Municipal Bonds and Green Bonds for NRIs: A Niche, Developing Market, and Where It Actually Fits Your Fixed-Income Allocation

A municipal corporation in Tiruchirappalli raised Rs 100 crore in February 2026 at an 8.50% coupon for ten years. Vadodara issued at 7.9% in 2024. On paper those are some of the highest sovereign-adjacent yields available in rupees, well above what a G-sec or an NRE deposit pays. So a reasonable NRI question follows: can I lend money to an Indian city, or to the green-infrastructure programme of the Government of India, and pocket that yield? The honest answer splits cleanly in two. The municipal bond door is, for practical purposes, shut to you. The green bond door, specifically the Sovereign Green Bond, is genuinely open, and it opened wider on June 5, 2026.

This guide treats both honestly, including the parts the marketing pages skip. The Indian municipal bond market is small, illiquid, and built for institutions, not for a retail NRI in Dubai or Slough. The Sovereign Green Bond is a real, accessible, fully-repatriable instrument, but it is a G-sec wearing a green label, taxed like a G-sec, and it still loses to a tax-free NRE FD on after-tax income for most high-slab NRIs. Knowing which is which saves you from chasing a yield you cannot actually buy.

The 30-second answer: Indian municipal bonds are a niche, institutional market, roughly Rs 4,500 crore of cumulative issuance across about 31 issues by 22 cities by early 2026, almost all privately placed to banks, insurers and provident funds. NRIs cannot meaningfully buy them; the few listed issues have near-zero secondary liquidity. Sovereign Green Bonds (SGrBs) are the accessible option: the RBI made 10-year SGrBs Fully Accessible Route securities from November 2024, widened again on June 5, 2026, so NRIs and OCIs can hold them with no ceiling and full repatriation, either domestically (NRE or NRO funded) or via the GIFT City IFSC. Recent SGrB coupons run about 7.10% to 7.37%. Interest is taxable at slab with TDS up to 20% before DTAA relief; listed-bond gains are 12.5% over 12 months. After tax, a tax-free NRE FD at 6.50% to 7.55% still usually wins.

This guide assumes you already know what an NRE or NRO account is and how your residency is determined; if not, start with NRE, NRO and FCNR accounts explained and the RNOR residency rules. What follows is the part that decides whether any of this belongs in your portfolio: what these instruments actually are, who can buy them and how, the coupon and yield reality, the tax and TDS treatment, the liquidity and credit caveats that matter most, and an honest comparison against the boring NRE FD and the plain G-sec that most of this is really competing with.

What municipal bonds are, and why India barely has a market

A municipal bond is debt issued by an urban local body, a city or town municipal corporation, to fund local infrastructure: water supply, sewerage, roads, an airport link, an affordable-housing scheme. The city promises a fixed coupon, usually twice a year, and returns the principal at maturity. In the United States this is a vast, deep market with genuine retail participation, and the interest is famously tax-exempt at the federal level. India is nowhere close to that.

The Indian municipal bond market is small to the point of being a rounding error. Cumulative SEBI-regulated municipal bond issuance reached only about Rs 4,540 crore across roughly 31 issues by 22 cities by early 2026, with the bulk of activity concentrated in the past few years after SEBI introduced the SEBI (Issue and Listing of Municipal Debt Securities) Regulations in 2015. To put that in proportion, India's corporate bond market is measured in lakhs of crore, and a single large NBFC can raise more in a year than every Indian city has raised through bonds in a decade.

There are structural reasons the market is this thin. Most Indian municipalities have weak, opaque finances and limited revenue autonomy, which makes credit assessment hard and ratings expensive to obtain and maintain. Bond issuance also competes with cheap government grants and lending from agencies, so cities have had little incentive to take the harder, more disciplined bond route. The issues that do happen are usually privately placed, sold directly to a small set of institutional buyers, banks, insurers, provident funds, and large mutual funds, rather than offered to the public. That matters enormously for you, because a privately placed bond is not something a retail investor, resident or NRI, subscribes to.

