Why it matters commercially
Thai SEC policy is a direct input into whether Thailand feels like a deep, investable capital market or a thin retail-led exchange with governance risk. The regulator’s posture on disclosure, digital assets, corporate bonds and ESG determines both compliance cost and investor trust for the companies most exposed to public-market financing.
