NextFin News - The escalation of the Iran war has sent a violent shockwave through Thailand’s financial markets, triggering a rare "quadruple-tumble" as stocks, gold, bonds, and the baht all collapsed in tandem on March 23. The Stock Exchange of Thailand (SET) index plunged 35.65 points to close at 1,397.34, a 2.49% drop that threatened to breach the psychologically critical 1,300 level. This broad-based liquidation reflects a fundamental shift in investor behavior, as traditional safe-haven logic fails to protect local assets from the combined weight of geopolitical dread and a surging U.S. dollar.
Domestic gold prices provided the most startling evidence of market distortion. Despite the intensifying conflict in the Middle East—a scenario that typically sends bullion soaring—Thai gold prices were adjusted a staggering 106 times in a single day before finishing down by as much as Bt3,950. Gold bars were quoted at Bt66,900, a sharp retreat from January highs. Jitti Tangsitpakdee, president of the Gold Traders Association, described the conditions as "highly abnormal," noting that the traditional inverse relationship between war and gold has been severed by the sheer strength of the U.S. dollar and aggressive selling by major global funds like the SPDR Gold Trust.
The currency market offered no relief. The Thai baht weakened to 33.06 per dollar, its softest level in 10 months. This depreciation is being driven by a "perfect storm" of energy-import anxieties and a hawkish recalibration of U.S. monetary policy. As the war threatens to choke global energy supplies, investors are betting that U.S. President Trump’s administration will face persistent inflationary pressure, forcing the Federal Reserve to keep interest rates higher for longer. This has turned the dollar into the ultimate predator, draining liquidity from emerging markets like Thailand to seek the safety of high-yielding U.S. Treasuries.
Capital flight from the bond market has been equally clinical. In the first three weeks of March alone, foreign investors pulled Bt42.98 billion out of Thai bonds, while net selling in equities reached Bt36.72 billion. The Bank of Thailand has been forced to intervene, selling dollars to smooth the baht’s descent, a move that contributed to a US$4.3 billion drop in national reserves in a single week. With net reserves hitting a 10-week low of US$306 billion, the central bank’s ammunition is being tested by a conflict that shows no signs of a diplomatic resolution.
The immediate future for Thai assets hinges on whether the conflict remains contained or spills into a wider regional conflagration. While some analysts, including Nattapon Chansivanon of UOB Asset Management, suggest that Thai equities remain fundamentally "cheap" at 12 to 13 times earnings, the technical damage is severe. If the SET index fails to hold the 1,350 support level, a slide toward 1,300 becomes the base-case scenario. For now, the "war premium" is being paid not in rising asset prices, but in the rapid erosion of Thai household and institutional wealth as the global flight to the dollar continues unabated.
