1. Auto/EV — Thailand’s automotive production rose 10.93% y/y to 124,646 units in August, while domestic vehicle sales increased 25.59% y/y to 59,809 units. Passenger BEV sales surged 113.29% y/y to 19,721 units, highlighting the continued shift toward electrification. FTI reiterated its full-year 2026 vehicle-production target of 1.45mn units, saying flooding has so far caused limited disruption to automotive plants and supply chains, assuming conditions ease within 2–3 days.

2. Foreign Investors — SET, FETCO and government representatives met 43 global investment firms representing more than US$48tn in assets during recent meetings in New York and London. Investor discussions focused on Thailand’s political stability, Middle East and oil risks, policy continuity and the domestic investment cycle. SET said foreign investors have returned around US$1.5bn to Thai equities YTD following cumulative outflows of more than US$15bn over the previous three years, although Monday’s THB3.94bn net foreign selling highlights that the recovery in flows remains uneven.

3. Tourism / Golden Week — Thailand welcomed 22.67mn foreign visitors through Sep 26, generating approximately THB1.11tn in tourism revenue. Arrivals remain 3.65% below last year, but Chinese arrivals accelerated ahead of Golden Week, providing a potential near-term catalyst for tourism activity as the flood disruption eases.

4. AI / Data Centres — Samsung and five affiliates are investing US$1bn in KKR-backed Helix Digital Infrastructure, which is developing data-centre, power and fibre infrastructure across Asia. The investment reinforces the regional shift in AI infrastructure from data centres alone toward integrated power, grid and connectivity requirements — supportive of our broader view that electricity availability and infrastructure capacity will increasingly determine where the next phase of AI investment is deployed.

5. 2027 Central Budget — Thailand’s public debt is projected to reach 69.7% of GDP by fiscal year 2027 vs. ceiling at 70% fiscal threshold. Under the Public Debt Management Plan for FY27, the government has set new borrowing at Bt1.26trn, alongside an existing debt management allocation of Bt1.91trn and debt service payments totalling Bt5.8trn. The Public Debt Management Office (PDMO) warned that these mounting statutory debt-servicing obligations will severely constrain future central budget flexibility, forcing authorities to implement stricter oversight on state loan guarantees and public investment projects. Note that the public debt/GDP trend rose from 40% (Pre-COVID) to 62.0% (FY 2020), 68.0% (FY 2026) and 69.7% (FY 2027 Projection)

6. Flood Update — The cabinet yesterday approved (1) Emergency Flood Relief size Bt4bn in emergency flood relief following floods affecting more than 2.6m ppl nationwide since mid-Sept. The budget will be allocated from the Central Emergency Reverse Budget for the 2026 fiscal year and (2) Mega Water Management: Approved the long term ‘Chainat-Pa Sak- Gulf of Thailand’ water diversion project with the total project size of Bt165bn spanning across 270km with over 8-years of operational timeline. Current situation is that several medium-size dams are at or close to full water capacity, Kaeng Krachan Dam Phetchaburi (99%), Khun Dan Prakan Chon Dam Nakorn Nayok (98%), Vajiralongkorn Dam Kanchanaburi (96%), Pasak Jolasid Lopburi (96%). Authorities have initiated staged increases in water discharges to manage continuous upstream inflows and maintain structural safety.

7. POLICY — Ekniti pushes “game changer” projects and cross-agency execution. Deputy PM and Finance Minister Ekniti Nitithanprapas has called for Thailand’s 14th National Economic and Social Development Plan to become a more execution-focused framework, concentrating resources on high-impact “game changer” projects and setting clearer measurable targets rather than dispersing efforts across numerous smaller initiatives. He highlighted structural constraints including ageing machinery and an ageing workforce, while calling for government agencies to break down operating silos. Water management was cited as an example where fragmented responsibilities have impeded effective execution. The message reinforces the government’s broader investment-led structural-upgrading agenda, while the current floods underscore the urgency of improving infrastructure resilience and cross-agency delivery.

8. Thai Chuay Thai Plus / Consumption — Phase 1 generated THB172bn of spending over Jun–Sep, reaching more than 26mn people, with over 99% of spending going to small retailers and individual merchants. Phase 2, now underway, expands potential participation to 30.71mn people. However, TDRI questions the programme’s incremental economic impact, estimating a fiscal multiplier of only 0.4–0.9x after accounting for spending that may have occurred anyway. The combination highlights the policy trade-off: meaningful near-term support for household spending and SMEs, but potentially more limited incremental GDP impact relative to the headline spending figure.