A handful of municipal bonds are listed on the BSE or NSE debt segment after issue. In principle, a listed bond can change hands in the secondary market, and an NRI with a demat account could buy one there on a non-repatriation basis. In practice the secondary market for muni bonds is close to dormant. There is rarely a seller, the spreads are wide, and the volumes are negligible. You can want to buy a Tiruchirappalli or a Vadodara bond all you like; there is usually nothing on the screen to actually transact against.

Can an NRI buy Indian municipal bonds? The honest answer

For practical purposes, no. There are three layers to that no.

First, the primary market is almost entirely private placement to institutions, so there is no public retail tranche an NRI can apply to in the way you might apply to an IPO or a public NCD issue.

Second, where a bond is publicly issued and listed, the regulatory path for an NRI to hold it runs through the same corporate-bond and demat plumbing covered in NRI corporate bonds and NCDs: an NRE or NRO demat account, FEMA-compliant funding, and attention to whether the holding is repatriable. The rules permit it; the supply does not exist.

Third, even setting eligibility aside, the liquidity and credit caveats are disqualifying for most NRIs. You would be buying an illiquid, often sub-AAA instrument issued by a municipal body whose finances you cannot easily monitor from abroad, with no realistic exit before maturity. That is the opposite of what fixed income is supposed to do in a portfolio held from another time zone.

So my framing is blunt. Treat Indian municipal bonds as an institutional product that NRIs cannot meaningfully access yet. Watch the space, because SEBI has floated concept papers to deepen and standardise the market and more cities (Agra, Prayagraj, Varanasi among them) are in the issuance pipeline. But do not build a single line of your allocation around a muni bond today. There is almost certainly nothing for you to buy, and if there were, the liquidity would trap you.

Green bonds: the part that actually works for NRIs

Now the better news. A green bond is debt where the issuer commits to spending the proceeds on environmentally aligned projects, renewable energy, clean transport, water and waste management, and reports on that use. The green label does not change the credit risk; it changes only what the money is earmarked for. A green bond from a given issuer ranks alongside that issuer's ordinary debt.

India has two relevant green-bond layers. There is a corporate and PSU green-bond segment, where entities like power and renewable companies issue green-labelled NCDs; for an NRI these behave exactly like the instruments in NRI corporate bonds and NCDs, with the same eligibility, the same credit-rating caveats, and the same illiquidity risk. That segment is not the headline.

The headline is the Sovereign Green Bond (SGrB), issued by the Government of India through the RBI as part of its green-financing programme since FY2022-23. An SGrB is, in credit terms, identical to an ordinary dated G-sec: it carries the full faith of the sovereign, pays a fixed semi-annual coupon, and returns face value at maturity. The only difference is that the proceeds are ring-fenced for green projects under India's sovereign green-bond framework. For your purposes this is the cleanest, safest green exposure in rupees, and unlike municipal bonds, you can actually buy it.

How NRIs access Sovereign Green Bonds: the FAR route and the IFSC route

Two doors, and you should understand both.

The Fully Accessible Route (domestic holding). The FAR is the RBI framework, live since April 1, 2020, that designates a specific list of government securities as open to non-residents with no quantitative ceiling and full repatriation of capital and returns. The RBI brought 10-year SGrBs into FAR from November 2024, and on June 5, 2026 widened the FAR list further to cover new long-tenor issuances and Sovereign Green Bonds explicitly. The effect for you is that a FAR-designated SGrB sits in the same uncapped, repatriable bucket as ordinary FAR G-secs. You can hold it domestically through an NRE or NRO account and either a Retail Direct Gilt account or an NRI demat account, exactly as described in NRI government bonds and RBI Retail Direct. Fund from NRE for genuinely uncapped, fully repatriable holding; fund from NRO and you fall back to the USD 1 million per financial year NRO repatriation limit with Forms 15CA and 15CB.

