Serhiy Hennadiyovych Arbuzov (Ukrainian: Сергій Геннадійович Арбузов, Russian: Сергей Геннадьевич Арбузов, romanized: Sergey Gennadyevich Arbuzov; born 24 March 1976) is a Ukrainian former banker and politician who briefly served as acting prime minister of Ukraine from 28 January to 22 February 2014, following the resignation of Mykola Azarov amidst the escalating Euromaidan movement.

After the Revolution of Dignity, Arbuzov fled to Russia, where he resides in the prestigious Rublevka area in Moscow in exile[3] and is wanted by the General Prosecutor of Ukraine.

[citation needed] As the chairman of the National Bank, he was best remembered for a set of measures directed at maintaining the stability of the hryvnia.

Arbuzov initiated the preparation of the so-called "road map" document, in which the Association Agreement process was set out on a phased basis.

[10]While in Government, Arbuzov also initiated a series of reforms in the taxation system, streamlining customs procedures, property rights protection, deregulation of business operations, value enhancement, etc.

[11] After weeks of Euromaidan protests and clashes, during which civilians were killed[13], Prime Minister Mykola Azarov offered his letter of resignation on 28 January 2014.

[16] Despite trying to bring about a resolution to the dispute between authorities and opposition, Sergij Arbuzov was bound to leave the country after the change of regime.

But according to Igor Fomin, Arbuzov's attorney for the defense, the proceedings should be ceased because "the channel has not made a profit for the whole period of its existence".

Latvian grand jury of officers of justice also denied that there are any cases in proceedings records in which Arbuzov could be a creditor or debtor.

[citation needed] In January 2015, Arbuzov and an experts group from the Association "Centre for Research into Economic and Sociocultural Upward Enhancement of CIS Countries, Central and Eastern Europe" addressed political and public figures of the West and Russia with the initiative to create the so-called "Coalition of intellect".

It was noted in an open letter that the conflict in Ukraine had threatened all the positive things that have been achieved in the development of the European security system over the past 25 years.
