Financial Times reports that Wall Street banks are lobbying US regulators to ease Basel capital rules further. The outlets describe this effort as continuing pressure even after banks have secured what the Financial Times characterizes as their largest lobbying win since the financial crisis. Under the Basel framework, capital requirements are intended to set risk-based minimum buffers for banks, affecting how much capital firms must hold against assets. The reporting indicates banks are seeking additional adjustments beyond those already agreed or underway, arguing for changes that would potentially reduce constraints and increase flexibility in capital planning and lending. The effort involves bank industry participants urging regulators to revisit or relax specific Basel-related requirements in the US implementation. The articles do not provide detailed figures in the provided excerpts, but the overall theme is that lobbying remains active and aimed at additional regulatory relief. The coverage frames the push as part of a broader debate over the balance between maintaining financial stability through capital buffers and limiting the operational and balance-sheet impact of tighter capital requirements.
