Unit 4: Bank investments - Subjective Questions

Bank Investment Policy refers to the set of guidelines, principles, and strategies framed by a bank's Board of Directors to govern the deployment of surplus funds into various investment avenues in a safe, liquid, and profitable manner.

Objectives of Investment Policy:

• Safety of funds: Protecting the principal amount invested.
• Liquidity: Ensuring investments can be converted into cash quickly to meet obligations.
• Profitability: Earning a reasonable return on surplus funds.
• Compliance: Meeting statutory requirements like SLR.
• Diversification: Spreading risk across instruments and sectors.

Factors influencing Investment Policy:

• Regulatory requirements (CRR, SLR norms by RBI).
• Liquidity needs of the bank based on deposit maturity patterns.
• Interest rate scenario and expectations in the market.
• Capital adequacy position of the bank.
• Risk appetite of the management.
• Economic and market conditions.

A well-defined investment policy balances the conflicting goals of safety, liquidity, and profitability while ensuring regulatory compliance.

Statutory Liquidity Ratio (SLR) is the minimum percentage of a bank's Net Demand and Time Liabilities (NDTL) that it must maintain in the form of liquid assets such as cash, gold, and approved government securities before providing credit to customers.

Mathematical representation:

Purpose of SLR:

• To ensure the solvency and liquidity of banks.
• To control the expansion of bank credit.
• To ensure banks invest in government securities, aiding government borrowing.
• To act as a cushion against bank failures.

Qualifying Assets for SLR:

• Cash in hand (excluding CRR balance).
• Gold valued at current market price.
• Approved securities — Central and State Government securities.
• Treasury Bills of the Government of India.
• Other instruments notified by RBI from time to time.

SLR is a key monetary policy tool used by RBI to regulate liquidity in the banking system.

Both CRR and SLR are statutory reserve requirements imposed by the RBI, but they differ in several respects:

Key point: CRR primarily controls the liquidity in the economy, while SLR ensures the solvency of banks and channels funds to the government. Both are important instruments of monetary policy.

Non-SLR Investments are investments made by banks in instruments that do not qualify for maintaining the Statutory Liquidity Ratio. These are typically made to enhance profitability and diversify the investment portfolio beyond government securities.

Categories of Non-SLR Investments:

• Commercial Papers (CP): Short-term unsecured promissory notes issued by corporates.
• Certificates of Deposit (CD): Issued by banks and financial institutions.
• Corporate Bonds and Debentures: Debt instruments issued by companies.
• Shares/Equity: Investment in equity of companies (within regulatory limits).
• Units of Mutual Funds.
• Preference Shares.
• Bonds of Public Sector Undertakings (PSUs).
• Security Receipts issued by Asset Reconstruction Companies.

RBI Guidelines on Non-SLR Investments:

• Banks must restrict investment in unrated non-SLR securities.
• Investment in unlisted non-SLR securities is capped.
• Proper credit rating and due diligence are mandatory.
• Exposure limits must be observed to control concentration risk.

Non-SLR investments offer higher returns but carry higher credit and liquidity risks, hence require careful management.

As per RBI guidelines, banks are required to classify their entire investment portfolio into three categories based on the intent of holding:

1. Held to Maturity (HTM):

• Securities that the bank intends to hold until maturity.
• Generally not marked to market.
• Carried at acquisition cost (premium amortized over the period).
• Profit on sale is first taken to P&L and then appropriated to Capital Reserve.

2. Available for Sale (AFS):

• Securities that are neither HTM nor HFT.
• Marked to market at regular intervals (quarterly/half-yearly).
• Net depreciation is provided for, net appreciation is ignored.
• Offers flexibility in portfolio management.

3. Held for Trading (HFT):

• Securities acquired with the intention of trading to take advantage of short-term price movements.
• Marked to market at more frequent intervals (monthly or more).
• Must be sold within 90 days.
• Net depreciation is provided for, net appreciation is ignored.

Significance: This classification determines the valuation norms, provisioning requirements, and reflects the bank's intent, ensuring transparency in financial reporting.

Investment Valuation Norms prescribe how banks should value their investment portfolio for financial reporting, based on the classification category.

1. Held to Maturity (HTM):

• Valued at acquisition cost.
• If acquired at a premium, the premium is amortized over the remaining period to maturity.
• Generally not marked to market.
• Diminution in value of individual securities is recognized if permanent.

