Credit capital requirements in Internal Rating Based approaches require the calibration of two key parameters: probability default and loss-given-default. This letter considers uncertainty about these parameters models this an elementary way: it shows how estimation risk can be computed properly taken into account regulatory capital. We analyse standard real datasets: one composed by all corpor...

We explore the implications of risk-based capital requirements, à la Basel, for the conduct of monetary policy. A “bank balance-sheet channel” of monetary policy is identified, which operates through bank capital and influences the bank’s loan decision. Using a dynamic banking model, we endogenize the capital decision and show that banks are likely to hold capital above the regulatory minimum t...

This paper addresses the impact of dynamic risk management on bank risk taking. We show that when banks earn rents only from deposit insurance and can engage in risk management it is no longer in their interests to maximize risk; instead, they moderate their risk to increase their chances of survival. The paper also shows that the opportunity for risk management may change the impact of capital...

Traditional monetary theory has largely ignored the role of bank equity. Bank-centred accounts of how monetary policy affects the real economy usually focus on the role of reserves and reserve requirements in determining the volume of demand deposits and, in the case of the bank lending channel, bank loans. As Benjamin Friedman (1991) observed, “Traditionally, most economists have regarded the ...

Article history: Received 21 August 2013 Accepted 15 November 2013 Available online 19 December 2013 Capital adequacy plays an important role in determining banking activities. A bank must hold a minimum level of capital to ensure sufficient funds to buffer against unexpected losses or adverse shocks. This study analyzes and compares Islamic and conventional banks in 14 Organization of Islamic ...

Fundamental economic principles provide a rationale for requiring financial institutions to use mark-to-market, or fair value, accounting for financial reporting. The recent turmoil in financial markets, however, has raised questions about whether fair value accounting is exacerbating the problems. In this paper, we review the history and practice of fair value accounting, and summarize the lit...

Can the usage of a risky numeraire with a greater than risk free expected return reduce the capital requirements in a solvency test? I will show that this is not the case. In fact, under a reasonable technical condition, there exists no optimal numeraire which yields smaller capital requirements than any other numeraire. 1 Statement and Proof of the Result Can the usage of a risky numeraire wit...

We analyse a general equilibrium model in which there is both adverse selection of and moral hazard by banks. The regulator has two tools at her disposal to combat these problems she can audit banks to learn their type prior to giving them a licence, and she can impose capital adequacy requirements. When the regulator has a strong reputation for screening she uses capital requirements to combat...
