The official reason for his resignation states that he resigned due to the need to get treatment for a serious illness, however there is some speculation that a dispute with Defense Minister Vazgen Sargsyan was the real reason for Sargsyan's resignation. After serving as Armenian Prime Minister between 1996 and 1997, he was appointed as Special Advisor to the President of the European Bank for Reconstruction and Development (EBRD) and as a Governor of EBRD from 1998 to 2000.

Election

President Serzh Sargsyan on 19 January 2018 recommended the candidacy of Sarkissian for President to be supported by the ruling Republican Party during the 2018 Armenian presidential election. He also enjoyed additional support from the Armenian Revolutionary Federation bloc as well as from the Tsarukian Parliamentary bloc.

He was elected president by a majority of the National Assembly on 2 March 2018 with 90 votes in a 105-member House. Sargsyan was the only candidate in the election.

Inauguration

Sargsyan was inaugurated on 9 April 2018. The inauguration ceremony took place at the Karen Demirchyan Complex in Yerevan. After the ceremony, he visited the Yerablur military pantheon, and laid a wreath at the monument with Defense Minister Vigen Sargsyan.

Presidency 

On inauguration day, the government led by Karen Karapetyan resigned and parties in the National Assembly had a week to put forward their proposals for prime minister. Former president Serzh Sargsyan was unanimously nominated by the members of ruling parties in the National Assembly on 16 April, and was confirmed as prime minister on 17 April. However, Sarkissian's election as prime minister was met by large-scale protests, and he resigned six days after taking the office. Karapetyan was subsequently appointed to serve as acting prime minister. On 8 May 2018, Nikol Pashinyan was elected prime minister by the National Assembly in a 59–42 vote.

Sargsyan visited Tbilisi on 26 May 2018 in his first official foreign visit to participate in the centennial celebrations of the founding of the Democratic Republic of Georgia. During his visit, he held talks with his Georgian counterpart Giorgi Margvelashvili as well as held meetings with Bidzina Ivanishvili and Sauli Niinistö.

In June 2018, Sargsyan proposed changes to the constitution to balance the President's power with the Prime Minister's power. On the eve of the centennial anniversary of the end to First World War, Sargsyan told the Schweizer Radio und Fernsehen in an interview said that he would say the following to Turkish President Recep Tayyip Erdoğan in regards to the Armenian Genocide:

"First, I would tell him good morning Mr. President, I think we have an issue to discuss together. You are the President of Turkey and I am the President of Armenia. My family, my grandparents are from Erzrum, Van and Bitlis and there is a history behind my own family. Why not start talking about the relations between Turkey and Armenia? Why not speak about our individual stories?"

While visiting the Kazakhstani city of Almaty in May 2019, he said that his country could become an "international financial center" and can become a "cooperation bridge between Eurasia and EU". He said his remarks at the 15th annual Eurasian Media Forum, of which he is a co-founder.

Role after the Karabakh conflict

In the early stages of the 2020 Nagorno-Karabakh conflict, Sarkissian gave numerous interviews to international news organizations during which he appealed for action against the Government of Turkey and the actions of the Azerbaijani Armed Forces, telling CNBC’s Hadley Gamble to “Imagine Caucasus becoming another Syria?” In another interview to the German Bild tabloid, he compared the situation in Stepanakert to German towns during World War II. After the ceasefire agreement was signed in early November, Sarkissian held a meeting with Karekin II, where they both made a call to declare 22 November as the Day of Remembrance of the Heroes who fell for the Defense of the Motherland in the Artsakh Liberation War. On 16 November, in an address to the nation, he concluded that snap parliamentary elections and Pashinyan's resignation were inevitable in light of the protests, proposing that a process be overseen and managed by an interim "National Accord Government". In early 2021, he called for the creation of a "Fourth Republic".
