His Majesty's Treasury, occasionally referred to as
the Exchequer, or more informally
the Treasury, is a department of His Majesty's Government responsible for developing and executing the government's public finance policy and economic policy. The Treasury maintains the Online System for Central Accounting and Reporting (OSCAR), the replacement for the Combined Online Information System (COINS), which itemises departmental spending under thousands of category headings, and from which the Whole of Government Accounts (WGA) annual financial statements are produced.
