Governments must spend immense resources to sustain large-scale war, and Russia is no exception. Since its 2022 invasion of Ukraine, Russia has poured vast reserves of funding, equipment and manpower alike into its war effort, and its economy bears the wounds to prove it, made worse by mounting Western sanctions . However, a largely qualitative analysis of Russia's economy suggests that Moscow could continue its war with Ukraine at current levels of intensity for at least another two to three years under current economic constraints. This extended timeline may reduce the Russian government's incentive to negotiate a political settlement as long as Western support for Ukraine does not force Moscow to dig significantly deeper into its dwindling resources. However, continued war would come with significant short- and long-term economic costs for Russia, despite the temporary boost in economic growth following Moscow's sharp increase in defense expenditure.
