Romans crunched too but how did they uncrunch?

A supernumeracy fellow at Wolfson College, Philip Kay, has discovered history's first credit crunch and it happened to... you guessed it... the Romans, reported The Guardian today. Trouble is Kay knows why the crunch happened but doesn't know how they got out of it. Don't get me wrong, history is important and all, but if we have to look back to 66BC to sort out our current little pickle then we are definitely doomed.
