The Bank of Ghana (BoG) has deployed Artificial Intelligence (AI) to strengthen its inflation forecasting and improve how it gathers and analyses economic data. This significant technological upgrade aims to provide more precise and timely information for critical monetary policy decisions.
First Deputy Governor Dr. Zakari Mumuni confirmed this development at the 4th Annual Statistics and Data Science Conference in Tamale. He explained that AI is part of the central bank's broader adoption of advanced modelling tools and big data technologies. These tools are already improving the accuracy of inflation predictions, even before official data releases.
This strategic integration of AI fits into Ghana's ongoing economic narrative, where accurate data is vital for stability. The BoG's move reflects a global trend among central banks to leverage technology for better economic management. This initiative follows the Governor's February 2025 charge to adopt a more proactive and precise approach to managing inflation, utilizing advanced analytics.
Dr. Mumuni stated, "We also employ machine-learning models to complement standard econometric models in forecasting GDP and performing text-mining analytics." He emphasized that technology is transforming financial supervision. Supervisors can now validate granular data as it arrives, identifying risks much earlier than with traditional manual spreadsheet methods.
The implications of this technological shift are substantial for Ghana's financial landscape. More accurate forecasts mean the Monetary Policy Committee can make better-informed decisions regarding interest rates and other policy tools. This could lead to more stable prices and a more predictable economic environment for businesses and consumers.
The BoG also uses econometric techniques and its Quarterly Projection Model within a Forecast and Policy Analysis System. These methods help identify emerging trends, assess risks, and consider the likely outcomes of different policy choices. This comprehensive approach ensures that policy decisions are grounded in robust analysis.
However, Dr. Mumuni cautioned that technological tools cannot replace human judgment in economic policymaking. He stressed, "Technology can strengthen our intelligence, but it does not remove the need for human judgment." This highlights the importance of balancing advanced analytics with expert human insight.
The First Deputy Governor also noted that the Bank continues to collect information directly from communities and businesses nationwide. Research Department staff track prices and conduct confidence surveys in markets across the country, including Tamale. This ensures that policy decisions reflect Ghana's diverse economic experiences, not just those of Accra.
Dr. Mumuni urged statisticians and researchers to ensure new technologies complement, rather than replace, sound statistical methods. He advised, "New data should complement—not replace—properly weighted and nationally representative measures." He also encouraged closer collaboration between researchers and policymakers to address economic challenges effectively.
This deployment of AI represents a significant step forward for the Bank of Ghana in its mission to maintain price stability and foster sustainable economic growth. Businesses and investors will closely watch how these enhanced forecasting capabilities translate into more effective monetary policy and a more resilient Ghanaian economy.
