Think of a number and multiply by eight

We haven’t had a good denominator post in a while, but I was struck by Stuff’s story on ‘social lending’.  By next April, an NZ company hopes to be able to start up peer-to-peer lending here, after changes in the law, and we’re told

“This will be a way for individuals to play alongside the big institutions,” Milsom said

Just how that can happen – and the scale that is possible – is shown from what has happened in the UK, where the largest peer-to-peer lender has lent more than £330 million since it launched in 2005.

That’s an average of just over £40 million per year over 2005-2012, or about 66p per capita per year in the UK.  On the same scale in New Zealand, that would come to perhaps $6 million per year in loans.  The UK lender in question appears to be Zopa, and they make their money by charging a 1% borrowing fee and 1% lending fee.  Under the same setup, $6 million per year in loans would mean $120 000 per year in income for an NZ equivalent, before paying any costs.

It’s certainty possible that peer-to-peer lending will take off, and it might not be long before it exceeds 1% of all unsecured consumer debt. But the idea makes more sense spun as ‘room for expansion’ not as ‘look at the scale in the UK’.
