Financial Sector Risk Taxonomy: Credit, Market, Liquidity, and Operational Risk Architecture

• Credit Risk: The potential that a bank borrower or counterparty will fail to meet its payment obligations in accordance with agreed terms, causing financial loss. Encompasses Default Risk, Exposure Risk, Recovery Risk, and Credit Migration / Downgrade Risk.
• Market Risk: The risk of financial loss arising from adverse movements in market prices and rates across trading and banking books. Decomposed into:
  • Interest Rate Risk in Banking Book (IRRBB): Fluctuations in interest yields affecting Net Interest Income (NII) and market value of fixed-income assets.
  • Foreign Exchange (Forex) Risk: Currency parity fluctuations impacting foreign currency loans, export credits, and offshore borrowings.
  • Equity Risk: Volatility in the market value of shares and equity-linked investments held by the treasury.
  • Commodity Risk: Price swings in precious metals or agricultural commodities financed through warehouse receipts.
• Liquidity Risk: The inability of a bank to fund asset increases and meet debt obligations as they come due without incurring unacceptably catastrophic losses. Subdivided into:
  • Funding Liquidity Risk: Inability to replace maturing deposits or meet sudden depositor withdrawals.
  • Market Liquidity Risk: Inability to rapidly liquidate asset holdings (e.g., government securities) in wholesale secondary markets without severe price discounts.
• Operational Risk: The risk of loss resulting from inadequate or failed internal processes, people, and systems, or from external events (IT outages, internal fraud, cyber intrusions, natural disasters).
• Pillar 2 / Non-Financial Risks: Strategic Risk (flawed business plans), Reputational Risk (public erosion of confidence), and Legal & Compliance Risk (statutory fines and regulatory sanctions).

The operational execution of ALM is vested in the Asset-Liability Committee (ALCO), an executive-level board subcommittee typically chaired by the Managing Director & CEO, comprising the Chief Financial Officer (CFO), Chief Risk Officer (CRO), Treasury Head, Chief Economist, and Credit Business Heads:

• Balance Sheet Structuring: Deciding deposit tenure mixes, pricing of retail fixed deposits, MCLR/EBLR base lending rate resets, and loan portfolio growth rates.
• Liquidity Profiling & Contingency Funding: Monitoring compliance with RBI prudential liquidity ratios:
  • Liquidity Coverage Ratio (LCR): Holding sufficient unencumbered High-Quality Liquid Assets (HQLA) to cover 100% of net cash outflows over a 30-day extreme stress scenario.
  • Net Stable Funding Ratio (NSFR): Ensuring that long-term assets are funded with a minimum proportion of stable long-term liabilities (Available Stable Funding / Required Stable Funding ≥ 100%).
• Contingency Funding Plan (CFP): Designing emergency action triggers, collateral repo lines with RBI, and asset securitization protocols for managing sudden liquidity panics.

The RBI mandates plotting assets and liabilities across 8 sequential time buckets: Next day, 2–7 days, 8–14 days, 15–30 days, 31 days to 2 months, 2–3 months, 3–6 months, 6 months to 1 year, 1–3 years, 3–5 years, and Over 5 years.

• Structural Liquidity Mismatch: In any time bucket $k$, the net liquidity gap is: $$ ext{Net Liquidity Gap}_k = ext{Cash Inflows (Maturing Assets)}_k - ext{Cash Outflows (Maturing Liabilities)}_k$$ $$ ext{Negative Gap (Deficit): Outflows } > ext{ Inflows} implies ext{Bank must borrow in money markets to repay maturing deposits.}$$ $$ ext{Positive Gap (Surplus): Inflows } > ext{ Outflows} implies ext{Bank holds excess cash that must be deployed profitably.}$$ RBI Prudential Tolerance: The net cumulative negative mismatch in the 1–14 day and 15–30 day buckets cannot exceed 20% of cumulative cash outflows.
• Interest Rate Sensitivity Gap (Repricing Gap): $$ ext{Repricing Gap (GAP)} = ext{Rate-Sensitive Assets (RSA)} - ext{Rate-Sensitive Liabilities (RSL)}$$ $$ ext{Gap Ratio} = rac{ ext{RSA}}{ ext{RSL}}$$
  • Asset-Sensitive (Positive Gap, RSA > RSL): If interest rates rise, NII increases because assets reprice faster than liabilities. If rates fall, NII contracts.
  • Liability-Sensitive (Negative Gap, RSA < RSL): If interest rates rise, NII contracts because expensive deposits reprice faster than fixed-rate loans. If rates fall, NII expands.
