What changed
Dated, newest first
- Oil Fuel Fund deficit 103.561bn baht on 18 Oct; more borrowing a last resort because it affects public debt [6]
- Cabinet approved about 1.26tn baht of FY2027 borrowing; PDMO: debt will stay without exceeding the 70% ceiling; average cost about 2.6% [2]
- Officials may seek a Finance Ministry guarantee for new Oil Fuel Fund loans [7]
- Public debt 66.07% of GDP (Feb 2026), about 67.5% (16 Sep, NESDC); framework 68.2% FY2026, 69.4% FY2027, 69.8% FY2028; risk baseline 70.20% FY2028; deficits 4.4% and 3.9% [1]
Why it matters
Thailand's public debt was about 67.5% of GDP in September 2026, against a legal ceiling of 70%. The government's own plan has it at 69.4% in fiscal 2027 and 69.8% in fiscal 2028; one fiscal-risk baseline puts it above 70% in 2028. Officials say they will stay under the cap, but the Finance Minister said in April it could be adjusted if needed, as in 2021.
Why Likelihood 4 Pushes: debt projected just under the ceiling in fiscal 2027 and a risk baseline above it in 2028; the 400bn-baht decree; the Oil Fuel Fund's possible request for guaranteed loans; the 2021 precedent.
Why Impact 5 Key price: 10-year Thai government bond yield. Threshold case: a ceiling above 70%.
The other facts on file (7)
- Ekniti: ceiling could be adjusted if necessary, as during Covid-19; FY2027 budget 3.788tn baht; debt 69.36% by end-FY2027 [3] (23 Apr 2026)
- GDP grew 1.9% in Q2 2026, down from 2.8% in Q1 (NESDC) [4] (17 Aug 2026)
- Cabinet approved a 400bn-baht emergency loan decree [5] (6 May 2026)
- Ceiling raised from 60% to 70% of GDP in September 2021 to make room for Covid-19 measures [9] (May 2025)
- Moody's affirmed Baa1 and moved the outlook to stable [8] (21 Apr 2026)
- Moody's flagged a rising debt burden [10] (21 Apr 2026)
- IMF staff advised against raising the ceiling; adequate ceiling could be as low as 66% once contingent liabilities and extra spending needs are counted [9] (May 2025)

Three scenarios and their signposts
- S1
Under the cap
Tight budgets hold debt just below 70% and it falls after 2029.
- S2
Raise the roof
A new shock or fund guarantees push the committee to lift the ceiling, as in 2021.
- S3
Change the count
The ceiling stays but some borrowing moves off the books, such as fund loans.
| Path | Signpost |
|---|---|
| S1 | A fiscal 2028 budget framework with a smaller deficit |
| S2 | An agenda item on the ceiling at the committee |
| S3 | A guarantee for the Oil Fuel Fund outside the public debt plan |
No probability is given for the three paths.

The other side
Keeping the ceiling would protect Thailand's ratings and keep borrowing costs low [2][8]. The IMF's staff judged an adequate ceiling could be as low as 66% once contingent liabilities and extra spending needs are counted (IMF staff, May 2025) [9]; a credible plan would rebuild room for the next shock.
