What it does
The Reserve Bank Act 1959 (Cth) is the constitutive statute of the Reserve Bank of Australia. It does three jobs at once. First, it preserves a body corporate, originally established under the Commonwealth Bank Act 1911 and continued by the Commonwealth Bank Act 1945, and renames it the Reserve Bank of Australia (section 7). Second, it sets the Bank's overarching objective and the architecture of three internal Boards through which the Bank discharges its functions. Third, it grants the operational powers a modern central bank needs: dealing in securities and foreign currency, issuing notes, banking the Commonwealth, and contributing to financial system stability.
Section 8AA states the overarching objective: to promote the economic prosperity and welfare of the people of Australia, both now and into the future. Section 8AB confers on the Bank the functions given to it by this Act or any other Commonwealth law. Section 8 grants broad general powers, including the power to receive money on deposit, borrow and lend, deal in bills and securities, deal in foreign currency and gold, give guarantees, issue drafts, underwrite loans, and do anything incidental.
