The gold price today in Thailand is not quoted the way most of the world quotes gold. Instead of US dollars per troy ounce of pure gold, Thai shops quote baht currency per baht weight of 96.5% gold, and they take their lead from a daily reference price published by the Gold Traders Association. If you want a 1 gram gold price in Thailand, or want to compare a Thai price with the international market, you need to convert between the two systems.
This guide explains the units, the reference price and the conversions step by step, using clearly labelled hypothetical figures. It does not give live prices; for the international spot price, see our gold price page. If you are a Thai goldsmith or manufacturer looking for raw gold, see our page on buying gold in Thailand.
The Baht Weight: Thailand’s Unit for Gold
In Thailand, “baht” is both the currency and a unit of weight for gold. The conventions are slightly different for bars and ornaments.
- One baht of gold bullion (bars) weighs 15.244 g.
- One baht of gold ornaments (jewellery) is conventionally about 15.16 g.
- Smaller amounts are often quoted in fractions of a baht, while larger amounts are quoted in multiples.
Why the distinction matters
Because ornaments use a slightly lower weight per baht, one baht of jewellery contains a little less gold than one baht of bars. When comparing prices, always check whether a figure refers to bars or ornaments, and whether it is a buying or a selling price.
The 96.5% Standard
Thai gold bars and ornaments are traditionally made at 96.5% purity, a little higher than 23K (95.8%) and below 24K. This standard gives the rich colour Thai buyers expect while being slightly harder than pure gold.
International bullion is usually 99.99% pure. So a Thai baht-gold price and an international spot price are not directly comparable until you adjust for purity as well as weight and currency. Our article on how raw gold is valued sets out the same purity arithmetic for other karats.
The Gold Traders Association Reference Price
Thailand’s Gold Traders Association publishes daily reference buying and selling prices for 96.5% gold bars and ornaments, and updates them during the day when the international price moves. Shops across the country price from this reference. Because the reference can change several times on a busy day, the price you see in the morning may not be the price at closing, and a quote is generally only valid at the moment it is given.
- Bar selling price: what a shop charges you per baht of 96.5% bullion.
- Bar buying price: what a shop pays you per baht of 96.5% bullion. The gap between the two is the spread.
- Ornament buying price: what a shop pays per baht of used jewellery, usually lower than the bar buying price.
- Ornament selling price: the reference for jewellery, before the making charge that is added on top.
What moves the Thai price
Two things drive the reference price: the international gold price in US dollars and the baht’s exchange rate against the dollar. Unlike pegged currencies, the baht floats, so the Thai gold price can move even on a day when the dollar gold price is flat.
Converting the Thai Price to a 1 Gram Gold Price
To turn a baht-weight price into a price per gram, divide by the weight of one baht. To express it per gram of pure gold, also divide by 0.965.
- Price per gram of 96.5% gold = price per baht ÷ 15.244 (for bars).
- Price per gram of pure gold = price per gram of 96.5% gold ÷ 0.965.
- Price per baht of 96.5% bars from an international price = price per gram of pure gold in THB × 0.965 × 15.244.
A hypothetical example
The figures here are hypothetical and are not today’s price. Suppose the bar selling price were THB 40,000 per baht. One gram of 96.5% gold would cost about THB 2,624 (40,000 ÷ 15.244), and the equivalent price per gram of pure gold would be about THB 2,719 (2,624 ÷ 0.965).
Working the other way, assume a hypothetical spot price of USD 2,500 per troy ounce and a hypothetical exchange rate of THB 35 per US dollar. Pure gold would then be worth about THB 2,813 per gram, and one baht of 96.5% bars about THB 41,383 before any local premium or spread. Comparing a calculation like this with the reference price shows you how much local premium or discount is built in.
Making Charges on Thai Jewellery
Thai jewellery is sold by weight at the day’s ornament reference price plus a making charge for the craftsmanship. On traditional designs such as chains, bangles and rings, making charges are relatively low, which is one reason gold jewellery is a popular way to save in Thailand.
When you sell jewellery back, you will usually receive the ornament buying price, which is below the bar price, and the making charge is not recovered. If you are buying mainly as savings, compare the total cost of jewellery with that of bars.
Using the Price as a Goldsmith or Manufacturer
For workshops, the reference price is also the benchmark for raw material. High-purity gold such as 99.9% dust or 99.99% bars has to be alloyed down to 96.5% before it becomes baht gold, and that is straightforward for a goldsmith. Natural 22–23K nuggets are below 96.5% and need refining before they can reach the local standard.
To compare an imported quote with the local reference, convert both to the same purity, weight and currency using the formulas above. A known starting purity, backed by an independent assay, reduces losses and helps a workshop avoid pieces that fall below 96.5%. Our guide to verifying gold purity explains how to read an assay certificate.
VAT, Imports and Storage
Thailand applies VAT to most goods, but gold bullion is treated favourably, while ornaments and other gold products can be taxed differently. Import duty, VAT treatment and declaration requirements depend on how the gold is classified and change from time to time, so confirm the current rules with a Thai customs broker and tax adviser before each shipment.
Thai gold culture is built on holding physical gold at home or turning it into jewellery rather than on professional vaulting, so think about secure storage and insurance before buying larger amounts. Keep receipts from the shop, which normally record the weight in baht, the purity and the price paid; they make reselling simpler and help settle any dispute about what was sold.
Raw Gold for Thai Workshops
YNM Gold Sellers supplies 99.9% gold dust that can be alloyed directly to 96.5%, along with 99.99% bars in 1 oz and 100 g and natural 22–23K nuggets for refiners. Our products are not 96.5% baht gold; they are higher-purity raw materials for workshops to alloy. Each lot comes with an independent third-party assay certificate and chain-of-custody documentation, and ships under insurance.
Frequently Asked Questions
How many grams are in one baht of gold?+
One baht of gold bullion weighs 15.244 g. Gold ornaments use a slightly lower convention of about 15.16 g per baht.
How do I calculate the 1 gram gold price in Thailand?+
Divide the price per baht of 96.5% bars by 15.244 to get the price per gram of 96.5% gold. Divide that by 0.965 to get the price per gram of pure gold.
Who sets the gold price in Thailand?+
The Gold Traders Association publishes daily reference buying and selling prices for 96.5% gold bars and ornaments, updated during the day as the international price and the baht exchange rate move.
Why is Thai gold 96.5% and not 99.99%?+
96.5% is Thailand’s traditional standard for gold bars and ornaments. It gives a rich colour and is slightly harder than pure gold, which suits jewellery and everyday handling.
Why does the Thai gold price change when the world price does not?+
The baht floats against the US dollar, so changes in the exchange rate move the Thai gold price even when the dollar gold price is unchanged.
