Central bank intervention; Survey expectations; Foreign exchange markets; Market micro-structure
Abstract :
[en] We analyze the relationship between interventions and volatility at daily and intra-daily
frequencies for the two major exchange rate markets. Using recent econometric methods to
estimate realized volatility, we employ bipower variation to decompose this volatility into a
continuously varying and jump component. Analysis of the timing and direction of jumps
and interventions imply that coordinated interventions tend to cause few, but large jumps.
Most coordinated operations explain, statistically, an increase in the persistent (continuous)
part of exchange rate volatility. This correlation is even stronger on days with jumps.
