With new IMF loan in hand, Brazilians come calling on private banks for $4.4 billion

Now that the Brazilians have bossa-novaed their way past the International Monetary Fund (IMF) and the Bank for International Settlements, they are hoping the private banks will likewise dance with them.

In a meeting Monday afternoon attended by people from 110 banks representing 90 percent of the country's external debt, the Central Bank of Brazil asked for an additional $4.4 billion in loans for next year. According to Central Bank figures, this would swell the country's debt to $87.9 billion next year, an increase of 8 percent.

The Brazilians told the bankers they intended to ''adjust to the world situation,'' and thus planned to make changes in their economy. This economic plan has already been approved by the IMF.

''The IMF has discussed the economic program and found it viable and consistent,'' Carlos Langoni, head of the Central Bank, said after the meeting with the bankers. Among the changes, he said, will be an acceleration in the rate at which Brazil devalues the cruzeiro to keep ahead of inflation; reduction in the public-sector deficit to 3.5 percent of gross domestic product; and readjustment of interest rates by elimating agricultural subsidies.
