Thailand’s economic expansion is projected to gain momentum in 2027 as temporary trade headwinds clear and recent capital investments begin generating industrial output, according to a report by UBS Research.
Thailand’s gross domestic product (GDP) is forecast to grow by 2.8% in 2027, accelerating from an estimated 2.3% in 2026 and exceeding broader market consensus. This acceleration positions Thailand alongside the Philippines as one of the few Southeast Asian economies expected to experience strengthening growth next year.
The projected economic pick-up follows a period marked by a significant import drag, driven by elevated energy import costs, precautionary inventory buildup, and heavy purchases of capital goods for data centers and technology manufacturing. Private investment demonstrated notable strength in 2026, expanding by 13.4% year-on-year in the second quarter, primarily concentrated in machinery, equipment, transport vehicles, and electronics infrastructure such as printed circuit boards and hard-disk drives. As these capital inflows transition into productive capacity, the net export position is anticipated to reverse from a growth drag into a key positive driver.
Statistical recalibrations are also expected to provide an upward adjustment to Thailand’s reported GDP figures. UBS notes that an updated manufacturing production index (MPI)—designed to better capture high-value technological industries—indicated a 4% increase in production output, which could add approximately 0.5 percentage points to headline GDP growth once fully incorporated into national accounts.
Consumer price inflation in Thailand averaged 1.9% in 2026 after rising from -0.1% in 2025, largely driven by global energy price shocks rather than overheating domestic demand. Headline inflation is projected at 2.2% in 2027 and 1.4% in 2028, keeping price growth comfortably within the Bank of Thailand’s (BoT) 1% to 3% target corridor.
Because inflationary pressures remain cost-push in nature, the central bank is expected to maintain its benchmark interest rate at 1.00% throughout most of 2027. Policy normalization is forecast to begin with a single 25-basis-point rate hike in the fourth quarter of 2027, bringing the policy rate to 1.25%, followed by a further increase to 1.50% in 2028 as domestic demand broadens.
Thailand’s current account balance is projected to recover from a 1.5% deficit in 2026 to near balance (0.2% of GDP) in 2027, before expanding to a 1.5% surplus in 2028. The 2026 deficit reflected transient factors, including energy import spikes and cyclical capital goods purchases. External accounts will receive additional support from a gradual recovery in international tourist arrivals, projected to rise from 32.5 million in 2026 to 34.5 million in 2027.
Supported by trade balance normalization and positive capital flows associated with gold market dynamics, the Thai baht is projected to be among the region’s top FX performers, appreciating from 34.0 THB/USD at year-end 2026 to 33.0 in 2027 and 32.0 in 2028.
Across Southeast Asia, aggregate ASEAN-6 economic growth is forecast to remain steady at 5.1% in 2027, compared to 5.2% in 2026. While growth in Singapore and Malaysia is expected to moderate as initial artificial intelligence export surges normalize, Thailand and the Philippines are set to lead regional growth acceleration.
The next structural development for fiscal policy will occur in late May or early June 2027, when the government presents its fiscal year 2028 state budget to parliament. Policy priorities are anticipated to emphasize project execution, infrastructure development, and private sector funding partnerships while preserving long-term fiscal sustainability.
