On October 20, 2015, SEC Chair Mary Jo White gave the keynote address at the “Evolving Structure of the U.S. Treasury Market” conference organized by the U.S. Department of Treasury and the Federal Reserve Bank of New York. The conference and speech follow this summer’s Joint Staff Report analyzing the significant volatility that the U.S. Treasury market experienced on October 15, 2014. The Joint Staff Report was a cooperative effort of the Department of Treasury, the Federal Reserve, the SEC and CFTC, and was the subject of a previous post on this blog (Regulators Fail To Identify Cause Of Abnormal US Treasury Trading on October 15, 2014).
