Is Treasury Bills Halal in Nigeria?

Treasury bills are the default yield instrument of Nigerian finance: banks hold them, fund managers anchor portfolios on them, and every money market fund quotes rates driven by them. The structure is simple enough to rule on in a sentence. An investor pays, say, 950,000 naira today and receives 1,000,000 at maturity; the 50,000 difference is the price of lending money to the government, fixed in advance at auction. A stipulated increase on a loan is riba, and the identity of the borrower, even a sovereign, has never been an exemption in fiqh.

The discount mechanics sometimes confuse retail investors into thinking no interest is involved because no coupon is paid. The fatwa analysis looks through the packaging: buying a debt claim for less than its face value and collecting the difference is precisely the discounting of debt the classical prohibition addresses. OMO bills and FGN savings bonds share the same character, an interest-bearing sovereign loan, differing only in tenor and distribution.

What makes Nigeria unusual, and makes this verdict practical rather than merely restrictive, is that the same government issues a certified alternative. FGN Sukuk, issued through the Debt Management Office since 2017, finance specific federal road projects using an Ijarah structure: sukuk holders own an interest in the financed assets and earn rental income from them, certified by Shariah advisers to the issuance. The distinction is structural, not cosmetic: T-bill income is the price of lent money, while sukuk income is rent from an identifiable asset. The repeated oversubscription of FGN Sukuk issues shows Nigerian investors have accepted the instrument at scale.

The practical portfolio question is honest to ask: T-bill yields sometimes exceed sukuk rental rates, and money market funds built on T-bills offer daily liquidity sukuk do not. The fatwa answer does not bend to yield: riba is prohibited at any rate, and a Muslim investor's fixed-income sleeve in Nigeria runs through sukuk, Shariah-compliant fixed income funds that hold sukuk, and non-interest bank deposits structured on Mudarabah. Several licensed Nigerian fund managers operate Shariah-compliant fixed income and money market alternatives, so the category exists, with the usual diligence on each fund's actual holdings.

For holders of existing T-bills, the separation rule applies: principal is lawful, and the discount gain is interest, which the purification guidance directs to charity. Exiting at maturity rather than rolling over ends the exposure cleanly. Fund investors should check what their money market fund holds; a fund whose portfolio is T-bills and bank placements is an interest vehicle regardless of its own branding.

One more distinction matters for completeness: holding T-bills is different from working in institutions that trade them, a question the employment fatwa literature treats separately with its own hierarchy of directness. This verdict addresses the investment.
