Securities dealers are losing their grip on short-term investment  management for corporations, a study shows. 
The study, conducted by Chicago-based Treasury Strategies Inc., found  that securities dealers hold 53% of the market, down from 63% last year.   Banks' share, meanwhile, has held steady at 23%, while that of investment   managers has climbed to 10% from 4%.     
  
The study was based on corporate liquidity management practices at 496  U.S. asset management clients. Companies participating in the survey all   had annual revenues exceeding $50 million.   
Anthony J. Carfang, partner at Treasury Strategies, said the rapidly  expanding economy means many companies have unexpectedly high levels of   operating cash. He placed the total corporate liquidity market at about   $300 billion.     
  
Because banks have ready access to the payment system and offer  convenient ways to move funds, they may be best positioned to take   advantage of the growth in investing.   
"Convenience is a factor," Mr. Carfang said. "If the banks can make  investing automated and convenient, and all money begins in a bank account,   then banks have an opportunity to preempt securities dealers."   
Corporations increasingly invest in money market mutual funds, sweep  accounts, government securities, and repurchase agreements, and less in   commercial paper, the survey showed.   
  
Mr. Carfang said he was surprised to find that about 35% of operating  cash investments were managed by executives who spent less than 25 hours a   month deciding where to place them.   
"Some treasurers have decided to relegate investments to a lower level,"  Mr. Carfang said. "They are also putting corporate investors on a real   short leash by saying, 'You can buy Treasuries, and you can only invest   overnight,' so there's no way to screw up."     
Securities dealers may "still have a commanding share," Mr. Carfang  said, but banks are making inroads by linking cash management and demand   deposit services with investment products, enabling a bank to automate   investing.     
James Graham, executive vice president at PNC Bank Corp., Pittsburgh,  said corporations may favor the banking industry's approach to managing   corporate assets.   
  
"We try to provide convenience for the customers," he said, adding that  just a few short years ago, "banks were more focused on providing cash flow   services, but they were not making it really easy to make that investment   decision."     
Michael J. Rosenberg, vice president at Chase Manhattan Corp., said his  bank this year has doubled the attention it devotes to corporate liquidity   and investment management products.   
He said improvements in the technology for serving asset management  clients have brought more business to banks. 
"We made it extremely easy for corporations to work with us," said Mr.  Rosenberg. "The technology is so advanced now that the investment process   is down to a science."   
Mr. Carfang said he sees more corporations looking to invest in mutual  funds than in past years. 
"I think the fund companies are doing a nice job of getting in front of  a corporate treasurer and telling their story," he said.