2. Available for Sale (AFS):

• Marked to market at periodic intervals (at least quarterly).
• Scrips are valued at market price.
• Net depreciation (if any) under each classification is fully provided for.
• Net appreciation is ignored (conservatism principle).

3. Held for Trading (HFT):

• Marked to market at frequent intervals (monthly or more frequent).
• Same treatment as AFS: net depreciation provided, net appreciation ignored.

Mark-to-Market (MTM) Concept:
Valuing securities at current market prices rather than book value, so that the portfolio reflects realistic/fair value.

Valuation Methods:

• Quoted securities: valued at market price.
• Unquoted government securities: valued on Yield to Maturity (YTM) basis using rates published by FIMMDA.

These norms ensure prudence, transparency, and realistic valuation of bank assets.

Credit Risk (also called default risk) is the risk that a borrower or issuer of a security will fail to meet its obligations of repaying principal and/or interest as per the agreed terms.

Causes of Credit Risk:

• Default by the issuer/counterparty.
• Deterioration in credit quality of the issuer (credit downgrade).
• Poor financial health of the borrower.
• Economic downturns affecting repayment capacity.
• Inadequate credit appraisal at the time of investment.

Measures to Manage Credit Risk:

• Credit rating: Investing only in rated instruments of good quality.
• Diversification: Spreading investments across issuers and sectors.
• Exposure limits: Setting caps on single-issuer and group exposures.
• Credit monitoring: Regular review of issuer's financial health.
• Collateral/Security: Investing in secured instruments.
• Provisioning: Making provisions for potential defaults.
• Credit derivatives: Using instruments like Credit Default Swaps (CDS).

Measurement: Credit risk is often quantified using Expected Loss:

where = Probability of Default, = Loss Given Default, = Exposure at Default.

Effective credit risk management is critical to protect the bank's capital and ensure stable earnings.

Concentration Risk is the risk arising from excessive exposure to a single counterparty, a group of related counterparties, a particular industry, sector, or geographic region. It represents a lack of adequate diversification in the portfolio.

Types of Concentration Risk:

• Single-name concentration: Large exposure to one issuer/borrower.
• Sectoral concentration: Heavy investment in one industry (e.g., real estate).
• Geographic concentration: Exposure focused in one region.

Importance of Controlling Concentration Risk:

• A default by a single large exposure can cause significant losses.
• Sector-specific downturns can affect a large portion of the portfolio.
• It can threaten the solvency and capital adequacy of the bank.

Mitigation Measures:

• Exposure limits: Prudential norms set by RBI (e.g., Large Exposure Framework).
• Diversification: Spreading investments across issuers, sectors, and geographies.
• Monitoring: Regular tracking of exposure levels against limits.
• Portfolio rebalancing: Reducing over-concentrated positions.
• Setting internal caps stricter than regulatory limits.

RBI's Large Exposure Framework limits a bank's exposure to a single counterparty to 20% of Tier-1 capital (extendable to 25% in exceptional cases). Managing concentration risk ensures resilience against localized shocks.

Liquidity Risk is the risk that a bank will not be able to meet its financial obligations as they fall due, without incurring unacceptable losses, due to the inability to convert assets into cash quickly or raise funds at reasonable cost.

Types of Liquidity Risk:

• Funding Liquidity Risk: Inability to meet cash flow obligations (deposit withdrawals, maturing liabilities).
• Market Liquidity Risk: Inability to sell/liquidate an asset without a significant price concession due to inadequate market depth.

Causes of Liquidity Risk:

• Mismatch between asset and liability maturities.
• Sudden large deposit withdrawals.
• Investment in illiquid securities.
• Adverse market conditions.

Strategies to Manage Liquidity Risk:

• Asset-Liability Management (ALM): Matching maturity profiles.
• Maintaining liquid assets: Holding government securities and cash.
• Liquidity Coverage Ratio (LCR): Maintaining high-quality liquid assets to cover 30-day net cash outflows.
• Net Stable Funding Ratio (NSFR): Ensuring stable funding over one year.
• Diversifying funding sources.
• Contingency funding plans.

LCR formula:

Effective liquidity management ensures the bank can honour its commitments and maintain depositor confidence.

Off-Balance Sheet (OBS) Risk arises from items that are not recorded on the bank's balance sheet as assets or liabilities but represent potential/contingent exposures that can affect the bank's financial position if they crystallize.

