Jon Hilsenrath of WSJ provides an illuminating account of how Daniel Tarullo as head of the Large Institution Supervision Coordination Committee has changed the way bank supervision and rules are set for U.S. banks since the days of the 2008 financial crisis. Tarullo started the effort under Ben Bernanke and continues this in 2014-2015 under Fed chairwoman Janet Yellen. The New York Fed is seen as ineffective in bank supervision and the supervisory role is now entirely performed under the leadership of Tarullo, assisted by Kenneth Gibson and Timothy Clark. The trio are some of the great unsung heroes of the effort to put the U.S. financial system and the economy on a safer footing.
