| Tiivistelmä: | This paper investigates the effect of central bank interventions on the weekly returns and volatility of the DEM/USD and YEN/USD exchange rate returns. In contrast with previous analyses, it allows for regime-dependent specifications and investigates whether official interventions can explain the observed volatility regime switches. It is found that, depending on the prevailing volatility level, co-ordinated central bank interventions can lead to either a stabilizing or a destabilizing effect. This paper's results lead to challenge the usual view that such interventions always imply increases in volatility. |
