The paper constructs indices of financial system soundness and regulatory governance, based on country data collected from the Financial Sector Assessment Program (FSAP). Regression results indicate that regulatory governance has a significant influence on financial system soundness, along with variables reflecting macroeconomic conditions, the structure of the banking system, and the quality of political institutions and public sector governance. The results also indicate that good public sector governance amplifies the impact of regulatory governance on financial system soundness. JEL Classification Numbers: 017, P16, G28, G21, D78

This paper explores the relationship between the level and management of public debt and financial stability, and explains the channels through which the two are interlinked. It suggests that the broader implications of a debt management strategy and its implementation should be carefully analyzed by debt managers and policy makers in terms of their impact on the government's balance sheet, macroeconomic developments, and the financial system.

We analyze how bank profitability impacts financial stability from both theoretical and empirical perspectives. We first develop a theoretical model of the relationship between bank profitability and financial stability by exploring the role of non-interest income and retailoriented business models. We then conduct panel regression analysis to examine the empirical determinants of bank risks and profitability, and how the level and the source of bank profitability affect risks for 431 publicly traded banks (U.S., advanced Europe, and GSIBs) from 2004 to 2017. Results reveal that profitability is negatively associated with both a bank's contribution to systemic risk and its idiosyncratic risk, and an over-reliance on noninterest income, wholesale funding and leverage is associated with higher risks. Low competition is associated with low idiosyncratic risk but a high contribution to systemic risk. Lastly, the problem loans ratio and the cost-to-income ratio are found to be key factors that influence bank profitability. The paper's findings suggest that policy makers should strive to better understand the source of bank profitability, especially where there is an over-reliance on market-based non-interest income, leverage, and wholesale funding.
