Russia’s 2027 budget: debt, banks and civilian credit

Russia’s war budget also lands on a banker’s desk. Government borrowing needs a buyer, and that buyer expects a return. As financing becomes more expensive, interest payments feed back into the budget while companies reconsider the economics of their investment plans. Following that circuit helps explain the proposed 2027 budget and the conditions under which it can be financed. 7 10 12

Documents obtained by Reuters put the proposed defence allocation at RUB 17.1 trillion, against roughly RUB 13.5 trillion in the previous plan for the same year. The revision raises a broader question: how does a sustained military priority draw on resources that still have many other uses? 1

Information available as of 29 September 2026. Figures for 2027 refer to a proposal. The newly reported spending breakdowns come from documents reviewed by Reuters; the underlying annexes could not be accessed directly during this verification.

A revised military priority for 2027

The government’s 24 September announcement, reported by Interfax, envisages federal revenue of RUB 43.3 trillion and spending of RUB 48.8 trillion in 2027. Subtracting those rounded amounts gives a financing gap of about RUB 5.5 trillion. These are Russian government projections, subject to the uncertainties of budget execution. 3

The chart compares the new national-defence proposal with the previous allocation for the same year, 2027, in nominal rubles. SIPRI documents the earlier amount; Reuters reports the new proposal. 1 4

Sources: Reuters, September 28, 2026 and SIPRI, previous plan. Nominal federal national-defence allocations for the same year, 2027, in trillions of rubles. Common zero-based scale. Calculation from rounded amounts: (17.1 / 13.5 − 1) × 100 ≈ 26.7%, or about 27%. The new proposal’s figure remains attributed to Reuters; the original annexes were not directly consulted.

This is a revision of budget planning. It measures neither actual military expenditure in 2026, which remains partly opaque, nor the purchasing power of the allocation. Regional and municipal budgets are outside its scope. 1

The government’s presentation emphasises social commitments, defence and technological development. Assessing the effects on a particular civilian recipient requires programme-level allocations and eventual spending. The aggregate announcements leave that distribution unresolved. 3

Even the military boundary needs care. In its March study, SIPRI estimated broad military spending in the 2026 budget at almost RUB 14.9 trillion, compared with RUB 12.121 trillion under the national-defence heading. Some expenditure connected with the armed forces appears elsewhere in the accounts. This earlier estimate illustrates the classification problem; it is not an additional amount to bolt onto the newly reported 2027 proposal. 4

Oil revenue passes through several filters

Hydrocarbons provide part of the government’s revenue. That makes a simple shortcut tempting: a higher oil price should mean fuller public coffers. Several steps intervene between a price quoted on an international market and money received by the Treasury.

Oil cargo financing traces the commercial steps that precede tax collection.

An exporter earns the price it actually obtains on the volume it sells. Taxes then follow the applicable fiscal rules. The exchange rate also matters because government spending is paid in rubles. The same foreign-currency proceeds convert into fewer rubles when Russia’s currency strengthens. Discounts, lost export volumes and changes in taxation can alter the fiscal result further. BOFIT, the Bank of Finland’s research institute, documents the gap between improved export prices and weak oil-and-gas fiscal receipts in 2026. 5

Refining adds a physical constraint. In its 17 September analysis, the International Energy Agency estimated that Russian refineries processed 3.8 million barrels a day in June. Producing crude and supplying usable fuel are separate stages of an industrial chain. Damage to a refinery can disrupt that conversion and make domestic fuel supply more expensive. 6

The fiscal system also includes a compensation mechanism commonly known as the damper. It reduces the incentive to favour exports when selling fuel abroad would be more profitable than supplying the domestic market. The government compensates part of the difference under the scheme’s rules. The IEA puts subsidies paid to oil companies, including the damper, at RUB 1.5 trillion between April and August 2026. 6

This produces a less straightforward relationship between oil prices and public finances. A high export price can increase some tax receipts while also raising compensation paid to producers. The net effect depends on the formulas, volumes and exchange rate. Actual fiscal receipts, with their accounting scope clearly defined, are therefore more informative than multiplying Brent by a hypothetical production volume. Subsidies and revenue measured over different periods must remain separate observations. 5 6

