ST. LOUIS/WASHINGTON (Reuters) – Clashes over strategy within JPMorgan Chase & Co’s compliance operations have led to the departure of a series of managers in the past year, according to three of those who have left. Faced with intense scrutiny after regulators found failings in its anti-money laundering (AML) program, and rising costs as it seeks to identify suspicious transactions, the biggest U.S. bank has invested in new automated systems and installed executives skilled in making bank operations more efficient.
