SAC Capital Advisors LP may curtail dealings with Deutsche Bank AG because the German lender pulled a credit line after the hedge-fund firm was accused of insider trading, the Wall Street Journal reported.

As part of a restructuring in the wake of the criminal case, SAC is examining its ties with some Wall Street banks that help finance and manage its trades, the newspaper wrote, citing unidentified people familiar with the matter. Deutsche Bank’s decision irritated SAC officials, and the prime-brokerage relationship is among those under review, the Journal said, citing people with knowledge of the companies’ talks.
