) -- Large-cap banks as a group saw their loan portfolios shrink in the second quarter, while small- and mid-sized banks both stepped up lending, according to a report published Tuesday by Keefe, Bruyette & Woods (KBW).

Large cap banks saw loans shrink in every loan category except for commercial and industrial loans -- essentially loans to non-real estate companies.

Large cap banks account for 90% of loans in the banking industry, according to KBW's report.