9. Flood / Industrial Disruption — Flood disruption is increasingly reaching Thailand’s manufacturing base. The Industry Ministry says 1,315 businesses across 40 provinces have been affected, including 150 factories at AMATA City Chonburi, with 34 temporarily halting production. Separately, Honda will suspend production at its Prachinburi and Ayutthaya facilities from Oct 2–6 as flooding affects employees and commuting. The key watch is whether temporary stoppages broaden into more material production and supply-chain disruption across the Eastern and Central industrial corridors.

10. Data Centres / Power — Thailand’s Data Center Policy Board has agreed to classify data centres into five categories based on electricity consumption, with detailed criteria due next week. The government is also considering two electricity tariffs, with a lower rate for data centres using clean energy versus gas-based power, while incorporating Net Zero requirements into the framework. Officials cited potential data-centre power demand of up to 20GW, versus 26 facilities currently operating. The direction reinforces our view that power availability, grid investment and access to clean electricity are becoming central constraints — and competitive differentiators — for Thailand’s next data-centre investment cycle.

Grok

Weekly briefing for 22 September–2 October 2026. The week was dominated by Bangkok and central-plain flooding, a Constitutional Court ruling that locked in the February election, a sharp drop in the prime minister’s poll numbers, and a late-month SET sell-off driven by foreign outflows and US yields.

Political News

1. Constitutional Court upholds the 8 February 2026 election.
On 28 September the court unanimously found QR codes on constituency ballots, and by 8–1 barcodes on party-list ballots, did not breach ballot secrecy or the Constitution. It still advised against codes that could link a voter to a choice in future polls. The ruling removes the main legal threat to Prime Minister Anutin Charnvirakul’s government. Bhumjaithai won 193 of 500 seats; the People’s Party took 118, Pheu Thai 74 and Kla Tham 58, with the coalition holding more than 290 seats. Sources: Reuters, Thai PBS, JURIST.

2. NIDA Q3 poll shows Anutin’s support collapsing.
Surveyed 18–23 September (2,500 adults), preferred-PM support for Anutin fell from 29.40% earlier in the year to 13.76%. People’s Party leader Natthaphong Ruengpanyawut led at 24.72%. Party support: People’s Party first, Pheu Thai gaining, Bhumjaithai down to 12.08%. The drop tracks flood anger and cost-of-living criticism. Source: The Nation, Thai Enquirer.

3. Kla Tham leaves the opposition whip and is being courted.
After defying an opposition line on the FY2027 budget, Kla Tham was removed from the opposition whip (around 22 September). Thai Enquirer reported on 2 October that bringing its 58 MPs in would strengthen the majority, but Bhumjaithai would likely have to give up its own cabinet seats rather than force Pheu Thai to yield posts. A watch engraved with Anutin’s name, worn by Thammanat Prompao, fed the speculation. Bhumjaithai said on 23 September the coalition was unchanged. Sources: Thai PBS World, Thai Enquirer.

4. Flood visits turn political.
Anutin, also interior minister, toured Khlong Chan and Khlong Prem Prachakorn (27 September) and was heckled (“Too rich”) over food, water and toilets. All 50 Bangkok districts were declared disaster zones. Senate meetings for 28–29 September were cancelled because of the floods. Sources: Khaosod English, Thai Examiner.

5. New DSI chief and Senate-election fight.
Cabinet approved Piya Raksakul as Department of Special Investigation director-general (22 September), drawing criticism over his role on a Senate-election case panel. The Election Commission dismissed a petition by 108 Bangkok Senate candidates alleging provincial-level rigging. The People’s Party said it would file an NACC complaint over alleged Senate-election collusion and flagged a no-confidence debate for October or early November. Sources: Thai PBS World, Thai Enquirer.

6. UNGA81 and the Cambodia file.
In New York on 24 September Anutin called for UN reform and a stronger voice for smaller states, and addressed Palestine and Myanmar. On Cambodia he said Thailand is engaging in compulsory conciliation in good faith but only on maritime delimitation, not land sovereignty, and asked Phnom Penh for a “genuine effort” on border trust, scams and demining. Before departure he said Thailand would field a “full team” if the land border was raised. Conciliation opened in Singapore on 15 September. Sources: Bangkok Post, Khmer Times, Pattaya Mail.