The IFSC route (GIFT City, foreign-currency holding). Since 2024 the RBI has allowed NRIs to invest in SGrBs through the GIFT City International Financial Services Centre. Here you open a foreign-currency account with an IFSC banking unit (ICICI, HDFC, SBI, Kotak and others run IFSC units), complete KYC online with your passport and overseas address proof, and transfer money in by SWIFT from your overseas bank. This route is particularly relevant for US and Canada NRIs, who face the heaviest friction on the domestic side because of FATCA, PFIC and account-opening restrictions; the IFSC route lets them hold the bonds in a foreign-currency wrapper without routing through a domestic NRO setup. For the broader mechanics and the tax nuances of investing through this centre, read GIFT City investing for NRIs and the GIFT City IFSC route for US and Canada NRIs.

One caveat on the IFSC route worth flagging now, because the marketing pages oversell it: SGrBs are not currently covered by the Section 47(viiab) capital-gains exemption that applies to some other IFSC-traded securities. So buying or selling an SGrB through GIFT City does not make your capital gain automatically tax-free in India the way some genuinely IFSC-exempt instruments are. Hold that thought for the tax section.

Coupons and yields: what the numbers actually look like

Strip away the labels and you are buying sovereign rupee debt, so the yield sits in the G-sec band, not above it.

Recent 10-year Sovereign Green Bonds have carried coupons in the region of 7.10% to 7.37%, with the latest 10-year SGrB around 7.29%. That is broadly in line with, and sometimes a touch below, the equivalent-tenor ordinary G-sec, because at times strong demand for the green label has produced a small "greenium," a slightly lower yield the issuer enjoys for the green branding. As an investor, a greenium is a cost to you, not a benefit: it means you accept marginally less yield for the same sovereign credit. In practice the gap has been small and inconsistent, so treat an SGrB as paying roughly the same as a same-tenor G-sec, near 7%.

Municipal bonds, by contrast, do carry a genuine yield premium, roughly 7% to 8.5%, with recent issues like Tiruchirappalli at 8.50% and Vadodara at 7.9%, often 75 to 100 basis points above a comparable AAA corporate bond. But that premium is the market pricing in weaker credit and near-total illiquidity, and as established above, you cannot reliably buy these anyway. A yield you cannot access is not a yield.

So the realistic NRI choice on the bond side of a fixed-income allocation is: an SGrB or ordinary G-sec near 7%, fully repatriable through FAR, versus an NRE FD paying 6.50% to 7.55% tax-free. That is the comparison that matters, and the next two sections settle it.

Taxation of interest and capital gains for NRIs

This is where the green label disappears entirely. An SGrB is taxed exactly like an ordinary G-sec. There is no special tax break for individual NRIs holding green bonds; the green framework governs the issuer's spending, not your tax.

Interest (coupon). SGrB and G-sec coupon interest is taxable in India at your slab rate as income from other sources. For most working NRIs earning well abroad, the relevant Indian rate, on the India-source bond interest alone, lands in the higher slabs. This is the single biggest difference from the NRE FD, whose interest is fully exempt from Indian tax under Section 10(4)(ii).

Municipal bond interest is taxable at slab in the same way, with one exception: interest from a specifically notified tax-free municipal bond is exempt under Section 10(15). Only a small subset of past municipal issues carried that notified status, so do not assume any given muni bond is tax-free; check the specific ISIN.

Capital gains (if you sell before maturity). For listed bonds, including listed SGrBs and listed municipal bonds, held for more than 12 months, long-term capital gains are taxed at 12.5% without indexation for transfers on or after July 23, 2024. Held 12 months or less, the gain is short-term and taxed at your slab rate. Note the trap for unlisted bonds: under Section 50AA, unlisted bonds transferred, matured or redeemed on or after July 23, 2024 are always treated as short-term and taxed at slab, regardless of holding period. If you hold to maturity and simply collect face value, there is generally no capital gain at all; the only taxable stream is the coupon.

The IFSC nuance. Because SGrBs do not qualify for the Section 47(viiab) exemption, a gain on selling an SGrB through the GIFT City IFSC is not automatically exempt. It is treated broadly as it would be on the domestic exchange. Do not buy the "tax-free GIFT City" framing without checking it against the specific security; for SGrBs it does not hold on the capital-gains side.

