The ALM
Mechanism
Synchronizing the balance sheet: Managing the margin between asset yield and liability cost through modern market-value accounting.

1. Repricing Bucket & Duration Inputs
2. Earnings Perspective (NII) & Economic Value (EVE)
The Reporting Paradigm Shift
Traditionally, banks utilized accrual accounting. However, in de-regulated interest regimes, the margin between asset yield and liability cost (Net Interest Margin) is highly volatile. Coordinated management is now a survival imperative.
Accrual Accounting
Can mask severe economic predicaments by ignoring the current market value of long-term assets and liabilities.
Market Value Accounting
Essential to recognize true financial worth during interest rate fluctuations. It provides an immediate "Economic Value" view.
Leveraged Capital Risk
Due to high leverage ratios, modest fluctuations in asset and liability values can lead to disproportionate erosions of core bank capital.

Read the Part 4 case study on how a massive rupiah devaluation in Indonesia exposed unhedged currency mismatches, triggering a severe asset-liability crisis.
Read Part 4 Case Study →The Role of ALCO
The **Asset Liability Committee (ALCO)** is the strategic heart of the bank, balancing profitability against institutional safety.
Return Focus
Monitoring ROA, ROE, and Net Interest Margin (NIM) to optimize Risk-Weighted Capital yield.
Liquidity Control
Managing deposit outflows while preserving asset growth capacity through HQLA stocks.
Dependency Balance
Strict oversight of Loan-to-Deposit (LDR) and Purchased Fund ratios to avoid volatility.

Dynamic GAP Strategy & IRR
Managing Interest Rate Risk (IRR) requires a granular time-bucket analysis of Rate Sensitive Assets (RSA) vs Rate Sensitive Liabilities (RSL).
Simulation Modeling
Forecasting balance sheet composition under varied rate shock scenarios (+/- 100bp, 200bp, 300bp).
Duration Analysis
Quantifying the sensitivity of fixed-rate investment economic value relative to equity capital shocks.
| Core Sensitivity Metric | 2026 Benchmark Target |
|---|---|
| RSA to RSL Ratio | 1:1 Strategic Neutral |
| GAP to Equity Sensitivity | Under 10% Violation |
| Volatility Coverage | Hedged vs Uncovered |
NII Sensitivity Analysis (Example)
Effect of 365-day cumulative rate shift on Net Interest Income.
Note: A 300 bps hike typically warrants a potential **>20% change** in interest income volatility for highly leveraged institutions.
ALCO Strategic Deployment
Falling Rates
Aggressively prune fixed-rate liabilities; accelerate acquisition of fixed-rate assets to lock in yields.
Rising Rates
Secure long-term fixed-rate liabilities; pivot toward variable-rate asset portfolios to ride the curve.
2026 ALM Readiness
Modern ALCOs must now integrate **LCR (Liquidity Coverage Ratio)** and **NSFR (Net Stable Funding Ratio)** into their daily dashboards, ensuring that profitability never comes at the cost of immediate survival.
CAIIB Paper 2 (BFM): ALM, Structural Liquidity & Duration Gap MCQs
Q1. A bank has Rate Sensitive Assets (RSA) of ₹42,000 Cr and Rate Sensitive Liabilities (RSL) of ₹35,000 Cr in the 1-year repricing bucket. If interest rates increase across the board by 100 bps (+1.00%), what is the impact on Net Interest Income (NII)?
Q2. Under RBI Structural Liquidity Statement (ALM) guidelines, what is the maximum permissible negative cumulative mismatch (as a % of outflows) in the 1-day, 2–7 days, 8–14 days, and 15–28 days buckets respectively?
Q3. If a bank has a positive Duration Gap (DA − (L/A) × DL > 0) and market interest rates rise by 150 bps, what happens to the Economic Value of Equity (EVE)?
