"As interest rates go up, service charges on deposit accounts come under pressure," Mr. Armstrong said. Trust Growth Stymied Mortgage origination fees, mutual fund sales fees, and trading account commissions also came under pressure during the quarter, Mr. Armstrong said. Finally, growth in trust income, which produced 10% of the company's total revenue last year, has virtually ground to a halt due to the stock market decline. The main culprit: SunTrust has been losing some institutional clients disappointed by poor performance in the bank's individually managed trust accounts, which are supervised by well-known money manager Tony Gray, the chief executive of SunTrust's investment subsidiary in Orlando. "It's a reflection of institutional money's unwillingness to see a good manager through a tough time," said Ms. Bush, the analyst.