DTAA relief and foreign tax credit. Whatever India taxes, you can usually mitigate double taxation. India-source bond interest taxed in India is generally creditable against the tax your country of residence levies on the same income, under the relevant Double Taxation Avoidance Agreement. The mechanics, the Tax Residency Certificate, Form 10F, and the foreign tax credit, are covered in DTAA relief for NRIs and the foreign tax credit and Form 67. For UAE-resident NRIs in particular, where there is no personal income tax at home, the India-side tax is effectively the whole bill; see the UAE zero-CGT and DTAA position.

TDS: what gets withheld before the money reaches you

Tax does not wait for your return; it is withheld at source. For non-residents, bond interest is commonly subject to TDS of up to 20% (plus applicable surcharge and cess) before any treaty relief. This is materially higher than the TDS on many resident bond holdings, and it is deducted whether or not your final liability is that high.

Two levers reduce it. First, DTAA relief: by filing a valid Tax Residency Certificate and Form 10F, you can have TDS applied at the lower treaty rate where the treaty caps interest withholding below 20%. Second, where even the treaty rate over-withholds relative to your actual liability, a lower or nil TDS certificate under Section 197 (Form 13) can bring the deduction down; the process is covered in the lower TDS certificate, Form 13. Either way, if TDS exceeds your final tax, you reclaim the excess by filing your ITR for AY 2026-27. For the broader picture on withholding and refunds, see TDS for NRIs and refunds.

Contrast this with the NRE FD again: zero TDS, zero filing obligation on the interest, because the interest is exempt. The administrative simplicity of the NRE FD is itself a real, if unglamorous, advantage.

Worked example: SGrB versus NRE FD on Rs 20 lakh

Take a UK-resident NRI with Rs 20,00,000 to place in rupee fixed income for ten years, comparing a 10-year Sovereign Green Bond at a 7.29% coupon against a 10-year NRE FD at 7.00% tax-free. Assume the NRI's India-source income pushes the bond interest into the 30% slab, plus 4% cess, an effective 31.2% on the coupon.

Sovereign Green Bond, Rs 20,00,000 at 7.29%:

• Gross annual coupon: Rs 20,00,000 x 7.29% = Rs 1,45,800
• Indian tax at 31.2% on the coupon: Rs 1,45,800 x 31.2% = Rs 45,489
• Post-tax annual income: Rs 1,45,800 minus Rs 45,489 = Rs 1,00,311
• TDS withheld up front: up to 20%, so up to Rs 29,160 a year deducted before the money reaches you, with the balance of tax settled (and any DTAA credit claimed) at filing.

NRE FD, Rs 20,00,000 at 7.00%, tax-free:

• Gross annual interest: Rs 20,00,000 x 7.00% = Rs 1,40,000
• Indian tax: nil (exempt under Section 10(4)(ii))
• TDS: nil
• Post-tax annual income: Rs 1,40,000

The bond pays a higher headline coupon, 7.29% against 7.00%, and still loses by Rs 39,689 a year after tax, Rs 1,40,000 against Rs 1,00,311, purely because the FD interest escapes Indian tax and the bond interest does not. Over ten years, ignoring reinvestment, that is roughly Rs 3,96,890 more in your pocket from the deposit. For a high-slab NRI, the tax-free NRE FD wins decisively on after-tax income, before you even count the bond's TDS friction and reclaim paperwork.

The bond only starts to catch up if your effective Indian rate on the coupon is low (you are in a lower slab, or your home-country credit washes out the India tax in a no-tax jurisdiction like the UAE), or if you value what the bond offers that the FD cannot: a 10-year locked yield that no bank deposit matches in tenor, tradability at market price before maturity (liquid for SGrBs, effectively not for muni bonds), and a direct sovereign claim with no bank to fail and no Rs 5 lakh deposit-insurance ceiling. Those are real, but they are duration and structure benefits, not income benefits.

Where these fit (and do not yet fit) an NRI fixed-income allocation

Put the pieces in order of usefulness.

Municipal bonds: not yet. No reliable access, weak and opaque credit, near-zero liquidity. Zero allocation for almost every NRI, regardless of the tempting 8%-plus coupons. Revisit only if SEBI's market-deepening efforts produce genuine retail, listed, liquid issues.

