Nigeria’s $5bn Swap Deal Faces Fresh Fitch Warning Over Debt Risks

Nigeria’s $5 billion financing arrangement with First Abu Dhabi Bank has come under renewed scrutiny after Fitch Ratings warned that the growing use of Total Return Swaps by emerging-market governments can create transparency, liquidity and creditor-recovery risks.

The latest warning was contained in a Fitch report published on September 14, 2026, titled Sovereign Total Return Swaps and Repo Transactions: Q&A 2026. The report examined the use of these financing structures by sovereign borrowers, including Nigeria, Angola, Senegal, Colombia and Argentina.

The development comes several months after Nigeria secured legislative approval for a Total Return Swap, or TRS, programme of up to $5 billion with First Abu Dhabi Bank, the United Arab Emirates-based lender.

Nigeria has already drawn the first $1.5 billion tranche from the arrangement. Finance Minister and Coordinating Minister of the Economy Taiwo Oyedele confirmed the drawdown in June, saying the financing would be used for infrastructure, budget implementation and refinancing more expensive debt.

What is Nigeria’s $5bn Total Return Swap?

A Total Return Swap is a financial derivative that can allow a government to obtain hard-currency financing while using government securities as collateral.

In Nigeria’s case, the arrangement involves naira-denominated Federal Government securities. The Debt Management Office said in an August 2026 FAQ that the facility has a maximum size of $5 billion and a six-year tenor. The collateral is valued at 133.3 percent of the amount drawn.

The National Assembly approved the $5 billion programme on March 31 as part of a wider $6 billion external borrowing request. The government said the financing would support fiscal needs, infrastructure and the refinancing of existing obligations.

The government has argued that the arrangement provides another source of foreign-currency funding at a time when borrowing through conventional international markets can be expensive.

Why Fitch is concerned

Fitch does not dispute that Total Return Swaps can provide governments with access to liquidity and diversify their funding sources.

The agency’s concern is what can happen when such instruments are used during periods of financial stress.

According to Fitch, the contractual terms of some sovereign TRS arrangements are only partly disclosed. That can make it harder for investors, legislators and other market participants to determine the full scale and cost of a government’s obligations.

The agency identified three broad areas of risk: transparency, liquidity management and creditor recovery.

The liquidity issue is particularly relevant when the collateral consists of domestic government bonds.

If the market value of those bonds falls, a government may face additional collateral requirements or other contractual consequences at a time when financial conditions are already under pressure. Fitch noted that this creates a potentially procyclical feature in such arrangements.

For Nigeria, the currency mismatch is also significant. The financing provides hard-currency liquidity while the collateral is denominated in naira. A sharp fall in the value of the collateral could therefore create additional foreign-exchange pressure if dollar payments or margin requirements become due.

The debt-restructuring question

Fitch also highlighted an issue that extends beyond the immediate cost of the financing.

If a sovereign eventually has to restructure its debt, creditors backed by collateral may have a different recovery position from conventional unsecured bondholders.

The rating agency said TRS lenders may be able to recover some or all of their exposure through pledged collateral rather than participating in restructuring negotiations in the same way as unsecured creditors. That could alter how losses are distributed in a future restructuring.

Fitch also noted that there is limited precedent for determining exactly how these instruments would behave in sovereign debt restructurings.

That uncertainty is one reason the structure has attracted attention from international financial institutions.

IMF has also raised concerns

The International Monetary Fund previously warned Nigeria about the risks associated with the transaction.

During its 2026 Article IV consultation, the IMF highlighted concerns surrounding complex financing instruments and called for stronger transparency and fiscal-risk management. Its staff report also noted that Nigeria’s authorities were aware of the margin-call risks associated with the $5 billion Total Return Swap.

In June, IMF Nigeria representative Christian Ebeke said derivative-based financing structures could be opaque and that their terms were not always sufficiently transparent when similar instruments were reviewed across countries.

The IMF and Fitch therefore share concerns about the complexity and potential risks of sovereign swap financing, although their treatment of the collateral differs.

Fitch and IMF treat the debt differently

One important distinction is how the two institutions account for the securities pledged under a TRS.

Fitch generally treats pledged bond collateral as a contingent liability rather than immediately counting the full collateral value as debt. The IMF takes a more conservative approach when sovereign-issued bonds are used as collateral and treats the transaction as involving a transfer of ownership, meaning the full value of the pledged securities can be reflected in its assessment of debt.

This difference does not mean that either institution is saying Nigeria has hidden or illegal debt.

Rather, it reflects different accounting and analytical approaches to a relatively complex financing structure.

What the Nigerian government says

Nigeria’s Debt Management Office has defended the arrangement and provided additional information about its structure.

In an FAQ published on August 28, the DMO said that no oil revenue or strategic national assets had been pledged as collateral. Instead, the transaction is secured by eligible naira-denominated Federal Government securities.

The DMO said the collateral is valued at 133.3 percent of the amount drawn and that the facility is subject to monthly margining, with a five-business-day period to address a shortfall in the required collateral level.

The clarification followed public discussion about the nature of the arrangement and what assets Nigeria had committed under the deal.

Why the financing matters to Nigeria

The government is using the facility within a broader debt-management strategy.

Nigeria’s 2026 IMF Article IV report says the authorities’ debt-management strategy aims to diversify financing sources while managing costs and risks. The report projects Nigeria’s external debt to rise to $119.3 billion in 2026, compared with $109.3 billion in 2025, under the IMF’s projections.

The government has said the swap proceeds can be used to refinance more expensive obligations and support infrastructure and budget implementation. Oyedele said the first $1.5 billion drawdown was being made in phases to help manage borrowing costs.

The arrangement therefore gives Nigeria another avenue for accessing foreign currency without relying exclusively on conventional Eurobond issuance.

But the cost and risk of that flexibility depend on the full contractual terms, collateral requirements, market conditions and the government’s ability to meet its obligations if those conditions deteriorate.

What to watch next

The key issue is no longer simply whether Nigeria can access the financing.

Attention will increasingly centre on how the facility performs as further tranches are drawn and how the government manages the collateral and associated foreign-currency obligations.

Several developments will be particularly important:

• Whether Nigeria draws additional amounts from the $5 billion facility.
• How the naira and domestic government-bond prices perform.
• Whether collateral requirements create additional dollar liquidity demands.
• How much the government ultimately pays for the financing compared with conventional borrowing.
• How the proceeds are allocated between debt refinancing, infrastructure and budget financing.
• Whether more details of the contractual arrangements become publicly available.
• How rating agencies and international financial institutions assess the facility as it develops.

For now, Fitch’s message is focused on risk management rather than a prediction of failure. The agency recognises that TRS arrangements can provide funding flexibility and liquidity, but warns that their complexity can create additional vulnerabilities if transparency, collateral requirements and restructuring implications are not carefully managed.

Nigeria’s $5 billion arrangement has therefore moved beyond being simply another borrowing programme. It is also becoming a test of how an emerging-market government can use increasingly sophisticated financial instruments while maintaining clear public debt reporting, adequate liquidity protection and confidence among creditors.
