Adaeze didn't know what "dry posting" meant. She still doesn't. But she knows what it feels like to have her account frozen without warning, to stand at a PoS terminal and watch a transaction fail, and to be told by a bank customer service rep that "the issue is being resolved."

She is not one of the 176 affected account holders in the NIBSS ₦13.66 billion glitch case. But she could be.

Because the infrastructure that failed in September 2024 is the same infrastructure millions of Nigerians like her use every single day, and nobody is talking about what that really means.

The Number Nobody Is Putting Side by Side

Here is what we know, in 2024, electronic payment transactions in Nigeria hit ₦1.07 quadrillion, the first time in the country's financial history that figure crossed the quadrillion mark, according to NIBSS data.

That is over 11 billion individual transactions processed through the NIP platform in a single year. In that same year, on September 6th, a technical fault on that same platform sent ₦13.66 billion into accounts that were never meant to receive it.

NIBSS has now gone to the Federal High Court in Lagos, nearly 20 months later, to attempt recovery.

The headline coverage has focused on the how: how a "dry posting" fault works, how many banks were affected, how long the case has dragged. But the more uncomfortable question is the one most articles sidestep entirely.

If the infrastructure processed over a quadrillion naira without breaking, why did it now start and keep breaking? And at what point does a pattern of incidents stop being described as isolated?

A Pattern That Has Earned Its Name

This is not Nigeria's first encounter with nine-figure banking system failures, and the timeline does not flatter anyone. In 2023, a NIBSS-related issue reportedly worsened a ₦21 billion Flutterwave incident.

In 2024, GTBank mistakenly credited customers ₦1.9 billion after a separate technical problem. In 2025, Wema, Keystone, and Union Bank all experienced system failures tied to unauthorized transfers worth billions.

And this month, NIBSS itself went down again, disrupting transfers nationwide, with fintechs like LemFi and Carbon caught in the fallout.

Each incident arrives with its own press statement, its own unique technical explanation, its own promise of resolution. What they share is the pattern: the infrastructure processes more volume every year, and the errors become more expensive every year.

Behind many of these failures are rushed upgrades, weak third-party integrations, and systems that were not designed to carry the weight now placed on them.

The People This Actually Hits

The formal conversation around this NIBSS case is about recovery of funds, court orders, and account restrictions. But there is an entirely different conversation that never makes it into financial sector briefings.

Nigeria's informal economy, traders, artisans, market women, small business owners, has been pushed steadily toward digital banking by CBN cashless policy, ATM cash scarcity, and the basic reality that PoS is now how you survive in this economy.

Many of these people do not understand what a settlement system is. They do not know what NIP stands for. What they know is that their transfer did not go through, their account is acting strange, or their money is somewhere it shouldn't be.

Cases like the NIBSS ₦13.66 billion glitch may feel distant and institutional. They are not. When accounts get frozen as collateral damage in a recovery process, when Post No Debit restrictions land on the wrong accounts, when errors in the system create weeks of unresolved complaints, it is ordinary Nigerians absorbing the cost.

The most vulnerable and financially uninitiated users are not equipped to fight a system they were barely given time to understand before being asked to depend on it.

The Real Question This Case Raises

NIBSS will likely recover some portion of the ₦13.66 billion. The courts will likely grant some of the requested orders. A number of the affected accounts still hold traceable funds. But twenty months is a long time, and every day that passed between the glitch and the court filing was a day accounts remained accessible and funds moved further from recovery.

The more important question is structural: is Nigeria's payment infrastructure actively evolving to match the scale of transactions it is now responsible for, or is it growing in volume while the tolerance for failure stays stuck in an earlier and more quiet era?

Because ₦1.07 quadrillion is not a number that allows for the luxury of occasional system-wide errors. At that scale, even a fraction of a percentage point in failure rates translates into hundreds of billions of naira at risk.

The people who built this system know that. What is less clear is whether the investment in reliability is keeping pace with the investment in reach because Adaeze is still sending transfers and hoping they land. Most Nigerians are.
