About Mmiri

What is Mmiri?

Mmiri (pronounced mm-ee-ree) is the Igbo word for water — something essential, always moving, and available to everyone. That is exactly what we want Mmiri.ng to be: an essential, always-updated source of financial information for Nigerians, freely available to all.

We track the live parallel market exchange rate (the black market / aboki rate) alongside the CBN official rate, so you always know exactly what your naira is worth — and how big the gap between the two markets is.

Why we built this

Every Nigerian knows the struggle: the official rate says one thing, the street says another, and finding an up-to-date, trustworthy number is harder than it should be. Most rate sites are cluttered, slow, or stuck behind paywalls.

Mmiri is fast, clean, and free. No sign-up, no paywall, no ads cluttering the rates. Just the numbers you need, presented clearly.

Data sources

We source our data from publicly available information and aggregate it to give you the most accurate picture possible:
