### Overview
- Objective: Achieve price stability by stabilizing the value of the currency.
- Central premise: The effectiveness of an exchange rate peg as a nominal anchor crucially depends on its operational design.
- Scope: Guidance on implementing bilateral exchange rate pegs, pegs to a basket of currencies, crawling pegs, and currency bands, with emphasis on long-run price stability.

### Key operational considerations
- Choosing an appropriate anchor currency:
  - Align anchor currency choice with trade and financial linkages to enhance credibility and reduce exchange rate volatility.
- Setting the rate of crawl (for crawling pegs):
  - Determine the rate of crawl consistent with inflation differentials and desired competitiveness dynamics.
- Designing bands:
  - Set band widths and intervention rules that balance credibility of the peg with flexibility to absorb shocks.
- Consistency with nominal anchor objectives:
  - Operational rules must be calibrated to ensure the peg effectively anchors inflation expectations over the long run.

### Implementation by peg arrangement
- Bilateral exchange rate pegs:
  - Operational focus on maintaining a stable bilateral rate with interventions and reserve management tailored to the chosen anchor.
- Basket pegs:
  - Design of basket composition and weights should reflect the currency exposure relevant for price stability.
- Crawling pegs:
  - Operationalizing requires transparent and rule-based specification of the crawl path and frequency.
- Currency bands:
  - Implement via clear rules for intramarginal and marginal intervention, surveillance, and communication to market participants.

### Monetary and foreign exchange operations
- Conducting operations consistent with the peg arrangement:
  - Use foreign exchange intervention, reserve management, and liquidity operations aligned with the chosen peg's operational rules.
- Communication and transparency:
  - Publish operational rules and intervention frameworks to strengthen credibility and manage market expectations.
- Interaction with domestic monetary policy:
  - Ensure liquidity management and interest rate policy are coordinated with the peg to maintain internal and external balance.

### Practical focus areas for policymakers
- Ensure operational design supports long-run price stability rather than short-term exchange rate objectives alone.
- Establish clear, rule-based operational procedures for interventions, reserve use, and adjustments to peg parameters.
- Align anchor selection and peg parameters (e.g., crawl rate, band width, basket weights) with the economy’s external exposures and inflation dynamics.
- Maintain robust foreign exchange reserves and reserve management practices to underpin credible interventions when needed.
- Monitor uncovered interest rate parity implications and manage interest rate differentials consistent with the peg.
