Balance sheets carry the memory of every strategic decision taken by a financial institution. Funding structures and refinancing choices quietly shape how an institution reacts once market conditions begin to shift. Long before stress materializes, vulnerabilities are already embedded within the balance sheet itself.
This article is about how the ILAAP and ICAAP frameworks are becoming more connected to stress testing, balance-sheet forecasting, and simulation environments designed to support resilient balance-sheet management under changing market conditions.

Over the last few years, prudential management has moved much closer to the operational reality of financial institutions. Supervisory discussions now focus far more on how vulnerabilities are understood, how assumptions evolve under pressure, and how management actions would operate once funding conditions begin deteriorating. Annual exercises and static documentation remain part of the framework, although they no longer define the framework by themselves.
This evolution has also exposed the operational strain created by fragmented infrastructures and disconnected analytical processes. Large-scale stress exercises require consistency across forecasting assumptions and reporting methodologies while adapting simulations to changing market conditions. As prudential exercises become more simulation-driven, analytical environments capable of connecting liquidity management with broader balance-sheet decision-making are becoming more operationally relevant.
ILAAP and ICAAP Beyond Documentation
Historically, many institutions approached ILAAP and ICAAP as supervisory requirements centered around documentation cycles and periodic reporting exercises. Liquidity and capital assessments often remained separated from the way the balance sheet was managed on a day-to-day basis, even though changing market conditions and evolving supervisory expectations now require a much closer connection between prudential frameworks and operational balance-sheet management.
This closer connection is changing the role these frameworks play within the institution itself. ILAAP and ICAAP now influence areas such as:
-
Funding structure evaluation
-
Refinancing dependency analysis
-
Balance-sheet forecasting under stress
-
Management actions linked to deteriorating conditions
-
Liquidity and capital projections across different planning horizons
Prudential management is gradually becoming part of the broader balance-sheet conversation rather than remaining isolated within periodic supervisory exercises.
Supervisory expectations now extend directly into how resilience is evaluated under stress. The discussion increasingly focuses on:
-
How liquidity and capital conditions evolve as market environments deteriorate
-
How vulnerabilities emerge across the balance sheet
-
How management actions affect resilience through time
-
How assumptions remain consistent across interconnected exercises
While the operational dimension of many prudential exercises currently focuses more heavily on ILAAP, broader methodological foundations also extend across ICAAP. Stress scenarios and management assumptions often operate through connected frameworks where liquidity and capital assessments rely on shared balance-sheet projections.
This evolution becomes particularly visible during stress-testing exercises. Liquidity pressures can rapidly affect funding capacity, refinancing conditions and capital positions, especially when market conditions deteriorate across multiple dimensions simultaneously. Analytical environments capable of connecting liquidity and capital perspectives inside a consistent balance-sheet view are therefore becoming more important within prudential management processes.

Stress Testing as a Balance-Sheet Exercise
Stress testing now sits much closer to the center of prudential management than it did only a few years ago. Modern exercises project how the balance sheet evolves under stressed conditions while evaluating how funding pressures and capital vulnerabilities propagate across the organization.
The exercise usually begins with balance-sheet forecasting based on business plans, refinancing structures, and expected funding evolution. Stress scenarios are then calibrated around the institution’s most relevant vulnerabilities.
These scenarios may include:
-
Institution-specific liquidity events
-
Systemic market disruptions
-
Combined funding and market stress scenarios
-
Reverse stress-testing exercises designed to identify survival limits
Stress exercises also evaluate changing customer behavior, refinancing restrictions and collateral deterioration affecting the balance sheet under pressure. The analysis extends beyond stressed ratios and focuses more heavily on how vulnerabilities evolve through time and how management decisions affect resilience once assumptions stop behaving as expected.
Stress testing also plays an important role in connecting prudential exercises with strategic balance-sheet management. Forecasting exercises require institutions to evaluate how lending activity, funding structures and liquidity buffers evolve under different scenarios while preserving coherence between planning assumptions and prudential projections.
