Global ratings agency Fitch Ratings has raised concerns over Nigeria’s proposed $5 billion Total Return Swap (TRS) arrangement with First Abu Dhabi Bank, warning that the structure could expose the country to heightened debt vulnerabilities, currency pressures, and reduced fiscal transparency.

The warning follows a similar caution from the International Monetary Fund (IMF), which has urged Nigeria to tread carefully with complex derivative-based financing models, noting that such instruments have often proven opaque and difficult to manage in emerging markets.

The Total Return Swap is a derivative financing arrangement that allows Nigeria to obtain immediate U.S. dollar liquidity by transferring exposure to the performance and risk of underlying domestic assets, primarily naira-denominated government bonds.

Under the proposed structure, First Abu Dhabi Bank would provide $5 billion in funding disbursed in tranches over several years. In return, Nigeria would pledge naira-denominated government bonds valued at approximately $6.67 billion as collateral.

The financing would be priced at the Secured Overnight Financing Rate (SOFR) plus 3.95% for initial drawings, rising slightly to 4.0% for subsequent tranches. It includes a three-year grace period, a six-year operational timeframe, and a maturity profile extending toward 2032, alongside a break clause allowing for early renegotiation of terms.

Fitch and the IMF both flagged the risk of margin calls, which could be triggered if Nigeria’s macroeconomic conditions deteriorate.

According to Fitch, a sharp depreciation of the naira or a rise in domestic bond yields could reduce the value of the pledged collateral, forcing Nigeria to post additional U.S. dollar liquidity to maintain the arrangement.

The agency warned that such obligations could arise during periods of financial stress, potentially intensifying pressure on the country’s foreign exchange reserves at a time when liquidity may already be constrained.

Fitch stated that “margin calls payable in U.S. dollars against naira-denominated collateral could generate hard-currency pressure if domestic yields rise or the naira weakens.”

Beyond liquidity risks, Fitch also raised concerns about the accounting treatment of the transaction. Because Total Return Swaps are often recorded as contingent liabilities rather than direct public debt, they may not fully appear in official debt statistics.

This, the agency warned, could obscure the true level of sovereign exposure and weaken transparency in public finance reporting. It also noted that contractual details and trigger conditions are often only partially disclosed, limiting the ability of investors to fully assess the risks involved.

The IMF echoed these concerns. Its resident representative in Nigeria, Christian Ebeke, said the country’s recent return to international capital markets should encourage the use of more transparent and conventional financing options, such as Eurobond issuance or concessional lending from multilateral institutions.

Despite the warnings, analysts say Nigeria’s consideration of alternative financing structures reflects ongoing fiscal pressure, including a widening budget deficit and elevated borrowing costs in traditional debt markets.

While the swap arrangement may provide short-term liquidity relief, financial experts caution that it introduces complex obligations that could complicate long-term debt sustainability.

With Nigeria’s debt profile already under close scrutiny, the proposed transaction has intensified calls for greater public disclosure and stronger risk management frameworks.

How the government navigates the risks associated with the derivative structure—particularly in volatile currency conditions—may prove critical to investor confidence and the country’s sovereign credit outlook in the years ahead.
