On Monday, Federal Reserve Chair, Janet Yellen, issued a letter to inform the senior House Republicans that her June meeting with a financial analyst had no links to the October leak of confidential interest-rate information in 2012.

Yellen said that she met the analyst, Regina Schleiger of Medley Global Advisors, on June 11, 2012, to discuss general financial matters. This meeting was several months before Medley's revelation of October 3, the day Medley informed the clients about the consensus reached by the Fed policymakers on launching of an additional round of bond purchases, to stimulate economic growth.

Yellen explained in her letter, "Nothing Medley Global Advisors reported in October about the events of the September 2012 and let me assure you that in any case, I did not convey any confidential information".

The senior House Republicans are investigating whether market-sensitive information was deliberately leaked from the Fed's interest-rate policy meeting, in September 2012.

The possible 'leak' was cited by Rep. Jeb Hensarling, a Texas Republican who heads the Financial Services Committee and is a prominent critic of the Fed. He has accused that the Fed's internal probe had been dropped earlier at the request of several members of the Fed's policymaking body.

The lawmakers had requested the names of Fed officials and staff that had contact with the analyst's firm, Medley Global Advisors, from June through October 2012.

The Fed's also initiated an internal probe that begun in October 2012, at the request of then Fed Chairman Ben Bernanke and was completed in March 2013. The probe was handled by the Fed's Inspector General and the Justice Department.

In its own investigation, Fed found no evidence that confidential information was deliberately leaked from September 2012 policy meeting.

Fed told the committee that 'any disclosure of information on Fed policymakers' views, appear to have been "unintentional or careless" and did not contain details of policy proposals'.
