In 2020, the Thai auto parts industry will contract along with the auto sector. The OEM market will be hardest hit by the Covid-19 pandemic which had temporarily disrupted the industry’s supply chains in the first half of the year and continues to reduce spending power worldwide. The REM market will see a less severe impact. Demand for REM parts should continue to grow in line with the expanding national vehicle fleet, and decisions to postpone purchases of new vehicles by extending the life of vehicles on the road. In 2021 and 2022, the auto parts industry should recover as the number of vehicles assembled in Thailand is forecast to rise by an average of 3-4% p.a., in step with global vehicle production trends.
However, the industry faces several challenges. There is rising risk of countries raising trade barriers, especially since US authorities accused Thai tire manufacturers of dumping products in the US. The new US-Mexico-Canada free trade agreement which provides for tariff-free trade between the signatories could also have a significant impact on auto parts exports from Thailand to these counties.
Most of the Japanese manufacturers (Table 1) have received some form of support from the government for the manufacture of: (i) parts made from rubber (which depend on domestic production of rubber inputs), including hosing, belts, window seals and tires which are produced through hi-tech processes; (ii) parts for powertrains and engines; parts for an internal combustion engines (ICEs) eat up a third of manufacturing costs. However, the government provides comprehensive support for manufacturers across the length of what are complex supply chains[3], including those which produce radiators, exhaust systems, fuel supply systems, petrol tanks, ignition systems and gearboxes; and (iii) parts for electric vehicles (EVs), for which the government is promoting investment under a comprehensive package[4]. There is a steady stream of applications from auto manufacturers looking to invest in the production of EVs and parts[5], specifically the battery which is a crucial component in EVs and represent over 30% of the vehicle production cost. The government has also introduced measures to promote investment in the assembly of battery electric vehicles (BEVs) and hybrid electric vehicles (HEVs), and companies that have applied for incentives for BEV production are also eligible for the HEV incentives (provided applications had been submitted by December 31, 2019) subject to the following: (i) alongside HEV production, they are required to produce at least 1 major HEV part within 3 years of receiving the investment support and another 4 parts within 3 years of starting HEV production; and (ii) BEV producers need to manufacture 1 major part within 3 years of starting HEV production. The major parts include battery, traction motor, drive control unit (DCU) and battery management system (BMS).
The auto parts market is predominantly domestic and accounts for 60-70% of industry revenue. It is split between parts used in vehicle assembly (OEM market) and the replacement equipment and spares market (REM market).
Receipts from the export of auto parts account for 30-40% of industry revenue, split between OEM products (80-85% of auto parts exports by value) and REM goods (15-20%). The most commonly exported goods are engines, wiring harness, body work, windows, gearboxes, tires and rubber products. Thanks to the extensive and developed supply chains, Thailand’s auto parts industry is able to generate economies of scale. And, coupled with the ability to produce parts that meets auto manufacturers’ specifications, Thai auto parts producers are competitive on world markets. Thailand’s strategic geographical location also allows the country to be an auto parts manufacturing hub for ASEAN zone and other industries6/. These factors have helped Thailand to turn into a major supplier of auto parts globally. In 2019, Thailand was the largest auto parts exporter (by value) in ASEAN zone and 14th in the world. Thailand is the 3rd largest tire exporter in the world, 4th for motorcycle parts (excluding engines or tires), 11th for engines, and 16th for auto parts (excluding engines or tires). The most common destination for these exporters is production facilities elsewhere in the ASEAN zone, including Indonesia, Malaysia, Vietnam and the Philippines, which absorb a combined 25% of exports of auto parts by value. This is followed by the United States (18%) and Japan (10%). However, labor cost in Thailand is higher than in Indonesia and Vietnam, and the level of research & development in the industry is low compared to Malaysia (Figure 3).
The auto parts industry is projected to move in line with the general auto industry. However, from 2012 to 2018, the auto parts market was affected by changes in the economy. That also hurt exports as economies in the major export destinations slowed. However, the industry benefited from investment in/the expansion of production facilities operated by overseas players, especially Japanese companies which use Thailand as a production base to export to assembly lines elsewhere in the ASEAN zone. This helped to support earning growth in the industry. Key points are:
In the first half of 2020, the industry’s MPI tumbled 34.7% YoY because the global Covid-19 pandemic had temporarily halted auto assembly operations and slashed demand for auto parts in the domestic and international markets.
For full year 2020, auto parts output is projected to contract significantly relative to 2019. The global pandemic had forced auto assembly lines worldwide to halt production temporarily in the first half of the year and slashed consumer purchasing power. This had badly affected demand for OEM parts. However, the resilient REM market will help to offset some of the impact. Industry revenues in 2021 and 2022 would also be supported by a recovering economy, which will lift demand for auto parts.
Domestic market: Thailand’s auto parts output is projected to tumble this year but would recover in 2021 and 2022, when the OEM market start to benefit from the recover in the auto sector (Figure 8). Krungsri Research forecasts that for 2020, a 5% fall in global GDP and domestic recession would cause Thai GDP to shrink by 10.3%. Coupled with tighter restrictions for auto loans, these would reduce auto output by 36-37%, the worst in 21 years. For motorcycles, the contraction would be smaller at 24-25% but that would still be a new low. The situation should improve again in 2021 and 2022, and annual output of autos and motorcycles is expected to rise by 3-4%. This would be driven by stronger economic fundamentals and pent-up demand, especially replacement demand for vehicles bought under the First-Car Buyer scheme which would be 8-9 years old. Additionally, several manufacturers which had received investment support for eco-cars and EVs will need to step up production. Against this, the REM market should see steady growth given the 6% average annual growth in the number of vehicles over 5 years old on Thai roads. In this segment, vehicles bought under the First-Car Buyer scheme will be an important market because they would start to need new parts. However, the falling number of cars below-5 years old suggests the accessories market will experience slow growth (Figure 9).