This dynamic becomes especially relevant under severe but plausible stress environments where multiple vulnerabilities interact simultaneously. Funding outflows may accelerate while refinancing access deteriorates and market liquidity conditions tighten. Under these conditions, management actions cannot be evaluated independently of the broader balance sheet.
Supervisory expectations around stress scenarios have also evolved. Historical crises continue providing valuable reference points, although current exercises are expected to reflect changing funding conditions and institution-specific vulnerabilities affecting the balance sheet.

How to Align Your Prudential Framework with SREP Expectations
Why Integrated Simulation Matters
The operational complexity surrounding prudential exercises has increased substantially over the last few years. Many institutions still rely on fragmented infrastructures distributed across treasury, finance, planning and risk functions, where forecasting models and prudential reporting exercises are managed through separate systems requiring extensive manual reconciliation before results can be consolidated into a coherent supervisory view.
Under large-scale stress exercises involving multiple scenarios and evolving assumptions, consistency must be preserved across areas such as:
-
Forecasting assumptions
-
Management actions
-
Stress-testing methodologies
-
Prudential reporting processes
-
Balance-sheet projections across different planning horizons
This operational pressure is one of the reasons integrated analytical environments are becoming more relevant within modern prudential frameworks. Shared balance-sheet representations and connected simulation methodologies help institutions evaluate stress impacts through a more consistent operational framework tied directly to the balance sheet itself.
These environments also support a broader understanding of how vulnerabilities interact under stress, including:
-
Liquidity pressures affecting funding conditions
-
Refinancing constraints under deteriorating markets
-
Behavioral changes affecting deposit stability
-
Collateral deterioration under stressed environments
-
Management actions interacting across the balance sheet
This is where Mirai becomes operationally relevant within the prudential framework.
How Integrated Analytical Environments Connect Prudential Processes
Mirai ALM & Liquidity supports institutions through an integrated analytical environment capable of connecting liquidity management, stress testing, forecasting, and supervisory processes within a shared balance-sheet framework. This type of environment helps preserve consistency across evolving prudential exercises while reducing reconciliation complexity between functions.
Behavioral Assumptions and Funding Vulnerabilities
One of the most difficult aspects of modern prudential management involves the treatment of behavioral assumptions.
Contractual maturities rarely provide a sufficient understanding of resilience under stressed conditions. Deposits may become unstable. Refinancing capacity can deteriorate rapidly. Customer behavior can shift much faster than initially expected.
For this reason, modern ILAAP and ICAAP frameworks depend heavily on behavioral modeling capabilities capable of simulating changing funding conditions across different stress environments.
This includes evaluating:
-
Deposit stability under stress
-
Funding concentration risks
-
Refinancing dependencies
-
Collateral availability
-
Liquidity buffer consumption
-
Restrictions affecting market access
These exercises help institutions understand how vulnerabilities propagate across the balance sheet rather than relying exclusively on static contractual assumptions.
Behavioral assumptions also influence the credibility of the broader prudential framework. Stress scenarios and management actions remain closely connected to the institution’s ability to justify how customers, counterparties and funding providers would realistically behave under deteriorating market conditions.
This broader evolution also explains why supervisory discussions now focus much more heavily on operational realism. Credible stress assumptions and executable management actions now sit much closer to the center of prudential discussions.
The Mirai Treasury solutions support treasury and ALM teams in modeling these behavioral dynamics within a connected analytical environment. For a broader look at how institutions approach liquidity management amid uncertainty, see Liquidity Management in Uncertain Times: Key Strategies for Banks.
The Future of Prudential Management in the Balance Sheet
Prudential management is gradually moving toward more connected operating models where stress testing, forecasting and balance-sheet management function through shared analytical environments tied directly to the institution’s broader decision-making processes.