Examples of Off-Balance Sheet Items:

• Letters of Credit (LC).
• Bank Guarantees.
• Loan commitments (undrawn credit lines).
• Derivatives — forwards, futures, options, swaps.
• Forward exchange contracts.
• Underwriting commitments.
• Securitization exposures.

Risks Associated with OBS Items:

• Credit Risk: The counterparty may default, forcing the bank to honour the commitment.
• Market Risk: Adverse movements in interest rates or exchange rates affecting derivatives.
• Liquidity Risk: Sudden calls on guarantees or commitments requiring immediate funds.
• Operational Risk: Errors in processing or documentation.

Management of OBS Risk:

• Capital allocation: Converting OBS exposures to credit equivalents using Credit Conversion Factors (CCF).
• Monitoring and limits on contingent liabilities.
• Collateral and margins for derivative exposures.
• Disclosure in notes to accounts.

Under Basel norms, OBS exposures are converted into on-balance sheet equivalents for capital adequacy calculations:

OBS items can magnify risk significantly, hence require stringent monitoring.

Diversification is the strategy of spreading investments across various instruments, issuers, sectors, maturities, and geographies to reduce the overall risk of the portfolio. It is based on the principle of not putting all eggs in one basket.

Significance of Diversification:

• Risk reduction: Losses in one investment can be offset by gains in others.
• Stable returns: Reduces volatility in overall portfolio returns.
• Protection against defaults: Spreads credit risk across multiple issuers.
• Regulatory compliance: Helps meet exposure norms.

How Diversification Manages Risks:

• Credit Risk: Investing across multiple issuers reduces impact of any single default.
• Concentration Risk: Directly addressed by spreading across sectors and borrowers.
• Liquidity Risk: Mix of liquid and less-liquid assets ensures funds availability.
• Market/Interest Rate Risk: Staggering maturities (laddering) reduces reinvestment and price risk.

Dimensions of Diversification:

• By instrument: G-Secs, corporate bonds, CPs, CDs, equities.
• By maturity: Short, medium, and long-term.
• By sector/industry.
• By geography.

Limitation: Diversification reduces unsystematic (specific) risk but cannot eliminate systematic (market) risk. The benefit is captured through reduced portfolio variance when assets are not perfectly correlated. A well-diversified portfolio achieves an optimal balance of risk and return.

Mark-to-Market (MTM) is the practice of valuing securities in a bank's investment portfolio at their current market price rather than their original acquisition/book value. It reflects the fair value of investments at the reporting date.

Importance of MTM:

• Provides a realistic picture of the portfolio's value.
• Ensures transparency in financial statements.
• Reflects the impact of interest rate changes on investment value.
• Enables prudent provisioning for potential losses.
• Aligns with conservatism and prudence accounting principles.

Treatment of Net Depreciation and Appreciation:
For AFS and HFT categories, securities are grouped under classifications (e.g., Government securities, other approved securities, shares, bonds, etc.) and marked to market:

• Net Depreciation (market value < book value): Fully provided for in the Profit & Loss account.
• Net Appreciation (market value > book value): Ignored (not recognized as income).

This asymmetric treatment follows the principle of conservatism — recognizing anticipated losses but not unrealized gains.

For HTM: Securities are generally not marked to market; they are carried at acquisition cost with premium amortization.

Example: If a bank holds a bond at book value of ₹100 which now trades at ₹95, the ₹5 depreciation must be provided for. If it traded at ₹105, the ₹5 appreciation is ignored.

MTM ensures that the portfolio value reflects market realities and losses are not understated.

Banks face multiple interrelated risks in their investment activities. A comparison of three major risks:

Interrelationship:

• Concentration risk can amplify credit risk — if a large exposure defaults, losses are severe.
• Credit downgrades can trigger liquidity problems if assets become hard to sell.
• Poor liquidity can force sale of concentrated holdings at a loss.

Conclusion: While distinct, these risks are interconnected. An integrated risk management framework is essential to address them holistically and protect the bank's solvency and stability.

Sound bank investment management involves deploying funds in a manner that achieves the best balance among competing objectives while complying with regulations.

Objectives of Investment Management:

• Safety of principal invested.
• Liquidity to meet obligations.
• Profitability through optimal returns.
• Regulatory compliance (SLR, exposure norms).
• Risk diversification.

