Sergeyev was appointed Minister of Defense in 1997 by Russian President Boris Yeltsin.
He was promoted to Marshal of Russia on 21 November 1997, the only Russian military officer to achieve that rank.
Sergeyev accepted reform within a limited budget under civilian political control.
The number of military educational establishments was reduced markedly from their previous levels, which had not changed since Soviet times.
A number of army divisions were given "permanent readiness" status, which was supposed to bring them up to 80 percent manning and 100 percent equipment holdings.
Sergeyev directed most of his efforts toward promoting the interests of the Strategic Rocket Forces.
All military space forces were absorbed into the Strategic Rocket Forces, and the Ground Forces Headquarters was abolished.
The Airborne Forces suffered some reductions, while the Naval Infantry only escaped due to their competent performance in Chechnya.
Much of the available procurement money was invested in acquiring new rockets.

In December 1999, Sergeyev called NATO enlargement, in and of itself, a threat to global and European collective security and world politics.
He particularly stressed the deployment and use of NATO forces out of area without a United Nations or OSCE mandate as a threat that devalues confidence-building measures, arms control treaties and security.

Sergeyev was dismissed as defense minister in March 2001 and was replaced by Sergei Ivanov.

Sergeyev died on 10 November 2006 from the effects of blood cancer.
