  • Bank Leverage Ratios and Financial Stability


    Working Paper No. 849 | October 2015
    A Micro- and Macroprudential Perspective

    Bank leverage ratios have made an impressive and largely unopposed return; they are mostly used alongside risk-weighted capital requirements. The reasons for this return are manifold, and they are not limited to the fact that bank equity levels in the wake of the global financial crisis (GFC) were exceptionally thin, necessitating a string of costly bailouts. A number of other factors have been equally important; these include, among others, the world’s revulsion with debt following the GFC and the eurozone crisis, and the universal acceptance of Hyman Minsky’s insights into the nature of the financial system and its role in the real economy. The best examples of the causal link between excessive debt, asset bubbles, and financial instability are the Spanish and Irish banking crises, which resulted from nothing more sophisticated than straightforward real estate loans. Bank leverage ratios are primarily seen as a microprudential measure that intends to increase bank resilience. Yet in today’s environment of excessive liquidity due to very low interest rates and quantitative easing, bank leverage ratios should also be viewed as a key part of the macroprudential framework. In this context, this paper discusses the role of leverage ratios as both microprudential and macroprudential measures. As such, it explains the role of the leverage cycle in causing financial instability and sheds light on the impact of leverage restraints on good bank governance and allocative efficiency.

  • The Repeal of the Glass-Steagall Act and the Federal Reserve’s Extraordinary Intervention during the Global Financial Crisis


    Working Paper No. 829 | January 2015

    Before the global financial crisis, the assistance of a lender of last resort was traditionally thought to be limited to commercial banks. During the crisis, however, the Federal Reserve created a number of facilities to support brokers and dealers, money market mutual funds, the commercial paper market, the mortgage-backed securities market, the triparty repo market, et cetera. In this paper, we argue that the elimination of specialized banking through the eventual repeal of the Glass-Steagall Act (GSA) has played an important role in the leakage of the public subsidy intended for commercial banks to nonbank financial institutions. In a specialized financial system, which the GSA had helped create, the use of the lender-of-last-resort safety net could be more comfortably limited to commercial banks.

    However, the elimination of GSA restrictions on bank-permissible activities has contributed to the rise of a financial system where the lines between regulated and protected banks and the so-called shadow banking system have become blurred. The existence of the shadow banking universe, which is directly or indirectly guaranteed by banks, has made it practically impossible to confine the safety to the regulated banking system. In this context, reforming the lender-of-last-resort institution requires fundamental changes within the financial system itself.
