Guyana has discovered significant quantities of commercially viable oil offshore the coast of Guyana. In anticipation of this, the Government of Guyana has sought to implement a Sovereign Wealth Fund, which is intended to capture revenues from the oil and gas sector. This Fund, known in Guyana as the Natural Resources Fund, also intends to have, deposited into it, revenues from other extractive industries in Guyana. A number of issues must be examined within the context of Guyana’s macroeconomic stability and the public financial management framework in Guyana. This paper seeks to address these matters. It is divided into three (3) sections: 1. An overview of Sovereign Wealth Funds and Guyana’s proposed Fund; 2. The Fiscal Rule and the Management of the Fund; 3. Critical Perspectives of the Fund. This paper is based on the widely circulated ‘Green Paper’ published by the Ministry of Finance, Government of Guyana.
