India's green bonds find footing as stable 'greenium' underscores investor appetite
India sold Rs 50 billion (₹5,000 crore, about $524 million) of 30-year sovereign green bonds
The sale priced at a "greenium" of four basis points below comparable conventional government securities
This took the average greenium for the fiscal half-year to four basis points, the highest half-yearly average since sovereign green bond sales began in the second half of FY2023
The sustained greenium is being read as a sign of steady investor appetite for India's green debt instruments
Sovereign Green Bonds (SGrBs) and India's Framework
Sovereign Green Bonds are government-issued debt instruments where proceeds are earmarked exclusively for projects with environmental/climate benefits, distinguishing them from conventional government securities (G-Secs) whose proceeds fund general government expenditure.
Key Details
- India's Sovereign Green Bond Framework was released by the Department of Economic Affairs on 9 November 2022, based on the International Capital Market Association's (ICMA) Green Bond Principles
- India's debut SGrB issuance was in January-February 2023 (Rs 16,000 crore in two tranches), issued via the RBI as the government's debt manager, using the same auction mechanism as regular G-Secs
- Eligible categories include renewable energy, clean transportation, energy efficiency, sustainable water and waste management, and climate change adaptation
- Explicit exclusions under the framework: fossil fuel extraction/production projects, nuclear power generation, hydropower plants larger than 25 MW, and direct waste incineration
- India has issued SGrBs multiple times since FY2023, cumulatively raising tens of thousands of crores of rupees
The Rs 50 billion 30-year green bond sale is part of this ongoing SGrB issuance program under the 2022 Framework, and the long (30-year) tenor signals investor willingness to hold India's green debt for the long term.
"Greenium" — The Green Premium Concept
A "greenium" is the yield discount (equivalently, price premium) that green bonds command over otherwise identical conventional bonds, reflecting investors' willingness to accept a slightly lower return in exchange for environmental/ESG-labelled exposure.
Key Details
- A positive greenium means the government borrows more cheaply via green bonds than via regular G-Secs of the same tenure — i.e., the green label itself reduces the cost of capital
- India's SGrB greenium has generally been in the low single digits of basis points (commonly cited range: 2-6 basis points), below the global average greenium of roughly 7-8 basis points cited for developed-market green bonds
- The greenium is driven by demand from dedicated ESG/green-mandate investors (domestic and international) who have limited pools of eligible green paper to invest in relative to demand
- A stable or rising greenium across issuances signals maturing investor demand, as opposed to fading interest reflected in a shrinking or disappearing greenium
A four basis point greenium sustained over a fiscal half-year, the highest half-yearly average on record for this program, indicates deepening and more consistent investor demand for India's green bonds rather than a one-off pricing effect.
Green Bonds and India's Climate Finance Commitments
Sovereign green bond proceeds are one channel through which India mobilises the large capital pool required to meet its climate and energy transition targets under its Nationally Determined Contributions (NDCs).
Key Details
- India's updated NDC (2022) targets a 45% reduction in emissions intensity of GDP by 2030 (from 2005 levels) and achieving about 50% cumulative installed electric power capacity from non-fossil-fuel sources by 2030
- India has also committed to a "Panchamrit" target of net-zero emissions by 2070, announced at COP26 (2021)
- Green bond proceeds are typically allocated to public-sector renewable energy, clean transport, and afforestation-linked projects that directly contribute toward these NDC and net-zero pathways
- India's SGrB framework requires proceeds to be tracked and reported for use-of-proceeds and environmental-impact disclosure, in line with international green bond reporting norms
Sustained investor demand for India's green bonds (evidenced by the stable greenium) supports the government's ability to raise dedicated, potentially cheaper, long-term financing for the renewable energy and clean infrastructure buildout needed to meet its 2030 NDC and 2070 net-zero targets.