This evolution also reflects a broader change in how resilience itself is understood. Balance-sheet resilience depends heavily on understanding how vulnerabilities emerge, how assumptions evolve under stress, and how management decisions affect liquidity and capital conditions through time.
Stress testing now functions as one of the main connecting mechanisms between prudential management and strategic balance-sheet decision-making. Forecasting exercises, behavioral assumptions, and management actions converge within simulation environments designed to support a more coherent understanding of resilience under changing market conditions.
Prudential frameworks are therefore becoming more closely connected to the institution’s broader operational reality. Assumptions evolve alongside the balance sheet, while stress scenarios and management actions remain tied to changing funding conditions and balance-sheet dynamics.
That perspective now sits at the center of modern ILAAP and ICAAP frameworks. The objective is to maintain a living understanding of how the balance sheet behaves under pressure and how the institution would respond once conditions begin deteriorating.
Towards More Connected Prudential Frameworks
The evolution described across these sections reflects a structural shift in how financial institutions approach ILAAP and ICAAP. What began as documentation-driven compliance exercises is becoming an ongoing analytical capability—one where stress testing, behavioral assumptions, forecasting, and management actions are connected within a shared operational framework.
For institutions evaluating how to align their prudential infrastructure with these expectations, platforms such as Mirai ALM & Liquidity are designed to operate within governed environments where access to data, models, and regulatory frameworks is controlled and auditable. This supports not only the production of analysis but also its consistency, traceability, and alignment with internal policies and supervisory expectations.

FAQs: ILAAP, ICAAP, and Integrated Prudential Management
-
What is the difference between ILAAP and ICAAP?
ILAAP (Internal Liquidity Adequacy Assessment Process) evaluates whether a financial institution holds adequate liquidity buffers and manages funding risk appropriately. ICAAP (Internal Capital Adequacy Assessment Process) focuses on capital adequacy and whether the institution holds sufficient capital to cover its material risks. Both frameworks have evolved beyond standalone assessments into interconnected prudential processes connected to balance-sheet forecasting and stress testing.
-
Why are ILAAP and ICAAP no longer purely documentation exercises?
Supervisory expectations, particularly under the SREP (Supervisory Review and Evaluation Process), now focus on how institutions demonstrate resilience under stress—not just whether documentation is in order. This means stress scenarios, behavioral assumptions, and management actions need to be operationally credible, consistent across exercises, and connected to the institution's actual balance-sheet position.
-
What is the role of stress testing in ILAAP and ICAAP?
Stress testing is central to both frameworks. Modern exercises project how the balance sheet evolves under stressed conditions, evaluate funding vulnerabilities and capital impacts, and assess how management actions would realistically affect resilience. This includes idiosyncratic events, systemic disruptions, combined stress scenarios, and reverse stress testing to identify survival limits.
-
What are behavioral assumptions in a prudential context?
Behavioral assumptions describe how customers, counterparties, and funding providers are expected to act under stressed conditions. This includes deposit outflow rates, refinancing capacity under deteriorating markets, collateral haircuts, and changes in market access. These assumptions directly affect the credibility of liquidity and capital projections, and supervisors increasingly scrutinize whether they reflect realistic institution-specific behavior.
-
Why does fragmented infrastructure create problems for ILAAP and ICAAP?
When treasury, finance, planning, and risk functions operate on separate systems, stress-testing and forecasting exercises require extensive manual reconciliation before results can be presented coherently. This increases the risk of inconsistent assumptions, reduces the institution's ability to run multiple scenarios quickly, and makes it harder to maintain a live understanding of how the balance sheet behaves under pressure.
-
What is integrated simulation in the context of prudential management
Integrated simulation refers to analytical environments that connect liquidity management, stress testing, balance-sheet forecasting, and supervisory reporting within a shared framework. This allows institutions to model the interaction between funding vulnerabilities, behavioral changes, and management actions in a consistent and auditable way, supporting both internal decision-making and supervisory credibility.
