The Central Bank of Nigeria (CBN) has banned nine deposit money banks (DMBs) from the foreign exchange market, for hiding over $2 billion belonging to Nigerian National Petroleum Corporation (NNPC) from the Treasury Single Account (TSA).

According to Channels TV, President Muhammadu Buhari has been briefed on the breach by the banks, and they have all been mandated to move the monies to the treasury single account.
: Diamond, UBA, Heritage, FBN, Fidelity, Skye, Sterling, Keystone and FCMB are all suspended from all FX markets for hiding, failure to remit NNPCg$2.12bn into government coffer. They will all be allowed to return to NGR FX market operations once they fully pay-up NNPC$2.1bn into TSA

Sources say President Buhari already briefed of nine (9) banks hiding of NNPCgro $2.1bn fund from TSA and sanctions imposed - ChannelsTV

Putting this in perspective, $2.1bn @ N320 N672bn. This is approx. 37.0% of the total N1.8tn earmarked for capital expenditure in 2016 budget and almost at par with the N691bn shared by the FAAC in July 2016. - Ayodeji

9 Banks hiding this huge amount of money that belongs to FG and someone said we should slow down on corruption. Buhari fire on.
My opinion

They hid $2.12b from TSA Maka why

The management of those banks just found themselves in hot soup...

When will these banks realize the need to follow rules and regulations instead of cutting corners to declare big profits at the expense of our wellbeing.

I think the entire management of those banks should be sacked and sued

Where are the bigoted wailers?

The CEOs of those banks need to be dealt with. They knew fully well what they were doing.

If the money hadn't been discovered they'd have just kept it. Thieves!