Principles of Sound Investment:

• Safety: Prefer high-quality, low-risk securities.
• Liquidity: Maintain adequate convertible assets.
• Profitability: Seek reasonable returns.
• Diversification: Spread risk.
• Marketability: Invest in tradable securities.
• Tax efficiency: Consider post-tax returns.

The Safety-Liquidity-Profitability Trade-off:
These three objectives often conflict:

• Safe and liquid assets (e.g., T-Bills, G-Secs) usually offer lower returns.
• High-return assets (e.g., corporate bonds, equities) carry higher risk and may be less liquid.

Balancing Mechanism:

• Maintain a core of safe, liquid assets (government securities) for SLR and liquidity needs.
• Allocate a portion to higher-yielding non-SLR assets for profitability within risk limits.
• Use laddering of maturities to balance liquidity and return.
• Continuously monitor and rebalance based on market conditions.

The art of investment management lies in finding the optimal mix that maximizes returns for an acceptable level of risk and liquidity — often described as the 'magic triangle' of banking.

Treasury Bills (T-Bills):

• Short-term money market instruments issued by the Government of India (RBI on its behalf).
• Issued at a discount and redeemed at face value.
• Available in tenors of 91 days, 182 days, and 364 days.
• Zero-coupon instruments (no periodic interest).
• Highly liquid and risk-free (sovereign backing).

Government Securities (G-Secs):

• Long-term debt instruments (dated securities) issued by the central/state governments.
• Carry a fixed or floating coupon paid periodically.
• Maturity ranges from 1 year to 40 years.
• Considered risk-free due to sovereign guarantee.

Return on T-Bill (Yield):

Role in SLR Investments:

• Both T-Bills and G-Secs are approved securities that qualify for maintaining SLR.
• They provide a safe and liquid avenue to park funds while earning returns.
• Help banks meet statutory requirements without sacrificing much return.
• Being highly liquid, they can be quickly sold or used in repo transactions for liquidity.
• They form the backbone of a bank's investment portfolio due to safety and marketability.

These instruments combine safety, liquidity, and regulatory compliance, making them ideal for SLR purposes.

Shifting of securities refers to the transfer of investments from one classification category (HTM, AFS, HFT) to another. Since the categories reflect the bank's intent of holding, any change in intent may necessitate shifting.

RBI Norms Governing Shifting:

1. Timing of Shifting:

• Banks are permitted to shift investments to/from HTM with the approval of the Board of Directors, generally once a year, usually at the beginning of the accounting year.

2. Valuation at the time of shifting:

• Securities shifted should be transferred at the lower of acquisition cost / book value / market value on the date of transfer.
• Any depreciation on such shifting must be fully provided for.

3. Shifting between AFS and HFT:

• Shifting from AFS to HFT or vice versa may be done with the approval of appropriate authority (Board/ALCO/Investment Committee).

4. HTM Ceiling:

• Investments in the HTM category are subject to a ceiling (as prescribed by RBI from time to time) as a percentage of total investments.

Purpose of Shifting Rules:

• Prevent banks from manipulating profits by shifting to avoid MTM losses.
• Ensure transparency and prudence in valuation.
• Reflect genuine changes in investment intent.

Example: If a security is shifted from AFS to HTM and its market value is below book value, the depreciation must be recognized before the shift.

These norms maintain integrity in investment accounting and prevent window dressing.

RBI has prescribed prudential guidelines to regulate banks' investments in Non-SLR securities to ensure safety and prevent excessive risk-taking.

Key RBI Guidelines on Non-SLR Investments:

• Credit Rating: Banks should generally invest only in rated non-SLR securities. Investment in unrated securities is restricted/capped.
• Listing Requirement: Preference for listed securities; investment in unlisted non-SLR securities is subject to a ceiling (as a percentage of total non-SLR investments).
• Minimum Rating: Investments must meet a minimum investment-grade rating.
• Internal Rating: Banks must have systems for internal credit assessment in addition to external ratings.
• Fixed Income Securities: Must be in the form of listed/rated instruments where possible.
• Disclosure and Reporting: Periodic reporting of non-SLR portfolio to the Board and RBI.
• Due Diligence: Proper appraisal before investment.
• Review Mechanism: Regular review of the portfolio by the Board.

Why These Restrictions Are Necessary:

• Non-SLR investments carry higher credit and default risk than government securities.
• To protect depositors' funds from risky investments.
• To prevent concentration in low-quality securities.
• To ensure liquidity is not compromised.
• To maintain the soundness and stability of the banking system.
• To avoid banks acting as unchecked financiers of corporates.

