- Palladium prices surged over 3% to $1,322.69 per ounce, driven by supply fears and escalating tensions between the U.S. and Iran.
- The Thai baht hit a 15-month low of 33.775 per dollar, pressured by a widening interest rate gap and regional instability.

Rubio Warns of "Dangerous Precedent" in International Waters
U.S. Secretary of State Marco Rubio issued a stern warning on Wednesday, stating that the ongoing blockade of key international waterways by Iranian-aligned forces poses a direct threat to the global economy. Rubio emphasized that allowing such actions to go unchecked sets a dangerous precedent that could encourage similar disruptions in other regions, effectively dismantling the rules governing international commerce.
While the U.S. has completed an eleventh consecutive night of strikes against Iranian military infrastructure, Rubio noted that progress in de-escalation is being hindered by a lack of commitment from the other party. Despite the military posture, he reaffirmed that Washington remains prepared to engage in negotiations to seek a sustainable solution to the Middle East conflict.
Palladium Prices Spike Amid Supply Concerns
The precious metals market reacted sharply to the heightening geopolitical risks, with spot palladium climbing more than 3% to reach $1,322.69 an ounce. The rally reflects growing anxiety over potential trade disruptions, particularly as the U.S. considers further sanctions and tariffs on Russian-sourced metals.
Investors are increasingly pivoting toward industrial metals used in the automotive sector as a hedge against supply chain volatility. Analysts suggest that if the conflict in the Middle East continues to impact the Strait of Hormuz, the resulting inflationary pressure could drive palladium and platinum prices even higher in the near term.
Thai Baht Slumps to 15-Month Low
The Thai baht continued its downward trajectory, touching 33.775 per dollar, its weakest level since mid-April 2025. The currency's decline is attributed to a combination of high oil prices increasing Thailand's import bill and a significant yield disadvantage compared to the U.S. dollar.
Market participants are pricing in further tightening by the Federal Reserve, while the Bank of Thailand has signaled it will maintain its current policy rate to support a fragile domestic recovery. This widening interest rate gap, coupled with a 19% U.S. tariff on certain Thai exports, has left the baht vulnerable to sustained selling pressure.
South Korea and ASEAN Seek Unified Response
In response to the escalating crisis, South Korea and ASEAN foreign ministers met in Manila to discuss strengthening regional cooperation. Both parties expressed "serious concern" over the hostilities between the U.S. and Iran, which they warned could undermine global food and energy security.
The meeting focused on advancing a "comprehensive strategic partnership" to safeguard maritime trade routes. As major energy importers, South Korea and Southeast Asian nations are particularly exposed to disruptions in the Gulf, prompting calls for a "complete and immediate cessation of hostilities" across all fronts in the Middle East.
