How AIF Debt Funds Are Reshaping Indian Mid-Market Credit

Fifteen years ago, the Indian corporate debt market was a two-lane road. Banks on one side (cheap, slow, conservative). NBFCs on the other (faster, more flexible, more expensive). Most mid-market companies picked between the two based on which lane fit their situation. The choice was constrained but understood.

That's no longer the market. Since roughly 2019, a third lane has opened up: AIF Category II debt funds and adjacent private credit strategies. These vehicles have absorbed a meaningful share of the mid-market lending that used to belong to banks and NBFCs — and they've done it by offering something neither of the incumbents could: customised structures at scale. This post walks through what they are, how they price, and when they're the right answer.

What an AIF debt fund actually is

An AIF Category II is a SEBI-registered pooled investment vehicle. Under SEBI (AIF) Regulations 2012, Category II AIFs invest in private companies and can't take on leverage themselves (with narrow operational exceptions). Category II debt funds specifically deploy capital into private credit — structured NCDs, mezzanine, senior secured facilities, real estate credit, and similar instruments.

The capital pool comes from a defined set of qualified investors: insurance companies, family offices, HNIs, sovereign investors, endowments, and pension funds. Fund tenors are typically 5–8 years with a 3–4 year investment period. Managers take management fees (1.5–2% p.a.) and performance fees / carry (15–20% above a hurdle rate, typically 8–10%).

The economic model is different from a bank or NBFC in one crucial way: AIF debt funds are answering to investors expecting a specific IRR, not to shareholders or regulators expecting quarterly earnings. That drives everything about how they deploy.

Why they've grown so fast

Three secular tailwinds have made AIF debt fund AUM grow ~30% CAGR since 2019:

1. Banks pulled back post-IL&FS and Yes Bank. Bank credit to mid-market corporates tightened materially after 2018. Not just in willingness — RBI norms around large-exposure limits, provisioning, and priority-sector allocation reduced the amount of capital banks could deploy into non-standard mid-market credit. The gap that opened up needed to be filled.

2. NBFCs got constrained by their own funding. When bank lending to NBFCs became more conservative (also post-IL&FS), NBFCs' cost of funds rose and their ability to hold long-tenor assets got squeezed. NBFCs are structurally short-tenor lenders; longer-tenor mid-market credit needed a different vehicle.

3. Investor demand for yield. Family offices and HNIs, faced with FD rates at 6–7% and equity market volatility, wanted 12–15% yields with reasonable credit risk. AIF Cat II debt funds delivered exactly that. Capital flowed in.

The result is a new lender pool with a very different value proposition than banks or NBFCs.

What AIF debt funds do well

The best AIF debt funds don't compete with banks on price. They compete on structure — doing deals banks won't or can't touch.

Where AIF debt funds are the right lender pool:

1. Longer tenor than banks/NBFCs will offer

Banks cap corporate term loans at 5–7 years typically. NBFC term loans are usually 3–5 years. AIF debt funds regularly do 5–8 year facilities, sometimes longer with bullet structures. For capex that pays back over long horizons — real estate development, infrastructure, capital-intensive manufacturing — the tenor match matters more than the coupon.

2. Structured cash flows

Moratoriums (interest-only or full deferral for the first 12–24 months). Step-up interest schedules. Bullet or partial-bullet repayment structures. Cash-flow-linked amortisation. Banks are rigid on structure; NBFCs somewhat less so; AIF debt funds are the most flexible pool in the market.

3. Non-standard credits

Real estate LRD against annuity-style rental cash flows. Promoter loans against listed shares. LBO / acquisition financing. Special-situations debt (turnaround, distressed, restructuring). Sector-focused mandates (healthcare, education, renewables, real estate). Each of these has AIF fund specialists that price and structure better than a generalist bank or NBFC.

4. Larger ticket sizes

A single AIF debt fund can commit ₹50–500 Cr to a single deal. That's often larger than any single NBFC will do bilaterally, and comparable to bank consortium arrangements — but without the coordination overhead. For growth-stage companies or large restructurings, this scale matters.

5. Mezzanine and quasi-equity structures

Anything that sits above senior debt in the capital structure — subordinated NCDs, PIK-plus-cash structures, warrant-attached debt — happens primarily in the AIF space now. Banks don't do it. Most NBFCs won't. AIF Cat II is the natural home for it.