A second route runs through prices. Dearer fuel raises transport and production costs. Companies can absorb the increase in their margins, pass it on to customers or scale back activity. In its 11 September communication, the Bank of Russia describes the transmission from the fuel shock into costs and inflation expectations. Monetary policy addresses those wider effects; restoring damaged industrial capacity operates on a different timetable. 8

The Treasury can still find buyers

A deficit can be covered through borrowing or by drawing down available financial assets. Russia has, among other resources, its National Wealth Fund. BOFIT put the fund’s liquid component at approximately RUB 4 trillion at the end of August 2026. That is a dated stock of liquid assets within one fund, separate from the full public-sector balance sheet and central-bank reserves. Dividing it by a few months of expenditure to predict an exhaustion date would leave revenue and new financing out of the calculation. 9

Domestic borrowing provides another route. A Russian federal bond, or OFZ, exchanges rubles today for promised future payments. Banks can hold these securities alongside business and household loans. Their decisions depend on returns, risk, liquidity needs and balance-sheet constraints. 10 11 13

Funding difficulties have not prevented all issuance. After the summer’s auction problems, BOFIT reports a successful sale of approximately RUB 1 trillion of floating-rate bonds in early September. That brings in money immediately. The structure of the security then determines how future changes in interest rates are shared. 9

An issuer of an existing fixed-coupon bond knows the contractual interest payments it must make. A floating coupon adjusts to a reference rate under the terms of the instrument. For a bank whose own funding costs can rise with market rates, an adjustable return on an asset can reduce the mismatch between what it pays and what it receives. The Treasury, in turn, retains more exposure to future rates. This is a way of allocating interest-rate risk, with maturity and reset terms also affecting the financing arrangement. 9 12

The central bank can support liquidity through repurchase agreements, or repos. A bank temporarily sells eligible securities and agrees to buy them back, obtaining rubles in the interval. The Bank of Russia’s documentation includes federal bonds among eligible securities, subject to conditions and valuation haircuts. Such an operation provides bank liquidity while the Treasury’s payment obligations remain in place. The sources reviewed do not establish that any particular repo operation financed the September auction. 11

Our analysis of repo and leverage in UK government bonds examines that distinction between liquidity and rate risk in a different institutional setting.

Money then recirculates. When the budget pays a supplier, the recipient receives a deposit in the banking system. Treating finance as a sealed pot, with every ruble lent to government permanently removing one ruble from business lending, misses that circulation. Pressure instead emerges through financing prices, the capacity of balance sheets to carry risk and differences in access to credit. This account describes payment circulation; it does not estimate flows between individual institutions. 11 12

Interest rates return to the budget

On 11 September, the Bank of Russia held its policy rate at 14% a year. That rate anchors monetary policy. A bond or loan also reflects its maturity, risk and contractual terms, so applying 14% directly to the entire government debt stock would produce a fictitious funding bill. 7 12

Timing explains much of the difference. A higher market rate feeds quickly into new issuance. Floating-rate debt adjusts when its contract requires a reset. An existing fixed-coupon bond retains its promised payments, although its market price can change. The budget gradually encounters new financing conditions as it issues additional debt or replaces bonds reaching maturity.

Source: Reuters, September 28, 2026 report republished on September 29. Interest payments as a share of each year’s projected federal spending. Common zero-based scale; the denominator changes between 2027 and 2029. 10.6 − 9.4 = 1.2 percentage points. These are budget projections rather than borrowing rates.

The projected allocation to debt service also rises: 9.4% of federal expenditure in 2027 and 10.6% in 2029, according to Reuters. The denominator is each year’s total spending. These figures describe a budget allocation, not Russia’s borrowing rate. 2

A worked arithmetic example explains the sensitivity without inventing a forecast. For RUB 1 trillion of principal fully exposed for an entire year, one additional percentage point costs RUB 10 billion in annual interest. The result depends on how much principal actually reprices and how long the new rate applies. Estimating the government’s bill would require repayment schedules, the fixed-floating split, coupon benchmarks and projected new issuance.

