russia Revising the Budget Rule: Sequestration, Weak Ruble, and End of Oil Buffer

The ministry of finance of the rf is preparing a fundamental revision of the budget rule for 2026–2030, lowering the so-called cut-off price to $45–50 per barrel. Behind the facade of technical adjustments there is the recognition that oil revenues can no longer keep the federal budget afloat.

For decades, the budget rule served as a financial safety cushion for the kremlin: excess oil and gas revenues above the “cut-off price” were directed to the national wealth fund (nwf), smoothing out the volatility of commodity markets. Now the ministry of finance is cutting this mechanism itself – officially to “curb the reduction of nwf assets and reduce pressure on the currency market”.

The real reason is more prosaic: the share of oil and gas revenues in the federal budget is steadily declining – 30% in 2024, 25% in 2025, and less than 20% according to the forecast for 2026. The budget, which for decades had been built around oil rents, is rapidly weaning itself off them – but not by choice.

Every dollar drop in the price per barrel costs the federal treasury about $1.7 billion in oil and gas revenues. The transition to a new “cut-off price” in the range of $45–50 automatically means sequestration – a partial reduction in budget expenditures that will affect both social items and government programs.

In parallel, daily currency intervention volumes will be reduced: according to calculations, by $45.6–79.8 million per day. Without this support, the ruble may fall by 4–7% relative to the baseline scenario.

A weak ruble combined with a budget deficit creates a classic inflationary spiral. For the central bank of the rf, this means there is no room to ease monetary policy: the regulator will be forced to maintain a high discount rate for longer than previous forecasts predicted.

A separate symptom of fiscal stress will be the russian banks’ growing dependence on REPO auctions – a short-term lending instrument of the central bank secured by government securities. The more actively the banking system resorts to this mechanism, the clearer the sign that the system is running out of liquidity.

Lowering the “cut-off price” is not technical optimization. It is moscow’s official recognition that the oil buffer, which had been cushioning fiscal shocks for decades, no longer works as it used to. The budget is being sequestered.