What they don't do well

To be honest about the trade-offs, AIF debt funds are the wrong lender pool when:

• You're rate-sensitive. AIF debt is priced 200–500 bps above equivalent NBFC debt, and 400–800 bps above bank debt. For plain-vanilla financing at competitive rates, they're not the answer.
• You want revolving working capital. AIFs deploy term capital, not revolving lines. Working capital belongs at banks (or NBFCs).
• Ticket size is small. Below ₹15–20 Cr, AIF fund transaction costs don't justify the ticket. NBFCs handle small-mid tickets more efficiently.
• You need speed. AIF processes typically run 8–12 weeks — comparable to banks, slower than NBFCs. Not the right pool for urgent capital.
• You'll refinance quickly. AIF facilities often have 24–36 month lock-ins and 3–5% prepayment penalties. Expensive to exit early.

How pricing actually works

AIF debt fund pricing has more moving parts than bank/NBFC pricing. Understanding what you're actually paying matters.

Base coupon — typically 12–16% p.a., paid in cash. Higher for unsecured/mezzanine, lower for well-secured senior.

PIK (Payment-in-Kind) interest — additional interest that accrues to the outstanding rather than being paid in cash. Common in mezz structures. A "12% cash + 4% PIK" facility carries all-in interest cost of 16% but requires only 12% cash servicing during tenor — with the PIK compounding into the maturity balloon.

Fees — Arrangement fees (1–2%), commitment fees on undrawn (0.5–1%), monitoring fees (0.1–0.3% annual), prepayment penalties (2–5%). All of these get netted into the effective yield the fund is targeting.

Warrants / equity kickers — some structures include warrants exercisable at low strike prices. Rare in pure debt but common in "growth debt" and quasi-equity.

When comparing AIF quotes, always calculate all-in IRR to the lender, not just the coupon. Two facilities with identical coupons can have materially different all-in yields depending on fees, PIK, and prepayment terms.

Who the major players are

The Indian AIF Cat II debt space in 2026 has three broad clusters:

Bank-affiliated fund managers — Kotak Alternative Assets, ICICI Prudential AMC (alternatives arm), Edelweiss Alternatives, HDFC Capital. These leverage the parent bank's credit infrastructure and relationships; tend to be more conservative underwriters but at competitive pricing.

Independent alternatives firms — ASK Group, IIFL Alternate Asset, Piramal Alternatives, and several specialist funds. Broader mandate diversity; often more willing on non-standard credit.

Private credit specialists — Vivriti Capital, Trust Investment Advisors, Neo Wealth, Multiples Alternate Asset, several family-office-backed funds. Focus specifically on mid-market credit and mezzanine; typically fastest and most flexible on structure, at the top end of the pricing range.

Each cluster has different sweet spots — sector focus, ticket size, structure preferences. Choosing the right fund matters as much as choosing between AIF and NBFC in the first place.

What this means for mid-market borrowers

Three practical implications:

1. Your capital options are wider than you think. If your primary banker declines a raise, that's no longer the end of the story — it's the beginning of a different conversation. AIF debt funds have appetite for many credits banks won't do. But you need to know which funds to approach, which is where advisors earn their keep.

2. Instrument choice matters more. With three lender pools (banks, NBFCs, AIF debt funds) each with different sweet spots, matching instrument to lender pool matters more than it used to. A term loan and an AIF mezz can fund the same nominal ₹50 Cr — but the trade-offs on cost, tenor, structure, and future flexibility are meaningfully different.

3. Blended stacks are the new normal. Sophisticated mid-market balance sheets now typically have bank working capital + NBFC term debt + AIF structured debt sitting side-by-side. Each layer is doing what it's best at. Building this stack is a design exercise — not a one-off placement.

Common questions

Do AIF debt funds report to CIBIL?

Yes, most Category II AIFs that lend under standard NCD or loan structures report to credit bureaus. Some very customised private-credit structures don't get reported in the same way (they're not traditional bank/NBFC facilities), but this is increasingly the exception.

What's the minimum ticket size for an AIF debt fund?

Practically ₹15–25 Cr for most funds — the transaction costs (legal, due diligence, monitoring) don't pencil below that. Some specialised smaller-ticket funds exist but they're the minority. Below ₹15 Cr, NBFCs remain the more efficient route.

Are AIF debt facilities more expensive than bank/NBFC?

Yes, by design. AIF debt funds target 12–15% net IRRs to their investors after fees, which means gross yields on deployed capital are typically 14–18%. That's 200–500 bps above equivalent NBFC pricing and 400–800 bps above bank pricing. What you're paying for is structural flexibility, tenor, and access to a lender that will do the deal at all.

How does an AIF-led NCD differ from a bank-led NCD?

Legally, the NCD instrument is similar. The difference is who's buying: AIF investors have different return expectations, tolerance for structure, and hold periods than banks. AIF-led issuances are often bilateral (single fund taking the whole issuance) vs bank NCDs which are often broader placements. Documentation is broadly similar but AIF issuances often include more custom terms.