Gross borrowing and the deficit also answer different questions. Some bond sales replace old debt that must be repaid; others bring in additional financing. Combining the two would overstate the new resources available to fund spending. Here, the RUB 5.5 trillion derived from the 24 September announcement remains the difference between projected expenditure and revenue, rather than a measure of gross bond issuance. 3

Businesses face the same transmission chain

Floating-rate loans bring the transmission closer to the private sector. Approximately 65% of outstanding corporate lending had adjustable rates at the end of 2025, according to BOFIT. That observation concerns business loans at a specific historical date. It indicates the scale of contractual exposure, rather than the current rate structure of all Russian debt. 10

Competition between public borrowing and AI financing raises a related question about credit allocation, involving different markets and borrowers.

Consider a business evaluating a new machine. More expensive financing means the project must generate greater income to cover the same commitment. The business can wait, reduce the project’s scale or seek public support. An existing floating-rate loan can also affect cash flow before the company considers any new investment. This is a financial sensitivity; its practical importance depends on margins, demand and the loan contract.

Subsidised lending can shelter the beneficiary. Depending on the scheme, part of the difference in financing costs is borne by the budget or another participant. Cheap credit for selected borrowers can therefore coexist with demanding terms elsewhere. The Bank of Russia discusses this uneven transmission in its monetary-policy framework. 12

Its September decision also makes the fiscal connection explicit: a larger structural primary deficit in the new budget proposal could require tighter monetary policy than assumed in its baseline. The primary balance excludes interest, while structural adjustments aim to strip out cyclical or temporary components. This is conditional guidance about the fiscal stance; the response would also depend on supply, demand and prices. 7

The chain is then easier to follow. Public expenditure supports activity among its recipients. Where that demand encounters constrained production capacity, price pressure can persist. The central bank keeps monetary conditions more demanding, and exposed borrowers and the budget progressively bear the cost. Part of the adjustment may appear as postponed private investment rather than an immediate reduction in government orders. This is a plausible transmission mechanism consistent with the central bank’s framework, not a stand-alone estimate of how much of any investment decline the war caused. 7 8 12

Uneven constraints across the civilian economy

Several observations need to be held together. BOFIT reports an approximately 10% year-on-year decline in fixed investment in the first half of 2026, citing financing conditions, profits and the completion of earlier large projects. Meanwhile, the Bank of Russia describes corporate lending as still active and labour shortages as gradually easing. These indicators cover different measures and periods, pointing to uneven constraints across the economy. 9 7

The ability to raise funds is the essential counterweight. A government that finds buyers, draws on assets and collects revenue retains room to act. Public orders can also support income and investment among suppliers. The economic question concerns the terms: the financing cost, exposure to future interest rates and alternative uses of the resources involved. 3 9 10

The 2027 proposal signals revised allocations and a greater projected share of spending devoted to debt service. The banking circuit explains how pressure can spread beyond the Finance Ministry. The next decisive evidence will be the final spending breakdown, actual issuance terms and budget execution. Oil prices, fiscal receipts and credit costs need to be tracked separately before being connected using matching periods and definitions. 1 2 5 11

War costs are also distributed through time. Borrowing enables payment today; its terms determine part of tomorrow’s obligations. The relationship between public orders, revenue, banks and interest rates is where part of the burden on the civilian economy takes shape.

Method and limitations

Budget comparisons are nominal and federal. Investment figures are year-on-year changes; fund assets and loan exposures are stocks at their stated observation dates. The interest-rate sensitivity example is explicitly hypothetical arithmetic.

The Bank of Russia is the primary source for its decisions and operating framework, and its assessments are attributed to the institution. BOFIT and the IEA provide outside analysis, while also using Russian statistics for some aggregates. The defence allocations and projected interest shares remain attributed to Reuters; the detailed annexes were not independently confirmed. SIPRI’s study is used solely to explain the broader military perimeter of the 2026 budget.

The detailed annexes of the new proposal were not directly consulted. This analysis therefore does not quantify revisions to social-policy, healthcare or education budgets. September 24 revenue and spending totals are not used to convert subsequently reported interest shares into cash amounts.
