It began as a murmur in the National Assembly, amplified by viral commentary: in terms of reach and reliability, certain fintech platforms have quietly become the most central banks in Nigeria’s informal economy. No one can dispute the facts: where outages crippled traditional banks on Marina, these digital operators—backed heavily by foreign capital—kept the wheels of commerce turning for the tailor, the artisan, and the market woman. This success in achieving financial inclusion deserves applause.

However, a success story does not exempt the infrastructure from strategic scrutiny. When a non-indigenous entity becomes the effective custodian of over 50 million users and trillions of naira in monthly transactions, we are no longer discussing mere technology; we are discussing national critical infrastructure.

The heart of the concern is not hostility toward foreign investment, which remains vital for growth. The concern is one of strategic dependence and data sovereignty. Data, we are constantly reminded, is the new oil. By controlling the payment rails, a foreign-led platform gains the ability to map the economic heartbeat of Nigeria—knowing who pays whom, where the money clusters, and the granular details of consumer behaviour.

This is why, globally, countries are increasingly treating data governance as a matter of national security. When U.S. authorities compelled the Chinese firm Beijing Kunlun Tech to divest from the data-intensive social app Grindr, it was a clear signal: any platform that reaches systemic or strategic scale, regardless of its sector, becomes a vulnerability if its control room is subject to the influence of a foreign state apparatus.

If a social app is deemed a threat due to access to location and personal data, what regulatory safeguards must apply to applications that may process highly sensitive financial identifiers, including BVN-linked data.

We cannot celebrate the efficiency of these digital wallets while ignoring the strategic implications of their origins.

Analysts worldwide, including at the Carnegie Endowment, have argued that in some jurisdictions the lines between private technology firms and state objectives can become blurred—a pattern seen from Huawei to TikTok. To assume Nigeria is somehow immune to these geopolitical realities is not confidence; it is dangerous oversight.

The pertinent question is one of contingency and control: have we inadvertently handed the keys to our economic kingdom to a landlord we do not fully understand? Should a geopolitical dispute arise between Nigeria and the home country of the majority shareholder, can a switch be flipped in a server room thousands of miles away, instantly crippling our informal economy?

This is not an accusation of intent or conduct; it is a question of risk management that every sovereign nation must ask.

This moment demands that the Central Bank of Nigeria (CBN) and our security agencies look beyond the critical, but singular, metric of financial inclusion. The time has come to scrutinize the potential for national exclusion—the risk of being locked out of our own economic data—if control is compromised.

We need a regulatory framework that is non-confrontational yet absolute in its insistence on data sovereignty. This includes mandating full transparency around data storage and access controls, and potentially requiring that strategic financial data be hosted locally, inaccessible to foreign state entities.

The speed and convenience of the digital wallet are welcome, but responsible stewardship demands that innovation never outpace governance. Nigeria must ensure that the extraction, storage, and refining of its economic data—its new oil—serves national interests first. Asking these questions is not an act of hostility to the foreign capital that powers these platforms; it is the ultimate act of self-defense for a digitally deepening nation.
