Securitization vehicles are a central component of what is often referred to as the "shadow banking" system. As the name implies, shadow banking is not a part of the financial system that's generally considered to be transparent. Indeed, increasing shadow banking transparency was at the top of Fed governor Daniel Tarullo's list of policy prescriptions in a June 2012 speech:
First, we should create greater transparency with respect to the various transactions and markets that comprise the shadow banking system. For example, large segments of the repo market remain opaque today. In fact, at present there is no way that regulators or market participants can precisely determine even the overall volume of bilateral repo transactions--that is, transactions not settled using the triparty mechanism.
There seems to be growing recognition, however, that the securitization aspect of shadow banking actually increases financial market transparency by moving out into the open assets that are hidden beneath opaque bank balance sheets.
For example, a March 2012 study (p.11) on shadow banking by ICMA's European Repo Council, which itself drew upon a 2010 New York Fed paper, noted that by removing assets from banks,
Securitisation potentially involves the market in the supervision of banks, by providing third-party discipline and the market pricing of assets that would be opaque if left on a bank balance sheet.
In a July 2012 Financial Times op-ed, Sebastian Mallaby likewise noted that
Before securitisation, banks made loans and held them; investors who bought bank shares got an opaque bundle of exposures. Now, thanks to securitisation, investors can cherry-pick the risks that suit them.
And as picked up on by Dealbreaker's Matt Levine, in an August 2012 paper William Bratton and Adam Levitin more generally argued that
Even though the conventional operating company’s debt can be issued pursuant to a much simpler contract, market’s overall analysis will have to grapple with the factual complexity of the company and its business; there will be inevitable opaque patches in its profile....A synthetic [read really "structured product"], in contrast, is completely transparent — the assets are there on a list for all to see, each rated by a credit rating agency.
But what about the reputation for opaqueness that securitization vehicles in the form of mortgage-backed collateralized debt obligations (CDOs) earned after the financial crisis? That reputation is undeserved, according to Philadelphia Fed researchers:
One of the enduring myths of the crisis is that loan-level data on the mortgage securities in these CDOs were not available to properly value these CDOs. Loan-level data were available on most securities directly through Intex, with data on most others available from third-party vendors. Disclosures on securities recommended in the reforms by the IOSCO Technical Committee...were already mostly available for the [structured finance asset-backed security] CDOs. For investors, it was all available upon request.
So while aspects of the shadow banking system are certainly less transparent than traditional banking, it is a mistake to think that shadow banking vehicles in all instances reduce transparency. When it comes to banks and other credit originators, a core element of shadow banking--securitization--increases the market's ability to scrutinize assets that would otherwise be held by originators.
The implication of this insight for bank investors is to ask themselves why they would buy bank bonds as opposed to those issued by securitization vehicles. For regulators, an implication is that a possibly overlooked consequence of reforms that reduce securitization activity is undermining the ability of investors to price financial assets more accurately.
