"According to some estimates, Bosnia can get one billion euros from the IMF," the governor was quoted by the Dnevni Avaz daily as saying on Saturday.
Bosnia is registering deficits in budgets at all government levels, and the role of the IMF in such a situation is irreplaceable, he said.
Arrangements with the IMF do not only bring money but also pave the way for thorough reforms and better tax discipline which Bosnian state bodies need, Kozaric said.
"This can to some extent improve Bosnia's status on the international scene and can positively impact the country's credit rating," he said.
The governor admits that there is no doubt that IMF requirements for granting a loan can be "demanding and painful" but he holds that this will be the best way to prepare Bosnia to face the economic crisis.
A delegation of IMF is expected to arrive in Sarajevo on 13 April for talks with the Bosnian authorities.
In late March, Serbia and the IMF reached a deal on a EUR 3 billion loan for this and next year.
This loan programme, which replaced a EUR 520 million stand-by arrangement agreed in January, was hailed by Belgrade as a measure for bringing stability to the Serbian financial sector.
