Mega International Commercial Bank Co., Ltd. (Mega Bank) has come into being as a result of the merger of The International Commercial Bank of China and Chiao Tung Bank, effective on August 21, 2006. Both banks have been proud of their longtime histories of outstanding track records in our country.

In 1971, The Bank of China was privatized to become The International Commercial Bank of China Co., Ltd. (ICBC), whose origin dates back to the Ta Ching Bank and its predecessor, the Hupu Bank (the bank under the finance arm of the imperial court in the Ching Dynasty). The Bank of China had been entrusted with the mission to serve as an agent of the Treasury and a note-issuing bank before the establishment of the Central Bank of China in 1928. The Bank of China was designated as a licensed specialized bank for international trade and foreign exchange thereafter. Taking advantage of its specialization in foreign exchange, worldwide network of outlets and correspondence banks, superb bank assets, and excellent business performance, ICBC has become a top-notch bank in the Republic of China.

Set up five years before the founding of the Republic of China, Chiao Tung Bank Co., Ltd. (CTB) had also been delegated to act as an agent of the government coffer and a note-issuing bank in concert with the Bank of China at the outset of the Republic. Transforming from a licensed bank for industries in 1928, an industrial bank in 1975, and a development bank in 1979, CTB turned from a state-controlled bank into a privately–owned one in 1999. It has engaged in loan extensions for medium- and long-term development, innovation and guidance investment (equity investment), and venture capital ever since. For years, CTB has made significant contributions to the improvement of industrial structure and the promotion of the upgrading of industry by assisting in the development of strategic and vital industries in line with the economic policy and the economic development plan of the government.

Building on the professional advantages inherited from The International Commercial Bank of China and Chiao Tung Bank, the Bank leads the domestic banking industry in various areas, including international trade and foreign exchange, international syndicated loans, project financing, and innovative and venture capital. Leveraging the advantage of its global presence and correspondent banks, the Bank has made immense contributions in supporting domestic companies to expand internationally, upgrading industrial, and promoting economic developments. In recent years, by following the footsteps of peers in advanced countries, the Bank is dedicating all efforts to optimizing corporate governance and promoting sustainable development.

By the end of 2024, in addition to Offshore Banking Branch, the Bank has 108 branches (including Foreign Department) at home, and 24 branches, 7 sub-branches, and 3 representative offices (including marketing office) abroad. Together with the network are wholly-owned bank subsidiaries in Thailand, along with their branches, bringing the number of overseas outposts to 39 in total. It has 7,002 employees and an aggregate paid-in capital of NT$96.118 billion.
