Prudential Authority proposes enhanced ILAAP for banks

The South African Reserve Bank's Prudential Authority has proposed a new directive outlining requirements for the Internal Liquidity Adequacy Assessment Process (ILAAP) for banks. This aims to ensure robust liquidity risk management through a dual framework, integrating banks' own risk assessment with regulatory requirements.

A dual framework for robust liquidity

The proposed directive from the Prudential Authority (PA) establishes a comprehensive Internal Liquidity Adequacy Assessment Process (ILAAP) for banks, controlling companies, and branches of foreign institutions.

Guided by the Basel Committee's Principles for Sound Liquidity Risk Management and Supervision, the ILAAP integrates a bank's own risk assessment with regulatory liquidity requirements, ensuring a robust evaluation of liquidity adequacy.

This dual framework is underpinned by strong governance, rigorous stress testing, and detailed documentation, and is designed to integrate seamlessly with the Internal Capital Adequacy Assessment Process (ICAAP) and recovery planning.

The ILAAP's objective is to ensure adequate liquidity resources, a prudent funding profile, and effective control of liquidity and funding risks across all scenarios.

Banks must submit their ILAAP, along with a signed Liquidity Adequacy Statement (LAS), to the PA annually, demonstrating compliance.

Empowering boards, testing limits

The directive places ultimate accountability for the ILAAP squarely with the board of directors, requiring annual approval of the ILAAP and the signing of a Liquidity Adequacy Statement (LAS).

Boards must embed the ILAAP within their risk management and strategic decision-making frameworks, conducting annual effectiveness reviews.

The ILAAP is designed to underpin strategic planning, ensuring liquidity and funding considerations are central to management culture.

A critical component is robust stress testing, mandated by Regulation 39(5)(i)(iii), which requires banks to evaluate liquidity adequacy under severe yet plausible forward-looking scenarios.

These tests must assess impacts on cash flows, profitability, and funding, while also integrating with ICAAP to capture liquidity-capital interactions.

Furthermore, banks must undertake annual reverse stress testing, challenging ILAAP assumptions and necessitating practical mitigation measures for identified vulnerabilities.

Enhanced oversight, deeper integration

This proposed directive marks a significant step towards strengthening liquidity risk management within the South African banking sector, aligning local practices more closely with international Basel standards.

By mandating a dual framework and explicit board accountability, the Prudential Authority aims to embed liquidity considerations more deeply into banks' strategic and operational decision-making.

The enhanced framework, while increasing compliance burden, is crucial for fostering greater financial resilience and supervisory effectiveness.
