WASHINGTON - Bankers will find it more expensive to overdraw their  Fed Wire accounts under a fee schedule approved Wednesday by the Federal   Reserve Board.   
The Fed voted unanimously to raise overdraft fees from an annual rate of  10 cents per $100 of overdrafts to 15 cents per $100. The move, effective   April 13, should cost the industry $9 million.   
  
The vote cuts the fee schedule approved in September 1992. Under that  plan, overdraft fees were to rise to 20 cents per $100 in April 1995 and to   25 cents in April 1996.   
Instead, the Fed said the overdraft fee will remain at the 15- cent  level for at least two years. The delay will give bankers more time to   improve their systems, the Fed staff said.   
  
It also should ease fears that financial institutions will move away  from Fed Wire to other wire transfer systems that charge less. 
The staff added that it feared that if one of these private systems  could not settle accounts, systemic failures would follow. 
The governors apparently were concerned with the loss of Fed Wire  business as well. Fed Chairman Alan Greenspan asked the staff if the 10-   cent fee had already caused banks to flee the Fed Wire. The staff said it   had not found any evidence of that.     
  
Overdrafts occur frequently during the 10 hours a day that the Fed Wire  is open. Fed officials said bankers, who move $900 billion in commercial,   repurchase, and other transactions a day over the system, often find it   impossible to manage their balances.     
This trouble was causing the Fed to extend $70 billion worth of credit a  day to Fed Wire users. 
This massive, and free, credit extension began worrying regulators in  the early 1980s, causing the central bank to commission two studies on how   to discourage financial institutions from overdrawing their accounts. Those   studies said a modest overdraft fee would encourage bankers to overdraft   less.       
The Fed also issued a policy requiring institutions that overdrew their  accounts to conduct self-evaluations, which were intended to create   daylight overdraft limits.   
  
Then, in September 1992, the governors approved the three-stage fee  systems.