7. Yingluck rice case stays closed.
The Supreme Administrative Court on 23 September rejected a retrial bid in the roughly 10-billion-baht rice-pledging case, finding a Commerce Ministry letter did not justify reopening. Source: The Nation.

8. Royal-defamation convictions and 2010 cases.
On 1 October the Supreme Court sentenced activists Jatupat Boonpattararaksa and Atthapol Buapat to prison over a 2021 Chaiyaphum protest speech. Separately, Red Shirt crackdown cases from April–May 2010 are nearing the 16-year limitation with little progress. Source: Prachatai.

9. NBTC chair sidelined.
The Central Administrative Court on 25 September dismissed Sarana Boonbaichaiyapruck’s suit and found paid medical work disqualified him from the NBTC; the selection committee had already moved to suspend him. Source: The Nation.

Country & Economic News

10. Flood losses concentrated in Bangkok.
Flooding from mid-September, peaking 24–27 September, killed at least eight people and hit more than 580,000 homes across roughly 41 provinces. Nearly 6,000 Bangkok residents were moved to 234 shelters. Loss estimates differ by window and method: University of the Thai Chamber of Commerce about 12.3 billion baht (Bangkok ~7.0 billion, 0.066% of annual GDP, excluding property); Kasikorn Research 7–17 billion baht (0.03–0.11% of GDP); Rangsit University a moderate case of 25.3 billion baht (range 16.9–33.8 billion), or about 0.55% of Q3 GDP, and one scenario cutting full-year growth by 0.3 points toward 2.1%. Q2 growth was 1.9% year on year. Sources: Reuters, The Nation, Khaosod.

11. Second rain wave flagged for 4–8 October.
The Joint Information Center for the flood (1 October) warned of seasonal rain, heavier on 6–7 October in Kanchanaburi and the western provinces and on 7–8 October in Bangkok. Chao Phraya discharge was set to rise toward 2,200–2,500 cubic metres per second; Sing Buri’s Hua Pa was told to evacuate. Governors were ordered to stay in their provinces. Source: The Nation, government briefing via The Standard.

12. Fitch returns Thailand to stable, banks follow.
On 18 September Fitch revised the BBB+ sovereign outlook from negative to stable, citing post-election politics and a debt path expected to stay under 63% of GDP by FY2028 (59.3% in FY2025), versus a prior 65% forecast. It sees a 0.5% of GDP current-account deficit in 2026 (oil and data-centre imports) and a 1.5% surplus in 2027. On 23 September Fitch moved five bank outlooks to stable (KTB BBB+, TTB BBB, EXIM BBB+, SCBT and UOBT A-); BBL stayed BBB stable. Sources: Bangkok Post, Fitch via Kaohoon.

13. August exports up 24.3%, deficit still wide.
Customs exports rose 24.3% year on year (poll 24.9%), after 21.6% in July — a 26-month run and the strongest in 56 months. Imports rose 25.1%; the trade gap was $2.48 billion. US shipments jumped 48.7%, China 15.5%. The commerce ministry tied the run to electronics and AI-related demand and floated about 15% export growth for the year. Source: Reuters.

14. Cost-of-living top-up extended, opposition calls it a flop.
Cabinet extended Thai Chuay Thai Plus by two months, with a 1,000-baht October–November allowance. The People’s Party’s Sirikanya Tansakun called Phase 2 a failure on living costs and stimulus; the government said 40–50 billion baht remains from the original pool. Source: Khaosod, Thai Enquirer.

15. 250-billion-baht water scheme revived.
Anutin said a water-management mega-project shelved after the 2014 coup would go to cabinet, framed as a response to this year’s floods. Source: Thai Enquirer.

16. Migrant status pathway.
A cabinet expedited route has advanced legal status for about 140,000 long-term migrants and children; about 345,000 remain in process, with documentation gaps still blocking rights. Source: Prachatai, 2 October.

Corporate / Company News

17. SCGC–GC petrochemical joint venture near terms.
On 30 September SCG Chemicals and PTT Global Chemical said confirmatory due diligence is underway and key terms — shareholding, steps, synergies — should be set in October. Scope is Thai olefins and polyolefins, including GC’s HMC Polymers stake and SCGC stakes in Siam Polyethylene, Siam Synthetic Latex, Thai MMA and Bangkok Synthetics. GC is expected to be the major shareholder, SCGC significant. PTTGC and SCC rose on 1 October. Source: SCGC, InfoQuest.

