Constant purchasing power accounting (CPPA) is an accounting model that is an alternative to model historical cost accounting under high inflation and hyper-inflationary environments.^[1] It has been approved for use by the International Accounting Standards Board (IASB) and the US Financial Accounting Standards Board (FASB). Under this IFRS and US GAAP authorized system, financial capital maintenance is always measured in units of constant purchasing power (CPP) in terms of a Daily CPI (consumer price index) during low inflation, high inflation, hyperinflation and deflation; i.e., during all possible economic environments. During all economic environments it can also be measured in a monetized daily indexed unit of account (e.g. the Unidad de Fomento in Chile) or in terms of a daily relatively stable foreign currency parallel rate, particularly during hyperinflation when a government refuses to publish CPI data.
