Army chief Prayuth Chan-ocha has resigned as a board member of Thai Military Bank (TMB) in a decision effective Thursday, the bank said.
In a filing to the Stock Exchange of Thailand, Agapol Na Songkhla, head of strategy and transformation and the bank's secretary, said Gen Prayuth had decided to step down from the 16-member board.
But the filing did not explain why he had made the decision.
The army holds a 1.25% stake in the listed bank with the Finance Ministry as the major shareholder.
The junta, led by Gen Prayuth, is aiming to improve state-owned enterprises plagued by political interference. Board members at several enterprises, including Airports of Thailand, PTT, Thai Airways International and the Port Authority of Thailand, have stepped down to let the National Council for Peace and Order hand-pick new members.
