This paper presents a rule for foreign exchange interventions (FXI), designed to preserve financial stability in floating exchange rate arrangements. The FXI rule addresses a market failure: the absence of hedging solution for tail exchange rate risk in the market (i.e. high volatility). Market...

This study considers emerging market central bank interventions motivated by international reserve management. Emerging market central banks use currency intervention as a policy tool against exchange rate movements and accumulate international reserves as an insurance against sudden stops or...

Using an agent-based model (ABM) with fundamentalists and chartists, prone to develop bubbles and crashes, we demonstrate the usefulness of direct market intervention by a policy maker, documenting strong performance in preventing bubbles and drawdowns and augmenting significantly the welfare of...

On August 11 2015, China revamped its procedure of setting the official central parity of the renminbi (RMB) against the US dollar. Our empirical investigation shows that the intertemporal dynamics of China's central parity are not the same before and after this policy change. They are more...

I find that the U.S. dollar appreciates before contractionary monetary policy decisions at scheduled Federal Open Market Committee meetings and depreciates before expansionary decisions. The federal funds futures rate forecasts these dollar movements with a 22% R2. A high federal funds futures...

From September 2011 to January 2015, the Swiss National Bank (SNB) implemented a minimum exchange rate regime (i.e. a one-sided target zone) vis- à-vis the euro to fight deflationary pressures in the aftermath of the Great Financial Crisis. During this period of unconventional monetary policy,...

In this paper we present new evidence on the positive correlation between returns from technical trading rules and periods of central bank intervention. To that end, we evaluate the profitability of a trading strategy based on nearest-neighbour (nonlinear) predictors, which may be viewed as a...

Academic literature on foreign exchange market intervention in emerging market countries has grown in recent years. Until now, existing studies have ignored the possible feature of time varying motives and impact effects for/of interventions as well as the relationship to underlying economic and...

In this work, assuming as a model the Multifractional Processes with Random Exponent (MPRE), we propose a simulation algorithm able to replicate financial time series, specifically pertaining to the FX market. We show how, properly choosing the functional parameter of the MPRE, the simulated...
