Brazil had the largest foreign debt in the developing world, which made it particularly vulnerable to external shocks such as the oil shock of 1979. The high level of debt meant that Brazil had to pay large amounts of foreign currency to service its debt, which put pressure on its balance of payments and made it difficult to finance imported oil.
