On Sunday, Belgium, Luxembourg, and the Netherlands injected more than $16 billion into banking and insurance giant Fortis, whose profits have tumbled in the past year.
Iceland's government says it is buying a 75 percent stake in the country's third-largest bank, Glitnir.
Authorities in Reykjavik say the move is aimed at ensuring market stability by easing the bank's liquidity problems.
The global banking crisis has largely been linked to lenders making bad home loans and then getting stuck with bad mortgages, shrinking available credit for customers and businesses.
