Economics - Capital controls and intervention

Hi All

I have been using the Schweser material to study, and today came across a few questions supposedly from Study session 4, Reading 13 (Currency Management) which I had no knowledge of whatsoever. The topics were:

  • Sterilized vs unsterilized interventions
  • Push/Pull factors surrounding capital controls

I couldn’t fid these mentioned in the Schweser book - is this a complete oversight on my part and the information is indeed there?

Additionally, could somebody be so kind as to explain the difference between a sterilized and unsterilized intervention with regard to capital controls?
