Yes, it’s in The Guardian and it’s on economics. But it’s also rather good.
The one addition I would have made is to point out that Hayes was unimportant but bad. Sure, he fiddled Libor. But so were many others and the cumulative effect largely cancelled out.
The other fiddling, all the banks grossly under reporting in the crisis, was very important and good. Still fiddling of course, but who really would have wanted to see 14 day Libor being quoted as infinite?
