The origins of this statue are uncertain. It is made in the Sukhothai Dynasty style of the 13th-14th centuries, though it could have been made after that time. The head of the statue is egg-shaped, which indicates its origin in the Sukothai period. Given that Sukothai art had Indian influences and metal figures of the Buddha made in India used to be taken to various countries for installation, this suggests the Golden Buddha statue may have been cast in parts in India.

Later, the statue was probably moved from Sukhothai to Ayutthaya, about 1403.