Sovereign Green Bonds: a satellite, not a core. They are a perfectly sound, fully-repatriable way to hold long-duration rupee sovereign debt, and the FAR and IFSC routes make them genuinely accessible. But because they are taxed like a G-sec and the NRE FD is tax-free, an SGrB is rarely the most tax-efficient income holding for a high-slab NRI. Its real role is as a duration anchor: if you specifically want to lock a sub-7.5% yield for ten years in your own name, with tradability and a direct sovereign claim, an SGrB does that and a 5-year FD does not. If your motivation is the green mandate itself, that is a values choice, and a legitimate one, just go in knowing you are accepting the same yield as a plain G-sec for it.

The default for most NRIs remains the NRE FD for money you want safe, simple, tax-free and repatriable, and the plain FAR G-sec or a target-maturity product for duration. Compare those directly in NRE FD vs FCNR FD, the Bharat Bond ETF and target-maturity funds, and where to park as an NRI. For how the whole fixed-income sleeve sits inside a portfolio, see NRI portfolio asset allocation.

Edge cases

RNOR returnees. If you are in the Resident but Not Ordinarily Resident window after returning, your global income is not yet fully taxable in India, but India-source SGrB and muni bond interest is taxable regardless, and your NRE FD interest exemption ends once you become a resident. The trade-off between bonds and deposits shifts the moment you return; see the RNOR window and NRE vs resident savings after return.

US NRIs and the PFIC question. Holding an individual SGrB or muni bond directly is not a PFIC problem, because a single bond is not a pooled fund. But if you reach for green exposure through an Indian green-bond mutual fund or ETF, you walk straight into the PFIC trap that makes Indian funds punitive for US persons; read the US NRI PFIC trap before you buy any fund wrapper. The IFSC route for individual SGrBs is the cleaner US-NRI path.

The "greenium" working against you. When green demand is strong, an SGrB can yield slightly less than the equivalent G-sec. If maximising yield is the only goal, buy the plain G-sec; the green bond is for investors who value the mandate or simply want sovereign duration and find an SGrB on offer at the same yield.

Notified tax-free municipal bonds in the secondary market. A few old municipal or infrastructure issues carry Section 10(15) tax-free interest. If you ever do find one available, the exempt coupon changes the after-tax maths in the bond's favour, but the illiquidity and the difficulty of verifying notified status from abroad usually still rule it out. Verify the ISIN's tax status before assuming anything.

Currency, not just tax. Every rupee instrument here carries rupee depreciation risk against your home currency. A 7% rupee coupon is not a 7% return in pounds or dollars once the rupee slips. That applies equally to the NRE FD, but it is worth holding in view; see NRI real returns after rupee depreciation.

The closing read

For municipal bonds, the honest read is short: this is a real but tiny, institutional, illiquid market that an NRI cannot meaningfully participate in today, and the eye-catching 8%-plus coupons are eye-catching precisely because the credit is weaker and the exit is non-existent. Skip it. Watch SEBI's market-deepening work, and revisit only if listed, liquid, retail-accessible municipal issues actually arrive.

For green bonds, the honest read is more nuanced. Sovereign Green Bonds are genuinely accessible to NRIs, through FAR domestically and through the GIFT City IFSC for those who want a foreign-currency wrapper, with no ceiling and full repatriation when funded from NRE. They are as safe as any G-sec because they are a G-sec with a green label. But they are taxed like a G-sec too, and on after-tax income a high-slab NRI almost always nets more from a tax-free NRE FD paying 6.50% to 7.55% than from a green bond yielding around 7.29%. So the SGrB earns a place only as a long-duration anchor or a deliberate values allocation, not as your default income holding. If the goal is simple, safe, tax-free rupee income, the boring NRE FD still wins. If the goal is a decade-long locked sovereign yield in your own name, or backing India's green programme with eyes open about the yield you give up, the Sovereign Green Bond is a sound, if unspectacular, place to put a slice of the fixed-income sleeve.
