Occupy Wall Street debt buying 'useful'
15 November 2013 Last updated at 09:53 GMT
A group of Occupy Wall Street activists has spent $400,000 (£250,000) raised through donations buying up and cancelling Americans' personal debt.
By purchasing the debt on the secondary market at knockdown prices, the group has managed to cancel nearly $15m (£9.3m) of face-value debt - mostly unpaid medical bills.
Marcus Ashworth, head of fixed income at Espirito Santo Investment Bank, believes "it's a very clever idea".
He said: "If it stays on a relatively small scale, then it could be scalable and useful. However if it gets any form of real traction, unfortunately you'll get to realise the true cost."
