The European Commission is actively considering three main options regarding changes to trading book capital requirements for banks. This move comes as part of the EU's initiative to expedite the review of European bank competitiveness. The urgency for this review has been heightened by demands from the region's three largest economies, which are seeking to ensure that their banks can effectively compete with Wall Street counterparts. The EU's commitment to this review reflects a growing concern over the competitive threat posed by U.S. financial institutions.
