The impeachment process having lasted for nearly 9 months ended by Dilma Rousseff being out of office. Michel Temer officially became the president of Brazil，however，his ruling may not go as smoothly as expected. Party politics has entered another round of differentiation and re-organization in the coming presidential election in 2018. And the influence derived from continuous corruption probe may be immeasurable. The second consecutive year of deep recession remains to be the biggest challenge for the new government. Although President Temer has proposed some reform measures such as limiting fiscal expenditure，reducing public debt and privatizing state-owned enterprises，most of them must be approved by Congress in the form of law amendment，thus there exist a lot of uncertainties. In the short term，unemployment rate and poverty rate have increased. Due to the need of re-evaluating the protectionist policies pursued by Trump government of the United States，the adjustment of Brazil’s corresponding policies remains to be seen. In 2017，Brazil’s situation will be more complex than expected.
