The next phase of sustainable finance will not be won by better slogans. It will be won by better capital architecture. That is why the convergence between Maqasid al-Shariah and ESG matters. Properly understood, this is not a branding exercise that tries to make Islamic finance look modern by borrowing ESG language. It is a deeper proposition: that a financial system built around preservation of life, wealth, dignity, intellect, justice, and social balance is naturally positioned to finance the real economy challenges embedded in the 2030 Agenda. In 2025 and 2026, that argument is becoming harder to dismiss because the numbers have become too large, the development gaps too visible, and the financing tools too credible to ignore.

Start with the scale of the problem. UNCTAD said in 2025 that developing countries face an annual US$4.3 trillion financing gap to achieve the Sustainable Development Goals, including US$1.8 trillion for climate action. It also noted that 3.3 billion people live in countries that spend more on debt interest than on education or health. In its 2025 SDG Pulse, UNCTAD added that developing countries’ external debt reached US$11.7 trillion in 2024, while official development assistance fell 7.1%, the first decline in five years. That is the real backdrop for this debate. The question is no longer whether ethical capital sounds attractive. The question is whether the world can afford not to mobilize every credible pool of principled capital that can fund resilience, inclusion, adaptation, infrastructure, and social protection.

Now consider the scale of Islamic finance itself. LSEG’s Islamic Finance Development Report 2025 said global Islamic finance assets reached US$5.98 trillion in 2024, up 21% year on year. LSEG also noted in January 2026 that Islamic finance now has a footprint in 140 countries and could approach the US$10 trillion mark by the end of the decade. The IFSB’s 2025 Stability Report, using its own narrower industry perimeter, put the Islamic Financial Services Industry at US$3.88 trillion in 2024, with 71.6% in Islamic banking and 23.3% in sukuk outstanding; notably, sukuk grew 25.6% year on year. Even more relevant for this discussion, the ICD-LSEG report said the ESG sukuk market surpassed US$50 billion in outstanding value by the end of 2024, with global issuance up 14.7%. That is not a niche anymore. It is a capital market with enough scale to matter, but still enough white space to expand meaningfully.

This is where the Maqasid lens sharpens the ESG debate. ESG, at its best, asks whether capital is aligned with environmental stewardship, social responsibility, and governance quality. Maqasid asks whether economic activity protects essential human and societal interests. The overlap is obvious, but the distinction is important. ESG often begins with risk, disclosure, and screening. Maqasid begins with moral purpose and real-economy impact. One is often managerial. The other is civilizational. When combined well, they create something stronger than either on its own: a framework for allocating capital that is ethically grounded, operationally measurable, and development-oriented.

That is why one line from Majid Dawood, founder and CEO of Yasaar, deserves attention: “Islamic finance is about financing real growth with real money.” That is more than a theological statement. It is a direct challenge to the excesses of speculative, extractive, or socially detached finance. It also happens to fit the 2030 Agenda rather well. The SDGs do not need more abstract capital. They need capital tied to assets, livelihoods, public goods, and long-duration development outcomes.

Three developments make this nexus especially relevant now.

• First, the market is maturing from exclusion to impact. For years, Islamic finance proved its ethical credentials mainly through negative screens and leverage discipline. That remains important, but it is no longer enough. Investors increasingly want to know where proceeds go, what outcomes are financed, and how impact is measured.

• Second, sustainable sukuk is becoming a practical bridge. It allows Islamic capital to fund renewable energy, clean transport, affordable housing, education, adaptation, food systems, and SME ecosystems without breaking faith with Shariah principles.

• Third, regulators and issuers are building the plumbing. Taxonomies, sustainable finance frameworks, second-party opinions, external verification, and use-of-proceeds reporting are making the Maqasid-ESG convergence more investable.

The strongest proof, however, comes from real-world cases.

Indonesia remains the benchmark case for sovereign leadership. The World Bank’s 2025 country progress report notes that Indonesia issued the world’s first sovereign green sukuk in 2018 and has continued multiple sovereign global green sukuk issuances since then. UNDP and OJK reported in late 2025 that, since 2018, Indonesia has issued more than US$12.6 billion in thematic bonds and sukuk, including green sukuk, SDG bonds, and blue bonds. The same report says that by June 2025, cumulative corporate thematic bond issuance had reached about IDR 65.77 trillion, or roughly US$4.11 billion, while cumulative thematic issuance across domestic and international markets reached about US$16.5 billion by 2024. This is what the nexus looks like in practice: Shariah-compatible capital financing climate, oceans, and development priorities through a credible sovereign framework.

The Islamic Development Bank offers the multilateral version of the story. At the Global Sukuk Summit in October 2025, Dr. Muhammad Al Jasser, Chairman of the IsDB Group, said: “Sukuk represents capital with purpose, channeling financing into infrastructure, renewable energy, healthcare, and education.” That statement is backed by market action. IsDB said it has mobilized over US$55 billion in sukuk since 2003 through nearly 80 issuances, including almost US$6 billion in Green and Sustainability Sukuk. In October 2025 alone, it issued a €500 million Green Sukuk under an enhanced sustainable finance framework that added climate adaptation and food security as eligible categories. This is not just capital raising. It is institutional proof that Islamic finance can be structured around measurable development outcomes while staying close to its asset-linked logic.

Dubai Islamic Bank shows how this convergence is moving into mainstream banking practice. In its 2025 semi-annual sustainable finance report, DIB said it had issued US$2.75 billion in sustainable sukuk across three transactions, with proceeds allocated against an eligible sustainable asset portfolio of US$2.45 billion. It reported 109,107 tonnes of CO2e avoided and noted full allocation of all three issuances by September 2025. DIB’s prospectus also states that its first US$750 million sustainable sukuk in 2022 was the first by a UAE bank and the largest sustainable sukuk issue in the GCC at the time. This matters because it shows Islamic banks can move beyond generic ethical positioning into auditable, reportable, outcome-linked finance.

So what should happen next? Three priorities stand out.

• Move from Shariah compliance to Maqasid performance. The market needs instruments that do not merely avoid prohibited sectors but actively demonstrate contribution to resilience, livelihoods, equity, and ecological stewardship.

• Build better measurement. If ESG brought metrics discipline to global finance, the next step is to map those metrics more deliberately to Maqasid outcomes. Investors should be able to see not just use of proceeds, but use of purpose.

• Scale blended and catalytic structures. The SDG gap will not be closed by public finance alone. Islamic finance can work much harder through blended finance, guarantees, waqf-linked innovation, social sukuk, adaptation finance, and SME transition vehicles.

The strategic point is straightforward. The Maqasid Shariah-ESG nexus is not about forcing two vocabularies together. It is about recognizing that one of the world’s fastest-growing ethical financial systems may be unusually well suited to an era defined by debt stress, climate risk, inequality, and mistrust of finance detached from social purpose. If the first era of Islamic finance was about proving legitimacy, the next era may be about proving utility. And for the 2030 Agenda, that shift could not be more timely.
