Thailand’s car production falls 6.1% as manufacturing recovery remains uneven

Thailand’s car production fell 6.08% year on year to 120,319 vehicles in September, according to figures released by the Federation of Thai Industries on Tuesday, 27 October. The decline followed a 10.93% increase in August, highlighting the uneven recovery of one of Thailand’s most important manufacturing industries. The country remains Southeast Asia’s largest automotive production centre and a major export base for international manufacturers.

There were some encouraging signs beneath the headline production decline. Domestic vehicle sales rose 14.28% year on year in September, following a 25.59% increase in August. Electric vehicles helped support domestic demand, according to the federation’s Automotive Industry Club. Vehicle exports also improved, increasing 4.55% after falling 2.04% in August. These figures suggest that demand has strengthened in parts of the market even though production has not yet returned to consistent growth.

Flooding in September disrupted operations at vehicle manufacturers and parts suppliers, and the industry has been working to restore production. The federation retained its 2026 production target at 1.45 million vehicles, after cutting it from 1.5 million earlier in the year. Whether Thailand can meet that target will depend on production normalisation, export demand, domestic purchasing power and the industry’s ability to adapt to the shift towards electric vehicles. For related coverage, see Thailand Business News: Busines s coverage.

Key points

• September production declined 6.08% year on year to 120,319 vehicles.
• Domestic sales rose 14.28%, while exports increased 4.55% year on year.
• The industry federation maintained its full-year production target at 1.45 million vehicles.

Why it matters: Automotive manufacturing supports a broad network of Thai suppliers, workers and industrial estates. A sustained recovery would help manufacturing activity and employment, but continued weakness in production would highlight the challenges posed by flooding, financing constraints and the transition to electric mobility.

Oil rises above US$115 as reported Saudi refinery attack renews supply concerns

Oil prices rose on Wednesday, 28 October, after Yemen’s Iran-aligned Houthi group claimed responsibility for a missile attack on Saudi Arabia’s largest oil refinery. Brent crude futures increased 1.3% to US$115.36 per barrel, while US West Texas Intermediate rose 1.22% to US$101.12 in early trading. Saudi authorities had not immediately confirmed the reported strike on the refinery, which has a processing capacity of 550,000 barrels per day.

The rebound followed a decline of almost US$2 per barrel on Tuesday, when diplomatic discussions helped ease some concerns about supply disruptions. The latest move demonstrates how sensitive energy markets remain to developments in the Middle East. Even reports of attacks can raise the risk premium built into crude prices when traders are concerned about damage to infrastructure, reduced exports or disruption to shipping routes.

For Thailand, sustained oil prices above US$100 would increase costs for transport, logistics, aviation, manufacturing and other energy-intensive activities. Higher crude prices can also raise the cost of refined fuels and imported feedstocks, while adding pressure to household budgets. Meanwhile, OPEC+ producers are expected to keep their December output targets unchanged at a meeting on Sunday, according to Reuters, although production by several key members remains below target levels.

Key points

• Brent crude rose to US$115.36 per barrel and WTI to US$101.12 in early Wednesday trading.
• The price increase followed a Houthi claim of a missile attack on a major Saudi refinery; Saudi authorities had not immediately confirmed the strike.
• OPEC+ is expected to maintain its December output targets, leaving markets sensitive to further supply disruptions.

Why it matters: Expensive oil threatens to weaken Thailand’s recovery by raising business costs and reducing consumers’ purchasing power. If prices remain elevated, the government could face renewed pressure to balance fuel-cost relief with fiscal sustainability and energy security.

IEA warns Southeast Asia’s clean-energy transition is becoming too dependent on concentrated supply chains

The International Energy Agency warned on Tuesday, 27 October, that dependence on a limited number of countries for clean-energy equipment is emerging as a strategic challenge for Southeast Asia. Speaking at Singapore International Energy Week, IEA Executive Director Fatih Birol said electricity demand across ASEAN is growing at roughly twice the rate of overall energy consumption, driven by industrial electrification, air conditioning, electric vehicles and data centres.

The concentration of manufacturing capacity is central to the concern. China is the dominant global supplier of solar panels, wind turbines, electric vehicles and batteries. According to energy think tank Ember, Southeast Asian countries have spent more than US$20 billion on Chinese-made clean-technology products so far in 2026. These imports can accelerate renewable deployment and reduce the need for fossil fuels, but they also leave the region exposed to changes in trade policy, supply availability and geopolitical tensions.

The energy crisis in the Middle East has strengthened the economic case for alternatives to imported oil and gas. Birol said higher fuel prices have helped accelerate the adoption of solar power, nuclear energy and electric vehicles, while also warning that geopolitical risks will increasingly shape energy markets. For Thailand, the challenge is to expand renewable power and support investment in EVs and energy storage while building a more resilient supply chain, including opportunities in local manufacturing, component production and technical services. Related regional coverage is available through Thailand Business News: ASEAN coverage.

