Kenya's fiscal trajectory for the past five years represents one of the most instructive case studies in the political economy of adjustment in sub-Saharan Africa. The combination of ambitious development spending, revenue underperformance, and rising debt service costs has placed the economy where it needs external support to keep operating, exposing the country’s structural weakness approach to public financial management.
The revenue challenge is foundational. Kenya Revenue Authority collections have been falling below the targeted figures embedded in successive budgets, showcasing challenges in tax administration and compliance, significant informal sector activity, and a narrow formal tax base. The KRA's capacity to enforce compliance among large taxpayers has improved, however, the large proportion of economic activity beyond the formal tax net remains unaddressed.
The consequences for debt dynamics haven’t been forgiving. Kenya's external debt, accumulated through a combination of Eurobond issuances, multilateral borrowing, and bilateral lending, particularly from China, now carries debt service costs that take up an estimated 60% or more of government revenue. This ratio, among the highest in sub-Saharan Africa, represents a fundamental constraint on the government's ability to allocate resources to development priorities.
The political economy of the Ruto administration's fiscal consolidation efforts has been complicated by the events of June 2024. The Finance Bill 2024, which proposed a range of new revenue measures including a housing levy and additional VAT provisions, triggered mass protests that led to its withdrawal. The protests, organised largely through social media and led by a generation of young Kenyans with no direct memory of previous IMF programmes, reflected a genuine public resistance to the burden of fiscal adjustment falling disproportionately on ordinary households.
The government's response, that is, withdrawing the Finance Bill, dismissing several cabinet members, and announcing a programme of expenditure reductions, has provided some fiscal relief but has not resolved the underlying structural challenges. The IMF programme, under the Extended Credit Facility and Extended Fund Facility arrangements, continues to provide critical balance of payments support and has been extended to accommodate the changed fiscal context. But the programme cannot substitute for the domestic political consensus required to implement sustained fiscal adjustment.
The path forward is not straightforward. Revenue mobilisation through broadening the tax base, that is, bringing more of the informal economy into the formal tax net, is a medium-term process that requires sustained investment in tax administration capacity. Expenditure rationalisation, particularly of the public sector wage bill, faces significant political economy constraints. The debt service burden will continue to crowd out development spending for the foreseeable future, regardless of the pace of fiscal adjustment.
