Bangkok Business News: Thailand is facing growing warnings that one of its most reliable economic strengths may be fading, raising fresh concerns about the future stability of the baht, investor confidence and the country’s long-term competitiveness.

For more than a decade, Thailand benefited from a strong current account surplus, supported by robust export earnings and a thriving tourism industry. That surplus helped strengthen the baht, build foreign exchange reserves and provide policymakers with significant flexibility during periods of global uncertainty. However, recent trends suggest that advantage is steadily eroding. This Bangkok Business News report finds that Thailand is entering a critical transition in which shrinking surpluses may become the new normal unless meaningful reforms are implemented.

A Key Economic Buffer Begins to Fade

Between 2014 and 2018, Thailand recorded current account surpluses equivalent to roughly 8% to 10% of gross domestic product, largely driven by booming tourist arrivals, particularly from China. The resulting inflow of foreign currency strengthened the country’s financial position and enabled the Bank of Thailand to accumulate substantial reserves.

Since the COVID-19 pandemic, however, that surplus has narrowed significantly. Rising global energy costs have played a major role, especially as geopolitical tensions and conflict in the Middle East have pushed oil prices higher. Thailand’s dependence on imported energy has increased pressure on the trade balance, contributing to widening external vulnerabilities.

Customs data recently showed a trade deficit of around US$10 billion in April, with oil accounting for approximately US$2.4 billion of that figure. While economists believe energy-related pressures may ease if global prices stabilize, they warn that the more serious challenge lies elsewhere.

Rising Imports and Weakening Competitiveness

A growing concern is the increasing reliance on imported products and technology. Over recent months, imports have continued rising as foreign-made goods gain market share against locally produced alternatives. Electric vehicles, advanced technology equipment and imported industrial components are replacing domestic production in several sectors.

Large-scale investment projects are also contributing to the trend. Data centres, for example, often require imported components representing as much as 80% of total investment value. While these projects support modernization and digital growth, they also create additional pressure on the external balance by increasing demand for foreign goods and services.

Economists note that these developments reflect a broader decline in Thailand’s competitive position. The country is facing stronger competition from neighbouring economies that have moved aggressively to attract investment in emerging industries such as artificial intelligence, semiconductors, green technology and advanced manufacturing.

Tourism Recovery Falls Short

Although tourism has rebounded significantly since the pandemic, it has not fully restored Thailand’s external strength. Visitor arrivals have recovered to roughly two-thirds to three-quarters of pre-pandemic levels, yet the services balance remains weaker than expected.

The reason is that Thailand is spending more overseas on transportation, technology services and intellectual property payments. As a result, gains from tourism are increasingly offset by rising international service expenses, limiting the sector’s ability to generate the large surpluses seen in previous years.

This shift has important implications because tourism once served as a powerful counterbalance to economic weaknesses elsewhere. Without that buffer, Thailand faces greater exposure to external shocks and fluctuations in global markets.

Risks to the Baht and Investor Confidence

Economists emphasize that a small current account deficit does not automatically signal a crisis. Thailand still possesses substantial reserves and financial safeguards. However, they warn that a continued weakening trend could reduce policymakers’ flexibility and make the economy more vulnerable.

Forecasts suggest Thailand’s current account could record a deficit equivalent to around 2% of GDP during the second quarter of 2026. While still far below the 7% to 8% deficit levels seen before the 1997 Asian financial crisis, the direction of travel is generating concern.

A shrinking surplus could result in a weaker and more volatile baht. Unlike previous years when the currency generally appreciated, future movements may become less predictable. Greater volatility would complicate monetary policy decisions and potentially increase financing costs across the economy.

Foreign investors are also closely monitoring the situation. Analysts warn that confidence could deteriorate if Thailand simultaneously experiences both a fiscal deficit and a current account deficit, creating what economists describe as a “twin deficit” scenario.

Lessons from Regional Neighbours

Indonesia is frequently cited as an example of the risks involved when external and fiscal balances weaken simultaneously. Investor concerns over policy direction, governance issues and large subsidy burdens contributed to significant capital outflows, currency depreciation and higher interest rates.

Thai economists stress that while Thailand’s situation differs in many respects, the lesson remains relevant. Markets can react quickly when confidence in economic fundamentals begins to weaken.

Building New Engines of Growth

Business leaders increasingly view Thailand’s challenges as structural rather than cyclical. They argue that traditional strengths such as tourism and exports may no longer be sufficient to offset rising costs associated with imported energy, technology and digital services.

To address the problem, experts are calling for the development of higher-value industries capable of generating sustainable foreign income. Healthcare, wellness services, financial services, advanced technology and green industries are among the sectors seen as potential growth engines.

At the same time, business groups are urging authorities to accelerate reforms by reducing regulatory obstacles, tackling corruption, streamlining investment approvals, expanding clean-energy infrastructure and providing clearer long-term policy direction.

Investors today are placing increasing emphasis on policy certainty, governance standards and infrastructure readiness rather than relying solely on tax incentives when choosing investment destinations.

Central Bank Faces Difficult Choices

Most economists expect the Bank of Thailand to maintain current interest rates until at least the middle of next year, assuming inflation remains contained and geopolitical tensions do not worsen significantly.

However, several developments could force policymakers to reconsider. A sharp surge in inflation, aggressive rate hikes by major central banks abroad, or the emergence of a sustained twin-deficit situation could place substantial pressure on the baht and require tighter monetary policy.

Meanwhile, foreign investors continue to watch broader concerns, including economic reform progress, corporate governance standards and political uncertainty. Recent governance controversies involving listed companies have added to investor caution, while unpredictable policymaking remains a recurring concern among international fund managers.

Thailand’s economic warning is therefore about far more than short-term growth figures. It reflects a deeper question about whether the country can adapt quickly enough to a changing global environment marked by geopolitical tensions, demographic pressures, technological disruption and intensifying regional competition. Unless meaningful structural reforms are implemented and new sources of foreign income are developed, the shrinking current account surplus could evolve into a more significant challenge affecting currency stability, investment flows and long-term economic resilience.
