Russia's war budget
meets a 14%
interest rate.

Short answer. Russia plans to spend 17.1 trillion roubles on defence in 2027, the highest figure since the invasion of Ukraine in 2022, and the central bank held its rate at 14% on 23 October because inflation is running above its path. The two facts are linked: the central bank has said that if fiscal parameters change, monetary policy may need to change with them. On the Relative Decline Index, Russia's fiscal engine already scores 26 out of 100 and its decline velocity is −5.6; this week's data are consistent with that scoring, and no score has been changed.

What moved this week: a hold that carries a fiscal message

On Friday 23 October the Bank of Russia kept its key rate at 14%, as markets expected. The decision ended a run of ten consecutive cuts between June 2025 and July 2026, and followed a hold on 11 September. What changed was the forecast. The bank now expects 2026 inflation of 7.1–7.6%, against 6–7% in September. Annual inflation was 6.8% as of 19 October; seasonally adjusted price growth averaged 8% annualised in the third quarter against 4.8% in the second, and core inflation rose to 6.2% from 4.5% (TASS, 23 October 2026).

The bank also said that if fiscal policy parameters change, monetary policy may need adjusting. That sentence matters more than the hold. It is the central bank telling the finance ministry that the two are drawing on the same pool of room. Its baseline puts the average 2027 key rate at 12.5–13.5% and 2026 GDP growth at 0.5–1% (Moscow Times, 23 October 2026).

How much will Russia spend on defence in 2027?

Draft budget documents seen by Reuters on 28 September put 2027 defence spending at 17.1 trillion roubles, about $202.6 billion at 84.4 roubles to the dollar. That is roughly 27% above the 13.5 trillion first budgeted for the year, and the highest figure since the war in Ukraine began. The three-year defence total in the documents is 50 trillion roubles. The 2026 figure is planned at 12.1 trillion roubles, but the actual outturn is classified and some military spending may sit in other budget lines (Reuters, 28 September 2026).

For scale, 12.1 trillion roubles is about a quarter of the 48.6 trillion roubles of total 2026 spending (approx., calculated from the same documents). The step from 12.1 to 17.1 trillion is a rise of about 41% (approx.) across one budget year, though the 2026 figure is a plan, not an outturn, so the true increase is uncertain. We publish the range of reading, not one number.

What do the deficit and debt numbers say?

The 2026 spending plan rises 13.2% to 48.6 trillion roubles, or 20.9% of GDP. The deficit estimate rises to 3.2% of GDP from the 1.6% in the budget law. Net borrowing for 2026 rises 26% to 5 trillion roubles, and the government plans to draw 459 billion roubles from the National Wealth Fund. Total 2027 borrowing is projected to rise 43% to 7.7 trillion roubles (Reuters, 28 September 2026).

This was visible earlier. In July the government’s budget portal implied a 2026 deficit of 4.83 trillion roubles against 3.79 trillion in the budget law, an overrun of about 1.04 trillion roubles, with first-half 2026 spending already producing a 5.73 trillion rouble deficit, 2.5% of GDP and 1.7 times the same period a year earlier. The finance ministry had also pushed back the date for restoring a zero primary deficit under the fiscal rule to 2029 (Reuters, 16 July 2026). In plain English: the fiscal rule is being deferred, not met.

State debt is projected at 21.7% of GDP in 2027, from 19.9% in 2026, above the 20% level authorities regard as safe. Russia’s debt is low by the standard of other major economies, so this is not a solvency story. It is a signal about direction and about which levers are left. New tax rises are planned for 2027, including a windfall tax on metals and mining companies expected to raise about 200 billion roubles a year. Meanwhile the 2026 oil and gas revenue estimate was cut to 7.6 trillion roubles from 8.9 trillion (Reuters, 28 September 2026).

Why did the central bank hold at 14%?

Because the arithmetic of the budget is inflationary. A wider deficit financed partly by borrowing, with a bigger defence line, adds demand, and the central bank has said inflation is running above its path. Holding at 14% leans against that, but a 14% policy rate also raises the cost of the debt the Treasury is issuing, and the cost of capital for the civilian industry the index scores under the productive engine. The bank’s own October statement is explicit that a change in fiscal parameters may require a change in monetary policy (TASS, 23 October 2026).

A 2027 baseline average rate of 12.5–13.5% means the cheaper money that would ease the squeeze is pushed out. Growth of 0.5–1% in 2026 is the cost. It is not collapse, and the figures here do not support that word. They support a slower, more specific claim: a war economy buying more military output each year from a base that is growing by less than 1%.

Which engine of decline does this bear on?

The index scores five engines for every nation, each 0–100 where 100 is healthy. Russia’s scores are demographic 14, fiscal 26, productive 29, institutional 22 and cohesive 31 (method page). The theory page assigns the fiscal engine a half-life of 10–25 years: faster than demography, slower than cohesion. This week is a fiscal-engine data point. The demographic engine, covered two weeks ago in Velocity Report W41, supplies the manpower constraint. The fiscal engine decides what can be bought with the manpower that remains.

Decline velocity is half trailing change and half forward momentum built from commitments already locked in. Debt already issued, and a defence line now rising by roughly a quarter, are locked-in commitments of exactly that kind. They do not change the −5.6 on the strength of one week’s news, and we do not alter any score from a single week. The next scheduled review is 31 December 2026.

What does this change about conflict risk?

Less than headlines suggest, and in a specific direction. The window logic on the conflict page says decline raises conflict risk when a power believes its relative position will be worse later than now. A budget that commits 50 trillion roubles to defence over three years is a statement about intentions to sustain the war, not about intentions to widen it. At the same time, the squeeze narrows the time over which that sustained effort is affordable without new taxes, higher borrowing or slower civilian growth.

That is a condition we price, not an event we predict. It does not tell us what Moscow will do at the end of a war or a pause in it. For the same pattern in a different theatre, see the South China Sea Velocity Report, where the variable was vessel counts rather than roubles.

What to watch next

Three dated markers follow. The Duma’s passage of the 2027–2029 budget will show whether the 17.1 trillion rouble defence line survives intact or is revised. The Bank of Russia’s next meeting is on 18 December 2026. The index’s own review is on 31 December 2026. If fiscal parameters change, the bank has said monetary policy may need adjusting; if oil and gas revenue falls below the 7.6 trillion rouble estimate, the gap widens without any change in spending.
