1、De Facto Classification of Exchange Rate Regimes and Monetary Policy FrameworkData as of July 31, 20061. This classification system is based on members actual, de facto, arrangements as identified by IMF staff, which may differ from their officially announced arrangements. The scheme ranks exchange
2、rate arrangements on the basis of their degree of flexibility and the existence of formal or informal commitments to exchange rate paths. It distinguishes among different forms of exchange rate regimes, in addition to arrangements with no separate legal tender, to help assess the implications of the
3、 choice of exchange rate arrangement for the degree of monetary policy independence. The system presents members exchange rate regimes and monetary policy frameworks to provide greater transparency in the classification scheme and to illustrate the relationship between exchange rate regimes and diff

The country pegs its currency within margins of 1 percent or less vis-vis another currency; a cooperative arrangement, such as the ERM II; or a basket of currencies, where the 精品资料

The monetary authority maintains the fixed parity through direct intervention (i.e., via sale/purchase of foreign exchange in the market) or indirect intervention (e.g., via the use of interest rate policy, imposition of foreign exchange regulations, exercise of moral suasion that co

Bands are either symmetric around a crawling central parity or widen gradually with an asymmetric choice of the crawl of upper and lower bands (in the latter case, there may be no preannounced central rate).
