### Dataset and methodology
- Novel dataset of large depreciations worldwide since 1971.
- Multi-step approach to accurately pinpoint large depreciation events on monthly data.
- Construction of large depreciation episodes that cover 24 months after the initial depreciation event.
- Month-level data enable granular characterization across multiple metrics: maximum depreciations, equilibrium depreciations, overshooting, and number of depreciation events within a single episode.

### Stylized facts and major findings
- (i) A few months into an episode, REER tends to appreciate unless there is an “aftershock” depreciation.
- (ii) Attempts to peg following the initial depreciation are associated with a higher likelihood of “aftershocks”.
- (iii) Equilibrium REER depreciations are largest when an IMF-supported program is put in place after the initial depreciation takes place.
- The dataset supports characterization of dynamics across various characteristics and groups: income, REER trajectory, number of events, exchange rate flexibility, and IMF-supported program status.

### Key metrics and analytics enabled by the dataset
- Month-level resolution for:
  - Maximum depreciations
  - Equilibrium depreciations
  - Overshooting
  - Number of depreciation events within a single episode
- Ability to identify “aftershock” depreciations and link them to policy responses such as attempts to peg.
