Top 10 Most Indebted African Countries by Debt-to-GDP Ratio Spark Debate Online

A recently circulated ranking highlighting the 10 most indebted African countries by total debt-to-GDP ratio has triggered heated discussions across social media platforms, particularly among Nigerian commentators.

The list, which compares national debt levels to the size of each country’s economy, does not include Nigeria among the top 10 — a development that quickly became the focal point of debate.

Supporters of President Bola Ahmed Tinubu hailed the omission as proof of prudent fiscal management under his administration. Some described it as a rebuttal to critics who had predicted that Nigeria’s borrowing levels would push it into the highest-risk category on the continent.

However, others urged caution, arguing that debt-to-GDP ratio alone does not provide a complete picture of a country’s financial health.

Understanding Debt-to-GDP Ratio

Debt-to-GDP ratio measures a country’s total public debt relative to its Gross Domestic Product (GDP). It is commonly used by economists and institutions such as the International Monetary Fund (IMF) and the World Bank to assess a nation’s ability to repay its obligations.

A higher ratio may suggest potential repayment difficulties, while a lower ratio often indicates stronger capacity to manage debt — at least in theory.

Several African economies frequently cited in high debt-to-GDP discussions include Egypt, South Africa, Kenya, Zambia, Senegal, and Rwanda — countries that have, at various times, recorded elevated debt ratios relative to their economic output.

Nigeria’s Position and the Broader Context

Nigeria’s absence from the top 10 list surprised some observers. For critics of the current administration, it raised questions about whether the ranking reflects the most recent fiscal data. Others argued that the focus should not be on league tables but on deeper structural indicators.

Economists note that while debt-to-GDP ratio is important, revenue-to-GDP ratio is equally critical. Nigeria has historically recorded one of the lowest government revenue-to-GDP ratios in Africa, meaning the government earns relatively little compared to the size of its economy.

This creates a unique challenge: even if the debt-to-GDP ratio appears moderate, debt servicing can consume a significant portion of government income. In recent years, Nigeria has spent a substantial share of its revenue on servicing existing debt — leaving less fiscal space for infrastructure, healthcare, education, and job creation.

In contrast, countries such as South Africa and Egypt, despite higher debt-to-GDP ratios, generate comparatively stronger government revenues and attract larger volumes of foreign investment, which can improve debt sustainability.

Political Reactions

The ranking quickly took on political undertones. Supporters of President Tinubu described the data as evidence that fears of runaway borrowing were exaggerated. Some critics, however, countered that total borrowing under successive administrations — including the current one — remains historically high.

Debate also extended to proposed tax reforms under the Tinubu administration, with some commentators arguing that increasing Nigeria’s tax-to-GDP ratio is necessary to strengthen revenue generation and improve debt sustainability.

The Bigger Question

Ultimately, analysts emphasize that debt itself is not inherently negative. Many advanced economies operate with high debt levels, provided borrowing is invested productively and economic growth remains strong.

The more pressing question for Nigeria and other African economies is whether borrowed funds are being used to stimulate growth, expand productive capacity, and improve living standards.

As the online debate shows, statistics can be interpreted in different ways. While Nigeria’s absence from the top 10 may offer political talking points, sustainable economic management will depend on long-term fiscal discipline, improved revenue mobilization, and strategic investment.
