Fitch Ratings has cautioned that Nigeria's planned $5 billion Total Return Swap (TRS) with First Abu Dhabi Bank could mask the country's true debt profile and create significant hurdles in any future sovereign debt restructuring.
The warning, contained in a Fitch report titled *Emerging Market Sovereigns' Use of Total Return Swaps Raises Risks*, comes months after the Nigerian Senate approved the transaction in April 2026 to refinance expensive debt and fund critical infrastructure. The facility is expected to mature in 2032 and would involve pledging N6.67 billion worth of local-currency bonds as collateral in exchange for hard-currency liquidity.
Fitch acknowledged that TRS arrangements can provide cheaper financing and broaden funding options for sovereigns with constrained market access. However, it emphasised that the derivative structure carries significant transparency and liquidity risks.
"Margin calls payable in U.S. dollars against naira-denominated collateral could intensify liquidity pressures if domestic yields rise or the naira weakens," Fitch said in the report seen by Nairametrics.
The agency warned that because TRS transactions are structured as derivatives, they may not always be recorded as conventional public debt. Limited disclosure of their terms could raise governance concerns and obscure the true scale of sovereign borrowing.
Fitch said material gaps in transparency could weigh on its Issuer Default Rating assessment, particularly where terms include margin calls or early termination clauses that may be triggered during financial stress. If the government cannot repay the financing in cash upon termination, the development could constitute a default under Fitch's sovereign rating criteria.
Nigeria's proposed deal follows similar transactions in Angola and Senegal, though Fitch noted the countries adopted the structure under different circumstances. Angola's earlier TRS transactions highlighted the risk of margin calls forcing the government to draw from reserves, while Senegal's deals were driven by efforts to secure cheaper financing than prevailing Eurobond yields.
The warning from Fitch echoes a similar caution issued by the International Monetary Fund earlier in June 2026. The IMF flagged that derivatives-based sovereign financing arrangements can be difficult to assess and may expose participating countries to significant fiscal and liquidity risks, especially where repayment obligations are tied to market movements or exchange-rate changes.
Fitch also noted that while Nigeria's $5 billion exposure is significant, the risk could escalate if TRS financing grows as a proportion of the country's total external debt. The dual warnings from Fitch and the IMF underscore concerns that although the deal could provide cheaper hard-currency liquidity, its structure may introduce additional debt, transparency, and refinancing risks for Nigerian taxpayers and businesses.
