This article reviews the conceptual issues surrounding market discipline for banks and describes to what extent market discipline could complement supervisory activities. The potential of market discipline has been explicitly recognised in the New Basel Accord. In addition to capital requirements (Pillar I) and supervisory review (Pillar II), the Accord provides for a greater role of financial markets in complementing traditional supervisory activities by asking banks for increased transparency with regard to their operations (Pillar III). This article puts Pillar III in the broader context of direct and indirect market discipline. It is argued that both direct and indirect market discipline should be enhanced by the transparency requirements of the New Capital Accord, but that other conditions may also need to be met in order for market discipline to become more effective. Nevertheless, the article also shows that aggregated market prices can play a useful role in monitoring banking sector stability.

This paper provides an explanation for the observation that banks hold on average a capital ratio in excess of regulatory requirements. We use a functional approach to banking based on Diamond and Rajan (2001) to demonstrate that banks can use capital ratios as a strategic tool for renegotiating loans with borrowers. As capital ratios affect the ability of banks to collect loans in a nonmonotonic way, a bank may be forced to exceed capital requirements. Moreover, high capital ratios may also constrain the amount a banker can borrow from investors. Consequently, the size of the banking sector may shrink.

This Basel Committee working paper is a study of the markets for banks' securities in ten countries (Belgium, France, Germany, Japan, the Netherlands, Spain, Sweden, Switzerland, the United Kingdom, and the United States). It aims at contributing to the assessment of the potential effectiveness of direct and indirect market discipline. This is achieved through collecting a rich set of data on the detailed characteristics of the instruments used by banks to tap capital markets, the frequency and size of their issuance activity, and the share of issuing banks in national banking systems. Further, information is collected on the amounts of debt and equity outstanding and about trading volumes and liquidity. Developments over the period from 1990-2001 are evaluated.

The paper focuses on subordinated bonds among banks' debt instruments, because they are the prime class of uninsured instruments suited to generate market discipline and have been proposed by some observers as a mandatory requirement for banks.

The study eamines the interactions between real exchange rates, current accounts and capital account balances in Poland, Hungary and the Czech Republic. The empirical investigation leads to a strong endorsement of more flexible exchange rates in the present stage of the economic transformation process of the former socialist countries in Central and Eastern Europe. Exchange rate flexibility allows more independent monetary policies that focus on financing structural adjustments and institutional changes in transition economies. However, the integration process with the European Union and more remote considerations of possible accession to the European Monetary Union will require a gradual move to fixed exchange rates and to an exchangerate-based monetary policy.
