ICAAP models : Model inventory and multi-year model validation plan

FOCUS ON: Case studies,

The client is one of the largest financial institutions in France. It offers its clients a wide range of products and services: savings, investment, treasury, financing, insurance and investment solutions.

THE CHALLENGE

Following an ECB on-site inspection dedicated on the Group’s ICAAP, many findings pointed out the necessary areas of improvement of ICAAP models but also the lack of independent validation of key Pillar 2 models. In addition, the ECB concluded that the bank did not have sufficient quantitative capabilities or resources to properly conduct independent validations of these models. To address these shortcomings and as a first step to an effective Model Risk Management Framework, the client decided to develop an inventory of all ICAAP models in order to score them and define the key priorities in terms model validation for the following years.

APPROACH AND SOLUTION

Avantage Reply supported the bank in the implementation an action plan to address the shortcomings of the ICAAP validation process. This was done through conducting a number of methodological workshops in order to:

Define what could be considered as an ICAAP model to identify all internal models that needed to be included in the new independent validation scope
Design a granular ICAAP model inventory
Build a model scorecard which could be used to score and rank the models considering the key steps of the model lifecycle
Establish a multi-year independent validation program
Draft a set model and application inventory procedures to close the ECB’s key findings regarding ICAAP model independent validation

RESULTS AND BENEFITS

At the conclusion of the project, the key benefits and results for the bank were:

The concept of “ICAAP model” was defined and included in the validation process
The scope of ICAAP models to be reviewed by the independent validation function was defined, including economic capital models, stress testing models, ALM models and risk models
A model inventory was established and enriched with a scorecard to rank and tier all models in the inventory
The model validation process was reinforced with the creation of a multi-year independent validation programme for all ICAAP models

Case Study

IRRBB Audit Follow-Up

Avantage Reply assisted the internal audit department of a leading Private Bank in the Eurozone, a less significant institution (LSI) that is part of an international group, in the final steps of an internal review of the Interest Rate Risk in the Banking Book (IRRBB) framework. In summer 2019, Avantage Reply assisted the client following an audit by the national regulator regarding IRRBB and established an action plan to deal with the shortcomings identified during the regulator’s on-site inspection. The goal was to identify the status of these shortcomings and possible mitigations in order to achieve full compliance with regulatory requirements.

Case Study

Risk Analysis for the introduction of new lending products

The client, a public lending bank, wanted to introduce two new products to its portfolio and needed to conduct a risk assessment in order to determine the bank’s capital needs for these new products. The main problem was that the client had no internal data to support such an assessment. Using historic statistical data, AR provided the client with a model that allowed to assess the risks associated with these products and determine the capital needs for these products.
