From One Collateral Shortage to the Next


(Bloomberg) -- In 1863, with the US still reeling from a bloody civil war, a plan was launched in Washington to simultaneously fund its military loans and strengthen the nascent American banking system. We cannot maintain our nationality unless we establish a sound and stable financial system; and as the basis of it we must have a uniform national currency, Senator John Sherman urged at the time.

What followed was a program designed to replace the patchwork state rules that had for years allowed the countrys banks to sell their own private notes secured by loans or state bonds. Under the National Bank Acts of 1863 and 1864, banks could issue “national bank notes” that would be backed by the government, by depositing certain issues of US debt with the Treasury.

While the legislation helped fill federal coffers and became the basis for the Federal Reserve Act 40 years later, it arguably failed its second mandate as bank panics continued apace in the latter half of the 19th century. Instead of depositors demanding the return of private bank notes, they simply demanded national bank notes instead.

This nugget of US financial history comes courtesy of a new working paper from the Basel, Switzerland-based Bank for International Settlements. Its authors, famed economists Gary Gorton and Tyler Muir, argue that the National Banking Era bears an uncanny resemblance to more recent regulatory efforts to strengthen the global financial system in the aftermath of the 2008 crisis.

At issue is the systems tendency to manufacture safe securities in times when government-issued debt is in short supply. Prior to the financial crisis, for instance, Wall Streets securitization machine worked overtime to turn dodgy subprime home loans into triple-A rated securities. Not only did the resulting bonds satisfy the needs of a global savings glut desperate for investable assets, but the convenience of the securitized wrapper had the added benefit of turning the debt into suitable collateral for interbank loans in the vast repo market.

The story is told in the BIS chart below, in vivid black and white. It shows the steady decline of demand deposits backed by bank loans, and their subsequent replacement with privately-produced safe securities such as highly-rated asset- and mortgage-backed securities (ABS and MBS), asset-backed commercial paper (ABCP), and other ingredients of Wall Streets alphabet soup. In the late 19th century the need for such securities was made more urgent by the mounting scarcity of US government debt, the economists argue.

The creation of privately-produced safe debt is in part a response to a scarcity of government-produced safe debt, they write. The response to scarcity was not only increased private production of safe debt, but also increased mobility of the debt.

What happened next forms its own sizable chunk of US financial history. The repo market seized up in 2008, as concerns over the quality of the collateral underpinning short-term loans mounted during the collapse of the housing bubble. That culminated in the failure of Lehman Brothers, and the wider financial crisis.

Since then, regulators have embarked on an effort to strengthen the banking system through new rules requiring institutions to hold vast war chests of high-quality assets through the liquidity coverage ratio, or LCR, as well as new margin requirements for centrally-cleared derivatives trades.

In that sense, the LCR and its associated rules bear more than a little resemblance to the National Banking Era of more than 150 years ago, Gorton and Muir argue. 

It is likely that a system of immobile collateral that restricts certain forms of bank debt creation simply encourages other forms of bank debt to be created, they write. This is consistent with the growth in deposits during the National Banking Era. There is a remarkably strong correlation between Treasury supply and deposits. These new forms of bank debt are dangerous because they are typically not well understood or acknowledged, as deposits were not well understood in the National Banking Era and as shadow money (repo, ABCP etc.) were not understood until the recent crisis. In an effort to shore up one pillar of the financial system, regulators may inadvertently encourage a rerun of the same sort of behavior that help contribute to the 2008 crisis. New regulations do not address potential scarcities of safe debt. In fact, since the financial crisis, new regulations aim at returning to a financial system of immobile collateral.

The unanswered question here of course, is just what safe securities might be produced by a financial system faced with yet another collateral shortage.
