ALCO Metrics: Liquidity, IRRBB, and Balance Sheet Management

#ALM

If there is a point where balance sheet management comes together in banking, it is the Asset Liability Committee (ALCO). It brings together treasury, risk, and finance to assess positioning across liquidity, funding, interest rate risk (IRRBB), and profitability, and to support decisions that shape the balance sheet. 

In this article, we’ll explore how ALCO metrics are structured, how they are used in practice to manage the balance sheet, and how they support decision-making under both stable and changing market conditions.

Through ALCO, institutions monitor how the balance sheet evolves and evaluate the actions needed to maintain alignment with strategy, risk appetite, and market conditions.

The Role of ALCO in Balance Sheet Management

ALCO operates as a decision-making forum where the balance sheet is assessed in an integrated manner. Apart from monitoring performance and risk, the objective is to evaluate whether the current positioning remains aligned with strategic targets and risk appetite.

Most ALCO discussions focus on confirming that the balance sheet evolves as expected, based on metrics related to volumes, pricing, and risk exposures. When deviations are identified, the discussion shifts toward understanding their drivers, assessing their impact, and determining whether adjustments are required.

This process relies on the ability to connect different dimensions of the balance sheet. Liquidity, funding, interest rate risk, and profitability are not independent elements; they interact continuously. Decisions in one area often have implications in others, which makes a structured and consistent framework essential.

 

The ALCO Metrics Framework

The ALCO metrics framework provides a structured view of the balance sheet. It is typically organized around a standard set of elements that allow institutions to assess current positioning, expected evolution, and risk exposure. The following sections outline the main metrics used in practice and how they contribute to this view.

1. Balance Sheet View

The starting point is the balance sheet itself. This includes the structure and evolution of assets and liabilities, new production compared with existing stock, and the pricing applied to both.

This view allows institutions to assess how margin is being generated and whether the balance sheet is evolving in line with expectations. Differences between expected and actual performance provide a basis for identifying areas that require attention.

2. Forward-Looking View

Beyond the current position, ALCO extends the analysis to the expected evolution under existing conditions. This includes the projected balance sheet, expected production, and implied market conditions.

The objective is to understand how the balance sheet develops without introducing additional management actions. This provides a reference path that supports the evaluation of whether the current trajectory is acceptable.

3.  Interest Rate Risk (IRRBB)

IRRBB metrics provide a view of how the balance sheet responds to changes in interest rates. These typically include sensitivities of net interest income (NII) and economic value (EVE), supported by a range of scenarios.

These metrics allow institutions to assess exposure relative to risk appetite and to evaluate the potential impact of interest rate movements on both earnings and value.

 Mirai ALM & Liquidity covers both NII and EVE sensitivity across a full range of regulatory and behavioural scenarios — giving ALCO the granular rate risk view needed to assess positioning against appetite and act before exposures crystallize.

4. Liquidity and Funding

Liquidity metrics, including LCR, NSFR, and liquidity buffers, provide a view of the institution’s ability to meet short- and long-term funding needs. Funding metrics complement this by focusing on issuance plans, maturity profiles, and regulatory requirements such as MREL or TLAC.

Together, these metrics define the institution’s funding structure and its resilience under stress conditions.

 Mirai ALM & Liquidity monitors LCR, NSFR, and liquidity buffers in real time, with integrated stress testing that allows ALCO to assess funding resilience under multiple scenarios simultaneously, not just at the point-in-time reporting date. 

5. ALCO Portfolio and Internal Pricing

The ALCO portfolio provides a direct lever for balance sheet management. Its analysis focuses on yield, composition, and concentration, supporting decisions on positioning and risk exposure.

Internal transfer pricing (FTP or TTII) defines how funding costs are allocated across the balance sheet. It plays a central role in aligning commercial activity with treasury and risk considerations.

Mirai FTP & Profitability embeds transfer pricing directly into the balance sheet management framework, making the margin and risk impact of commercial decisions visible to ALCO at the product and business line level, in the same environment as liquidity and IRRBB analytics. 

6. Foreign Exchange Exposure

Foreign exchange exposure may be included in ALCO when it is material to the balance sheet. The focus is on positions by currency and whether exposures are hedged or remain open, as open positions introduce additional risk and may require management actions.

 

From Metrics to Decision-Making

While the ALCO framework is built on metrics, its value lies in how these metrics are used to support decisions. This requires moving from individual indicators to a combined interpretation that reflects the full balance sheet.

For example, a change in funding strategy may affect liquidity ratios, interest rate exposure, and margin simultaneously. Similarly, pricing decisions in commercial activity can influence both profitability and risk metrics. 

