Historically, the Strait of Hormuz has been a focal point of strategic importance, dominated by Iran and Saudi Arabia, and frequently subject to tensions over oil transit. Following the 1973 Yom Kippur War, the Strait became a critical choke point, dramatically impacting global oil prices and shaping international relations. Similarly, the Taiwan Strait is defined by the ongoing strategic rivalry between China and the United States, a conflict with significant implications for global trade, particularly semiconductors, and a complex history of political autonomy claims. The Strait of Malacca, vital for energy shipments and transshipment between the Indian and Pacific Oceans, faces potential disruptions due to heightened naval presence, piracy, and underwater mining activities. The 2021 incident involving a suspected Chinese submarine traversing the Strait highlighted these vulnerabilities.
Key stakeholders include Thailand itself, of course, alongside major regional players such as China, the United States, Saudi Arabia, Iran, Indonesia, and Malaysia. China’s assertive claims in the South China Sea and its increasing naval capabilities directly impact the Malacca Strait, while the US maintains a significant naval presence in the region, ostensibly to counter Chinese influence. Saudi Arabia’s control over the Strait of Hormuz provides it considerable leverage. Within ASEAN, Indonesia and Malaysia, possessing significant maritime trade, represent key partners in addressing the evolving strategic landscape. According to a recent report by the International Crisis Group, “the confluence of rising geopolitical tensions and economic vulnerabilities creates a scenario where Thailand, as a strategically positioned ASEAN member, faces considerable operational and political risks.” (ICG, “The Straits Under Strain,” January 2026).
Data from the World Bank indicate that maritime trade accounted for roughly 80% of Thailand’s total exports in 2025, highlighting the direct dependence on the uninterrupted flow of goods through these chokepoints. Furthermore, a 2025 study by the Siam Analytics Institute projected a potential 15-20% drop in Thailand’s GDP if the Strait of Hormuz were to experience a prolonged disruption, demonstrating the potential scale of economic damage. “The interconnectedness of global trade means that a crisis in one key maritime artery can quickly cascade across the entire global economy,” noted Dr. Sorasich Swangsilp, lead researcher at ISIS, during the webinar. “Thailand’s vulnerability is not simply about logistics; it’s about systemic risk.” This vulnerability is further exacerbated by the rising incidence of cyberattacks targeting port infrastructure and maritime logistics systems, presenting a new dimension to the security challenges.
The webinar on 15 May 2026, organized by the Ministry of Foreign Affairs and ISIS, underscored the need for proactive analysis and strategic preparedness. Participants, including Professor Pailin Kittisereechai of Kasetsart University, emphasized the importance of diversifying trade routes and strengthening domestic industrial capacity to mitigate reliance on vulnerable maritime supply chains. Dr. Kittipos Phuttivanich from Ramkhamhaeng University highlighted the necessity of investing in enhanced maritime security capabilities, including advanced surveillance technology and coordinated defense strategies. Dr. Nat Tharnpanich’s research pointed to the crucial role of diplomatic engagement and multilateral cooperation in managing tensions and promoting stability in the region. “Thailand’s leverage within ASEAN provides a unique opportunity to advocate for rules-based maritime order and encourage dialogue among key stakeholders,” he stated.
Short-term outcomes (next 6 months) are likely to see continued escalation of naval activity, increased insurance premiums for ships transiting the contested straits, and heightened volatility in global energy markets. Further disruptions to supply chains are almost guaranteed, leading to inflationary pressures and potential economic instability. Long-term (5-10 years), the scenario could involve a more fragmented global maritime order, with multiple regional power blocs vying for control of critical chokepoints. Thailand’s ability to adapt – through strategic alliances, enhanced defense capabilities, and investment in resilient infrastructure – will be paramount. “The key for Thailand isn’t to pick sides in the great power competition, but to build its own strategic independence and contribute to a more stable and predictable international maritime environment,” argues Dr. Sorasich Swangsilp. A significant shift in global trade patterns, potentially favoring alternative routes and trade partners, is also a plausible outcome.
Looking ahead, Thailand’s response must prioritize diversification of its trade partners, bolstering its maritime security capabilities, and proactively engaging in regional diplomacy. Strengthening relationships within ASEAN, particularly with Indonesia and Malaysia, is crucial for collective action. The government must also invest in developing alternative logistical hubs and strengthening domestic industries to reduce reliance on vulnerable supply chains. Ultimately, Thailand’s strategic response to the evolving maritime security landscape will not only safeguard its own economic future but also shape the dynamics of regional stability. The challenge facing Thailand is whether its current defensive posture will prove sufficient or if a more assertive strategic framework is required. This requires a serious, ongoing dialogue within Thailand and across ASEAN about its role in a world increasingly defined by maritime competition and potential instability.
