The Collor Plan (), is the name given to a collection of economic reforms and inflation-stabilization plans carried out in Brazil during the presidency of Fernando Collor de Mello, between 1990 and 1992. The plan was officially called New Brazil Plan (Portuguese: Plano Brasil Novo), but it became closely associated with Collor himself, and "Plano Collor" became its de facto name.

The Collor plan combined fiscal and trade liberalization with radical inflation stabilization measures. The main inflation stabilization was coupled with an industrial and foreign trade reform program, the Industrial and Foreign Trade Policy (Portuguese: Política Industrial e de Comércio Exterior), better known as PICE, and a privatization program dubbed the "National Privatization Program" (Portuguese: Programa Nacional de Desestatização), better known as the PND.

The plan's economic theory had previously been laid out by economists Zelia Cardoso de Mello, Antônio Kandir, Álvaro Zini and Fábio Giambiagi.

The plan was announced on March 16, 1990, one day after Collor's inauguration.

  • Replacement of the existing currency, the Cruzado Novo by the Cruzeiro at a parity exchange rate (Cr$1.00 = NCz$1.00),
  • Freezing of 80% of private assets for 18 months (receiving the prevailing rate of inflation plus 6% in interest while frozen),
  • An extremely high tax on all financial transactions,
  • Indexation of taxes,
  • Elimination of most fiscal incentives,
  • Increase in the prices charged by public utilities,
  • The adoption of a floating exchange rate,
  • Gradual economic opening to foreign competition,
  • Temporary freeze on wages and prices,
  • The extinction of several government agencies, with plans for a reduction of over 300,000 government employees,
  • Stimulus of privatization and the beginning of economic deregulation.

Inflation stabilization plans

Three separate plans to stabilize inflation were carried out during Collor's two years in power. The first two, Collor Plans I and II, were headed by the finance minister, Zélia Cardoso de Mello. In May 1991, Zélia was replaced by Marcílio Marques Moreira, who carried out a homonymous plan, the Marcílio Plan (Portuguese: Plano Marcílio).

Collor Plan I

Brazil had suffered through several years of hyperinflation: in 1989, the year before Collor took office, average monthly inflation was 28.94%. The Collor Plan sought to stabilize inflation by "freezing" government liability (such as internal debt) To do so, it could utilize a wide combination of economic tools to affect the speed of re-monetization, such as taxes, exchange rates, money flow, credit and interest rates. The government had opened several "loopholes" which contributed to the increase of the money flow: Taxes and other government bills issued prior to the freeze could be paid with the old Cruzado, creating a form of "liquidity loophole" which was fully exploited by the private sector.

Collor Plan II

The second Collor Plan took place in January 1991.

Marcílio's plan was considered more gradual than its predecessors, utilizing a combination of high interest rates and a restrictive fiscal policy. President Fernando Collor de Mello had been impeached by congress four days earlier, on September 28, 1992, over charges of corruption in an influence-peddling scheme, marking the end of his government's attempts at ending hyperinflation.

Between the end of the Marcílio Plan and the beginning of the next "named" plan, the Plano Real, inflation continued to grow, reaching 48% in June 1994.

Altogether, some 18 companies worth US$4 billion were privatized between 1990 and 1992, mostly in the steel, fertilizer and petrochemical sectors.
