International Monetary Fund (IMF) chief Christine Lagarde said the rescue deal agreed for Cyprus is "sustainable" and financially sound.
Although the plan allows the IMF to make a contribution to the loan, Ms Lagarde said it was too early to say how much the lender would provide towards the package.
"We believe the proposal is sustainable for the Cyprus economy ... The IMF is considering proposing a contribution to the financing of this package", she told a news conference.
"The exact amount is not yet specified. It will take some time," Ms Lagarde added.
Cyprus' rescue deal has sent shivers through southern Europe after a key eurozone figure said it would be a model for future bailouts.
The future is uncertain for the people who must live with the consequences of Cyprus' "painful" bailout deal.
The Dutch Finance Minister has said the bank levy 'bail-in' on large depositors "pushes back the risks" from the rest of the eurozone.
