Deuda pública
At the beginning of 1998 value-added tax was introduced. The central government budget was in surplus in that year, most of which was used to repay foreign debt. Government debt to GDP had fallen from 27.30% to 26.20% at the end of 1998. However, the consumer boom was disrupted in mid 1998, as a result of the bank crisis when 14 banks went bankrupt. Unemployment increased and GDP growth slowed down to 1.9%. The recession that began at the end of 1998 continued through most of 1999, and after a period of expansion GDP in 1999 had a negative growth of −0.9%. In 1999 the government tightened its fiscal policy and revised the budget with a 7% cut in spending.
