That the US financial system crashed and almost collapsed in 2008, causing a globally systemic financial crisis and precipitating a global recession is accepted fact. That US sub-prime lending funded the excess housing demand leading to a bubble in housing prices is also generally accepted. That extremely imprudent risks funded with unprecedented levels of financial leverage caused the failures that precipitated the global systemic crash is a central theme in most explanations. All of the various economic theories of why this happened, from the technicalities of security design (Gorton, 2009) to the failure of capitalism (Stiglitz, 2010) can be reduced to two competing hypotheses: a failure of market discipline or a failure of regulation and politics.
While still sifting through the wreckage and rebuilding the economy in mid July, 2010, the Congress passed the 2,315 page Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 to prevent a reoccurrence of this disaster. The disagreement in the debates regarding the appropriate policy prescription reflected the lack of a consensus on which of these two competing hypotheses to accept. The risk was that, following the precedent established in the Great Depression, politicians will blame markets and use the crisis to implement pre-collapse financial reform agendas and settle other old political scores. By having done just that, this Act worsens future systemic risk.
That there was little or no market discipline is obvious. Contrary to the deregulation myths, regulation and politics had long since replaced market discipline in US home mortgage markets. Regulators didn’t just fail systemically to mitigate excessive risk and leverage, they induced it. This didn’t reflect a lack of regulatory authority or zeal, as politicians openly encouraged it.
The politically populist credit allocation goals that promoted risky mortgage lending, whether or not morally justifiable, are fundamentally in conflict with prudential regulation. The system of “pay-to-play” politically powerful government sponsored enterprises (GSEs) was a systemic disaster waiting to happen. The recent advent of the private securitization system built upon a foundation of risk-based capital rules and delegation of risk evaluation to private credit rating agencies and run by politically powerful too-big-to-fail (TBTF) government insured commercial banks and implicitly backed TBTF investment banks was a new disaster ripe to happen. Easy money and liquidity policies by the central bank in the wake of a global savings glut fueled a competition for borrowers between these two systems that populist credit policies steered to increasingly less-qualified home buyers. This combination created a perfect storm that produced a tsunami wave of sub-prime lending, transforming the housing boom of the first half decade to a highly speculative bubble. The bubble burst in mid-2007 and the wave crashed on US shores in the fall of 2008, reverberating throughout global financial markets and leaving economic wreckage in its wake.
By the time the financial system finally collapsed bailouts and fiscal stimulus were likely necessary even as they risked permanently convincing markets that future policy will provide a safety net for even more risk and more leverage. Given this diagnosis, how to impose market and regulatory discipline before moral hazard behavior develops is the most important and problematic challenge of systemic financial reform.
The public policy prescription is simple and straightforward. Prudential regulation remains necessary so long as government sponsored deposit insurance is maintained, which seems inevitable. Prospectively the traditional regulatory challenge of promoting market competition and discipline while safeguarding safety and soundness remains paramount. But the prudential regulation of commercial banks needs to be de-politicized and re-invigorated, with greater reliance on market discipline where public regulation is most likely to fail due to inherent incentive conflicts. This means sound credit underwriting and more capital, including closing the off balance sheet loopholes typically employed by big banks and eliminating the incentives for regulatory arbitrage. Universal banking should remain, but divested of hedge fund and proprietary trading activity. In addition, firms that are “too big to fail” (TBTF) are probably too big to be effectively controlled by regulators and should either be broken up or otherwise prevented from engaging in risky financial activities by reducing or eliminating their political activities.
Most importantly, the two main sources of TBTF systemic risk and subsequent direct government bailout cost, Fannie Mae and Freddie Mac, no longer serve any essential market purpose. The excess investor demand for fixed income securities backed by fixed rate mortgages that fueled their early growth is long gone and now easily met by Ginnie Mae and Federal Home Loan Bank securities alone, as fixed nominal life and pension contracts have largely been replaced by performance and indexed plans. Fannie Mae and Freddie Mac should be unambiguously and expeditiously liquidated subsequent to implementing an adequate transition plan for mortgage markets.
