Jasmine flower prices in Thailand have surged to 750–1,000 baht per litre ahead of Mother's Day, driven by reduced supply due to heavy rain and cool weather in major growing regions (Nakhon Sawan, Kamphaeng Phet) combined with seasonal demand spikes. The Department of Internal Trade inspected major Bangkok flower markets and warned retailers against opportunistic price markup, enforcing clear price displays and threatening violators with up to 7 years imprisonment or 140,000 baht fines. The ministry views this as a short-term supply-demand imbalance, not permanent inflation, and urges consumers to compare prices across vendors.
