How Nigeria Controls Its Economy Through Banks, and Why It Fails

Controlling an economy through banks is like controlling water through a colander. It goes somewhere else.

Nigeria has a problem. Too much money. Inflation is getting out of hand. The Naira weakens against the dollar. Normal: central bank raises rates, waits, inflation drops. That takes time. Nigeria's government was impatient.

So Nigeria tried something different. They imposed strict controls on the banking sector. Restrictions on how much you could withdraw from the bank. Limits on how much you could exchange to dollars. Rules to prevent capital flight.

It was an attempt to steer the economy from above. With one lever, the banking sector, Nigeria thought it could say: money goes this way, not another.

What happened? The money disappeared.

Not disappeared as lost. Disappeared as in: moved to underground markets. Street traders. Informal money changers. Cash trading. Cryptocurrency. Everything that was away from official banks.

Nigeria's formal economy, already weak, saw trading volume decline. Small businesses could no longer work with each other financially. Employees could no longer receive their salaries through normal channels. Everything became cash, everything went underground.

What should Nigeria have done? What any country trying to fight inflation should do: stable, predictable interest rates. Clear regulation. Openness. Say: we raise rates until inflation comes down, that takes six months, here are your options.

What Nigeria did: look up, slam all doors shut, hope nobody can escape.

I recognize this pattern everywhere governments try to control economies. The Soviet Union tried to control food production. Consequences: black markets, starvation, collectivization that produced nothing.

Venezuela tried to control prices. Consequence: everything disappeared from store shelves, went underground.

Argentina tried to control currency exchange. Consequence: all trading went to parallel markets, peso lost value three times faster than officially.

The lesson is simple: you cannot steer an economy if you do not allow it to grow. You cannot push money back if the pushback is larger than the money.

Nigeria should have accepted: inflation is a problem you solve through rates and patience. Not through bans. Bans only work if you are willing to say: whoever breaks the ban, I punish relentlessly. And no government can do that at scale.

So what you see: official system breaks, informal economy grows, banks become political tools instead of sources of financing, and ordinary people become less prosperous because they have no trading channel anymore.

This is why states that intervene in economies usually make them worse. Not always. Sometimes government intervention is needed. But intervention must be careful, and honest, and with clear outcomes. Not: let's ban everything and see what happens.

Because what happens: your economy fragments.
