On the eve of his inauguration, Fernando Collor asked the Sarney government to declare a bank holiday, which only increased speculation about the measures that would be announced.

[12] During his administration, the country opened up to the external market, and efforts were made to eliminate or reduce anti-import barriers, adopting economic liberalization measures in favour of Brazil's insertion in the globalization scenario.

[17] One of the important points of the plan included the confiscation of bank deposits exceeding Cr$50,000.00 (fifty thousand cruzeiros) for a period of eighteen months, aiming to reduce the amount of money in circulation, as well as changes in the calculation of monetary correction and in the operation of financial investments.

Even though bank confiscation was a flagrant disrespect to the constitutional right to property, the economic plan led by Minister of Economy Zélia Cardoso de Mello was approved by the National Congress in a matter of days.

[18][19] According to an article[20] by the academic Carlos Eduardo Carvalho, Professor of the Department of Economics at the Pontifical Catholic University of São Paulo and coordinator of the Government Program of the PT's candidacy for president in 1989, the policy measure executed by the Collor government, which became known as confiscation, was not originally part of the Collor Plan and was conceived almost on the eve of its implementation.

Despite the differences in general economic strategies, the candidacies that faced each other amidst the sharp acceleration of price hikes, exposed to the risks of open hyperinflation in the second half of 1989, had no stabilization policies of their own.

In the legislative branch, the PMDB maintained the largest number of seats in both the Chamber of Deputies and the Federal Senate, and as a result, kept the command of congress for the next two years, a situation that had been in place since the return of the civilians to power in 1985.

However, the most significant change would come in May 1991, when Ambassador Marcílio Marques Moreira took over the Ministry of Economy,[24] confirming Collor's appreciation for individuals with a technical and academic profile to the detriment of "career politicians", a trend that would only be reversed in 1992 when he carried out two reforms in his team: one in April and another on the eve of his removal when he made room for conservative political officials.

[25] Over time, the failure of his economic policy and the frequent accusations involving his direct aides (including first lady Rosane Malta, president of the Brazilian Legion of Assistance) resulted in a progressive wearing down of his government.

According to Liz Batista, for Estadão (2021): "The campaigns that immunized against polio, measles, pertussis, diphtheria and tetanus, counted on the active participation of Collor.

[39] Due to the event, he transferred the federal capital to Rio de Janeiro from 3–14 July 1992, and called on the Armed Forces to provide security.

[40] According to Celso Lafer (2012), who was his foreign minister: "President Collor's political will in this field is also very representative of his commitment to reformulate Brazil's domestic and international agenda in the post-Cold War world, which is an identifying mark of his government".

[44] On 29 September, by 441 to 38 votes, the Chamber of Deputies authorizes the opening of impeachment proceedings against the president, which implies his temporary removal from office until a final decision is made by the Federal Senate.
