Thailand’s Fragile Recovery Faces New Threats Amid PM Suspension and Tariff Tensions
Thailand’s political crisis escalated on July 1 as Prime Minister Paetongtarn Shinawatra was suspended by the Constitutional Court over a leaked phone call with Cambodian leader Hun Sen. While the decision may have temporarily eased protests, it introduces fresh political uncertainty that threatens to derail the country’s already vulnerable economy.
The 7-2 court ruling cooled street tensions, including protests that had drawn tens of thousands, but raised serious concerns among investors about policy stability and prolonged government limbo. These worries come on top of pressure from unresolved US tariffs that already cloud Thailand’s growth outlook.
“This type of court ruling tends to heighten uncertainty around policy continuity,” said OCBC senior ASEAN economist Lavanya Venkateswaran. “The question of government stability needs to be addressed quickly.”
The Thai stock market initially rose nearly 2% following the ruling, likely on hopes of de-escalated unrest. However, those gains faded quickly, with markets ending flat as investors digested the implications of prolonged instability — including stalled Budget approvals, economic stagnation, and the looming threat of a military coup.
Political Crisis at an Inconvenient Economic Moment
Paetongtarn, daughter of former premier Thaksin Shinawatra, faces accusations of jeopardising national sovereignty after a private conversation with Hun Sen about a sensitive border dispute was leaked. Her use of informal language and critical remarks about Thailand’s military commander have deepened concerns, especially given the Shinawatra family’s history of triggering political upheaval — two of which ended in coups.
Thailand’s economy is already grappling with weak domestic demand and sluggish export growth, with GDP expected to expand just 1.6–1.8% this year — among the slowest in Southeast Asia. The political paralysis only adds risk, especially with key government spending potentially delayed and international confidence shaken.
The economic impact of stalled policymaking is serious. After the 2023 election, it took months to form a government, leading to delayed Budget disbursements and only 2% GDP growth that year.
Budget Urgency and Trade Uncertainty
On the same day as the court decision, a new Cabinet lineup was confirmed. Deputy Prime Minister Phumtham Wechayachai is expected to serve as acting PM, while Paetongtarn retains her role as culture minister pending the court’s final decision, which could take up to three months. If convicted, she could face a 10-year political ban, potentially paving the way for Chaikasem Nitisiri to become the next prime minister.
The new Cabinet’s immediate priority is passing the 2026 Budget, critical for sustaining civil service salaries and economic stimulus efforts. “The acting prime minister still has authority to push through the Budget Bill,” said Weerawat Wirojphoka, director at Finansia Syrus Securities.
Meanwhile, external pressures continue to mount. President Trump’s steep “Liberation Day” tariffs — a flat 36% rate targeting Thailand due to its trade surplus with the US — have been paused for negotiations. Thai Finance Minister Pichai Chunhavajira, who remains in his role, is leading a delegation to Washington in hopes of reducing the rate to 10%.
However, the political instability undercuts his negotiating leverage. “If the Thai delegation cannot guarantee implementation of any agreement, that weakens their hand,” said Dr Pavida Pananond of Thammasat University.
A Moment to Rethink Economic Strategy
Beyond short-term trade talks, Thailand’s ongoing challenges could serve as a wake-up call to reassess its industrial and economic strategy. “This isn’t just about tariffs,” Dr Pavida said. “It’s an opportunity to rethink Thailand’s long-term growth model.”
As Paetongtarn’s legal battle unfolds, investors and regional partners are watching closely to see whether the acting government can deliver policy continuity and maintain trade momentum — or whether prolonged turmoil will send Thailand further into economic and political uncertainty.
