Warren Mosler, in his excellent recommendations for bank reform (similar to Bill Mitchell’s proposals
and others) focuses on the asset side of banks, and writes:
“The hard lesson of banking history is that the liability side of banking is not the place for
market discipline.”
Mosler doesn’t discuss this history or reasoning any further though. Can anyone elaborate on this banking history? And how it shows that disciplining the liability side of banking is not a good idea?
The asset side of a bank's balance sheet records the loans. Banks loan using the five "C"s of credit: character (usually based on credit history), capacity (ability to service the obligation from income), capital (net worth), collateral (assets that secure the debt), and conditions (state of the economy and borrower's role in it). Generally, it is assumed that banks will act prudently overall in extending credit, since their capital is being placed at risk. However, with the moral hazard created by, e.g., deposit guarantees, banks may fail to follow best practices. Therefore, government acting through its agencies impose regulations designed to offset this hazard. Often such regulations are imposed on the liability side, e.g., reserves or capital requirements.
However, the problem arises with the quality of the loans that are extended, and these show up on the asset side. Thus, government can address the asset side by regulating how credit is extended, e.g., down payment, and quality of collateral.
For example, the housing crisis developed out of imprudent credit extension, and the financial crisis grew out of the overvaluation of collateral. So a lot of loans got extended at a much higher value than was proper under best practices.
Government could have intervened with rules regarding the valuation of collateral when it was clear that the run-up in valuation was exceeding the ability to recover based on the underling collateral. Regulators should also have been sharper-eyed about the collusion of mortgage brokers and appraisers, especially after the FBI warned of rampant irregularities in the mortgage business as early as 2004.