Exports: Export value will fall in 2020 in line with weaker global auto output. But in 2021 and 2022, the direction will reverse. The recovery in the global auto sector will be sustainable and lift auto parts output. The lingering uncertainty over US-China trade relations could also benefit Thailand if trade diversion brings larger orders for Thai manufacturers. Beyond this, manufacturers may respond to this year’s supply chain disruption through improving their resilience to weather future crises by diversifying geographical locations and moving some production capacity to Thailand. If this happens, it would mean the Covid-19 pandemic would effectively strengthen Thailand’s auto parts industry by creating opportunities for manufacturers to improve the quality of their operations and master manufacturing technology, and place them in a better position to expand their export markets.
However, despite the potentially optimistic factors, there are still challenges for the industry. (i) The United States-Mexico-Canada Agreement (USMCA) took effect on July 1, 2020. This means imports of autos between the signatories are now zero-rated when at least 75% of the parts used in these are manufactured in the signatory nations; this could hurt imports of auto parts from Thailand (currently, 21.2% of Thailand’s exports go to these three countries). (ii) The US may implement anti-dumping measures and counter-vailing duties on tires imported from Thailand (current duties are 3.7%). The authorities are considering the situation and would make a decision between November 2020 and May 2021. If the decision is unfavorable for Thailand, Thai exports to the US will suffer and manufacturers based in Thailand may decide to move their operations to another country. (iii) Manufacturers for the REM market (over 1,100 Thai operations, mostly tier-2 and tier-3 manufacturers) could face stronger competition from overseas players which move production to Thailand and tier-1 manufacturers (most of which currently produce goods for the OEM market), to hedge against risk by penetrating the more stable REM market.
Over the long-term, Thai auto parts manufacturers may be hurt by government policies to encourage investment in the production of hybrid and battery electric vehicles. The government is targeting 1.2 million electric vehicles on the road by 2036. However, the domestic market for electric vehicles will grow slowly initially because it will continue to be dominated by hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs). But because these vehicles use standard parts for internal combustion engines (ICEs) alongside their battery-powered components, OEM auto parts manufacturers will not be strongly affected by these developments in 2020-2022. IN the subsequent 4-6 years, the BEVs segment is projected to surge and market share will grow with positive developments in lithium-ion batteries and prices drop12/. In 2010, lithium-ion batteries cost USD 1,200/kWh, by 2020, this would drop to USD 156/kWh. Bloomberg sees the price of BEVs moving close to prices for ICE-powered vehicles by 202213/ (for similar types of vehicles). These growth trends in the BEVs market will be a major turning point for Thai auto parts manufacturers, which will need to adjust to a rapidly-changing industrial landscape. The industry had been focusing strongly on developing the supply chain for internal combustion engines, but as BEVs become more popular, the number of parts by required auto manufacturers will shrink. The typical BEV drivetrain has about 20 parts compared to over 2,000 in an ICE vehicle. In BEVs, the battery - rather than the engine - will be the major component and is expected to consume up to 30% of total production costs for a BEV.
There have been rising investment in Thailand to produce auto parts for EVs, especially batteries. These include the development and production of a nickel-metal hydride battery by Toyota and a lithium-ion battery by BMW. And, as the EV market matures, it will affect demand for a wide range of OEM parts, including engines, radiators, exhaust systems, fuel systems, petrol tanks, ignition systems and gears. But there will still be demand for products such as suspension, body work, lighting systems and interior fittings. Some BEVs also use electronic control systems to reduce wear on parts (e.g. tires and brake pads). Future automated driving systems will also be safer and reduce the number of accidents, which would mean lower demand for REM parts.
In the coming period, EVs will play an increasingly important role in the Thai auto industry. This will reshape the industry’s supply chains which are currently structured in a strictly linear fashion. Orders filter through in a fixed direction through the layers in the auto parts industry (Figure 11). They include: (i) Tier 1 suppliers, which produce goods that meet the quality set by the major auto manufacturers, allowing them to supply to these players directly; (ii) Tier 2 suppliers, which supply parts to Tier 1 producers and may benefit from technology transfer, and (iii) Tier 3 suppliers are small outfits that supply to Tier 1 and Tier 2 players. Navigating the linear supply chain is cumbersome and it can take a long time for an order to percolate through the levels. To respond to just-in-time delivery, it is often necessary for suppliers to maintain high stock levels, making this type of operation suitable only for mass auto production where only economies of scales can justify involvement. However, the manufacture of EVs are more dependent on robotic and automated production lines (to ensure precision) and the use of hi-tech end-user products. They include automatic driver assistance, automated impact detection sensors, automatic speed controllers and on-board systems that connect with online data. They are required to create a smooth travel experience, for example by collecting data on weather, road and traffic conditions, or downloading relevant maps. In future, this will also extend to continually improve automated driving assistance (Figure 12). Because of these differences, the EV supply chain often diverges markedly, taking a circular, networked form rather than a straight line from start to end (Figure 13). The network would comprise auto parts suppliers, device manufacturers, telecom companies, online players and IT suppliers. The participants have a non-hierarchical relationships with each another, which helps to accelerate production and gives greater flexibility. Supplier would not need to maintain excessive stock. As a result, the system is better able to respond to a wider range of needs.
Alike elsewhere in the economy, the Covid-19 pandemic and resulting drop in spending power in Thailand and worldwide will slash revenue in the auto parts industry in 2020. Demand for OEM parts would drop but that would be partly compensated by resilient growth of the REM market along with a rising number of vehicles on Thai roads. In 2021 and 2022, the situation should start to recover as economic activities return to normal and lift demand for auto parts.
