Move to tighten rules on bank capital buffers

Global banking regulators have outlined how they will crack down on wide variations in the way big banks calculate the size of their capital buffers.

Regulators on the Basel Committee, which sets rules for the sector worldwide, worry such variations undermine investor confidence in the capital ratios, a key measure of financial health.

The committee yesterday outlined policy measures and fixes it will consult on over the coming year, reflecting a view that there is no single cause or solution to the problem.
