In market-based banking, asset side of a bank’s balance sheet is securitized and liabilities are based on wholesale borrowing such that the simple assets (loans, bonds, reserves) -liabilities (deposits, capital) balance of regular banking is scaled up into a chain of complex interconnected balance sheets of multiple intermediate entities which are outside the regulatory framework that governs banks, i.e. in the ‘shadows’. Before the crisis, banks would offload the loans to Special Purpose Vehicles (SPV) which securitized them as Asset-backed Securities (ABS) which combined with Credit Default Swaps (CDS) from insurance companies became Collateralized Debt Obligations (CDO). These CDOs, stamped dubiously by credit ratings agencies, were coupled with interest rate swaps (IRS) and liquidity puts by the owning bank.
The product were issued as short-term Asset-backed Commercial Paper (ABCP) by a Structured Investment Vehicle (SIV) or used as a source of funding in the repo market. Finally, the investment in ABCPs and repo came from money market mutual funds (MMMF) which were saddled with savings. However, the SPVs and SIVs were not state-regulated entities which allowed a toxic, subprime securities to grow at a “grotesque scale” while the complicated engineering of securitization which allowed banks to earn more through fees. In regular banking, this commodification of both the assets and liabilities side of the bank’s balance sheet wasn’t possible.
Regular banks have diverse sources of short-term borrowing in the form of depositors. While they are fragile because they borrow short and lend long, the market-shadow banking is much more fragile. This is because the primary source of funding from ABCP or repo was MMMFs, as Tooze write, “Lehman got its funding wholesale by tapping the cash pools and so too would the new mortgage lenders, including Lehman. This was the truly lethal mechanism at the heart of the crisis. Funds from money market cash pools were channeled into financing the holding of large balance sheets of MBS.” If this funding stopped, the system would crash as it did.
Moreover, in regular banking, all bad loans would sit on bank’s balance sheet as illiquid assets but couldn’t have taken down the financial system. In shadow banking, the securitizers held their own product, albeit off-balance sheet. This meant that risks were concentrated on a few large, unregulated balance sheets. As Tooze write, “contrary to the professed logic of securitization, hundreds of billions of private label MBS were not spread outside the banking system, but were stockpiled on the balance sheets of the mortgage originators and securitizers themselves.”
At the same time, to issue such risky loans in a regular banking system would have required the bank to adequate capital provisioning to account for risk. But the institutional setup of incentives in the shadow banking led to hardly any allocation of capital. In fact, as Tooze writes, “under the bank regulations prevailing until the early 2000s, assets parked off balance sheet in the SIV could be backed by a fraction of the capital that would be required if they were on balance sheet.” This would turn out to be one of the straws that broke the camel’s back and lead to a collapse of shadow banking.
