While the answer to this question is truly impossible to answer if you are looking beyond the individual loan level, we can make a few observations that may offer some insight into where opportunities may still lie. Specifically, here is recent data from the FDIC showing the asset composition of US Commercial Banks and Savings Institutions:
($Tn) 2005 2008 2015
Real Estate Loans 4.00 4.80 4.20
C&I Loans 1.05 1.50 1.75
Loans to Individuals .93 1.08 1.40
Other Loans .16 .26 .60
Securities 1.90 2.00 3.30
Cash & due from Depository Inst .42 1.00 2.00
Fed Funds & Reverse Repos .45 .73 .37
Trading Account assets .53 .95 .66
Totals (not sum of above) 10.70 13.50 15.80
Bank assets were essentially flat from 2008-2012, which was a major problem for policy makers and thus QE4. While bank assets have increased fairly aggressively, it is interesting to note that the increase is entirely in securities held and an increase in cash - results of QE4. C&I loans (primarily to larger corporate borrowers), loans to individuals (credit cards, auto loans, etc. - things that can easily be securitized in the ABS market), and the always descriptive 'other loans' category have also been fairly robust. Conversely, real estate loans, trading assets and loans to other financial institutions, including hedge funds and the like, are basically flat for the last ten years. One could conclude these are perhaps the areas where alternative/non-bank capital could be deployed most profitably. Specifically, Transitional Funding Partners focuses specifically on collateralized real estate loans where we believe good risk-reward opportunities remain if one is diligent in underwriting. Also, other ASA entities focus on fixed income trading, which is the other area from which banks have retreated. It should also be noted that none of our funds use financial leverage (repo-type financing), because banks are not really providing it in a reliable way as they did pre-crisis.
Presumably the cash on the balance sheets will go away as the Fed unwinds the reserves banks are holding. However, one can speculate that getting in front of the $1-1.5Tn that is likely to move out of securities when riding the yield curve is no longer so attractive will be profitable if the assets have longer duration or may simply decrease returns if not. We'll hope their aversion to real estate lending continues for some time.
