The rules give banks until 2015 to meet liquidity obligations and until 2018 to meet capital ratio requirements.

The committee said that the liquidity requirements could be subject to change if they generate “unintended consequences” during the next few years, seen as an “observation period”.
PricewaterhouseCoopers’ Richard Barfield says that the liquidity rules will be tougher to comply with: “Competition for the limited supply of [liquid] retail deposits and medium-term funding will be fierce,” he said.
The publication ends months of uncertainty about the details of regulatory changes to the world’s banking system.
