Probably not because their regulators are any smarter or scrupulous than those in the U.S. – more likely because they’re relatively powerless to conceal them. From Caroline Salas Gage and Joshua Zumbrun at Bloomberg:
The Federal Reserve Bank of New York was aware of potential issues involving Barclays Plc (BARC) and the London interbank offered rate after the financial crisis began in 2007, according to a statement from the district bank.
“In the context of our market monitoring following the onset of the financial crisis in late 2007, involving thousands of calls and e-mails with market participants over a period of many months, we received occasional anecdotal reports from Barclays of problems with Libor,” New York Fed spokeswoman Andrea Priest said in an e-mailed statement.
“In the spring of 2008, following the failure of Bear Stearns and shortly before the first media report on the subject, we made further inquiry of Barclays as to how Libor submissions were being conducted,” the statement said.
