How Kenya Plans to Stay Ahead of Inflation, Debt, and Climate Crises with a New Forecast Model

The IMF and Bank of Canada helped the Central Bank of Kenya modernize its core forecasting model, significantly improving the accuracy of inflation, growth, exchange-rate, and policy-rate projections while integrating fiscal policy and climate risks into monetary policy analysis. The upgraded framework is expected to strengthen economic decision-making, improve policy coordination, enhance investor confidence, and help Kenya better manage inflation, fiscal pressures, and climate-related shocks.

The International Monetary Fund (IMF), through its Monetary and Capital Markets Department, and experts from the Bank of Canada have helped the Central Bank of Kenya (CBK) overhaul its Core Quarterly Projection Model (QPM), the main tool used to forecast inflation, economic growth, interest rates, and exchange-rate movements. The upgrade comes as Kenya deepens its inflation-targeting framework, which aims to keep inflation at 5 percent, with a tolerance band of ±2.5 percentage points.

The report highlights that the previous model, first developed in 2014, no longer fully reflects Kenya's changing economic structure. The new version is designed to improve forecasting accuracy, strengthen monetary policy decisions, and provide policymakers with better tools to respond to fiscal, external, and climate-related shocks.

Better Forecasts for Better Policy Decisions

One of the report's key findings is that the revamped model performs significantly better than the previous version. Tests covering the period 2012–2023 showed substantial improvements in forecasting inflation, output, and exchange rates over horizons of up to two years.

The new framework separates inflation into three categories: core inflation (81% of the consumer basket), food inflation (12%), and energy inflation (7%). This allows policymakers to identify whether inflation is being driven by domestic demand, food supply disruptions, or global energy prices.

The model also introduces a stronger monetary policy rule that places greater emphasis on controlling inflation. According to the IMF, this should improve the CBK's ability to respond to price pressures while maintaining economic stability. More accurate forecasts can reduce uncertainty, improve policy timing, and help businesses and investors make better decisions.

Fiscal and Climate Risks Move to the Center of Analysis

A major innovation is the introduction of a dedicated fiscal policy block. Instead of relying on a broad fiscal indicator, the model now separately tracks government spending, revenues, and budget deficits. This enables policymakers to assess how public spending plans, tax measures, and fiscal consolidation efforts affect growth, inflation, and financial markets.

For governments across Africa and other developing regions, the Kenyan experience demonstrates the value of integrating fiscal and monetary analysis into a single forecasting framework. Development partners can also use such models to evaluate the macroeconomic impact of budget support programs, infrastructure investments, and debt-management reforms.

The report also breaks new ground by incorporating climate risks into monetary policy analysis. Using climate data from the World Bank, the model links rainfall patterns directly to food inflation. Simulations show that lower rainfall can increase food prices and create inflationary pressures that may require policy action. The IMF recommends expanding the framework using temperature and drought indicators as more data becomes available.

What It Means for Businesses and Investors

The upgraded model has important implications for private-sector stakeholders. More reliable forecasts of inflation, interest rates, and exchange rates can help businesses plan investments, manage borrowing costs, and reduce financial risks.

The report presents several risk scenarios. In a trade-shock scenario involving higher global tariffs, inflation remains elevated for almost two years and policy rates could rise to 15 percent by the third quarter of 2026. In contrast, a weak domestic confidence scenario results in lower inflation and lower interest rates. An unchanged policy scenario increases inflation by about 0.6 percentage points compared with the baseline outlook.

These simulations provide valuable information for banks, manufacturers, exporters, agribusiness firms, and investors, helping them prepare for different economic outcomes. The climate-risk analysis is particularly relevant for agriculture, food processing, insurance, and logistics companies that are highly exposed to weather-related disruptions.

Key Recommendations and the Road Ahead

The IMF concludes that the revamped QPM is a major step forward for Kenya's economic management. However, its success will depend on continued investment in data, institutions, and technical capacity.

The report recommends creating a unified forecasting database, improving coordination between fiscal and monetary authorities, aligning forecasting cycles with national accounts releases, and making Monetary Policy Reports more forward-looking. It also encourages the CBK to regularly evaluate model performance, refine climate-risk indicators, and strengthen staff training.

For policymakers, the upgraded framework offers a stronger basis for maintaining price stability and supporting sustainable growth. For development partners, it provides a more robust platform for assessing the impact of aid, investment, and reform programs. For the private sector, it promises greater transparency and predictability in Kenya's macroeconomic environment.

As global uncertainty, climate change, and fiscal pressures continue to challenge emerging economies, Kenya's experience demonstrates how modern forecasting tools can help governments make more informed decisions and build greater economic resilience.
