We present an incomplete markets model to understand the costs and benefits of increasing government debt in a low interest rate environment. Higher risk increases the demand for safe assets, lowering the natural rate of interest below zero, constraining monetary policy at the zero lower bound,...

We investigate the drivers of daily changes in the exchange value of the Chinese currency (CNY) since early 2016, when a new regime was introduced for setting the fix - the midpoint of the CNY's daily trading range against the U.S. dollar. Daily changes in the fix, which is announced just prior...

The share of U.S. dollar assets in the official foreign exchange reserve portfolios of central banks is sometimes taken as an indicator of dollar status. We show that the observed decline in the aggregate share of U.S. dollar assets does not stem from a systematic shift in currency preferences...

There is often speculation that the international roles of currencies may be changing. This paper presents the current status of these roles. The U.S. dollar continues to be the dominant currency across various uses. Yet, such a role may change over time. If this occurs, there could be...

Using novel monthly data for 226 euro-area banks from 2007 to 2015, we investigate the causes and effects of banks' sovereign exposures during and after the euro crisis. First, in the vulnerable countries, the publicly owned, recently bailed out and less strongly capitalized banks reacted to...

We have documented a regime change in the U.S. Treasury market post-Global Financial Crisis (GFC). We first derived bounds on Treasury yields that account for dealer balance sheet costs, which we call the net short and net long curves. We show that actual Treasury yields moved from the net short...

Building on the facility design and application experience from the period of the global financial crisis, in March 2020 the Federal Reserve eased the terms on its standing swap lines in collaboration with other central banks, reactivated temporary swap agreements, and then introduced the new...

At the 25th anniversary of the Maastricht Treaty, this paper reviews the merits of introducing a safe sovereign asset for the eurozone. The triple euro area crisis showed the costly consequences of ignoring the "safety trilemma". Keeping a national safe sovereign asset (the German bund) as the...

I develop a model where the sovereign debt capacity depends on the capitalization of domestic banks. Low-capital banks optimally tilt their government bond portfolio toward domestic securities, linking their destiny to that of the sovereign. If the sovereign risk is sufficiently high,...
