Hello, I'm Edward McBride, finance editor of The Economist, and this is Money Talks. This week we'll be talking to Simon Rubinovich about the economics of coups after a tumultuous week in Turkey.

The sun has estimated that is as much as a 2% decline in income per capita every year after the coup for well over a decade.

No one quite knows what those banks are getting up to.

I mean that is synonymous with a crisis.

We're now joined by Jonathan Rosenthal who's been looking at growing concerns about African banking.

Africa's banks have been placed under too much stress by the commodity crisis.

Oil-rich countries like Nigeria and Angola are seeing the economic ramifications of collapsing oil prices which have exposed weaknesses

in their banking systems.

Jonathan, first of all, how big a crisis are we talking about?

Well, that's the first thing that really

interested me and it's a question that I took to Alan Cameron he's an

economist at Exotics which is an investment bank that specializes in frontier

markets. I'm Alan Cameron and I'm an economist with Exotics focused on Africa.

Alan was one of the first prominent voices on African banking to call out Nigeria as being in a banking crisis.

Now that's something the Nigerians themselves have been denying and continue to deny. So I asked him what's going on there.

Well I think if you look at the sector, the biggest bank, the first Bank of Nigeria is showing us NPL that are about 18% as the last

results that they have reported.
