Senegal's oil boom and its debt crisis are the same story

On Tuesday, Senegal's finance ministry invited its external creditors to a video call, hosted by IMF staff, to update them on the country's economy, its reform programme and its "debt treatment strategy". In plain English, that means restructuring. Weeks earlier the IMF had reached a staff-level agreement on a new three-year, $2.2 billion Extended Credit Facility, and the government had announced it would seek a debt treatment "to restore debt sustainability".

That would be unremarkable for an economy in recession. Senegal isn't in one. In 2025, its first full year as an oil producer, real GDP grew 6.7%. In the first quarter of 2025 alone, growth was estimated at 12.1%. By most headline measures it was one of the fastest-growing economies in Africa.

A commodity boom raises GDP. Whether it raises the state's ability to pay its debts is a separate question, and the answer is often no.

Two growth rates

The first clue is in the split. Strip out hydrocarbons and Senegal grew just 2.2% in 2025. In Q1 2025, when the headline read 12.1%, non-oil growth was 3.1%. Almost all of the acceleration came from a single offshore field, Sangomar, which began producing in June 2024 and pumped about 99,000 barrels a day in Q2 2026, plus LNG cargoes from the Greater Tortue Ahmeyim project it shares with Mauritania.

Look at the 2026 bars. Oil output has plateaued near capacity, so it no longer adds growth year after year. The ministry now expects 2.5% headline growth, below its roughly 3% estimate for the rest of the economy. The boom was a one-time step up in output, not a lasting increase in the growth rate, and Q2 2026 GDP was up just 0.1% on the previous quarter.

Why GDP isn't cash

GDP counts everything produced inside a country's borders, including oil that legally belongs to a foreign operator. In Q2 2026, Woodside's share of Sangomar's output was 86,000 of the field's 99,000 barrels a day. The Senegalese state, through its oil company Petrosen, taxes and royalties, receives a slice, and under typical production-sharing contracts much of that slice arrives only after the operator has recovered its development costs.

That is why the ratio that matters is interest as a share of revenue. Moody's puts Senegal's at 23.7%, up from 16.1% in 2023: almost a quarter of every franc the state collects goes to interest before any teacher is paid or road is built.

The hole in the ledger

The second problem is that, until recently, nobody knew how much Senegal owed. After President Bassirou Diomaye Faye took office in 2024, an audit of the previous administration's accounts found that debt and deficits had been badly under-reported. The previous government had put debt at about 74% of GDP at end-2023. The Court of Auditors found central-government debt of 99.7%. The IMF, counting more of the public sector plus arrears, puts end-2024 public debt at 132%.

The deficit tells the same story. The 2023 deficit was reported as 4.9% of GDP; the audited figure is 12.3%, and 2024 came in at 13.4%. The IMF froze its previous programme over the misreporting, and the new one requires "decisive corrective actions" before the Board can grant a waiver.

Hidden debt does damage twice. It inflates the stock directly, and it destroys the credibility a government needs to refinance. Senegal's Eurobonds now trade below 50 cents on the dollar, S&P rates it CC and Moody's Caa2. Moody's expects private creditors to take losses of 10–20%.

Ghana ran this play first

Ghana struck oil at the Jubilee field in 2010. In 2011 its economy grew 14%, one of the fastest rates in the world, and it became a favourite of Eurobond investors. Over the next decade debt climbed from 33% to 93% of GDP. By 2021 interest was eating almost half of government revenue. In December 2022, with inflation at 54% and the cedi having lost around half its value, Ghana suspended payments on most of its external debt.

The pattern is easy to miss while it's happening: a second burst of oil-driven growth in 2017 (8.1%) came with debt still rising. Growth was real, but it was not the kind that fills a treasury. Only restructuring and an IMF programme brought debt down, to an estimated 49% of GDP in 2025.

Zambia: the price of borrowing

Zambia's boom was copper, not oil. Riding high metal prices, it issued its first Eurobond in 2012, $750 million at a 5.4% coupon, which was oversubscribed. When copper turned and the kwacha fell 40% in 2015, each new bond cost more: 8.5% in 2014, 9% in 2015. Debt went from 62% of GDP in 2019 to 104% in 2020, and in November 2020 Zambia missed a $42.5 million coupon, the first African sovereign default of the pandemic. It then spent years in the G20 Common Framework working out a deal.

The CFA twist

Senegal differs from both in one important way. It uses the West African CFA franc, pegged to the euro and managed by a regional central bank, the BCEAO. Inflation was 1.2% in August, and there has been no currency collapse like the cedi's or the kwacha's.

That helps and hurts. Households are spared the inflation spiral that hit Ghana. But Senegal also loses the release valve of devaluation, which in Ghana and Zambia at least made exports cheaper. All of the adjustment has to come through the budget: higher taxes, lower spending, and continuous refinancing on the regional bond market, where much of the debt is short-dated.

About CFA 4.65 trillion (~$7.7bn) of regional debt matures by 2030, with yields above 8% at recent auctions. For comparison, the whole IMF programme is $2.2bn over three years.

What to watch

• The IMF Board vote on the $2.2bn ECF, which depends on a misreporting waiver and on financing assurances from creditors.
• Eurobond terms. About $4.8bn across five series is inside the treatment perimeter, with regional CFA debt and seven total-return swaps outside it. How large the haircut is will set the tone.
• The 2027 budget and revenue strategy. The new medium-term revenue strategy is the real test of whether the oil money reaches the treasury.
• Regional rollover. CFA 1.33 trillion falls due in 2027. Auction yields will show whether regional investors still have confidence.

The lesson from Ghana and Zambia is not that resource booms are bad. It is that a boom changes what lenders will lend much faster than it changes what the state collects. Senegal discovered its oil and its hidden debt at almost the same moment. The oil was the good news, but it was never going to pay for the debt.
