Motivated by the tension first revealed during the global financial crisis between thedomestic and international financial stability obligations of central bank reserve managers,this paper offers some reflections along four main lines. First, the paper highlights howofficial reserve management...

The European Council's decisions to implement the De Larosiere recommendations for a reformed approach to micro-level financial supervision and a new European Systemic Risk Board (ESRB) are to be welcomed. The ECB's central role in the ESRB is also to be welcomed. However, the limited role...

We study determinants of sovereign portfolios of Spanish banks over a long time-span, starting in 2008. Our findings challenge the view that banks engaged in moral hazard strategies to exploit the regulatory treatment of sovereign exposures. In particular, we show that being a weakly capitalized...

This paper describes how behavioral elements are relevant to financial supervision,regulation, and central banking. It focuses on (1) behavioral effects of norms (social, legal,and market); (2) behavior of others (internalization, identification, and compliance); and(3) psychological biases. It...

We develop a stylized balance sheet framework to help identify ‘quasi-fiscal’ components of central bank crisis interventions and show how sources of fiscal risk are created from both the new claims and how they are funded. Combining central bank balance sheet data with survey evidence from...

This paper explores how non-U.S. central banks behave when firms in their economies engage in currency mismatch, borrowing more heavily in dollars than justified by their operating exposures. We begin by documenting that, in a panel of 53 countries, central bank holdings of dollar reserves are...

This paper surveys dynamic stochastic general equilibrium models with financial frictions in use by central banks and discusses priorities for future development of such models for the purpose of monetary and financial stability analysis. It highlights the need to develop macrofinancial models...

We consider how fear of model misspecification on the part of the planner and/or the households affects welfare gains from optimal macroprudential taxes in an economy with occasionally binding collateral constraints as in Bianchi (2011). On the one hand, there exist welfare gains from...

We extend the New Keynesian (NK) model to include endogenous risk. Lower interest rates not only shift consumption intertemporally but also conditional output risk via their impact on risk-taking, giving rise to a vulnerability channel of monetary policy. The model fits the conditional output...
