Tuesday's session on the SPIMEX exchange closed AI-92 at 75,477 roubles, AI-95 at 75,926 (down 5.29%) and summer diesel at 71,221 (down 3.2%). The split matters more than the record: the grade that rose is the one the region imports in bulk, and the grade that fell is the one Moscow has kept behind an export ban for producers until 30 September.
For the importers the rouble figure is a dollar figure. At the Bank of Russia's rate of 86.38 for 1 September, AI-92 traded at about $874 a tonne, AI-95 at about $879 and diesel at about $825. The exchange price is an ex-refinery domestic print; a delivered Kyrgyz or Tajik contract adds rail and margin on top of it.
That is why decree №579 is the number to hold against it. On 26 August Bishkek extended its fuel subsidy to 31 December and wrote fixed reference prices into the decree: $960 a tonne for AI-92, $1,050 for diesel and $650 for autogas. The Russian exchange print now sits $86 under the AI-92 reference before rail and margin are added; where the delivered contract lands against $960 is what decides the subsidy's cost.
The split matters more than the record: the grade that rose is the one the region imports in bulk, and the grade that fell is the one Moscow has kept behind an export ban for producers until 30 September.
Tajikistan runs the same exposure without the decree: about 90% of its 599,500 tonnes of first-half fuel imports came from Russia by the customs service's count, which is why Dushanbe's request to Iran, reported by CAW on Tuesday, is mostly for crude.
Petrol exports from Russia remain banned to 31 January 2027 for all sellers; the region's contracted tonnes move under intergovernmental agreements, which the 29 August diesel decision exempts by name. The price those tonnes reference went up on Tuesday.
