Matthew Eastwick已经把他的背部转向了华尔街。经过15年以上与金融巨头在内的金融巨头，德意志银行集团和美林公司的德国银行集团，39岁的银行家正在将他的技能在公司债券竞技场，康涅狄格州斯坦福德（Stamford）based investment management firm with assets of $14.7 billion as of January 31. As head of its newly formed debt capital markets group, Eastwick wants to tap the surge in U.S. corporate debt issuance — which hit $411 billion in the first quarter of this year, nearly double the total in first-quarter 2008, according to Bloomberg — as U.S. companies seek alternative forms of long-term financing. “The level of activity has never been greater, and yet due to consolidation of the sector, there are fewer large banks out there doing the business,” he notes. Eastwick is just one in a wave of senior bankers who have walked away from Wall Street to help independent broker-dealers and investment firms develop institutional services that were almost exclusively the domain of bulge-bracket banks.
