'US Treasury Secretary sent memo in 2008 to Mervyn King to improve Libor'

The Wall Street Journal have reported that Timothy Geithner, former president of the Federal Reserve Bank in New York sent a private memo to Bank of England Governor Mervyn King in 2008, calling for six changes that he said would improve the integrity of the Libor rate.

The latest disclosure makes clear that Federal officials were aware of irregularities in the Libor interest-rate market. The Geithner recommendations, which came in a June 1, 2008, memo, included a call to "eliminate incentive to misreport" by banks.

More documents are due to be released later today by the Federal Reserve Bank of New York, in response to demands by lawmakers for more information about Mr. Geithner's and the New York Fed's efforts to address questions about Libor.
