Impact is the average of the four parts, rounded, plus one point when Canada is directly hit on two or more channels, up to 10.

What changed

Dated, newest first

  1. Likelihood 5 to 4.
  2. B7 up 0.60 baht to 43.54 baht from 21 Oct; fund deficit 103.561bn baht on 18 Oct; refinery-gate discount of 4 baht ends 31 Oct; five relief measures incl. a 1-2 baht excise cut [1]
  3. Fund deficit about 61.5bn baht on 19 Jul and 92bn on 20 Sep; losses about 700m baht a day; a 100bn-baht facility under study [2]
  4. Diesel 40.69 baht on 18 Sep with 8.62 baht from the fund and a 4-baht refiner discount; cost without them about 54.19 baht [2]
  5. Cabinet approved a 20bn-baht fund facility on 28 Apr; Section 55 transitional subsidy arrangements due to expire 24 Sep; office plans gradual withdrawal of support [3]

Why it matters

Thailand held B7 diesel at 29.94 baht a litre in early March 2026; it was 43.54 baht from 21 Oct, after a string of small rises. The Oil Fuel Fund that holds the price down was 103.6bn baht in deficit on 18 Oct, and its office plans a gradual withdrawal of support. The fund's cost gap was 13.50 baht a litre in September; closing about half of it would take diesel to 50 baht.

Why Likelihood 4 Pushes: fund deficit 103.6bn baht, a plan to withdraw support, borrowing a last resort, refinery discount ends 31 Oct, a 13.50-baht cost gap. Brakes: an excise cut and other relief offered first, a 100bn-baht loan under study, the 2022 guarantee route, truckers' pressure.

Why Impact 5 Key price: B7 retail. Threshold case: 50 baht, up 14.8%.

Three scenarios and their signposts

  1. S1

    Step by step

    Small rises continue as the fund pulls back, and B7 passes 50 baht in 2027.

  2. S2

    Tax for price

    The Finance Ministry cuts the excise by 1-2 baht and the fund borrows, holding diesel in the mid-40s.

  3. S3

    Relief

    World diesel prices fall and the gap closes without a rise.

The signposts of each scenario

The other side

A managed rise would cut the fund's loss and the borrowing it needs. Wider B20 discounts and a push for E20 and B20 could move demand to locally made biofuels, which helps palm and cane growers.
