The European Central Bank's push to simplify banking rules has raised concerns about capital requirements.

Germany's proposal for "greatly simplifying bank capital structures" has become the most controversial topic in the European Central Bank's efforts to streamline banking regulations. Market concerns that the proposal may lead to new capital requirements for some banks, while also weakening the uniformity of banking supervision within the eurozone. According to sources familiar with the work of the European Central Bank President's group, although the concept of "simplifying bank capital requirements" has wide support, there is still no consensus on the specific path to achieving this goal.
