“In a report published in March by the Bank for International Settlements, economists Jacob Gyntelberg and Philip Wooldridge raised concerns that banks might report incorrect rate information. The report said that banks might have an incentive to provide false rates to profit from derivatives transactions. The report said that although the practice of throwing out the lowest and highest groups of quotes is likely to curb manipulation, Libor rates can still “be manipulated if contributor banks collude or if a sufficient number change their behaviour.”

Comment:

Libor stands for the London Interbank Offering Rate. It is the interest rate at which banks agree to lend to each other over various time periods, including overnight, three months and 12 months.

The post at Naked Capitalism is concerned about Libor being unreliable because of banks understating the rates they are paying (to conceal their desperation). The rate is an estimate set at the HQ of the British Bankers’ Association at 11 a.m. every morning in London on the basis of offers from 16 member bankers. The possibility exists that it could be manipulated.
