Thai baht (ISO 42 17 code: THB) is the official currency of Thailand, which is issued by the Bank of Thailand, the central bank of Thailand. 1 Thai baht is equal to 100 shadang. The head of King bhumibol adulyadej of Rama IX, Thailand, from the 9-sequence to the 16-sequence, is printed and cast on the front of each Thai baht banknote and coin. On April 6th, 20 18, the Thai baht series with the number 17 was issued, and the banknotes and coins were changed to the head of King Maha Vajiralongkorn of Rama X, Thailand.

At present, there are five denominations of banknotes in Thailand, namely, 20, 50, 100, 500 and 1000, and six denominations of coins, namely, 25, 50 sadang, 1 2, 5 and 10. 1 Thai baht equals 100 Sadang.

1In July 1997, Quantum Fund sold a lot of Thai baht, forcing Thailand to abandon its long-term fixed exchange rate pegged to the US dollar and float freely, thus triggering an unprecedented crisis in Thailand's financial market. After that, the crisis quickly spread to all countries and regions with freely convertible currencies in Southeast Asia, and Hong Kong dollar became the most expensive currency in Asia.

Later, Quantum Fund and Tiger Fund tried to attack the Hong Kong dollar, but the Hong Kong Monetary Authority had a large amount of foreign exchange reserves, and the authorities raised interest rates sharply, which made the hedge fund plan unsuccessful. However, high interest rates caused Hong Kong's Hang Seng Index to plummet by 40%. They realized that shorting the Hong Kong dollar and Hong Kong stock futures at the same time, the former led to soaring interest rates and dragged down the entire Hong Kong stock market, and they were "sure" to make a profit. However, the Hong Kong government intervened in the market in August of 1998, which made hedge funds fail in both the foreign exchange market and the Hong Kong stock futures market.
