The Asset Liability Committee, universally known as ALCO, is the governance body inside a bank or financial institution responsible for managing the balance between assets and liabilities. Its decisions determine how much interest rate risk, liquidity risk, and funding risk the institution carries at any given time. Understanding ALCO's role is essential for anyone analyzing banks as investments or studying how financial institutions operate.

## What Is an Asset Liability Committee (ALCO)?

ALCO is a senior management committee, typically chaired by the CFO or CEO, that oversees the structure of a bank's balance sheet. Its mandate is to ensure the institution can meet its obligations, earn a stable net interest margin, and stay within regulatory risk limits.

*The five primary mandates that define ALCO's scope across a bank's balance sheet.*

ALCO operates at the intersection of risk management, treasury, and strategic finance. It doesn't manage individual loans or investments, it sets the policy framework within which those decisions are made.

**Core responsibilities**:
- Managing interest rate risk (how changes in rates affect earnings and economic value)
- Ensuring adequate liquidity (the ability to fund operations and meet withdrawals)
- Optimising the net interest margin (NIM), the spread between what the bank earns on assets and pays on liabilities
- Setting transfer pricing for internal funds
- Stress testing the balance sheet under adverse scenarios

## ALCO Structure and Membership

ALCO membership typically includes:

| Role | Responsibility in ALCO |
|---|---|
| CFO (Chair) | Overall balance sheet strategy |
| Chief Risk Officer | Risk appetite and limit oversight |
| Treasurer | Funding, liquidity, and markets execution |
| Chief Credit Officer | Loan portfolio risk |
| Head of Finance | Reporting and forecasting |
| Business line heads | Deposit and lending volume input |

ALCO meets monthly (or more frequently during stress periods) and reviews a standardised pack of reports covering rate sensitivity, liquidity ratios, funding concentrations, and gap analyses.

## Key Metrics ALCO Monitors

### Net Interest Margin (NIM)

**NIM = (Interest Income − Interest Expense) / Average Earning Assets**

NIM is the bank's primary revenue driver. ALCO monitors how shifts in rates affect NIM, for example, a bank with mostly floating-rate loans and fixed-rate deposits benefits when rates rise; one with long fixed-rate mortgages funded by short-term deposits faces compression.

### Duration Gap

Duration gap measures the difference between the average duration of assets and liabilities. A positive gap means assets reprice slower than liabilities, the bank is "liability-sensitive" and suffers when rates rise. A negative gap means assets reprice faster, the bank is "asset-sensitive" and benefits from rising rates.

ALCO targets a duration gap close to zero (immunised against rate movements) or deliberately positions for a view on rates.

### Liquidity Coverage Ratio (LCR)

Under Basel III, banks must hold enough high-quality liquid assets (HQLA) to cover 30 days of net cash outflows in a stress scenario. ALCO ensures the LCR stays above the 100% regulatory minimum.

**LCR = HQLA / Net Cash Outflows over 30 days ≥ 100%**

### Net Stable Funding Ratio (NSFR)

Complements the LCR by ensuring long-term assets are funded by stable, long-term funding sources. Requires NSFR ≥ 100%.

### Earnings at Risk (EaR) and Economic Value of Equity (EVE)

- **EaR**: How much NIM would fall in a +/-200 basis point rate shock over 12 months
- **EVE**: How much the economic value of the balance sheet would change in the same shock

Regulators use EVE to assess capital adequacy under rate stress. ALCO sets internal limits (e.g., EVE cannot decline more than 15% in a +200bp shock).

## Interest Rate Risk Management

ALCO uses several tools to manage interest rate risk:

**Repricing gap analysis**: Buckets assets and liabilities by when they reprice (overnight, 1–3 months, 3–12 months, 1–5 years, 5+ years). A mismatch (gap) in any bucket creates rate sensitivity.

**Interest rate swaps**: ALCO can hedge fixed-rate loan exposure by entering into swaps that convert fixed receipts to floating, or vice versa. This is covered in depth in our guide on [notional value](/blog/notional-value).

**Adjusting product mix**: ALCO may direct commercial teams to originate more floating-rate loans or to attract longer-term fixed deposits if the positioning requires it.

## ALCO and Liquidity Management

Liquidity risk, the risk that a bank cannot fund itself when needed, is ALCO's most critical near-term concern. The 2023 Silicon Valley Bank collapse illustrated what happens when ALCO fails: SVB's balance sheet was heavily positioned in long-duration fixed-rate bonds funded by unstable uninsured deposits. A rate shock caused unrealised losses; a bank run crystallised them.

ALCO manages liquidity through:
- **Diversified funding sources**: Core deposits, wholesale funding, repo markets, FHLB advances
- **Liquidity buffers**: Unencumbered HQLA that can be sold or pledged immediately
- **Contingency funding plan (CFP)**: Pre-approved playbook for stress scenarios
- **Intraday liquidity monitoring**: Real-time tracking of settlement obligations

## ALCO in Practice: A Bank's Monthly Cycle

1. **Treasury** prepares rate sensitivity analysis, liquidity metrics, and funding report
2. **Risk** provides EVE and EaR estimates under base and stress scenarios
3. **Business lines** report deposit flows, loan volumes, and pipeline
4. **ALCO** reviews the consolidated picture against policy limits
5. **Decisions made**: Adjust hedging positions, reprice deposits, access term funding markets, or revise internal transfer pricing
6. **Minutes approved** and escalated to the Board Risk Committee if limits are breached

## Why ALCO Matters for Bank Investors

When analysing banks as investments, ALCO disclosures reveal the risk embedded in the balance sheet:

- **Rising rate sensitivity**: An asset-sensitive bank (positive duration gap) benefits from rate hikes; a liability-sensitive bank is hurt
- **NIM guidance**: ALCO's hedging decisions determine future NIM trajectory
- **Liquidity profile**: Concentration of uninsured deposits, reliance on wholesale funding, and HQLA buffer size are all ALCO outputs disclosed in annual reports
- **Derivative use**: Swap hedges on the balance sheet reduce NIM volatility but cap upside in favourable rate environments

For deeper analysis of bank balance sheet metrics, see our guides on [leverage and gearing ratios](/blog/leverage-gearing-ratio) and [weighted average maturity](/blog/weighted-average-maturity).

## Conclusion

The Asset Liability Committee is the central nervous system of a bank's risk management infrastructure. It balances the inherent tension between earning higher returns (which requires taking rate and liquidity risk) and maintaining safety (which requires limiting those risks). For investors, understanding how well a bank's ALCO is positioned, and how transparently they disclose it, is one of the most important inputs to any bank equity analysis.
