The Thesis
The outstanding value of ESG sukuk surpassed $61 billion for the first time at end-June 2026 — up 24% year-on-year. That is the good news. The less comfortable number: total ESG sukuk issuance in the first half of 2026 fell 32% year-on-year, to just $4.9 billion. A market that grows in outstanding stock while shrinking in new issuance tells a specific story. And it is fundamentally a Malaysian one.
What the Fitch Data Shows
Fitch Ratings published its H1 2026 analysis on July 22. The numbers are precise about where the market’s energy sits.
Malaysian issuers accounted for 67% of all ESG sukuk issuance in H1 2026, with every deal priced in Malaysian ringgit. That is nearly three times their H1 2025 volume. The sectors driving it: energy, utilities, and transportation — the infrastructure of the energy transition. In the Malaysian ringgit market, ESG sukuk issuance did not just hold. It surged.
The foreign-currency side is a different story. Foreign-currency ESG sukuk issuance fell sharply as the Iran war created geopolitical risk premiums that made international investors cautious. The deals that did not happen were largely the dollar and euro-denominated transactions that attract global institutional capital.
Looking at the outstanding stock by country: Malaysia holds 31% of total ESG sukuk outstanding, Saudi Arabia 27%, the UAE 20.2%, and Indonesia 15.3%. Four markets hold essentially the entire global ESG sukuk portfolio.
Why Malaysia Dominated
Three structural factors explain Malaysia’s surge.
First, tax incentives. Malaysia provides specific tax exemptions for Sustainable and Responsible Investment (SRI) sukuk under its income tax framework. That creates a pricing advantage for issuers that other markets have not yet matched.
Second, a deep domestic investor base. Malaysian pension funds, insurers, and unit trusts have been progressively mandated to hold increasing shares of SRI-labelled instruments. The demand is structural, not cyclical.
Third, local currency insulation. When geopolitical volatility hits foreign-currency markets, ringgit sukuk markets keep functioning. H1 2026 demonstrates exactly that dynamic: the global market contracted while Malaysia expanded, because Malaysian issuers and investors operate in a protected currency environment.
The Honest Caveat
The $61 billion outstanding figure looks strong. But there is something worth naming: the 24% growth in outstanding comes partly from past issuances still on balance sheets — it is not purely new activity. And new issuance fell 32%. If Malaysian ringgit activity slows — or if the domestic mandate reaches its limit — the headline outstanding figure does not automatically continue growing.
The foreign-currency contraction is also a real limitation for ESG sukuk’s global ambitions. A market that is 67% Malaysian ringgit is not yet a truly global market; it is a regional one with strong domestic drivers. For ESG sukuk to reach the institutional audiences that green bonds have reached in conventional markets, the dollar and euro segments need to recover.
What to Watch
Fitch expects Malaysia to lead global ESG sukuk supply in H2 2026 as well — supported by the same tax incentives, domestic demand, and market depth. That is the base case. But the more important variable is whether geopolitical conditions ease enough for foreign-currency issuance to return.
If the Middle East conflict de-escalates, foreign-currency ESG sukuk can resume. When it does, the question becomes whether Saudi Arabia and the UAE — 47% of total outstanding combined — bring new supply to defend their share, or whether Malaysia’s ringgit momentum continues to outpace them.
Either outcome is instructive. The global ESG sukuk market is not stagnating. It is reorganizing — and for now, it has a clear address.
