A crawling peg is a type of exchange rate system where a country's central bank adjusts the exchange rate in small increments over time. This allows for a gradual adjustment of the currency's value relative to another currency or basket of currencies. Synonyms for crawling peg can include adjustable peg, managed float, or flexible exchange rate regime. In contrast to a fixed exchange rate system, a crawling peg allows for some degree of flexibility in the exchange rate, which can help to promote stability in the economy. However, it also requires careful monitoring and management by the central bank to avoid destabilizing movements in the exchange rate.
