Some trust departments at national banks may be taking  too much risk when investing fiduciary funds in derivatives, a top   regulator warned Wednesday.   
Douglas E. Harris, senior deputy comptroller for capital markets, said  the Comptroller's Office is putting the finishing touches on a bulletin to   national banks about trust departments' use of derivatives.   
  
"We have uncovered some situations where national banks acting as  fiduciaries may not have had the kind of robust risk management processes   that we wanted to see," said Mr. Harris in an interview after a speech to   an End-Users of Derivatives Association conference here.     
Mr. Harris said that a number of national bank trust departments have  not been following the OCC's banking circular 277 - guidelines issued in   1993 for managing the credit risks of derivatives transactions.   
  
"Some of our banks were missing the fact that banking circular 277 was  applicable to their actions as fiduciaries," Mr. Harris said. The circular   also recommended that national banks assess whether a particular derivative   transaction is appropriate for a customer.     
The upcoming bulletin, which may be sent as early as next week, will  recommend that national banks determine whether derivatives are appropriate   investments for specific fiduciary accounts.   
National banks will also be warned about investing money from different  fiduciary accounts in a single derivative instrument, Mr. Harris said. 
  
"We will caution banks about the potentially increased market and  liquidity risk resulting from such a practice," he said. 
The bulletin was prompted in part by a letter the OCC received from  Olena Berg, assistant secretary for welfare benefits at the Labor   Department. The March 21 letter outlined how derivatives should be used in   managing pension plan portfolios.     
"We determined that this was an opportune time to set forth our  expectations concerning risk management of derivatives and mortgage-backed   securities transactions in a bulletin specifically targeted at national   bank trust departments," Mr. Harris said.     
In his speech to the conference, Mr. Harris noted that the banking  agencies are close to publishing a proposed rule governing banks' sales of   government securities. The proposal is expected to be similar to a recent   one from the Securities and Exchange Commission.
