Warsh played a significant role in navigating the financial market turmoil of 2007 and 2008. According to author David Wessel, "Warsh established himself as the chairman's protector in Republican circles and Bernanke's bridge to Wall Street chief executives." Bernanke would write "Don Kohn, my vice chairman, with his long experience at the Fed, and Kevin Warsh, with his many Wall Street and political contacts and his knowledge of practical finance, were my most frequent companions on the endless conference calls through which we shaped our crisis-fighting strategy."
