Ethiopia's constitution creates one of Africa's most decentralised federal systems on paper, with regional states holding substantial authority over their own affairs. The fiscal data shows that decentralisation, in practice, is increasingly being driven by something more mundane: the federal government running out of money to send. According to the International Monetary Fund, Ethiopian regional states are responsible for executing approximately 50 per cent of aggregate general government expenditure, yet the real value of the federal block grants required to fund these mandates is structurally contracting. The World Bank's latest Ethiopia Public Expenditure Review puts the scale of that contraction plainly: federal block grants to regional states have declined from approximately 6.5 per cent of gross domestic product a decade ago to below 3.5 per cent by the end of 2025.

The distribution of national revenue is governed by a constitutional transfer formula administered by the House of Federation, designed to calculate regional allocations based on population, developmental disparities between regions, and each region's own revenue-raising effort. In a country as large and administratively varied as Ethiopia, a formula-based approach is the only practical way to allocate a shared national pool across very different regional economies. Historically, this mechanism functioned to maintain a baseline level of fiscal equivalence across Ethiopia's regional states. But a formula can only distribute what arrives in the pool, and what arrives in the pool has been shrinking. Because the constitution largely prohibits regional governments from borrowing independently without Ministry of Finance approval, state-level administrations remain highly exposed to the central treasury's liquidity position -- they cannot simply raise their own debt to cover the gap. As the federal government directs a growing share of domestic revenue toward servicing both internal borrowing and restructured external liabilities, the residual capital available for block grants systematically shrinks. Regional governments have responded by deploying parallel mechanisms to bridge their deficits, including informal levies on domestic trade routes and the retention of corporate taxes legally designated for the federal treasury -- a quiet fragmentation of the national tax base that is now showing up in macroeconomic data.

The analytical core of the regional fiscal crisis is the compounding effect of the sovereign's currency reform. Following the transition to a floating exchange rate framework in July 2024, the birr experienced a severe and sustained depreciation. National Bank of Ethiopia audited financial data revealed that the central bank itself incurred approximately 445 billion birr in unrealised losses, strictly from the revaluation of foreign-currency liabilities. For regional governments, this acted as a transmission mechanism, carrying federal-level currency exposure directly into state-level budgets. As inflation remained elevated through 2025 and into 2026, the purchasing power of the nominal block grants distributed by the House of Federation was severely eroded. Regions must procure imported medical supplies, construction materials, and infrastructure components at global market prices. They receive their federal allocations in a currency that buys less of those things every quarter. The grant on paper has not necessarily fallen in nominal birr terms -- what it can actually purchase has.

Restoring fiscal space at the federal level is now the immediate priority, and Ethiopia has made real progress on the largest single constraint: external debt. The country reached an agreement in principle with its Official Creditor Committee under the G20 Common Framework covering the restructuring of approximately $8.4 billion in outstanding public debt, with bilateral agreements signed with France and China in early 2026 following the country's December 2023 default. This follows an extended period of heavy borrowing for infrastructure from bilateral and multilateral creditors that had left debt service consuming a disproportionate share of federally collected indirect taxes and customs duties -- precisely the revenue that would otherwise flow into the block grant pool.

The other side of the equation is domestic revenue. Data from the Ministry of Finance and the World Bank indicates that Ethiopia's tax-to-GDP ratio fluctuates between 7 and 11 per cent, well below regional benchmarks, driven primarily by the scale of the informal economy operating outside formal documentation. Regularising these informal sectors is not simply an administrative housekeeping exercise. It is the precondition for broadening the tax base and for building the foundational architecture of a national social security system -- both of which would, eventually, ease the pressure on the transfer formula itself. In the meantime, the government is prioritising Foreign Direct Investment over further sovereign borrowing to raise capital. The sequencing matters here: financial institutions and local stakeholders increasingly advocate for comprehensive contractual agreements to precede the issuance of operational licences, with gatekeeping mechanisms designed to secure domestic value retention in sectors such as agriculture and mineral extraction, rather than allow a purely extractive investment pattern to take hold.

Alongside this, the state is deploying infrastructure to generate external revenue at scale. In January 2026, construction began on the $12.5 billion Bishoftu International Airport, designed to eventually process 110 million passengers annually and positioned to integrate aviation capacity with logistics and supply chain distribution -- the kind of infrastructure that could allow Ethiopia to export coffee, wheat, and spices more efficiently, and to compete for the intercontinental transit traffic currently dominated by Gulf hubs. This developmental strategy contrasts with Rwanda's model of a smaller, centralised, services-and-technology hub; Ethiopia's scale, agricultural base, and geography position it instead as a potential continent-wide food basket and supply chain anchor, energy generation constraints notwithstanding.

This dynamic of fiscal fragmentation under a strained federal structure closely mirrors patterns observed in Nigeria's federal architecture. According to African Development Bank analysis, Nigerian state governments rely heavily on centralised allocations from the Federation Account Allocation Committee, which fluctuate with federal oil revenues and external debt servicing costs. When macroeconomic shocks deplete the central revenue pool in Abuja, structurally weaker Nigerian states rapidly face operational pressure of their own. For both Ethiopia and Nigeria, the data points to the same underlying mechanism: a constitutional federal model can maintain institutional cohesion only for as long as the federal centre retains the aggregate fiscal capacity to reliably subsidise its constituent states. When that capacity erodes, power does not disappear. It simply moves to wherever the money is actually being raised and spent -- which, increasingly, is the regions themselves.
