Private investment in Thailand tumbled by 3.5% month-on-month in March 2026, reversing a 1.9% gain in the previous month. This marked the steepest decline since September 2025, driven primarily by weaker investment in machinery and equipment. The downturn reflected lower net imports of capital goods, particularly electrical equipment, even as domestic machinery sales increased amid stronger production of machinery and tools. This divergence suggests that while local manufacturing activity remained resilient, firms scaled back on imported capital inputs. Construction investment was broadly stable, with residential construction activity unchanged, while non-residential investment edged lower amid a slowdown in commercial building projects. On the other hand, vehicle investment strengthened, supported by higher registrations, especially passenger cars, as well as increased ship imports by transportation businesses. source: Bank of Thailand

Thailand Investment Tumbles to 6-Month Low
Private investment in Thailand tumbled by 3.5% month-on-month in March 2026, reversing a 1.9% gain in the previous month.

The downturn reflected lower net imports of capital goods, particularly electrical equipment, even as domestic machinery sales increased amid stronger production of machinery and tools. This divergence suggests that while local manufacturing activity remained resilient, firms scaled back on imported capital inputs.

Thailand Private Investment Growth at 4-Month Low
Private investment in Thailand rose 1.9% month-on-month in February 2026, easing from a 2.7% increase in the previous month. This marked the weakest monthly growth since the decline in October 2025, largely driven by a drop in vehicle investment (87.4 vs 91.8), weighed down by lower vehicle registrations, particularly electric vehicles, following the expiration of the EV 3.0 scheme, as well as a fall in aircraft import values. In contrast, investment in machinery and equipment (137.9 vs 131.8) continued to expand, remaining the main driver of overall growth, supported by higher net imports of capital goods, especially computers, despite weaker domestic machinery sales. Construction investment also grew, led by a rise in non-residential projects, reflecting an increase in permitted construction areas, particularly for business and commercial buildings.

Thailand Private Investment Eases in January
Private investment in Thailand rose 2.7% month-on-month in January 2026, easing from a 3.6% increase in the previous month. This marked the softest rise since June 2025, but investment momentum remained broadly positive, with gains recorded across all major categories. Outlays on machinery and equipment continued to expand, supported by higher net imports of capital goods, particularly communication devices and electrical machinery, reflecting ongoing business capacity upgrades. Investment in vehicles also increased, aided by the extension of the EV 3.0 registration deadline through end-January, which encouraged firms to accelerate purchases. Construction activity edged up overall, driven by stronger non-residential building in line with rising permitted construction areas, notably for hotels and commercial properties. However, residential construction weakened, partially offsetting gains in other segments.