ALCO provides the structure to assess these interactions. It supports the evaluation of trade-offs across different objectives, such as profitability, risk, and regulatory compliance. It also provides a basis for selecting and adjusting management actions, including hedging strategies, funding decisions, and portfolio adjustments.

 

ALCO Under Changing Market Conditions

Under stable conditions, the ALCO framework provides a consistent view of the balance sheet, while changes in market conditions shift the focus toward understanding potential outcomes under uncertainty. In this context, scenario analysis becomes more relevant, allowing institutions to assess how key metrics evolve under different assumptions, including changes in interest rates, liquidity conditions, and market dynamics.

The effectiveness of this analysis depends on working with up-to-date information, as delays in data or analysis can reduce the relevance of results and limit the ability to respond proactively. This increases the importance of processes and tools that support timely analysis and allow scenarios to be updated as conditions evolve.

 

The Importance of Integration in ALCO Processes

One of the main challenges in ALCO is the fragmentation of data and analysis across different functions. Treasury, risk, finance, and business units often rely on separate systems and processes, which can make it difficult to obtain a consistent view of the balance sheet.

This fragmentation affects both the preparation of ALCO materials and the ability to analyze new scenarios. When data needs to be reconciled manually or when models are not aligned, the process becomes slower and less flexible.

An integrated approach addresses this challenge by connecting data, models, and reporting within a single framework. This allows institutions to work with a consistent view of the balance sheet and to assess the impact of decisions across multiple dimensions. The Mirai is built around this principle — a single data model connecting treasury, ALM, risk, FTP, and finance so that every ALCO metric, from LCR to EVE to NII, draws from the same source and can be reconciled without manual intervention. 

 

Why ALCO Matters for Balance Sheet Management and Decision-Making

ALCO is where balance sheet decisions come together in banking. It brings metrics, scenarios, and perspectives from treasury, risk, and finance into a single process to support assessment of positioning and the definition of management actions.

The effectiveness of this process depends on how consistently information is structured and how clearly it supports decision-making. Metrics provide the foundation, but their value comes from how they are interpreted together and how they are used to assess trade-offs across liquidity, funding, interest rate risk, and profitability.

As market conditions evolve, the ability to work with timely and connected information becomes increasingly important. Institutions that can assess scenarios, understand cross-metric impacts, and evaluate management actions within a consistent framework are better positioned to manage their balance sheet effectively.

 

How Mirai Supports ALCO

Mirai addresses these challenges by bringing the full balance sheet management workflow into a single integrated environment. connecting ALM & Liquidity, FTP & Profitability, Regulatory Reporting, and Mirai AI through a shared, traceable data model. 

From data ingestion to modeling, forecasting, and reporting, all components are connected through a shared and traceable data model. This ensures consistency across treasury, ALM, risk, FTP, and finance, allowing all functions to work from the same information.

This integrated approach enables institutions to move beyond fragmented views and manual reconciliation. Metrics, scenarios, and models are aligned, which makes it easier to understand how decisions affect liquidity, interest rate risk, profitability, and regulatory constraints.

Scenario analysis can be performed more efficiently, with the ability to update assumptions and evaluate outcomes without rebuilding the analysis from scratch. This supports a more responsive ALCO process, particularly under changing market conditions.

By providing a unified view of the balance sheet, Mirai allows institutions to focus on assessing trade-offs and selecting appropriate management actions, rather than on data preparation and reconciliation.

FAQ: ALCO Metrics

  • What is ALCO in banking?
    ALCO (Asset Liability Committee) is a decision-making forum in banks that brings together treasury, risk, and finance to assess balance sheet positioning across liquidity, funding, interest rate risk, and profitability.

  • What metrics does ALCO monitor?
    ALCO typically monitors a core set of metrics covering the balance sheet structure, forward-looking projections, IRRBB sensitivities (NII and EVE), liquidity ratios (LCR, NSFR), funding plans (MREL, TLAC), the ALCO portfolio, internal transfer pricing (FTP), and foreign exchange exposure.

  • What is IRRBB, and why does ALCO track it?
    IRRBB (Interest Rate Risk in the Banking Book) measures how changes in interest rates affect a bank's net interest income and economic value. ALCO tracks IRRBB to assess exposure relative to risk appetite and take action before rate movements impact earnings or capital.

  • Why is data integration important for ALCO?
    When data sits in separate systems across treasury, risk, and finance, reconciling it manually slows down analysis and limits the ability to respond to changing conditions. An integrated framework gives ALCO a consistent, timely view of the balance sheet across all relevant metrics.
  • How does ALCO support decision-making under changing market conditions?
    ALCO uses scenario analysis to assess how key metrics —NII sensitivity, liquidity ratios, funding gaps— evolve under different interest rate and market assumptions. This helps institutions evaluate management actions before conditions deteriorate.
