In September 2018, IL&FS | a large NBFC with ₹91,000 crore of debt | defaulted. Within weeks, the entire NBFC sector faced a liquidity crisis. Mutual funds stopped lending. Interest rates for NBFCs spiked. Housing finance companies saw their stocks fall 50-70%. The contagion spread to real estate, auto, and consumer durables. All because one large credit institution couldn't roll over its short-term paper. Understanding the credit cycle is not optional for Indian equity investors.

How India's credit cycle works

The credit cycle follows a predictable pattern:

RBI Annual Report | credit growth and banking sector analysis
The four-phase credit cycle, India edition
Each phase lasts 2 to 4 years, and banks behave very differently in each
PHASE 1
Expansion
RBI cuts rates, credit growth 15 to 20%, NPAs fall, bank stocks outperform
PHASE 2
Peak
Standards loosen, leverage builds, asset quality still looks pristine on surface
PHASE 3
Contraction
Rate hike or credit event, liquidity tightens, weakest NBFCs crack first
PHASE 4
Cleanup
NPA recognition, provisioning spikes, bank earnings bottom, stocks base out
India has completed two full cycles since 2000: 2003 to 2013 (cleanup 2014 to 2020), and 2020 to now (current phase: late expansion per RBI FSR Dec 2025).

The NBFC sector | India's shadow banking system

NBFCs (Non-Banking Financial Companies) are financial institutions that lend but don't hold banking licences. They cannot take demand deposits (unlike banks) but raise money through commercial paper, bonds, and bank loans. India has thousands of NBFCs, from large listed entities (Bajaj Finance, Cholamandalam, Shriram Finance) to small micro-finance institutions.

NBFCs serve segments that banks underserve: vehicle financing (trucks, tractors, two-wheelers), microfinance, gold loans, housing finance for self-employed borrowers, and MSME lending. As of 2024, NBFCs account for roughly 25% of total credit in India | a systemic role that makes their health critical to the broader economy.

The IL&FS crisis | a case study in credit cycle reversal

IL&FS (Infrastructure Leasing and Financial Services) was a large, AAA-rated NBFC that primarily borrowed short-term (commercial paper, bonds) and lent long-term (infrastructure projects). When short-term funding became unavailable in 2018, it couldn't roll over debt. The default shocked the market for two reasons:

The DHFL story (2019): DHFL (Dewan Housing Finance Corporation) followed a similar path | asset-liability mismatch, governance issues, eventual default and resolution. Combined, IL&FS and DHFL demonstrated that in India's credit system, asset-liability mismatch in NBFCs is the most persistent risk. Short-term borrowing + long-term lending = structural vulnerability during any liquidity crunch.

NPA cycle | how bad loans move through the system

The NPA (Non-Performing Asset) cycle refers to the rise and fall of bad loans in the banking system. In India, the most recent full NPA cycle ran from ~2012-2022:

Investor implication of the NPA cycle: Banks provisioning for NPAs report lower profits but build cleaner balance sheets. Once NPA recognition peaks and provisioning coverage is high, it signals the beginning of a bank earnings recovery cycle. This is one of the most reliable medium-term signals for banking sector outperformance | provisioning peak → credit cost normalisation → earnings recovery → re-rating.

What NBFCs actually lend against, India
NBFC credit book composition, approximate FY25
Retail secured lending (vehicle + gold + housing) now dominates. That is structurally safer than the wholesale real estate book that blew up in 2018.
  • Vehicle finance (Mahindra Finance, Shriram)26%
  • Housing finance (HDFC merger now in bank, Bajaj Housing)20%
  • MSME and business loans16%
  • Gold loans (Muthoot, Manappuram)14%
  • Consumer finance (Bajaj Finance core book)12%
  • Infrastructure and wholesale (the 2018 trouble zone)12%

Credit growth as a leading economic indicator

RBI publishes weekly bank credit data. System credit growth (year-on-year change in total bank credit outstanding) is one of the best real-time proxies for economic momentum:

Credit signals in RupeeCase

RupeeCase's macro regime model monitors quarterly system credit growth from RBI data. Accelerating credit growth is a positive regime signal | particularly for financial sector factor exposure. Decelerating credit growth triggers a more defensive positioning in the Allcap Multi Asset. The credit cycle dashboard is available at invest.rupeecase.com.

TK | From the 2018 NBFC crisis

I remember September 2018 very clearly. We were watching short term CP (commercial paper) yields for NBFCs spike in real time, Dewan Housing, IL&FS, Indiabulls, all rolling three month paper that suddenly nobody wanted to take. The equity market had not repriced yet, but the bond desk already knew. If you track one thing to read credit stress in India, it is the spread between AAA NBFC three month CP and T bills. When that spread blows out 200 basis points in a week, something is breaking. Do not wait for Moneycontrol to tell you.

Glossary

Key terms | Module 7.7
NBFC
Non-Banking Financial Company | lends but cannot take demand deposits. Raises funds via bonds, commercial paper, bank loans. Accounts for ~25% of India's total credit. Vulnerable to asset-liability mismatches.
NPA
Non-Performing Asset | a loan where the borrower hasn't paid principal or interest for 90+ days. Banks must provision (set aside) capital for NPAs, reducing reported profits.
Asset-liability mismatch
When a financial institution borrows short-term (e.g., 3-month commercial paper) and lends long-term (e.g., 5-year infrastructure loans). The core vulnerability that triggered the IL&FS crisis.
IBC
Insolvency and Bankruptcy Code (2016) | India's time-bound corporate insolvency resolution framework. Changed the power dynamic from debtor-in-control to creditor-in-control. Enabled the NPA resolution cycle of 2018-2022.
Evergreening
When banks extend new loans to struggling borrowers so they can repay old loans | preventing NPA recognition. Delayed but amplified India's NPA problem until RBI's 2015-16 AQR forced recognition.

A note from the author
Why this matters

The IL&FS crisis in 2018 and the subsequent NBFC contagion taught every Indian market participant a brutal lesson about credit cycles. I saw systematic strategies that ignored credit conditions lose years of gains in a matter of weeks. Understanding how the credit cycle works in India, and especially the outsized role NBFCs play in transmitting liquidity, is critical for building strategies that do not blow up when the cycle turns.
