Ghana Targets June 2027 to Complete GDP, CPI Rebasing

Ghana's government is aiming to complete the rebasing of the country's Gross Domestic Product (GDP) and Consumer Price Index (CPI) by the end of June 2027, a move intended to sharpen the accuracy and policy relevance of the West African nation's economic statistics.

Deputy Finance Minister Thomas Nyarko Ampem disclosed the timeline at the launch of the maiden edition of Ghana in Numbers 2025 in Accra, saying the Ministry of Finance is supporting the Ghana Statistical Service (GSS) to deliver both exercises within the proposed window.

"Government is supporting the rebasing of GDP and the Consumer Price Index. I urge Ghana Statistical Service to complete these exercises and related activities by the end of the second quarter of 2027 as planned," Ampem said.

Funding Already Committed

The rebasing effort has received significant financial backing. Government Statistician Dr. Alhassan Iddrisu revealed that GH¢207 million was allocated in the 2026 budget for the rebasing of GDP, CPI and related activities, with GH¢140 million already released . He appealed for the release of the remaining balance to enable completion by the second quarter of 2027.

The GSS chief also called for sustained domestic funding beyond 2026, warning that reliance on development partners leaves statistical production vulnerable to shifts in external support. "We ask that this commitment be sustained in every budget beyond 2026, so that statistical development rests on predictable domestically financed footing," he said .

Statistics Bill Pledged Urgent Attention

Ampem further pledged the Ministry's support for the proposed Statistics Bill, saying it would receive urgent attention once submitted and that the Ministry would work to facilitate its passage in Parliament. The GSS has been engaging stakeholders on the draft legislation, which is expected to strengthen the independence of the statistical service and improve coordination across the national statistical system .

Why Rebasing Matters

Rebasing involves updating the base year used to calculate GDP and CPI, incorporating structural changes in the economy that may not be captured under an outdated base. Ghana last rebased its GDP in 2018, a process that significantly altered sectoral shares—manufacturing's contribution to GDP more than doubled from 4.5% to 11.7%, while services contracted from 56.2% to 45.6% under the new methodology .

The upcoming rebasing comes as Ghana's economy was valued at GH¢1.4 trillion in 2025, with six per cent growth recorded. However, the GSS has flagged that the expansion has not translated into sufficient decent job creation, with nearly two million young people not in employment, education or training .

The Ghana in Numbers 2025 report, the first of what is planned as an annual publication, consolidates official statistics on population, the economy, social development and the Sustainable Development Goals, and is supported by an online portal providing district-level breakdowns .
