A recap of the Basel IV regulation and its timeline

In this article, we wanted to give a short recap on the background of Basel IV, where it comes from, and how it all started. Basel IV, the finalization of Basel III, will be a game-changer when it comes to access to financing.

This article is an intro article in a series of Basel and CRD6/CRR3-related articles, stay tuned for more.

The Background

The Basel Committee on Banking Supervision (BCBS) is the primary global standard-setter for the prudential regulation of banks, based in Basel, Switzerland. Committee members include central banks and other banking regulators from around the world. Their main target is to improve supervisory understanding and the quality of banking supervision worldwide. The Basel Committee on Banking Supervision (BCBS) sets the Basel Framework, and they have issued a round of regulations in recent years. 

Basel Timeline

Basel Timeline

Basel I, followed by II, III, and IV, reforms the Basel Accords. In the beginning, capital adequacy was the main focus of the Committee. Its purpose was to strengthen the international banking system’s stability and remove a source of competitive inequality arising from differences in national capital requirements. Basel I was introduced in 1988, requiring banks to hold capital of at least 8% of their risk-weighted assets. In 1999 Basel Committee issued a proposal for a new capital adequacy framework to replace the first one, and finally, after intensive preparation, Basel II was introduced in 2004.

Basel IV and liquidity risk management

The banking sector entered the financial crisis in 2007 with too much leverage and inadequate liquidity buffers. Additionally, poor governance and risk management were seen in the mispricing of credit and liquidity risks and excess credit growth. Responding to these risk factors, in 2009, the Basel Committee issued a package of documents to strengthen the Basel II capital framework. In 2010 the Group of Governors and Heads of Supervision (GHOS) announced higher global minimum capital standards for commercial banks. This followed an agreement reached in July regarding the overall design of the capital and liquidity reform package, now referred to as Basel III. The Committee issued the proposed standards in mid-December 2010 (and have been subsequently revised). The enhanced Basel framework revises and strengthens the three pillars, and most reforms are being phased in between 2013 and 2019. Basel III was at the beginning scheduled to begin implementation by 2015. Still, the deadline has been pushed back several times, and its current deadline is Jan. 1, 2023, although some provisions are already in effect in some countries.

Basel IV/3.1

Even though Basel III wasn’t fully implemented yet, the BCBS continued to adjust it. In 2017, the Basel Committee agreed on fundamental changes for Basel III. The changes became so vast that they were seen as a completely new framework, informally called Basel IV. It is also referred to as Basel 3.1. Basel IV is the final reform of Basel III, and the purpose of Basel IV was to strengthen the banking sector against future crises. Basel Committee’s analysis highlighted that banks’ calculation of their risk-weighted assets varied enormously. Basel IV aims to restore credibility in those calculations by constraining banks’ use of internal risk models. Advanced internal risk models give banks the most freedom to estimate their credit risk, often yielding a much lower risk weighted assets (RWA) than the regulator’s standard model. Under Basel IV, banks couldn’t longer use these typically more sophisticated and complicated internal rating-based (IRB) models for large corporates with a turnover of at least 500 million EUR. Instead, Basel IV introduced a so-called output floor, which prevents a bank’s own internal measurement of its RWA exposure from yielding less than 72.5% of the standardized approach.

Basel IV is split into two pieces.  The first package includes:

•            Fundamental Review of the Trading Book (FRTB)

•            Counterparty Credit Risk

•            Net Stable Funding Ratio (NSFR)

•            Leverage ratio

•            Large exposure

•            Market risk

•            Intermediate EU parent undertaking

The second package covers:

  • Credit risk – Standardized Approach to Credit Risk (SA CR)
  • Credit risk – Internal models
  • Credit risk – mitigation techniques
  • Market risk
  • Operational risk
  • Output floors
  • Sustainability
  • Credit Valuation Adjustment (CVA) risk

Basel IV timeline & implementation date

Basel IV was intended to begin implementation on Jan. 1, 2022, and it was supposed to be fully implemented by January 2025. The first package (described above) was originally supposed to go into effect in January 2023. Then the second package was supposed to follow and go into effect in January 2025. Now the situation with Basel IV is a bit uncertain. Due to the global pandemic, the start date/deadline has now been pushed back to Jan. 1, 2023. Based on recent history, it is still possible that the deadline will be extended and that some provisions may be further modified before they go into effect.

CRD6/CRR3 legislation published in the EU

As mentioned at the beginning of this article, Basel is an international standard. European Union wanted to go further at a faster pace. And as a result, on Oct. 27, 2021, the European Commission published its 2021 Banking Package, called CRD6/CRR3. The package’s purpose is to strengthen banks’ resilience and prepare banks for the future.

There are three parts to the package:

  • Implementing the final Basel reforms (Basel 4/ Basel 3.1)
  • Sustainability – contributing to the green transition
  • Stronger supervision – ensuring sound management of EU banks and protecting financial stability

Our next blog post will discuss CRD6/CRR3 legislation in more detail, stay tuned!