Key points

• Electricity demand in ASEAN is rising about twice as fast as overall energy consumption.
• Southeast Asian countries have spent more than US$20 billion on Chinese clean-energy products in 2026, according to Ember.
• The IEA says concentrated supply chains and geopolitical risks are becoming important energy-security challenges.

Why it matters: Thailand needs affordable, reliable energy to attract investment in advanced manufacturing, EVs and data centres. Diversifying clean-technology supply chains could reduce strategic vulnerabilities while creating opportunities for domestic industry, although developing competitive local production will require investment, skills and scale.

Asian stocks rally on AI optimism as investors await major technology earnings and the Federal Reserve

Asian equities rose on Wednesday as renewed enthusiasm for artificial intelligence lifted technology shares ahead of major US corporate earnings and the latest policy decision from the Federal Reserve. By early Asian trading, MSCI’s broadest Asia-Pacific index excluding Japan had gained 0.85%, Japan’s Nikkei 225 was up 1.2%, and South Korea’s KOSPI had climbed more than 3%. The rally was supported by strong results from chipmaker SK Hynix, which reported a more than sevenfold increase in quarterly operating profit.

Investors are increasingly focused on the companies supplying the computing power behind generative AI. Semiconductor producers and related hardware businesses have benefited from spending on advanced chips, data centres and AI infrastructure. Funding announcements involving major technology companies and news of Anthropic’s planned initial public offering have added to optimism about commercial demand for AI services. The scale of investment, however, has also raised questions about whether future revenues will justify the cost of expanding computing capacity.

The next test comes from earnings due from Alphabet and Microsoft, alongside the Federal Reserve’s policy decision later on Wednesday. Markets widely expect US rates to remain unchanged, but investors will scrutinise policymakers’ guidance as inflation concerns persist and oil prices remain high. For Thailand and the wider region, the rally supports sentiment around technology supply chains, but its durability will depend on actual earnings growth, capital-spending returns and the direction of global interest rates. Related coverage is available through Thailand Business News: Anthropic’s S-1 filing sparks global AI rebound, sending Asian tech stocks soaring.

Key points

• The Asia-Pacific index excluding Japan rose 0.85%, while the Nikkei gained 1.2% and South Korea’s KOSPI rose more than 3% in early trading.
• SK Hynix reported a more than sevenfold increase in quarterly operating profit.
• Investors are watching major US technology earnings and the Federal Reserve’s policy guidance for confirmation that AI investment can generate sustainable returns.

Why it matters: AI-related investment is an important driver of demand for semiconductors, electronics and data-centre infrastructure across Asia. Thailand could benefit from supply-chain investment, but global market volatility and any reassessment of AI valuations could also affect regional capital flows and investor confidence.

Indonesia steps up market surveillance as MSCI warning threatens investor confidence

Indonesia’s equity market has lost approximately 40% of its value in 2026, with more than 6 quadrillion rupiah—about US$330.77 billion—wiped from the Jakarta Composite Index, according to Reuters on Tuesday, 27 October. The sell-off has been driven by concerns following a warning from global index provider MSCI that Indonesia could be removed from emerging-market indexes and assigned standalone-market status if problems with trading transparency and market accessibility are not resolved.

The potential consequences extend beyond short-term share-price volatility. A change in classification could force funds that track MSCI benchmarks to reduce or eliminate their Indonesian holdings, while encouraging other international investors to reassess their exposure. The dispute has focused attention on concentrated share ownership, limited transparency and concerns about coordinated trading. These issues can make it harder for investors to determine whether share prices reflect underlying company performance and whether they can enter or exit positions reliably.

Indonesian authorities are responding with measures intended to strengthen market integrity. The Indonesia Stock Exchange plans to expand the committee that identifies companies with highly concentrated ownership, investigate suspected coordinated trading more proactively and freeze suspicious investor accounts from November. Shares with concentrated ownership are also due to be excluded from the main Jakarta index beginning 2 November. The authorities are engaging with MSCI and other index providers to demonstrate progress on reforms. Related regional market coverage is available through Thailand Business News: Markets coverage.

Key points

• Indonesia’s stock market has fallen around 40% in 2026, erasing more than US$330 billion in market value.
• MSCI’s warning centres on transparency, market accessibility and concerns about coordinated trading.
• Indonesian authorities plan stronger surveillance, investigations into suspicious trading and changes to index eligibility beginning in November.

Why it matters: Indonesia is Southeast Asia’s largest economy, and a prolonged loss of investor confidence could affect regional fund flows and risk appetite. For Thailand, the episode reinforces the importance of transparent ownership, credible market supervision and predictable regulation in attracting international investment.
