The measures, which the HNB adopted without consultations with the government and the Finance Ministry, would probably lead to a decrease in the banks' liquid assets and an increase in interest rates, Suker said at a government session.
The central bank on Wednesday raised compulsory bank reserves for new foreign loans from 30 to 40 percent.
Suker dismissed reports that the state was generating the growth of the foreign debt.
The state could have sought the most favourable loans abroad, but except for the Euro bonds in the amount of 500 million euros issued in early 2004, it has not sought new loans on the foreign market, Suker said, adding that the government had sought loans on the domestic market.
Commenting on the opposition's claims that the public debt was growing, Suker said that the public debt was not dramatically high.
The budgetary deficit can be covered either with loans or privatisation revenue. In 2004 the state did not have any significant privatisation revenue and it had to seek loans to cover the deficit, the minister said.
The public debt is the result of the deficit, and the government's goal is to reduce the deficit to below three percent by 2007, he said.
Government members said the government had reduced the budgetary deficit from 6.3 percent of GDP in 2003 to 4.9 percent in 2004, which is still slightly more than the planned 4.5 percent of GDP.
Suker dismissed reports that incentives for citizens saving money to take housing loans would be cancelled, explaining that the government only intended to find a better model of encouraging saving for housing loans.
The government also decided to make public a memorandum signed by the successor states to the former Yugoslavia and the Russian Federation on clearing Russia's debt to the former Yugoslav federation.
Croatia expects a share of 185.7 million of the debt and negotiations have been held on paying the debt by giving Croatia equipment for thermal power plants in Sisak and Osijek, two fire-fighting planes, and by constructing a gas supply system on the Croatian-Hungarian border.
The memorandum, signed in September 2003, has to be confirmed to enable the start of talks on the payment of the debt.
Deputy Prime Minister Damir Polancec was chosen to head a commission to coordinate the financing of educational, cultural, scientific and health projects of the Croat community in Bosnia-Herzegovina, for which the Croatian government has provided 26.2 million kuna from this year's budget.
