The Upstream Capital Costs Index (UCCI) is an index that measures the changes in the cost of capital for upstream oil and gas projects. The index is produced by IHS Markit and is widely used by the oil and gas industry to track changes in the cost of capital for upstream projects, such as the exploration and production of oil and gas.The UCCI takes into account the cost of capital for both conventional and unconventional oil and gas projects and is based on data from a range of sources, including industry reports, capital market data, and expert opinions. The index reflects the cost of capital for projects in different regions and across different stages of development, from early-stage exploration to late-stage production.The UCCI is used by oil and gas companies, investors, and analysts to assess the feasibility of upstream projects, to track the trends in capital costs, and to make informed investment decisions. For example, if the UCCI rises, it may indicate that the cost of capital for upstream projects is becoming more expensive, making it more difficult to finance new projects.It's important to note that the UCCI is just one of many factors that can influence the cost of capital for upstream oil and gas projects. Other factors, such as economic conditions, interest rates, and geopolitical events, can also have an impact on capital costs and should be considered when making investment decisions.
