About Thai gold and how to use this site

What is 96.5% gold and how does it differ from 99.99%?
96.5% gold ("Thai gold") contains 96.5% pure gold by weight; the remaining 3.5% is alloyed for durability and the warm tone Thai jewelry is known for. 99.99% (24K) is internationally-traded pure bullion used in investment-grade bars. Reference prices for both standards are published every trading day, so buyers can compare bullion-versus-jewelry costs side by side.
Why do the buy and sell prices differ?
The buy price (what a shop pays you when you sell to them) is always below the sell price (what a shop charges when you buy from them). The spread covers liquidity, price risk, and operating overhead — typically 100–300 THB per baht-weight for 96.5% gold bars. Jewelry spreads are wider because crafting cost and design premium are baked into the sell-out price.
Why does the price change?
Thai gold prices follow international spot (USD per troy ounce) multiplied by the THB/USD exchange rate. The biggest movers are US Federal Reserve decisions, geopolitical tension, inflation expectations, oil prices, and Thai baht strength. Reference prices are re-published each time these factors shift materially during market hours, which is why our archive often shows several intra-day ticks.
Where does thongnow source its data, and how often does it update?
Every price on this site comes from the public reference data Thai gold shops use to set retail rates. We poll every 5 minutes during market hours (Mon–Sat, 09:00–16:00 ICT) and every 30 minutes overnight. The number shown is the most recent published quote — it is not a prediction or a model output.
Who runs thongnow?
thongnow is an independent project built to make Thai gold-price data easier to access for retail buyers and sellers. We have no affiliation with any gold shop, reference body, or gold-savings provider. The site’s revenue comes from advertising that has no influence on what data we publish.

Can I use this data for investment decisions?
The information on this site is provided for reference and education only — it is not investment advice. Buying or selling decisions are your own responsibility. Before transacting, confirm the live price directly with the shop you’re using; individual shops adjust above or below the reference price based on their own inventory and operating cost.
