[6] Berat Albayrak entered the Turkish Grand National Assembly as a member of parliament for the Justice and Development Party (AKP) in the June 7, 2015 elections.

On September 12, 2015, during the 5th Ordinary Congress of the AKP, he was appointed to the party's Central Executive and Decision Board (MKYK).

On September 12, 2018, he was also appointed as the deputy chairman of the Turkey Wealth Fund,[8] and on October 2, 2018, he became a member of the Defense Industry Executive Committee by presidential decree.

[9][10][11] Additionally, on July 15, 2018, Albayrak was selected as a member of the Supreme Military Council (YAŞ) by presidential decree.

For the first time in Turkey, airborne gravity-magnetic data collection was implemented over a wide region, including Şemdinli, Cizre, Van, and Siirt.

Additionally, the country's first deep drilling project was carried out in Çukurca, Hakkâri, reaching a depth of 4,500 meters.

Turkey's first drilling ship, Fatih, made a historic discovery of 710 billion cubic meters of natural gas in the Black Sea.

Berat Albayrak implemented a series of monetary and fiscal reforms to combat inflation, reducing it from around 25% to single digits within a year.

[18] In 2020, through public banks, Turkey offered the longest-term and lowest-rate housing loans in its history (0.49%), allowing hundreds of thousands of lower and middle-income individuals to become homeowners.

[24] During his tenure, Albayrak also met with U.S. president Donald Trump at the Oval Office, where they discussed a range of issues, including the S-400 missile system, regional affairs, and bilateral trade relations.

Observers noted that his appointment raised concerns within financial circles, with fears about the concentration of too much power in the hands of a single politician.

[26][27] Albayrak's presentations to international investors and sector representatives as the minister of treasury were also criticized in the media for being unconvincing.

These critiques highlighted a perceived lack of confidence in his ability to effectively communicate Turkey's economic policies and attract foreign investment.

The article, titled "The Son-in-Law Knows the Business," noted that the land, currently classified as agricultural, falls within the "residential area" boundaries established by the Ministry of Environment and Urbanization's master plan for Kanal İstanbul.

[29] In response to the allegations made by the news reports and online platforms, Berat Albayrak initiated legal proceedings.

The Istanbul Anatolian 7th Criminal Court ruled in favor of Albayrak, deciding to impose a ban on access to the relevant articles and websites.

Additionally, an investigation was launched against Cumhuriyet reporter Hazal Ocak on charges of "insulting a public official.

This statement was interpreted by Fenerbahçe supporters as a reference to the 2011 Turkish football match-fixing scandal and implied that Trabzonspor was the rightful champion of that season.
