Comprehensive Guide to the Indian Debt Market: Chapter 1 Notes (Part Two)

This report provides high-quality, authoritative short notes for the second half of Chapter 1 from the NISM Series XXII: Fixed Income Securities Workbook, covering Credit Rating Agencies, Monetary Policy, and Market Dynamics.

CHAPTER 1: OVERVIEW OF THE INDIAN DEBT MARKET (CONTINUED)

1.5 Role of Credit Rating Agencies (CRAs)

Credit risk is the possibility of default arising from a borrower's failure to make required interest or principal payments. While sovereign domestic debt is perceived as "credit risk free," non-government debt pricing is dictated by the issuer’s creditworthiness.

1. Function of CRAs

• Standardisation: CRAs standardize and summarize voluminous information about issuers into independent views on future debt performance.
• Regulation: In India, CRAs are regulated by SEBI under the SEBI (Credit Rating Agencies) Regulations, 1999.
• Grading System: They use letter grades: "AAA" indicates the highest safety, while "D" signifies Default.

2. Rating Categories

• Investment Grade: AAA to BBB-.
• Non-investment (Junk) Grade: BB+ to CCC-.
• Default Rating: D.
• Short-term Scale: A1+ to D.

3. Key Concepts in Credit Rating

• Issuer Default Rating (IDR): Refers specifically to the probability of an issuer defaulting.
• Probability of Default (PD): A quantitative measure based on historical annual default rates of bonds in specific rating categories.
• Rating Migration: The change in a rating (upgrade or downgrade) before maturity.
• Migration Matrix: A tool used to understand market stability. For example, data shows 87.19% of "AAA" companies typically retain their rating over one year.

4. Strategic Importance

• For Investors: Identification of risk, independent opinions, saving of time/resources, and intensive surveillance.
• For Issuers: Easier debt sales, lower borrowing costs, wider market access, and image building.
• Market Impact: A downgrade impacts the spread over the risk-free yield curve, potentially causing mark-to-market losses.

1.6 Role of Monetary Policy in Debt Markets

Bond yields are significantly affected by the Reserve Bank of India’s (RBI) monetary policy, which at its core is about determining interest rates.

1. Policy Transmission

• Monetary Policy Transmission: The process where changes in policy rates affect bank borrowing/lending rates, which are then passed to customers.
• Risk-Free Rate: Sovereign interest rates define the risk-free rate, impacting the price and demand for all financial securities.
• Economic Steering: In recessions, the RBI lowers rates to foster growth; during asset bubbles, it raises rates to moderate demand.

2. Institutional Framework

• Monetary Policy Committee (MPC): A 6-member committee chaired by the RBI Governor that determines policy rates to achieve inflation targets.
• Inflation Target: The government-notified target is 4% CPI inflation (with a tolerance range of 2% to 6%).
• Operating Target: The primary target is the Weighted Average Call Rate (WACR), which should ideally move around the Repo rate.

3. Key Monetary Policy Instruments

• Repo Rate: The fixed rate at which RBI lends funds to banks against securities.
• Reverse Repo Rate: The rate at which RBI borrows funds from banks.
• Liquidity Adjustment Facility (LAF): Consists of overnight and term repo auctions to manage liquidity and set market benchmarks.
• Marginal Standing Facility (MSF): A safety valve allowing banks to borrow overnight at a penal rate by dipping into their SLR portfolio.
• Bank Rate: The rate for buying/rediscounting bills of exchange, aligned with the MSF rate.
• Cash Reserve Ratio (CRR): The share of NDTL banks must maintain as a daily balance with the RBI.
• Statutory Liquidity Ratio (SLR): The share of NDTL banks must maintain in safe assets like G-Secs, gold, and cash.
• Open Market Operations (OMOs): Outright purchase/sale of G-Secs for liquidity management.
• Market Stabilization Scheme (MSS): Using short-dated G-Secs/T-Bills to absorb enduring surplus liquidity from capital inflows.
• Long Term Repo Operations (LTROs): Term repos (1 to 3 years) providing durable liquidity at reasonable costs.

1.7 Evolution of Debt Markets

India has a bank-dominated system, but structural changes are improving debt market access to reduce bank dependence.

1. Global Context

• Global debt topped 322% of GDP by 2019.
• Mature markets reached 383% of GDP, while emerging markets saw a surge driven by corporate debt.
• Most global corporate debt markets are Over the Counter (OTC) and wholesale in nature.

2. Indian Corporate Bond Market

• Transactions are executed bilaterally and reported to exchanges for settlement.
• Mutual Funds and Alternative Investment Funds (AIFs) are playing a growing role in channelizing savings into debt.
• Foreign Portfolio Investors (FPIs): Regulators have increased investment limits and relaxed maturity requirements (now 1-year minimum) to stimulate foreign flow.

1.8 Market Dynamics

While the Indian market has grown, it remains dominated by government debt.

1. Market Characteristics

• Penetration: Corporate bonds as a percentage of GDP remain low compared to developed nations.
• Fragmentation: Corporate bonds are highly fragmented. As of Dec 2019, there were 24,010 outstanding corporate bonds (average size ₹131 crore) vs. 116 Central G-Secs (average size ₹54,138 crore).
• Liquidity: This fragmentation causes secondary market illiquidity, which SEBI is addressing through reissuances.

2. Trading and Issuance Trends

• Secondary Trading: Corporate bond trading volumes rose 8x between 2009-10 and 2019-20, though they still only represent 12% of G-Sec volumes.
• Sector Dominance: Finance and infrastructure companies account for nearly 90% of total issuances.
• Credit Quality: The market is dominated by high-credit issuers; 71% of issuances in 2019-20 were rated ‘A’ or higher, with ‘AAA’ holding a 44% share.

Important Terms for Exam Preparation

Key Takeaways

• Credit ratings provide a simplified, standardized measure of default probability for investors.
• The RBI uses WACR to signal its monetary stance and manage liquidity via instruments like the Repo rate and SLR.
• The Indian corporate bond market is characterized by high fragmentation and a heavy reliance on the finance and infrastructure sectors.
• Secondary market trading in corporate bonds is picking up but remains significantly smaller than the G-Sec segment.
