Inside the Kremlin's Fiscal Crack-Up: Top Officials Warn Putin War Spending Is “Unsustainable”

That exchange, and the leaked documents that followed, reveal a Kremlin inner circle fracturing over economic strategy just as the official data confirms the first quarterly GDP contraction since early 2023.

The Private Warnings and Putin's Rejection

The warnings came from the highest reaches of Russia's economic bureaucracy—Finance Minister Anton Siluanov and representatives from the Central Bank . They told the Kremlin that the current structure of military spending carries the “risk of a rapidly growing budget deficit” and urged an immediate review and partial cuts to defense programs .

Bloomberg's report, citing people familiar with the discussions, specified that the officials believe the deficit is on an “unsustainable” trajectory without a course correction . Putin's response was unequivocal: no defense cuts. He told the Finance Ministry to find the money from other non-war budget lines .

The internal standoff spilled into public view when the Financial Times obtained a February letter from Siluanov to the cabinet. In it, Siluanov warned that war spending would exceed its budget by at least 2 trillion rubles (approximately $28 billion) in 2026, with a “negative scenario” pushing that overrun to 4 trillion rubles. He projected similar overspends of 4 trillion rubles in both 2027 and 2028, and urged the government to freeze roughly 2.9 trillion rubles ($40.8 billion) in planned non-war spending to compensate .

How Large Is the Defense Ministry's Budget Hole?

The budgetary cracks are no longer contained to classified briefings. Two people close to the government told Bloomberg that the Defense Ministry itself faces a shortfall of 1.3 trillion rubles (roughly $18 billion) in its 2026 budget . That gap sits within a broader fiscal deterioration: Russia had planned a full-year 2026 deficit of 3.8 trillion rubles, but the deficit had already ballooned to 5.9 trillion rubles in the first four months alone .

War expenditures now consume approximately 40% of the entire federal budget, a level that Siluanov and the Central Bank privately warn is incompatible with stable public finances .

Russia's Economy Contracts for the First Time in Three Years

The fiscal alarm bells coincide with a sharp deterioration in real economic activity. Russia's GDP contracted in Q1 2026 by 0.2% year-on-year, according to the official estimate published by the Federal State Statistics Service (Rosstat) on May 15, 2026 . The Bank of Russia reported a steeper estimate of 0.5% year-on-year, while the Russian Academy of Sciences' Institute of Economic Forecasting (INP) put the contraction at 1.5% .

This is Russia’s first quarterly GDP decline in three years, and it prompted the government to slash its full-year 2026 growth forecast to just 0.4%, down from an earlier estimate of 1.3% .

What Is Driving the Economic Downturn?

The contraction is not a single-shock event. Multiple overlapping pressures are grinding down Russia's wartime economy:

• Western sanctions continue to constrain energy export revenues, restrict technology imports, and dampen industrial output .
• Elevated interest rates, maintained by the Central Bank to fight inflation, have choked credit availability and private investment .
• A January 2026 VAT increase weighed on consumer demand and broader economic activity early in the year .
• Labor shortages from mobilization and emigration have hollowed out key sectors, including manufacturing and construction .
• Ukrainian drone strikes on oil refineries have damaged refining capacity, disrupted fuel supplies, and eaten into a crucial source of export revenue .
• Persistent inflation, running at approximately 5.2%, continues to erode real household purchasing power .
• Budget austerity outside defense—as the Finance Ministry moves to freeze nearly all non-war spending—is squeezing public investment and social services .

Looming Over SPIEF: A Fractured Inner Circle

Putin is scheduled to address the St. Petersburg International Economic Forum (SPIEF) in early June 2026, an annual gathering that for years served as a showcase of Russian economic stability and openness to foreign capital. This year it arrives as an uncomfortable backdrop.

The Bloomberg and Financial Times reports, published just days before the forum, show that the financial wing of Russia's government is openly signaling that the war's current price tag is unaffordable . The dissonance with Putin's public stance—demanding uninterrupted military spending while his own finance minister privately pushes for sweeping budget freezes—is stark.

With growth stalling, the deficit hitting record levels, and defense spending consuming nearly 40% of the budget, SPIEF 2026 is set to be less about attracting investment and more about whether Russia's financial establishment can manage the contradictions of a war economy it privately believes is unsustainable .
