The currency in Chile is the Chilean peso. There are coins (1, 5, 10, 50, 100 and 500 pesos) and notes (1000, 2000, 5000, 10000 and 20000 pesos). A new 5000 peso bill was introduced on September 24, 2009. Since then, other new bills have also been issued. The old notes will be slowly phased out.  In the links below you can see all the bills by clicking on the denominations in the left hand column. The new 1000, 2000 and 5000 bills are made of a polymer and feel more like plastic than paper to the touch.

 The exchange rate fluctuates daily and currently is around Ch$470 to US$1.00 (January, 2013). Chile has a very low rate of inflation, less than 3 % in 2012. Chile has a stable and efficient banking system. There are a large number of retail banks with branches throughout the country. ATMs are common in large cities and found not only in banks, but in shopping centres, subway stations, gas stations, many stores, particularly pharmacies, supermarkets and departmental stores. Many of these machines permit the use of foreign bank cards. Most ATMs now charge a fee for cash withdrawn with a foreign credit card. It is between 2000 and 2500 pesos per transaction. Currently the Banco del Estado, Scotiabank and it associates do not charge. Money can be exchanged in banks, hotels or in specialist exchange houses. Exchange houses will give the best rate. There is free exchange and money should no more be exchanged on the street than in the USA or Europe. 

For travelers in Northern Patagonia, be aware that south of Puerto Montt ATM machines or establishments taking credit cards may not be commonly available.  If you are traveling outside of Coyhaique on the Carreterra Austral ATM's are rare  and most hotels, hostels and restaurants require cash.  There are ATM's on Easter island and in San Pedro de Atacama, but due to the high demand and their relative isolation, these often run out of cash. In Futaleufu. there is one ATM, which only accepts Mastercard or Cirrus, otherwise bring cash. You can change money or travelers checks at the Banco Estado, and money at several tour agencys.
