We analytically derive optimal central bank portfolios in a minimum variance framework with two assets and quot;transaction demandsquot; caused by sudden stops in capital inflows. In this model, the transaction demands become less important relative to traditional portfolio objectives as debt to...

Since the late-1990s, the global economy is characterised by historically low risk premia and an unprecedented widening of external imbalances. This paper explores to what extent these two global trends can be understood as a reaction to three structural shocks in different regions of the global...

The investment of the ECB reserves in US dollars and yen, delegated to a network of portfolio managers in the Eurosystem’s national central banks, involves a periodic assessment of performance against a common benchmark, controlled by the ECB and subject to revision on a monthly basis....

We analyse the international transmission of monetary policy shocks with a focus on the effects of foreign liquidity on the euro area. We estimate two domestic structural VAR models for the euro area and then we introduce a global liquidity aggregate. The impulse responses show that a positive...

We analytically derive optimal central bank portfolios in a minimum variance framework with two assets and "transaction demands" caused by sudden stops in capital inflows. In this model, the transaction demands become less important relative to traditional portfolio objectives as debt to reserve...

This paper offers new evidence on the emergence of the dollar as the leading international currency, focusing on its role as currency of denomination in global bond markets. We show that the dollar overtook sterling much earlier than commonly supposed, as early as in 1929. Financial market...

This paper reconstructs the forgotten history of mutual assistance among Reserve Banks in the early years of the Federal Reserve System. We use data on accommodation operations by the 12 Reserve Banks between 1913 and 1960 which enabled them to mutualise their gold reserves in emergency...

We investigate whether the role of national currencies as international reserves was fundamentally altered by the shift from fixed to flexible exchange rates (what we call the “upheaval hypothesis”), a view that gained adherents following the collapse of the Bretton Woods System. We extend...

The notable increase in international reserve holdings over the past decade and their use during the global financial crisis of 2008/2009 has sparked renewed interest in the analysis of the optimal level of reserve holdings, in particular in countries which are subject to sudden stops. Less...

This paper analyses the impact of the shift away from a US dollar focus of systemically important emerging market economies (EMEs) on configurations between the US dollar, the euro and the yen. Given the difficulty that fixed or managed US dollar exchange rate regimes remain pervasive and...
