Russia Plans 40% War Spending Surge Despite Internal Warnings of Unsustainable Costs

Russia is planning a dramatic escalation in war spending that contradicts earlier expectations of fiscal restraint, according to a series of Bloomberg reports in June 2026. The planned increase comes at a time when senior financial officials have privately warned President Vladimir Putin that the current level of defense expenditure is economically unsustainable.

The planned spending surge: 40% above budget

Russia intends to add 4–5 trillion rubles in war spending in 2026, roughly 40% above what the budget originally allocated . To cover the gap, authorities plan to borrow 2–3 trillion rubles on the domestic market . This additional spending would push total military expenditure to nearly 18 trillion rubles, according to estimates .

The fiscal crisis already underway

The planned increase arrives against a backdrop of severe fiscal strain:

• The federal budget deficit reached 6.01 trillion rubles in January–May 2026, or 2.6% of GDP —already 1.6 times the full-year target of 3.8 trillion rubles .
• The deficit was roughly double the level recorded during the same period in 2025 .
• Federal spending rose 17% year-on-year to 20.79 trillion rubles, while revenues grew only 0.3% .
• In March alone, spending surged 44% year-on-year, and the monthly deficit reached 1.1 trillion rubles .
• By April, Russia's budget deficit had already blown past its full-year target in just three months, reaching 4.6 trillion rubles versus a planned 3.8 trillion for the entire year .

Military spending: Q1 at record levels

• First-quarter 2026 military spending reached 5.9 trillion rubles, a 30% increase from 4.5 trillion rubles in Q1 2025 .
• Military spending accounted for 46% of all federal budget expenditures—nearly every second ruble spent by the Kremlin .
• That equates to roughly 65 billion rubles per day (nearly $916 million) and 2.7 billion rubles per hour .

Internal warnings to Putin

On June 1, 2026, Bloomberg reported that senior Finance Ministry and Central Bank officials had warned President Putin that spending on the war in Ukraine was on an unaffordable path . Bloomberg described it as the most serious sign of internal division in Moscow since the full-scale invasion began .

According to sources, financial officials urged cuts to defense spending, but Putin instead instructed them to find savings elsewhere in the budget without touching military outlays . In fact, the Defense Ministry was simultaneously requesting an additional 3 trillion rubles in funding .

The long-term debt burden

Servicing Russia's existing domestic debt already costs 4 trillion rubles in the current budget—about 9% of total federal spending, making it the fifth-largest line item . According to Bloomberg's calculations, over the next ten years Russia will spend at least 15% of its GDP solely on interest payments on public debt .

Implications for NATO and Ukraine's partners

The scale of planned Russian war spending suggests Moscow is preparing to sustain high levels of military expenditure despite earlier expectations that tighter budgets could slow the Kremlin's war machine . For Ukraine's partners, this points to a prolonged fiscal and military challenge rather than a near-term easing of Russian pressure .

A pattern of borrowing and strain

The available reporting supports a clear picture: Russia's budget was already under severe pressure before this additional spending was reported. The new plan to inject 4–5 trillion rubles more into war spending, financed through 2–3 trillion rubles in domestic borrowing, signals that the Kremlin is willing to accept widening deficits and mounting debt to continue the war effort, even as its own senior economic officials describe the path as unsustainable.
