BRASILIA, SEPT. 2 -- Brazil's finance minister, Luis Carlos Bresser Pereira, will meet Treasury Secretary James A. Baker III in Washington Tuesday to spell out his nation's negotiating position with commercial bankers next month.

Bresser Pereira's visit to Washington is part of his government's effort to make substantive progress with both official and bank creditors before the annual meeting of the International Monetary Fund on Sept 26.

He and his advisers will visit Europe, Japan and the United States, hoping to persuade creditors to agree to unconventional proposals that Bresser Pereira described as a "heroic solution" to the problem of Brazil's $108 billion debt.

"The financial community and authorities in creditor countries need fresh ideas," he said in an interview. "They must accept the notion that the muddling-through approach to the debt has failed and that after five years of this there are eight Latin American countries unable to pay interest."

He said the talks with Baker were "aimed at widening our relationship with the international financial system" and that he had been invited to Washington to provide details of the negotiating position Brazil will take in a meeting with its commercial creditors Sept. 23 in New York.

"We're going to make a professional proposal to the banks before the IMF meeting. They have no reason to be worried as things will really start happening soon," Bresser Pereira said.

{A Treasury Department spokesman confirmed that the meeting with Baker would take place, calling it "part of the ongoing discussions with Brazilian officials on their evolving domestic, economic and financial situation." He said the timing of the meeting "coincides with Mr. Bresser Pereira's return to Brazil from a European trip."}

In February, Brazil suspended interest payments on the $70 billion it owes commercial banks pending a new debt agreement.

Bresser Pereira confirmed that Brazil would ask the banks for $7.2 billion to make the interest payments through 1988. The banks will be asked to provide the money at a favorable interest rate, without the markup customarily applied by the banks to compensate for the risk.

Bresser Pereira also said Brazil will insist that its accord with the banks not require IMF monitoring of its economic performance. "We cannot accept that the banks suspend loans just because of a decision by the IMF," he said.

His chief economic adviser, Yoshiaki Nakano, who is attempting to persuade Japanese creditors to drop their insistence on an IMF agreement, said the four-year economic plan presented to bankers earlier this summer was the antithesis of fund orthodoxy.

"In traditional IMF programs domestic growth is considered a bonus only available to the debtor once it has generated a trade surplus to restart interest payments," Nakano said. "We have inverted all this by deciding we need 6 to 7 percent growth and then seeing how much will be left over to pay the creditors." That is how Brazil calculated its need for $7.2 billion.

Bresser Pereira also will repeat his attempt, first made in July, to persuade U.S. officials of the merits of his "heroic solution," which involves writing down the debt.

"There is a discount in the value of the debt in secondary markets, in the value of stocks of U.S. banks, and the reserves made by banks also imply a discount. So everyone knows half the debt is uncollectable," he said.

"If the debt is only worth 55 percent of its face value, why should we pay all of it?" he continued. "We need to consolidate all the old debt" and pay off banks with bonds after discounting the loans.

Bresser Pereira suggested that Brazil and the banks could split the discount between the face and market values of the loans. "Why shouldn't we keep 30 percent of the resulting discount for ourselves and hand 15 percent to the banks?" he said.
