow | Stays in the account |
The workbook mentions Pratham and Godrej Properties Ltd. designing a loan-guarantee scheme for micro-entrepreneurs — a variation on grants-in, grants-out.
Development Impact Bonds (DIBs)
A DIB pays a grant to an NPO after it delivers pre-agreed social metrics at pre-agreed costs.
| Partner | Role |
|---|---|
| Outcome funder | Pays after results — CSR donors, foundations, retail investors, Government |
| Risk funder / investor | Puts in upfront capital and bears non-delivery risk; gets back investment with interest (approx. 4–8%) if targets are met, or loses part if not |
| Service provider / implementation agency | NPOs and/or FPEs doing the work |
| Independent third-party evaluator | Measures the social outcome |
| Intermediary / programme manager | Brings everyone together; can also be the Government |
If the Government is the outcome funder, the bond is called a Social Impact Bond (SIB). The workbook says India is yet to see such an example.
When DIBs fit: proven proof of concept; well-defined measurable metrics; relatively large projects; providers able to scale and handle extra monitoring. When they do not: no proven pilot; lots of innovation needed; too many variables; outcomes cannot be linked to the intervention; the solution is a product or tool rather than an intervention.
Facts to remember:
- Brookings (2020): 194 impact bonds across 33 countries; 177 in the UK and US; over USD 420 million deployed
- Quality Education DIB (India): USD 10 million, literacy and numeracy for two lakh children in Rajasthan, Gujarat and Delhi; providers KEF, Gyanshala, SARD
- UK pioneered the SIB; its Innovation Fund supported 10 SIBs
- USA calls them Pay For Success; SIPPRA passed in 2018
- Indian philanthropy market: over ₹35,000 crore
Routes for FPEs
All existing corporate fundraising routes stay open. A For Profit Enterprise may raise funds through:
- Equity shares on the main board, SME Platform or Innovators Growth Platform (IGP), or equity issued to an AIF including a Social Impact Fund
- Debt securities (listed on the main board)
- Other means SEBI specifies
Their securities trade in the applicable segment with an identifier saying the scrip is a For Profit Social Enterprise. They must meet that segment's eligibility rules plus social impact disclosures. The critical difference from a normal company: social impact reporting under the minimum reporting standard.
Beyond the book
The workbook's footnote traces the Governing Council requirement to a SEBI circular of October 2022, and ZCZP securities status to July 2022. Other footnotes cite SEBI circulars from 2024 and 2026. Treat the SSE as a young market whose rules are still being revised — always read the workbook version you are examined on.
Think of it like this
A ZCZP instrument is a temple renovation receipt
Your mohalla temple collects money to rebuild its roof by Diwali. You give ₹5,000 and get a receipt. You will never get the ₹5,000 back, and nobody pays you interest. What you "own" is a promise: the roof gets rebuilt.
If Diwali comes and the roof is still leaking, you do not sue — but you never give that committee money again. That is a ZCZP: zero coupon, zero principal, tenure equal to the project, and the only "default" is failing to deliver the social result, which costs the NPO its future funding.
A Development Impact Bond is a coaching class with a results guarantee
A coaching centre in Kota wants to teach 100 poor students but has no cash. A local businessman (the risk funder) pays the fees up front. A charitable trust (the outcome funder) promises: "If 60 of them clear the exam, we repay the businessman with a little extra." An independent examiner (the evaluator) checks the results. A retired principal (the intermediary) wrote the deal and brought everyone to the table.
If the students succeed, the businessman earns a small return. If not, he loses part of his money. The trust never pays for failure — which is exactly why outcome funders like DIBs.
The pay-for-success grant escrow is a wedding gold deposit
A family keeps gold with a trusted jeweller for a daughter's wedding "in three years". If the wedding happens, the gold is released. If it is postponed but the three years are not up, it stays locked. If the time runs out, the family gives it to a temple as promised.
The CSR escrow works the same way: outcomes achieved → money released (partly to the interim funder, with an accelerator grant up to 10% if targets are beaten); not achieved but time left → rolled over; time over → routed to Schedule VII items such as the PM's Relief Fund. Interest earned stays in the locker.
The starvation cycle is a tiffin service that can only buy food
Imagine donors who say: "Our money is only for rice and dal — not for the gas cylinder, the kitchen rent or the cook's training." The tiffin service feeds people today, but the stove breaks, the cook never improves and the kitchen cannot expand.
That is the starvation cycle. Institutional donations restricted to programmes leave NPOs to pay rent, utilities, training and research from internal resources — so they never build the capacity to grow.