These prudential norms strike a balance between allowing banks to earn higher returns and protecting the financial system from undue risk.

Interest Rate Risk is the risk that changes in market interest rates will adversely affect the value of a bank's investments and its net interest income.

Impact of Interest Rate Changes on Investment Value:
There is an inverse relationship between interest rates and bond prices:

• When interest rates rise, the price of existing fixed-rate securities falls (because newer securities offer higher yields).
• When interest rates fall, the price of existing securities rises.

where = coupon, = face value, = market yield, = periods. As increases, price decreases.

Measures of Interest Rate Sensitivity:

• Duration: Measures the sensitivity of a bond's price to interest rate changes.
• Modified Duration:
• PV01 (Price Value of a Basis Point): Change in value for a 1 basis point change in yield.

Types of Interest Rate Risk:

• Price/Market risk: Loss in portfolio value due to rising rates.
• Reinvestment risk: Lower returns when reinvesting at falling rates.

Management of Interest Rate Risk:

• Duration management: Adjusting portfolio duration based on rate outlook.
• Laddering maturities: Staggering investments across maturities.
• Gap analysis: Analyzing rate-sensitive assets vs liabilities.
• Hedging: Using interest rate derivatives (swaps, futures).
• Classification into HTM: Reduces MTM impact.

Effective interest rate risk management protects both the portfolio value and the bank's earnings.

Credit Conversion Factor (CCF) is a percentage factor applied to the notional/face amount of an off-balance sheet (OBS) item to convert it into an on-balance sheet credit equivalent amount for the purpose of calculating capital requirements under Basel norms.

Need for CCF:
Off-balance sheet items (guarantees, LCs, commitments, derivatives) represent contingent exposures that may convert into actual on-balance sheet exposures if the contingency materializes. CCF estimates the likelihood and extent of this conversion.

Formula:

This credit equivalent is then multiplied by the risk weight of the counterparty to arrive at the Risk-Weighted Asset (RWA):

Typical CCF Values (illustrative, as per Basel/RBI):

• Direct credit substitutes (e.g., financial guarantees): 100%
• Performance guarantees, bid bonds: 50%
• Documentary Letters of Credit (short-term, self-liquidating): 20%
• Commitments with original maturity up to 1 year: 20%
• Commitments over 1 year: 50%
• Unconditionally cancellable commitments: 0%

Example: A bank issues a financial guarantee of ₹100 crore (CCF = 100%) to a corporate with 100% risk weight.

• Credit Equivalent = ₹100 crore × 100% = ₹100 crore
• RWA = ₹100 crore × 100% = ₹100 crore
• Capital required (at 9%) = ₹9 crore

CCF ensures that OBS risks are adequately capitalized, maintaining the bank's capital adequacy and financial soundness.

Asset-Liability Management (ALM) is a strategic framework for managing the risks that arise due to mismatches between a bank's assets and liabilities in terms of maturity, interest rate, and currency. It plays a crucial role in managing investment-related risks.

Objectives of ALM:

• Manage liquidity risk.
• Manage interest rate risk.
• Optimize net interest income (NII) and net interest margin (NIM).
• Ensure stable and sustainable earnings.

Key Components of ALM:

1. Liquidity Management:

• Structural Liquidity Statement: Maps cash inflows and outflows across time buckets.
• Identifies mismatches and ensures adequate liquidity in each bucket.

2. Interest Rate Risk Management:

• Gap Analysis: Measures difference between Rate Sensitive Assets (RSA) and Rate Sensitive Liabilities (RSL).
  
• Duration Gap Analysis: Measures sensitivity of net worth to rate changes.

3. ALCO (Asset-Liability Committee):

• Senior management committee responsible for ALM strategy and decisions.

4. Funds Transfer Pricing (FTP):

• Internal mechanism to price funds and allocate interest rate risk.

How ALM Manages Investment Risks:

• Liquidity Risk: By maintaining a balanced maturity profile and liquid investments.
• Interest Rate Risk: By managing the duration gap and rebalancing the portfolio.
• Concentration Risk: By monitoring exposure patterns across the balance sheet.

Regulatory Tools: LCR and NSFR (Basel III) are integral to ALM.

ALM provides an integrated, forward-looking approach to risk management, ensuring the bank remains solvent, liquid, and profitable under varying market conditions.
