Indonesia Sold the World's First Sovereign Green Sukuk. Here's What Actually Makes a Sukuk 'Green'

In March 2018, the Indonesian government sold a $1.25 billion, 5-year sukuk in New York and London, priced at a 3.75% yield. It was not the first sukuk Indonesia had ever issued. It was the first sovereign green sukuk any country had ever issued, anywhere (sukuk.com; Green Finance Platform). If you have ever seen "Green Sukuk" printed on a retail SBN offering and wondered what the word "green" is actually doing there, since the risk and the government guarantee look identical to a regular sukuk, here is what changes and what does not.
A regular sukuk, as explained in our piece on how sukuk differs from a conventional SBN, is structured around leasing a government-owned asset instead of paying interest. A green sukuk uses that exact same legal structure. The only thing added is a rule about where the money raised is allowed to go.
The proceeds must fund projects in one of five categories: renewable energy, sustainable transport, waste management, climate-resilient infrastructure for disaster-prone areas, or sustainable agriculture. Every year, ministries flag budget line items that qualify under a process called Climate Budget Tagging, and only tagged projects inside that year's state budget (APBN) can be funded with green sukuk money (Bareksa). Your risk as a bondholder does not change. You are still lending to the same government, under the same guarantee. What changes is a legal commitment on the spending side.
The 2018 debut was just the start. In June 2021, Indonesia sold a $3 billion, three-tranche global sukuk, and its 30-year, $750 million tranche was the first 30-year green sukuk any issuer, sovereign or corporate, had ever priced. That sale drew $10.3 billion in orders, more than three times what was on offer (DDCAP; Bank Indonesia).
By its fifth global green sukuk issuance in 2022, Indonesia had raised a cumulative $6.9 billion in USD proceeds alone, on top of separate rupiah-denominated retail and wholesale green sukuk sold domestically. Sustainable transport has taken the largest single share of that money, about 32%, followed by food security and climate resilience projects at around 28% (Databoks/Katadata).
You do not need to be a global institutional investor to hold one. Indonesia's Sukuk Tabungan (ST) retail series occasionally includes a green-labeled tranche, sold alongside a regular tranche of the same series. ST016, offered 8 May to 3 June 2026, is the most recent example:
| ST016T2 (regular) | ST016T4 (Green Sukuk) | |
|---|---|---|
| Tenor | 2 years | 4 years |
| Minimum coupon | 6.05% (BI rate + 130 bps) | 6.25% (BI rate + 150 bps) |
| Maximum purchase | Rp 5 billion | Rp 10 billion |
| Matures | 10 June 2028 | 10 May 2030 |
Both were sold with a Rp 1 million minimum ticket and a floating-with-floor coupon, meaning it can rise with the BI rate but never falls below the stated minimum (Kompas; Bareksa).
This is the part a regular sukuk does not have. Indonesia's Ministry of Finance publishes an annual Green Sukuk Allocation and Impact Report, prepared with the UNDP, disclosing exactly which tagged projects received funding and what they delivered. The use of proceeds is also audited by BPK, Indonesia's state audit body (UK Islamic Finance Council; Bareksa).
Past reports have named specific projects funded this way, including the Manggarai electric commuter rail hub in Jakarta, the Palembang light rail line, a waste management facility in Piyungan, Yogyakarta, and a solar panel installation in the Selayar Islands, South Sulawesi. That paper trail, tying an individual bond series to a named, auditable project, is the actual product being sold. The yield is not the pitch.
Every ST or SR series prices its coupon off the current BI rate, so where that rate sits when a new green sukuk series opens changes what you're locking in. Before the next offering window, check the current BI rate and Indonesia's government bond yield on NetWort's Macro Context page to see where rates stand.
