Banking and commerce: a liquidity approach

This paper looks at the advantages and disadvantages of mixing banking and commerce, using the "liquidity" approach to financial intermediation. Adding a commercial firm makes it easier for a bank to dispose of assets seized in a loan default. This "internal market" increases the liquidity of such assets and improves the bank's ability to perform financial intermediation. More generally, owning a commercial firm may act either as a substitute or a complement to commercial lending. In some cases, a bank will voluntarily refrain from making loans, choosing to become a nonbank bank in an unregulated environment.
