The Basel Committee has proposed that globally systemically important banks (G-SIBs) set aside equity worth one to 2.5 per cent of their risk-weighted assets, depending on their size and complexity, to make them safer.
About 28 such banks would set aside the surcharge at first, the committee said. It will consult until 26 August.
The Financial Stability Board also began consulting on its proposals to wind up struggling systemically important banks.
These cover living wills and bail-in plans, and will consult until 2 September.
