Still, Valladares said the changes are a major milestone — one that she expects banks will fight strenuously.

“This is the biggest news to come out of the Basel committee, because whatever they propose — whether it’s a floor, whether it’s making changes in formulae, whether it’s demanding that banks be more transparent about how they come up with risk weighted assessments — there will be a big battle, because banks are really going to push back,” Valladares said.
