One of the main concerns when considering Central Bank Digital Currency (CBDC) is the disintermediating effect on the banking sector in normal times, and even more the risk of a bank run in times of crisis. This paper extends the bank run model of Gertler and Kiyotaki (2015) by analyzing the...

We present a dynamic Rational Expectations (RE) bubble model of prices with the intention to evaluate it on optimal investment strategies applied to Bitcoin. Our bubble model is defined as a geometric Brownian motion combined with separate crash (and rally) discrete jump distributions associated...

Fractional reserve regimes generate fragile banking, and full reserve regimes (e.g., narrow banking) remove fragility at the cost of suppressing the role of banks as lenders. A Central Bank Digital Currency (CBDC) could provide safe money, but at the cost of potentially disrupting bank lending....

Purpose The goal of this work is to determine whether Bitcoin behaves as a safe-haven asset. In order to do so, the influence of Economic Policy Uncertainty (EPU) on Bitcoin returns and volatility was studied. Design/methodology/approach It is evaluated whether, when compared with the evolution...

We examine the liquidity effects of the euro area sovereign debt crisis, including its effects on euro area banks as a group, on intra-euro area financial flows, on the supply of and demand for collateral, and on international liquidity. The lending capacity of the euro area banking system has...

This paper studies how the interaction between policy maker's reputation for defending against speculative attacks and speculators' learning of the policy maker's type determines the emergence of speculative attacks and the outcome of regime change. If speculators receive conditionally...

This paper shows that the eurozone payment system does not effectively protect member states from speculative attacks. Suspicion of a departure from the common currency induces a terminal outflow of central bank money in weaker member states. TARGET2 cannot inhibit this drain but only protects...

Prompted by technological advances and a decline in cash usage, many Central Banks are investigating whether it would be possible to issue a digital complement to cash, a so-called Central Bank Digital Currency (CBDC). Despite ongoing research and occasional pilots, Central Banks have shied away...

This paper explores the interface between central banks and cryptocurrencies. Focusing on the European Central Bank (ECB), it identifies the potential threats that the rise of cryptocurrencies would pose to the basic and ancillary tasks of the ECB, in particular, its monetary policy operations...
