National Highways Authority of India (NHAI) InvITs and the National Highways Infra Trust (NHIT) offer investors an opportunity to participate in income-generating highway infrastructure assets without owning them directly. As infrastructure investment products, they differ from conventional corporate bonds in their structure, cash flow, and risk profile. Understanding how NHAI InvITs and NHIT work can help investors evaluate whether they are suitable for their investment objectives and overall portfolio.
NHAI vs NHIT explained
NHAI, the National Highways Authority of India, is the government body that builds and operates the country's highway network. NHIT, or National Highways Infra Trust, is a separate entity, an Infrastructure Investment Trust (InvIT) that NHAI sponsors to monetise already-operational road assets. Put simply, NHAI builds the roads; NHIT holds a portfolio of completed toll roads and passes on the cash they generate to investors.
How the InvIT structure works
An InvIT pools investor money to buy income-generating infrastructure assets, then distributes the resulting cash flows. NHIT holds its road assets through special purpose vehicles (SPVs) under 20 to 30-year concessions. Investors can invest either in InvIT units (similar to shares) or through listed non-convertible debentures (NCDs) issued by the trust. Each carries a different risk-return profile, so it's worth noting the two aren't interchangeable.
Underlying road assets
By the close of FY26, NHIT's portfolio had expanded following its fifth acquisition round, adding roughly 310 km of highway. This growth reflects NHAI's ongoing strategy of transferring completed toll roads to InvIT structures to raise capital for new construction. From an investor's perspective, a larger, more diversified asset base can reduce dependence on any single toll stretch, though it doesn't eliminate traffic-linked variability.
How Do NHIT Investments Generate Returns?
NHIT investments can generate returns through periodic income and potential capital appreciation, depending on the type of security held and prevailing market conditions.
Yield and distributions
Annualised distribution yield measures the yearly income an investment generates, expressed as a percentage of its current price or net asset value (NAV). NHIT reported an annualised distribution yield of approximately 8.5% for FY26, based on its per-unit distribution of ₹11.33 as of March 31, 2026. This is driven by toll collections and annuity payments from its underlying road assets. As a result, unit or bond holders receive periodic interest payments, though the yield figure is indicative and can move with toll traffic, interest rates, and asset valuations. Figures are approximate and subject to change based on market conditions.
Interest income
For NHIT's NCDs specifically, investors earn a fixed or floating coupon, the periodic interest paid on the face value (or par value) of the bond, rather than a variable unit distribution. This reflects the debt structure of NCDs, which sit senior to InvIT units in the repayment order. Coupon income on NCDs tends to be more predictable in structure than unit distributions, though both remain subject to the issuer's underlying cash flows.
Capital appreciation potential
NHIT units are listed and can trade above or below their issue price depending on demand, interest rate movements, and portfolio performance. Trading data shows NHIT units touched an all-time high near ₹160 in May 2026, according to TradingView. This reflects broader investor appetite for infrastructure yield instruments in a falling interest-rate environment. As a result, unit holders may see mark-to-market gains, though price movements can go either way and are not assured.
Why Do Investors Consider NHIT Investments?
Investors may consider NHIT for its exposure to operational infrastructure assets, potential regular income, and relatively strong credit profile, depending on their investment objectives and risk appetite.
Infrastructure exposure
NHIT offers indirect access to a diversified national highway portfolio without requiring investors to fund construction risk directly, since assets are typically operational before being absorbed into the trust.
Regular income potential
Distributions are typically paid quarterly, driven by contracted toll or annuity cash flows. This may suit to investors seeking periodic income streams as part of a broader portfolio, subject to underlying asset performance.
Credit quality considerations
Ind-Ra has assigned NHIT's NCDs a long-term rating of IND AAA with a Stable outlook, as per its rating rationale dated 2026, citing a diversified portfolio and consolidated debt service coverage ratio above 1.80x. A high credit rating is historically associated with lower default risk, though it does not represent a guarantee of repayment.
Taxation of NHIT Investments: What Investors Need to Know
Distributions from InvIT units can comprise interest, dividend, and capital repayment components, each taxed differently under Indian tax law. NCD interest income is typically taxed at the investor's applicable slab rate, with TDS provisions that may apply. Capital gains on unit or bond sales depend on the holding period and instrument type. Tax treatment depends on individual circumstances. Consult a qualified tax professional.
Risks of Investing in NHIT
Every income opportunity here carries a corresponding risk. Interest rate risk means rising rates can pressure InvIT unit prices, since yield instruments often move inversely to prevailing rates. Traffic and revenue risk reflects the fact that toll income depends on vehicle volumes, which can be affected by economic slowdowns or alternative routes. Regulatory risk includes changes to toll policy or concession terms set by government authorities. Market liquidity risk means that, while NHIT units and NCDs are listed on NSE and BSE, trading volumes in the secondary market may be thinner than for large-cap equities, which can affect exit pricing. Ind-Ra's rating note also flags pending arbitration matters and a stamp duty dispute in Karnataka as monitorable factors.
What Should Investors Check Before Investing?
Before considering NHIT-linked securities, some investors choose to review the credit rating assigned by agencies such as CRISIL, ICRA, or India Ratings, alongside the specific rating rationale. Yield expectations should be weighed against duration and prevailing interest rate conditions rather than viewed in isolation. Investment horizon matters too, since InvIT structures are designed around long-dated concessions. Finally, risk appetite should guide the choice between NCDs (debt) and units (equity-like), given their differing risk-return profiles.
How to Invest in NHIT-Linked Securities
Retail investors can typically access NHIT units through a Demat account via NSE or BSE, in the same way as listed equities. NCDs, when publicly issued, can be applied for through registered intermediaries or platforms during the issue window, and are later available on the secondary market. Eligibility broadly mirrors standard equity and bond market norms. Key documents to review include the offer document, rating rationale, and latest distribution and valuation reports published by NHIT.
Conclusion
NHIT offers first-time investors a way to gain exposure to India's highway infrastructure through listed units or NCDs, backed by operational toll assets and a AAA rating from India Ratings. That said, yield, price, and distributions are all linked to traffic patterns, interest rates, and regulatory conditions, making this an investment associated with market and credit risk rather than one with assured outcomes.
FAQs About NHAI InvIT Bonds
Are NHIT units and NHAI bonds the same?
No. NHAI is the government highway authority; NHIT is a separate InvIT that holds operational road assets and issues both units and NCDs.
Who manages NHIT?
NHIT is managed by National Highways Infra Investment Managers Private Limited, with operations handled by a project manager, both linked to NHAI and the Ministry of Road Transport and Highways.
How is an InvIT different from a REIT?
An InvIT holds infrastructure assets such as roads or power lines, while a REIT holds real estate. Both distribute income from underlying assets but face different regulatory and revenue structures.
How are NHIT investments regulated in India?
NHIT operates under SEBI's InvIT Regulations, with its NCDs additionally subject to SEBI's debt securities disclosure norms.
What factors can affect the performance of NHIT investments?
Traffic volumes, interest rate movements, regulatory or concession changes, and litigation outcomes can all influence distributions, unit prices, and yields.
