In a landmark revelation during the Board orientation program at the Bank of Tanzania's Arusha branch, Director of Economic Research and Policy, Dr. Suleiman Missango, outlined a strategic shift towards an interest-based monetary policy framework. This novel approach is designed to harness the power of interest rates to manage money supply, curb inflation, and stimulate economic growth.

Explaining the complexity of the framework, Dr. Missango highlighted that the Central Bank, under this mechanism, would forecast and announce specific targets for inflation and projected output growth. These targets would then guide the adjustment of the central bank rate (CBR) – a key determinant in influencing interest rates and, consequently, the level of money in circulation.

"The path of interest rates is a critical tool in steering inflation towards the target and facilitating economic activities aligned with projected output growth," stated Dr. Missango. He emphasized that the Monetary Policy Committee (MPC) would play a pivotal role in deciding the trajectory of interest rates, thereby setting the monetary policy stance.

The CBR, according to Dr. Missango, acts as a barometer for the monetary policy stance. An increase signals a tightening stance, aimed at curbing inflationary pressures, while a decrease indicates an accommodative stance, designed to spur economic activity in the face of lower forecasted inflation.

In line with the East African Monetary Union (EAMU) Protocol, which mandates harmonizing monetary policy frameworks, Dr. Missango revealed that the interest rate-based model is expected to enhance the effectiveness of monetary policy. He emphasized that the Bank of Tanzania is actively implementing measures to align with this framework, including reducing market segmentation, conducting awareness sessions, enhancing forecasting models, and increasing transparency in monetary policy processes and outcomes.

Highlighting the process of monetary policy formulation, Dr. Missango explained that the Bank gathers macroeconomic data from both external and domestic sources. This data, including forecasts from trading partners and domestic agencies, informs the forecasting of inflation and GDP using sophisticated models. The aim is to obtain a model-consistent CBR or policy rate that aligns with the forecasted inflation and aids in achieving the targeted GDP.

Dr. Missango asserted that the interest rate-based monetary policy framework represents a significant step toward economic stability and growth. As the Bank of Tanzania continues its journey to implement these changes, the nation can anticipate a more transparent, communicative, and effective monetary policy.
