The European Commission has adopted temporary changes to the application of Basel III market-risk rules, delaying the full capital impact on EU banks for three years in response to slower implementation in other major financial jurisdictions.
The decision, announced on 4 June, adjusts the EU’s application of the Basel III market-risk framework, also known as the Fundamental Review of the Trading Book. The measures are due to apply from 1 January 2027 and run until the end of 2029, unless the European Parliament or the Council objects.
The Commission said the change is intended to preserve a level playing field for EU banks active in international capital markets. In practical terms, Brussels is seeking to avoid a situation in which European banks face higher capital charges on trading activities while competitors in the United States and the United Kingdom operate under delayed, softer or still unfinished versions of the same global standards.
Basel III was designed after the financial crisis to make banks more resilient by tightening the way they measure risks and hold capital against them. The market-risk component applies to banks’ trading books, where institutions hold financial instruments exposed to changes in market prices. These rules are meant to ensure that capital requirements more accurately reflect the risks carried by banks in trading operations.
The EU has already incorporated much of the final Basel III framework into its banking rulebook. However, the market-risk part has proved politically and commercially sensitive because of the international nature of trading activities. Large EU banks compete directly with US and UK institutions in capital markets, investment banking and market-making. If the EU applies the rules faster or more strictly than rival jurisdictions, European banks argue that they could be placed at a disadvantage.
That argument has now shaped the Commission’s decision. The temporary adjustment follows an earlier consultation on market-risk prudential requirements, in which Brussels sought views on how to apply the new rules while other major jurisdictions remained behind schedule. The draft delegated act proposed targeted amendments to offset part of the capital impact of the Fundamental Review of the Trading Book for three years.
The issue is not only technical. It sits inside a wider EU debate over competitiveness, financial stability and the role of banks in financing the bloc’s economic agenda. The Commission has linked the decision to its broader Savings and Investments Union project, which is intended to mobilise more private capital for European companies, infrastructure, defence, energy transition and technology investment.
The trade-off is clear. Stricter capital rules can make banks safer by forcing them to hold more capital against risky positions. But higher capital requirements can also reduce returns on some activities and may make European institutions less competitive if international rivals face lower requirements. The Commission is now attempting to balance those two objectives without formally abandoning its Basel commitments.
The decision also reflects uncertainty in Washington and London. The US has not finalised implementation of all Basel III rules, while the UK has adjusted its own timetable. The Bank of England’s Prudential Regulation Authority set out final Basel 3.1 rules earlier this year, with implementation from 1 January 2027, but international divergence remains a concern for EU policymakers.
Financial industry groups have pressed Brussels to avoid unilateral implementation that would raise costs for EU-based banks while foreign competitors remain under different regimes. The European Banking Federation warned during the consultation process that higher risk-weighted assets could reduce banks’ capacity to finance long-term investment. The sector has argued that this would conflict with EU objectives on competitiveness and capital-market development.
Public-interest groups have taken a different view. Finance Watch has warned that simplification and competitiveness should not become a route to weakening safeguards introduced after the financial crisis. That concern is likely to remain part of the debate as the delegated act comes under parliamentary and Council scrutiny.
The Commission’s measure is formally temporary. It does not remove the market-risk framework from EU law, but adjusts its effect for a three-year period while Brussels monitors international implementation. The political question is whether the delay remains an interim competitiveness measure or becomes part of a broader pattern of regulatory easing.
For EU banks, the decision provides more time and reduces the immediate pressure of higher market-risk capital requirements. For policymakers, it exposes a recurring difficulty in global financial regulation: rules agreed internationally do not always enter force at the same pace or with the same force across jurisdictions.
The outcome will matter beyond bank balance sheets. If the EU applies prudential rules more cautiously in order to protect competitiveness, it may help its banks compete in global capital markets. But if international coordination weakens further, the credibility of common post-crisis banking standards could become harder to maintain.
