Federal regulators said Thursday that all but 27 banks  and thrifts with $4.8 billion of assets are completely ready for the   year-2000 date change.   
However, the agencies said at least some of the laggards face  relatively minor problems such as not documenting their contingency plans.   "It's not necessarily because there are problems with their systems," a   spokesman for the Federal Deposit Insurance Corp. said.     
  
Some of the institutions deemed unprepared have been named publicly,  and there is a concern that the enforcement actions could lead customers to   yank deposits. But the FDIC spokesman seemed unfazed, saying, "Many   institutions can withstand a run."     
Spurred by opinion polls indicating fear among some consumers, Federal  Reserve Governor Edward W. Kelley Jr. was joined by the heads of the FDIC,   the National Credit Union Administration, the Office of the Comptroller of   the Currency, and the Office of Thrift Supervision to urge the public to   keep cool heads and leave their money in the bank.       
  
Just in case people want to get cash, the Fed has more than $200  billion stored in vaults, Mr. Kelley said. The regulators will conduct   status checks on bank operations, liquidity, and customer behavior before   and after Dec. 31.     
The FDIC produced a video for banks to play in their lobbies featuring  regulators explaining how banks prepared for the year 2000 and telling   customers that the safest place for their money is the bank.
