Affected by the fall in Russian crude oil prices, Russia's oil revenue in November decreased year-on-year for the second consecutive month. According to data released by the Russian Ministry of Finance on Wednesday, oil-related taxes are the main source of funding for the Russia-Ukraine conflict, creating 605.2 billion rubles ($5.8 billion) in revenue for the Russian budget last month, a decrease of about 21% from the same period last year. Despite the tense geopolitical situation in the Middle East, OPEC+ decided in November to continue the production cut, but due to concerns about global oversupply, crude oil prices plummeted. The decline in oil revenue may partly limit the Kremlin's ability to fund the Russia-Ukraine war. Russia plans to continue increasing defense and domestic security expenditures in 2025, with a total cost exceeding 13 trillion rubles, reaching a historical high.