18. SET slide and foreign selling.
The index closed the week of 21–25 September at 1,607.63, up 1.48%, helped by the Fitch move. It then fell through 1,600: about 1,602 on 28 September, morning lows near 1,596 on 29 September, and 1,562.83 (−1.97%) on the morning of 30 September, led by banks (KBANK −4%, KTB −4.6%) and DELTA. Foreign investors sold about 15 billion baht in September, including 7.6–7.7 billion on 29 September; retail bought about 16 billion in the month. The 30-year US yield was reported near 5.62%, a multi-decade high. On 2 October the morning session recovered to 1,570.62 (+0.43%). Sources: Kaohoon, Thairath, AIRA.

19. Bank Q3 preview: profit down year on year.
Finansia expects seven covered banks to earn about 55 billion baht in Q3, flat quarter on quarter (−0.7%) and −11.6% year on year. Nine-month profit about 167.5 billion (−5.3%). Q4 is seen as the trough on seasonal costs and year-end provisions. SETBANK at about 1.1x 2026E book, roughly three standard deviations above history; top picks cited were BBL and KTB. Source: HoonVision, 30 September.

20. Thai Airways baggage and flight crisis.
Floods left about 5,600 bags stranded and disrupted about 330 THAI flights. The carrier cut roughly 30% of Bangkok departures for at least three days (Europe, Singapore, Delhi, Kuala Lumpur among them). The air force sent personnel to Suvarnabhumi; Tourism Minister Surasak Phancharoenworakul said the episode hurt Thailand’s image and criticised the airline’s support for deployed soldiers. Source: Bangkok Post, CNA.

21. Webull takes Pi Securities.
Webull completed the purchase of about 99.36% of Pi Securities for roughly $100million(CGHstakeabout91%for~$90 million, plus 8.4%), after SEC approval, with completion dated 31 August and announced in September. It is targeting 200 billion baht in assets under management. Pi has ranked among the top five TFEX brokers. Source: Thailand Business News / PR Newswire.

22. Other tape.
KCE jumped about 10% on 29 September on company news while DELTA lagged. MAJOR’s buyback window (up to 68 million shares / 550 million baht through March 2027) was due to open. PTT’s treasury sale runs through 12 October. GRAND’s bondholder meeting was reset to 7 October; a non-binding Westin asset sale to Rabbit Holdings of up to 494.6 million baht remains on the table. Retail names (CPALL, CRC, home-improvement) were flagged as flood beneficiaries. KPMG’s Q2 M&A review (published September) showed deal value down sharply to $2.1 billion, led by real estate; the largest was TCC/Frasers hospitality restructuring at about $536 million.

Local Market & Social Media Sentiment

English-language chatter (wires, Thai Enquirer, The Nation, analyst notes) treated the week as a governability story: the court ruling stabilised the February result, Fitch’s outlook change was the main positive, and floods were priced as a short GDP hit of well under 0.2% of annual output unless the second rain wave sticks. Market posts focused on US yields, oil, foreign selling of banks, and the SCGC–GC deal as the clearest corporate catalyst. Coalition arithmetic around Kla Tham was framed as a cabinet-seat trade, not an ideological shift.

Thai-language chatter was more immediate and angrier. Dominant tags were น้ำท่วม, evacuations and the Meteorological Department’s warnings; celebrity volunteer posts circulated alongside complaints that water had not drained. Political heat sat on Anutin’s flood visits and the poll crash more than on the barcode ruling, which Thai PBS covered as a legal close rather than a public celebration. Broker accounts (AIRA, Money and Banking) posted mechanical morning wraps — 1,570.62 on 2 October — with little retail euphoria. The gap is tone: English sources stress institutional continuity (court, Fitch, coalition maths); Thai social traffic stresses lived disruption and scepticism that relief spending (Thai Chuay Thai Plus, the revived 250-billion-baht water plan) will arrive before the next rain.

Near-term watch items: Chao Phraya discharge and the 4–8 October rain band; whether Kla Tham actually enters cabinet; foreign flow as US yields stay elevated; October parameters on the petrochemical JV; and any People’s Party no-confidence filing.
