Reuters reported, citing sources familiar with the matter, U.S. regulators are sending some of the largest banks verbal warnings that enforcement actions will be taken against them if they don’t improve on their ability to identify risks.

Reuters noted that the banks that received the warnings are among the largest in the world, but the sources declined to name individual firms because the enforcement actions are not public, Reuters said.
