The Bank of Thailand

There is one to rule them all! The Bank of Thailand is the Kingdom's central bank and governs all the rest.

Established in 1942, the Bank of Thailand is the agent that deals with international financial markets and organizations, as well as the central banks of other countries. 

Internally, the Bank of Thailand helps manage the entire country's economy with the Ministry of Finance.

Together they give a lot of independence to individual businesses, focusing instead on creating and sustaining an economy of growth.

The Bank of Thailand issues the Thai baht (THB). Like many currencies around the world, it was originally a unit of weight of silver or gold.

Law and regulations:

According to Section 4 of the Financial Institution Business Act, B.E. 2551,financial institution business” can engage in corporate banking. Some of them are:

  • "Commercial bank" provides a full range of services for all types of customers, except for insurance underwriting, brokerage, trading, and underwriting securities.

In keeping with the Thai population at the time, the Bank focused on helping farmers. Back then, it was known as Thai Farmers Bank.

As the country's economy grew, so did Kasikorn.

When the rapid expansion of the 80s and 90s led to the economic crisis of 1997, Kasikorn responded with its "Reengineering Policy" which helped it get through and eventually thrive again.

The very first ATMs in Thailand were SCB-issued. 1983 was a good year!
