Imagine: the failure of $500 billion in banking assets; the Bank  Insurance Fund in the red for seven years; banks paying 28-cent premiums   through 1997.   
That's the snapshot the Federal Deposit Insurance Corp. took of the  banking industry in mid-1992. 
  
What really happened?
Just 10% of the assets predicted to fail actually tanked. Three record-  setting years of bank earnings fueled recapitalization of the insurance   fund in May 1995 - 11 years ahead of schedule. More than 90% of all banks   pay no insurance premiums.     
  
As former FDIC chairman L. William Seidman liked to say: People who gaze  into crystal balls often end up chewing glass. 
Today, those shards are making it tough for FDIC prognosticators to  raise any red flags. But the agency's executives are paid to worry about   the long haul, and if they can't make the case for caution, they may simply   change the way premiums are levied.     
The groundwork was laid in November when the FDIC decided to charge  between zero and 27 cents for every $100 of domestic deposits, depending on   how much risk a bank poses the fund. The best banks simply pay the   statutory minimum of $2,000 a year for insurance; as of Jan. 1, that's more   than 9,700 banks, holding 95% of the industry's assets.       
  
It's hard to claim that rates are risk-based - as required by law - when  so many banks are not paying premiums. 
The agency's November analysis of the premium cut included two charts.  The first shows that 35% of the banks failing between 1980 and 1994 held   Camel 1 or 2 ratings two years before closing; 55% held one of the two   highest ratings three years before failing.     
The second chart notes that regulators judged 80% of the banks that  failed between 1987 and 1994 to be well capitalized just three years before   they closed.   
The FDIC was trying to illustrate a point: Good banks can die quickly.  Agency officials are concerned about classifying so many banks as the best   in the business.   
  
"All of the institutions in the A-1 category are not equal," Roger  Watson, the FDIC's research director, said in an interview last week. 
Mr. Watson acknowledged he has "been fooling around with various and  sundry analyses to see what makes more sense than what we have now. 
"Expanding the matrix eventually probably will make sense," he said. "It  will take some time to convince people." 
The matrix is a nine-box grid the FDIC uses to determine how much each  bank will be charged for insurance. One axis plots a bank's capital, the   other its supervisory rating. The 9,723 banks that qualified for zero   premiums are in the A-1 box at the top left of the grid. They are well   capitalized and have a high Camel rating.       
But Mr. Watson noted that these factors judge a bank's past - not its  future. 
"You can't look at any bank today and judge it solely by its Camel  rating and capital," he said. "There are many other factors. 
"The real trick is to look for leading indicators of problems."
The FDIC is leaning toward adding another dimension to the matrix -  possibly a bank's debt ratings or trends in its operating characteristics,   such as earnings or problem assets - rather than simply adding more boxes.   
"We're trying to come to grips with a comprehensive and reasonable  approach to measuring risks in banks," Mr. Watson said. "That makes more   sense than tinkering around the edges."s
