Russia’s losses from Ukrainian strikes on oil refineries have already reached 1% of GDP — and that's if Vladimir Putin is to be believed. Putin, of course, is hard to believe, but even 1% of GDP is an enormous sum — roughly half of the federal government's current budget deficit. And on top of that, mounting strikes mean the figure is likely only to rise — especially if the three recent attacks on Yandex data centers signal a new trend. According to The Insider’s estimates, each successful strike on an oil refinery costs Russia an average of around 23 billion rubles ($274 million), while a strike on an online marketplace warehouse costs 450,000 rubles ($5,350) per square meter. In the long run, these losses will weigh on the budget and drive down consumer demand — two key drivers of the Russian economy.
