BRAZIL: $100 Billion

Brazil, the developing world's biggest debtor, moved from severe recession to economic growth in 1984, but its inflation continues to exceed 200 percent a year. It does not need to borrow new bank money this year and is current on all its interest payments -- mainly because a huge $13 billion trade surplus has generated the foreign exchange it needs. Exports are the source of most of its economic growth. Brazil is in the final year of a three-year $4.5 billion International Monetary Fund program. It is in the middle of talks with its bank lenders, hoping to convince them to stretch out repayment bank debt for a decade or more. Last week Tancredo Neves was elected Brazil's first civilian president in 20 years. He will have to cope with an austere future, and it is unclear whether he will play a role in current bank talks or leave it totally to the current military government -- which is scheduled to go out of office in March. MEXICO: $96 Billion

TThe country that triggered the so-called Latin American debt crisis is now considered best at improving its condition by adopting orthodox measures to cut spending and reduce reliance upon foreign debt. Like Brazil, Mexico has taken austerity measures -- in conjunction with a three-year, $3.7 billion 1983 IMF program -- that triggered a sharp recession. But Mexico began to generate the dollars it needed to pay its debts and now appears to be emerging from the recession. Last August Mexico reached a tentative pact with banks to stretch out repayment of its $50 billion in outstanding bank debts over 14 years. This was considered the first part of Phase II of the debt problem, and still must be approved by the country's 800 bank lenders. Inflation remains a problem. ARGENTINA: $47 Billion

Last month, after nearly two years of foot-dragging, Argentina agreed to a one-year, $1.4 billion IMF program, and banks agreed to lend the country $4.2 billion in 1985 and stretch out repayment of another $13.4 billion in debts that already have come due or will before the end of the year. The country still is in arrears by $500 million on interest payments due to banks, even though it paid $850 million on Dec. 31. While other major debtor countries are negotiating long-term pact with lenders, Argentina has an agreement for a year only, as were the initial bank accords with Mexico and Brazil. VENEZUELA: $35 Billion

Venezuela has been hurt by lower oil prices, but it is wealthy enough to not need new bank loans to keep going in 1983 and 1984. It paid interest, but no principal for two years. The country finally reached a tentative long-term repayment plan in September covering $20.75 billion of bank debts. But the agreement is not expected to be signed until next spring. Unlike other debtors, Venezuela did not need IMF assistance and, as a result, took no economic steps that needed IMF approval. But the austerity steps the country took were similar to Mexico's and Brazil's. CHILE: 20 Billion

The country took nearly all the austerity steps recommended by the International Monetary Fund, but remains in serious economic straits because nearly all its exports are commodities -- led by copper -- which have been seriously depressed. Its two-year, $530 million IMF program expired last week, and it is negotiating with the international agency. Chile fell out of compliance several times. While other debtor countries have a large level of foreign-aid-related debt on which rates are low, nearly all of Chile's loans are commercial-rate bank loans. Chile's ruling military dictatorship faces strong internal opposition as well. PERU: $14 Billion

Peru has fallen out of compliance with its three-year IMF program and is far in arrears on payments due its banks. The country is making enough interest payments to keep the debts from falling six months in arrears and being declared problem loans by U.S. regulators and banks. No new IMF program -- and the international and commercial bank money that accompanies such a program -- is expected before a new government takes over in June. Like Chile, Peru has been decimated by low price and demand for commodity exports. Unlike Chile, it has a fair amount of official loans at concessionary interest rates. PHILIPPINES: $24 Billion

After a year of wrangling, the Philippines came to terms with bank lenders in November. Banks agreed to lend the country $925 million in new money and to stretch out repayment of $5.8 billion of debts that mature between Oct. 17, 1983, and Dec. 31, 1986. The country also reached an accord with the IMF under which that agency will pump in $630 million. The Philippines also faces internal political difficulies and opposition to strongman President Ferdinand Marcos. POLAND: $27 Billion

Severe internal political problems make Poland among the worst-off of the debtor countries. It has restructured its bank debt through 1987 -- most of Poland's bank loans are from European countries. Last week it was reported that 17 western governments have reached an agreement in principle to stretch out repayment of principal and interest on loans from other governments. The pact covers the period from Jan. 1, 1982, to Dec. 31, 1984, and totals about $3 billion. YUGOSLAVIA: $19 Billion

Last week "substantial progress" was reported in negotiating a repayment schedule on the $3.5 billion of commercial bank debt that comes due between 1985 and 1988. The country was tarnished by Poland's problems, which caused banks to back away from nearly all Eastern European lending. It rescheduled $1.2 billion in maturing bank loans in 1983 and $1.2 billion last year. The country did not need new loans last year. It is in compliance with an IMF program.
