The Office of the Comptroller of the Currency on Monday  advised national banks to institute risk management systems for credit   derivatives, a new breed of instruments designed to reduce a bank's   exposure to loan concentration risk.     
In a bulletin issued to national banks, the OCC said credit derivatives  offer substantial risk management benefits but must be treated with the   same care as any other hedging instrument. That means banks should install   systems to monitor and control risks stemming from these instruments. For   example, the guidelines recommended that credit derivatives activities be   reviewed by bank employees not directly involved in the transactions.         
  
Blythe Masters, global head of credit derivatives for J.P. Morgan,  called the OCC's approach "very encouraging." 
"The absence of any regulatory discussion whatsoever has been a  constraint on the short-term growth of credit derivatives," Ms. Masters   said. "Had any initial statement from the regulators been overly   conservative, we would have been concerned that the growth of this product   would have been stymied.       
  
"The OCC has made the regulatory environment a much friendlier place,"  she added. 
The Federal Deposit Insurance Corp. and the Federal Reserve are expected  to issue similar guidelines soon. Michael Brosnan, acting senior deputy   comptroller for capital markets, said that regulators are holding off with   capital rules for credit derivatives in order to give the market a chance   to develop. The agencies acted because bankers and examiners are   increasingly asking about credit derivatives, he said.         
"We felt it was necessary to inform banks as to what credit derivatives  are, and what the supervisory issues are," Mr. Brosnan said in an interview   Monday. "For banks to hedge most efficiently, they need to understand what   kind of risks stem from their portfolio, and then how credit derivatives   fit into those risks."       
  
Experts say the current size of the credit derivatives market is about  $50 billion, but they estimate that figure may balloon to $1 trillion in   the next five years.   
Credit derivatives allow a bank to transfer credit risk, but not the  assets themselves, to a second institution. The contract requires the   second bank to compensate the original bank if the value of the portfolio   falls. In return, the original bank agrees to pay the second bank if the   portfolio increases in value.
