Ghana plans to roll out rebased Gross Domestic Product (GDP) and inflation data by mid-2027. This initiative, led by the Ghana Statistical Service (GSS), aims to modernise the country’s economic statistics.
The updated data will align more closely with current consumption patterns and productive activity. It will provide policymakers, investors, businesses, and development partners with more accurate macroeconomic indicators. This timing is critical as Ghana pursues fiscal consolidation and economic recovery.
This rebasing exercise is part of Ghana's broader effort to enhance policy credibility. Officials believe credible data is fundamental for sound policymaking, investor confidence, and effective development programming. Accurate GDP and inflation data are central to budget preparation, debt sustainability analysis, and tax policy decisions.
Government Statistician Dr. Alhassan Iddrissu confirmed this timeline during an appearance before Parliament’s Economic and Development Committee. Dr. Iddrissu highlighted that the schedule depends on timely funding from the Ministry of Finance. The rebasing process will update both the Consumer Price Index and GDP calculations. It will use new household and production data from the Ghana Living Standards Survey 8.
The current inflation basket still reflects spending patterns from 2017, despite some adjustments in 2021. Updating this basket will better capture changes in household consumption, urbanisation, and digital transactions. It will also reflect shifts in transport use, food markets, and the broader economic evolution over the past decade. The rebasing of GDP will offer a clearer picture of the economy's size and structure. This involves updating the base year used to measure national output.
Previous rebasing efforts have significantly impacted Ghana's economic standing. For example, in 2010, Ghana rebased its GDP from 1993 to 2006. This resulted in an upward revision exceeding 60%, elevating the country to lower-middle-income status. Analysts anticipate that the latest revision will again affect estimates of economic output, sectoral weightings, and inflation trends. The final outcome will depend on the methodology, data quality, and revised weighting structure.
For inflation, the rebasing could either raise or lower headline rates. This depends on how the new basket reflects current consumer behaviour. If items with faster-rising prices receive higher weights, inflation could appear stronger. If slower-moving items carry more weight, the headline rate might ease.
This exercise happens as Ghana’s inflation has recently slowed significantly. It fell from 23.5% in January 2025 to 3.7% in May 2026. However, recent increases in food prices are exerting renewed pressure on consumer prices. This raises concerns about the durability of the disinflation trend.
Dr. Iddrissu emphasised that sustaining price stability requires continued fiscal discipline. It also needs targeted investment in food systems, storage infrastructure, irrigation, and transportation networks. These investments are vital for easing supply constraints and improving market access. They will also reduce seasonal food price pressures that often influence Ghana’s inflation cycle.
The GSS considers statistical production a strategic national infrastructure investment. Credible data is crucial for investor confidence, business planning, and public accountability. Accurate and timely data will be essential for Ghana’s recovery. It will help avoid policy decisions based on outdated assumptions.
