Allied Irish Bank has seen its share price fall by another 25% today after yesterday's turmoil on the Irish Stock Exchange.
AIB shares were worth just 22c at lunchtime, while Irish Life and Permanent shares were also down 9% to €1.
Bank of Ireland, meanwhile, has seen its share price fall very slightly to 34c after rising to 43c in early trading.
The turbulence is being attributed to an ongoing lack of confidence in the Irish banking system following the Government's decision to nationalise Anglo Irish Bank.
