Is this LOS actually asking for the difference between Fixed and Crawling Peg? I don’t see how Fixed and Pegged are different unless it’s a crawling peg.
Fixed- set to a specific exchange rate. Peg- range of applicable exchange rates. Visited and adjusted regularly. Both violate supply and demand of currency via gov interaction.
It’s probably interchangeable, but if forced to, I would say fixed is when the the price of a currency is set to gold or some other similiar asset, i.e., it is fixed to something stable, while pegged is simply a currency’s price set to another currency’s price. I don’t have my books, this is just a guess.
