The Basel 4 implementation date has been pushed back due to global uncertainty. This change is a result of ongoing discussions between regulators and industry stakeholders.
The original implementation date was set for 2023, but it's now unclear when the new rules will take effect. This delay is causing uncertainty for banks and financial institutions.
Regulators are taking a cautious approach to ensure that the new rules are implemented smoothly. They're working to address concerns and provide clarity on the requirements.
Basel IV Overview
Basel IV is a significant regulatory framework that will impact the European banking industry. It introduces stricter capital requirements, increasing the capital banks need to hold.
The new regulations will limit the reduction of capital due to leveraging internal model Risk-weighted Assets (RWA), which European banks rely on heavily. This will result in each European bank, on average, requiring an additional €120 million in capital.
Basel IV also introduces a 72.5% high output floor for RWA, reduces standardised risk weights for low-risk mortgage loans, and increases the leverage ratio for Global Systemically Important Banks (G-SIBS). This will compound capital requirements for European banks.
British banks alone will need to raise £50 billion in capital to meet Basel IV capital requirements. The CET1 capital ratio for European banks will decrease by 0.9%, and the return on equity will fall by 0.6%.
What Is Basel
The Basel Accords are a set of banking supervision regulations set by the Basel Committee on Banking Supervision (BCBS). The purpose of Basel is to ensure that financial institutions hold enough cash reserves to meet their financial obligations and survive unexpected losses in times of economic crisis.
Basel was created during the 1980s, providing banks with recommendations around regulations, focusing on capital, market, and operational risk. Some updates were made, which became known as Basel 2. However, after the collapse of Lehman Brothers and the financial disaster which followed, the BCBS agreed that the framework needed to be more robust.
The original Accord was updated to become Basel 3, introduced in 2010. Basel 3 includes reforms designed to provide increased safeguarding, better regulation, improved supervision, and more effective risk management within the banking sector.
Basel IV Impact on European Banking
Basel IV regulations will increase capital requirements for European banks, limiting the reduction of capital due to leveraging internal model Risk-weighted Assets (RWA).
European banks rely heavily on these internal models, and the new regulations will require each bank to hold an additional €120 million in capital on average. This is due to the proposed 72.5% high output floor for RWA.
British banks alone will need to raise £50 billion in capital to meet Basel IV capital requirements. The implementation of Basel IV and related CRD5 and CRR2 guidelines will bring significant changes to the European banking sector.
Banks will need to put their best foot forward to avoid unnecessary non-compliance penalties and sanctions. By leveraging advanced compliance tools, banks in Europe may be able to navigate the regulatory landscape with greater success.
The CET1 capital ratio for European banks will decrease by 0.9%, and the return on equity will fall by 0.6% due to the new regulations. Basel IV also introduces stricter disclosure requirements on reserves and other financial statistics.
Preparation and Timeline
The Basel 4 implementation date is a topic of much discussion among financial institutions. The UK and EU central banks and regulators are strongly supporting the BCBS timeline, with the US aiming for the January 2023 deadline.
However, financial institutions are concerned about their readiness for the final changes, especially considering the pandemic's impact on their profitability. A report by KPMG highlights how profitability was already a concern for many banks pre-COVID-19, which will now be exacerbated by low-interest rates and other challenges.
The European Commission has proposed a deferral of Basel IV implementation in the European Union by two years to 1 January 2025, with a transition period until 2032. This will make the immediate impact of Basel IV on lending to corporates less drastic, but the long-term impact remains the same.
New Timeline - Bank Support and Opposition
The new timeline for implementing Basel reforms has received strong support from UK and EU central banks and regulators, who want to stick to the BCBS timeline. They've seen the effectiveness of these reforms during the pandemic and are eager to move forward.
The US is also aiming for the January 2023 deadline, but final capital rules still need to be agreed upon. This is a key step in the implementation process.

