This paper presents a report on the Observance of Standards and Codes—Data Module for Cambodia. This report evaluates the quality of Cambodia’s macroeconomic statistics based on the IMF’s Data Quality Assessment Framework. While Cambodia’s Statistics Act provides a solid legal foundation, the country currently falls short of the Special Data Dissemination Standard, with 18 of 21 data categories failing to meet required coverage, periodicity, or timeliness. Significant challenges remain, particularly regarding the Consumer Price Index, which relies on expenditure weights over twenty years old, and the absence of quarterly gross domestic product estimates. Institutional constraints at the National Institute of Statistics (NIS) have hindered development, though the 2025 designation of the NIS as a National Public Administration Establishment marks a critical reform. Priority recommendations include expanding data sharing between the NIS, the Ministry of Economy and Finance, and the National Bank of Cambodia, as well as adopting machine-readable formats to improve accessibility. Achieving these standards is essential for enhancing transparency and supporting robust evidence-based policy in Cambodia.
