A stark warning from Russia’s top financial officials to President Vladimir Putin has laid bare a bitter internal struggle over the sustainability of the country’s war-driven economic model. According to a Bloomberg investigation based on multiple insider sources, the finance ministry and the central bank have told the Kremlin that the ballooning defence budget risks pushing the public finances into a perilous deficit. The agencies involved characterised this as the most severe discord within Moscow’s ruling elite since the full-scale invasion of Ukraine began. The episode reveals a fundamental tension: how long can the Russian state afford to wage a war that is consuming an ever-larger share of national wealth?

The economic bloc, led by the finance ministry, has argued that without curbing military expenditure, the fiscal situation will become untenable. They proposed actual reductions in defence allocations. But this push has been met with fierce resistance from the defence ministry and key Kremlin hawks, who not only reject cuts but are demanding additional funds—close to three trillion roubles, or roughly $36 billion, to cover a projected shortfall in 2026. Confronted with the impasse, Putin opted to protect the war effort, instructing his ministers to find savings in other, more socially oriented budget lines. The instruction, confirmed by several sources, underscores the president’s determination to prioritise the military campaign even as the economic ground shifts beneath him.

The scale of the imbalance is staggering. In just the first four months of this year, the budget deficit reached 5.9 trillion roubles (around €70.5 billion), according to data cited by Bild, pushing the shortfall to a record level. Overall defence spending has surged to almost 40% of total federal expenditure, creating what analysts describe as a classic “guns or butter” dilemma. With sanctions limiting access to global capital markets and energy revenues under pressure, Moscow’s fiscal buffers are eroding. The central bank, which has kept interest rates painfully high to tame inflation stoked by wartime demand, has privately expressed alarm that further deficit expansion could destabilise the entire financial system.

Viewed from Washington and European capitals, the internal Kremlin discord is a telling indicator that Western economic coercion is beginning to bite. Diplomats point to the paradox: Putin can keep ordering savings elsewhere, but eventually the scope for such manoeuvres shrinks. In Tehran, where state media republished the Bloomberg report with evident interest, the story resonates with Iran’s own experience of trying to fund military adventures under external sanctions. Analysts in London note that the rift is a gamble; should public services degrade noticeably, the compact between the regime and the population could fray. For now, the Kremlin appears willing to run that risk, betting that economic pain can be contained long enough for battlefield outcomes to justify the cost.

The struggle is unlikely to be resolved soon. As the war drags into its third year with no end in sight, the fiscal mathematics will only harden. Putin’s decision to shield the defence budget may temporarily paper over the splits, but it does nothing to address the structural imbalances. The debate inside Moscow mirrors an older Soviet dilemma—whether the state can indefinitely subordinate civilian welfare to military might without fracturing. The coming months will test whether Russia’s economic chiefs can engineer a soft landing, or whether the contradictions of a war economy finally force a reckoning.
