1. Mongolia and Rio Tinto Sign Oyu Tolgoi Amendments, Target 2027 Dividends
Mongolia and Rio Tinto signed amendments to the 2011 Oyu Tolgoi Shareholders’ Agreement after negotiations that began in August 2025, the first changes in 17 years. The government estimates MNT 30 trillion in projected cost reductions, including MNT 8 trillion in management and duplicate costs and MNT 22 trillion in shareholder-loan interest. The loan rate falls from SOFR plus 6.5% to SOFR plus 4.0%, and reviews move from seven-year to three-year intervals. The parties will work toward 2027 dividends, but their amount and structure remain unsettled.

2. Bank of Mongolia Keeps Policy Rate at 12.5%
The Bank of Mongolia kept its policy rate at 12.5% after its September 16-17 extraordinary meeting, judging that high inflation constrained rate cuts while further tightening could weaken activity and burden households and businesses. August annual inflation was 12.5% nationwide and 11.6% in Ulaanbaatar, above the 3%-7% medium-term target; core inflation was 6.8%. Fuel, energy and global food prices, budget spending and wage growth remain risks. First-half growth reached 7.7%, led by mining and transport, while non-mining activity stayed weak.

3. Mongolia Negotiates to Buy 1 Million Tonnes of Chinese Fuel Annually
Mongolia is negotiating to buy one million tonnes of petroleum products a year from PetroChina, about one-third of annual national consumption of roughly three million tonnes, Industry and Mineral Resources Minister G. Damdinyam said. Talks produced an offer for regular supply and continue over a market-based price formula; no supply contract has been completed. Separately, China National Petroleum Corporation is set to supply 10,000 tonnes of motor gasoline and 7,000 tonnes of jet fuel and diesel this month. Mongolia has not yet built reserves and may need to shift from Russian Euro 2 fuel toward higher-cost Euro 5 fuel.

4. Orano Expects Zuuvch-Ovoo Mine to Produce Millions of Pounds by Decade-End
Orano expects its Zuuvch-Ovoo uranium project in Mongolia to produce several million pounds annually by the end of the decade, chief executive Nicolas Maes said at the World Nuclear Symposium 2026 in London. Maes said the mine could be the next major project with the greatest impact on the global uranium market. The project entered construction earlier this year after years of work with the Mongolian government; it is not yet producing. Maes said its investment agreement received 79% parliamentary support.

5. Fiscal Stability Council Flags Risks in Proposed 2027 Budget
The Fiscal Stability Council said the proposed 2027 budget formally meets four of six statutory fiscal requirements but poses structural risks. The reports put expenditure at MNT 43.5 trillion or MNT 43.6 trillion and the council’s assessment at 37.8% of GDP, above the 30% development-guideline target; debt is put at 50% of GDP. The supplied reports conflict over whether MNT 3.5 trillion in dividends includes Oyu Tolgoi and state-owned companies or state-owned companies alone. Separately, MNT 2 trillion in projected Oyu Tolgoi dividends is allocated to 52 investment projects.

6. Economy Committee Discusses Proposed $450 Million ADB Financing Framework
Parliament’s Standing Committee on Economy discussed on September 16 a proposed $450 million financing framework with the Asian Development Bank, following cabinet review on August 19. The package combines $200 million in budget support, including $50 million on highly concessional terms, with a $250 million contingent disaster credit line. Finance Minister Z. Mendsaikhan said it would cushion the budget and balance of payments from external shocks and enable rapid financing during disasters, crises, or energy and food-supply disruptions.

8. Rosneft’s Ryazan Refinery Halts After Ukrainian Drone Strike
Rosneft’s Ryazan refinery halted operations after a Ukrainian drone attack stopped its CDU-6 and CDU-4 crude-processing units. CDU-6 caught fire and can process 8 million tonnes a year, or about 160,000 barrels a day—nearly half the refinery’s capacity—while CDU-3 has been under repair since mid-May. Repairs to the damaged units are expected to take several weeks. The disruption is relevant to Mongolia because of the country’s high dependence on Russian fuel supplies; separate reporting says wider diesel constraints are expected to persist into next year.

9. Planned Airport Expansion Awaits Parliamentary Loan Approval
Mongolia and Japan have reached an agreement to expand and upgrade Chinggis Khaan International Airport, but the government-backed draft loan agreement still requires parliamentary approval before preparatory work can begin. Expansion is planned to start in 2027. The reported financing is another 65 billion-yen concessional loan, with media in both countries reporting about MNT 1.5 trillion at 0.1-0.2% interest over 40 years. The airport was designed for 1.5 million annual passengers, while summer tourism and passenger growth have strained capacity.

10. Officials Warn Three Provinces Could Face Power Restrictions Without S-458 Upgrade
Officials warned during a September 12 winter-preparedness visit to Ulaangom substation that electricity supplies to Uvs, Khovd and Bayan-Olgii could be restricted unless capacity on the S-458 transmission line importing power from Russia is increased. The 110 kV single-circuit line, commissioned in 1995, has 40 MW installed capacity and is operating at its agreed 50 MW limit; emergency capacity is 55 MW under an arrangement with Tuva Energy. Officials also proposed replacing 31-year-old transformers and raising substation capacity from 2x10 MVA to 2x25 MVA.