Financial institutions, however, are concerned that the pandemic's impact on their profitability means they're still recovering and may not be ready for the final changes, even with the new deferred deadline. This is a valid concern, given the challenges they're facing.
A report by KPMG highlights the struggles of banks, noting that profitability was already a concern before the pandemic and will now be exacerbated by low-interest rates, non-performing loans, and other issues. This is a tough situation for banks to navigate.
EU banks have raised concerns with the BCBS that Basel 4 reforms create an uneven playing field, disadvantageing them compared to their US and global competitors. This is a critical issue that needs to be addressed.
A Different Journey to the Same Endgame
The European Commission proposed a deferral of Basel IV implementation in the European Union by two years to 1 January 2025.
This means that instead of the original deadline, banks will have more time to prepare for the changes. A transition period until 2032 will also be in place, during which banks can use lower risk weights when calculating risk-adjusted lending to non-rated large corporates.

The output floor, which limits banks' benefits from internal risk models, will be implemented gradually in 2025-30. This should make the immediate impact of Basel IV on lending to corporates less drastic, but the long-term impact is virtually the same as before.
The European Commission's proposal aims to create a more level playing field for European banks, which have raised concerns that Basel IV reforms disadvantage them against their US and global competitors.
According to an industry report, British banks alone will need to raise £50 billion in capital to meet Basel IV capital requirements.
Expert Insights and Background
The Basel 4 implementation date is a significant milestone for banks and financial institutions. The BCBS has developed an additional new chapter in the Basel Framework setting out bespoke treatment of cryptoasset exposures.
The capital and liquidity requirements for cryptoassets are substantial, and banks must consider these factors when deciding to acquire and deal in cryptoassets. Tokenized versions of traditional securities may not be attractive due to added capital and liquidity surcharges.
Banks will face significant capital costs when dealing with many cryptoasset types, which may act as a barrier to bank participation in these markets. The Standards reflect a cautious approach to bank cryptoasset exposures, imposing a capital requirement matching at least the absolute exposure value of the cryptoasset in many cases.
Expert Voices
The experts weigh in on the impact of Basel IV on banks and their customers. Johan Hansing, Chief Economist at The Swedish Bankers' Association, shares his views on the implementation of Basel IV.
Banks will likely face increased regulatory requirements due to the stricter capital adequacy rules under Basel IV. This could lead to reduced lending and a decrease in economic growth.
Johan Hansing highlights the importance of careful planning and implementation to minimize the negative effects of Basel IV on banks and their customers.
Antti Lemberg and Jonas Bjarke Jensen, Managing Economists at Copenhagen Economics, also share their insights on the likely impact of Basel IV on banks and their customers.
Background

Capital and liquidity requirements for cryptoassets are significant factors in a bank's decision to acquire and deal in cryptoassets.
Banks are deterred from holding tokenized versions of traditional securities if there are added capital and liquidity surcharges associated with them.
The Basel Committee on Banking Supervision (BCBS) has developed a bespoke treatment for cryptoasset exposures due to the novelty of the asset class and the additional risks associated with bank cryptoasset holdings.
The BCBS issued its finalized Standards in December 2022 and revised them in July 2024, setting out further requirements for banks to benefit from a preferential treatment for stablecoin exposures.
Compliance with the Standards would be subject to supervisory responses, including the imposition of capital add-ons, provisions, and internal limits.
Banks dealing in many cryptoasset types will come with significant capital costs, acting as a barrier to bank participation in these cryptoasset markets.
A cautious approach is reflected in the Standards, with some cryptoassets and cryptocurrencies imposing a capital requirement matching at least the absolute exposure value of the cryptoasset.
Implementation Challenges
Implementing Basel 4 will be a significant challenge for banks, requiring significant investments in technology and human resources.
Banks will need to upgrade their risk management systems to accommodate the new standards, which will be a costly and time-consuming process.
According to the article, Basel 4 will require banks to hold more capital against risk-weighted assets, which will increase their regulatory capital requirements.
This will put pressure on banks to reduce their risk-weighted assets or increase their capital buffers, which will be a difficult balancing act.
The new standards will also require banks to conduct more frequent and detailed stress tests, which will be a significant challenge for their risk management teams.
Banks will need to invest in new technology and tools to support these stress tests, which will require significant upfront costs.
The implementation timeline for Basel 4 is ambitious, with many banks struggling to meet the deadline.
