Thai Baht Set to Lose More Ground Amid Predictable Oil Shock from Iran Conflict

The Thai baht, which has already been catalogued among the continent’s poorest performers since the outbreak of the Iran conflict earlier last year, is now confronting the prospect of additional depreciation as the war’s associated shock to global oil markets translates into higher fuel costs, a development that has prompted strategists to warn of a further widening of the currency’s losses.

Strategists, whose forecasts have become a staple of regional financial commentary, argue that the currency’s vulnerability is not merely a product of domestic policy missteps but an almost inevitable consequence of a small open economy tethered to volatile commodity pricing, a reality that appears to have been overlooked by policymakers who continue to champion growth narratives without addressing the structural exposure.

The sequence of events, beginning with the Iran war’s ignition of supply anxieties in early 2025, followed by successive spikes in Brent and WTI benchmarks that pushed global oil prices beyond a hundred dollars per barrel, and culminating in the current market sentiment that anticipates further upward pressure, has created a feedback loop that amplifies the baht’s downward trajectory while simultaneously eroding investor confidence in Thailand’s monetary authority.

Yet, despite the clear linkage between external oil price dynamics and the currency’s performance, official responses have been limited to conventional verbal reassurances and modest adjustments to interest rates that, given the magnitude of the price shock, resemble more a token gesture than a substantive policy correction.

This apparent disconnect between the predictable impact of an oil‑driven shock and the tepid policy toolkit underscores a broader institutional gap in which strategic foresight is either absent or deliberately sidelined in favor of maintaining an illusion of stability that the market has already begun to reject.
