The Economist reports that regulation catches up with peer-to-peer lending:

Meanwhile, a case working its way through the courts may subject P2P loans to state usury laws, from which banks with a national charter are exempt. That would prevent the P2P firms from lending to the riskiest borrowers in much of America. In addition, the Consumer Financial Protection Bureau, a federal agency, announced this month that it would begin accepting complaints about P2P consumer lending.

Rates of delinquency are rising as well.
