In 1996, Srimani was removed from the Cabinet by President Chandrika Kumaratunga, and simultaneously Srimani and her party had a dispute over the affiliation to the Government. Karunanayake was more disposed toward the UNP, and as a result Srimani fired him from the DUNF-Lalith Front.

Following the election of Maithripala Sirisena as President in 2015, he was appointed as the Minister of Finance. He presented the controversial interim budget soon thereafter. In 2017, The Banker magazine selected Karunanayake as the best finance minister in Asia pacific for securing a $1.5 billion International Monetary Fund loan programme to avoid a balance of payments crisis, replenish reserves and rebuild confidence among international investors.

Karunanayake was summoned to testify before the Commission, and stated that he had no knowledge of how his rent was paid. This caused a major public outcry, with calls for his resignation and negative feedback to many of the proposals he presented to President Sirisena, such as his request for the use of Visumpaya as his official residence as Minister of Foreign Affairs. Many within the government, both SLFP and UNP members as well as the President, wanted Karunanayake to resign. He resigned from the post of Minister of Foreign Affrairs on 10 August 2017. In October 2017, Anika Wijesuriya, who testified against Ravi Karunanayake, had left Sri Lanka following threats to her life.
