Which banks do the four major banks and the twelve major banks refer to?

The terms "four major banks" and "twelve major banks" are specific to the Chinese financial system and refer to its largest state-owned commercial banks by both asset size and systemic importance. The "four major banks," often called the "Big Four," are the Industrial and Commercial Bank of China (ICBC), China Construction Bank (CCB), Agricultural Bank of China (ABC), and Bank of China (BOC). These institutions are distinguished not only by their scale, which consistently places them among the world's largest banks by total assets, but also by their historical roles: each was originally founded to serve a specific sector of the planned economy before evolving into full-service commercial banks. Their status is further cemented by direct state ownership through entities like Central Huijin and the Ministry of Finance, making them fundamental instruments of national monetary policy and credit allocation.

The "twelve major banks" is a broader categorization that encompasses the Big Four and adds eight other significant commercial banks. This group typically includes the Bank of Communications, China Merchants Bank, Industrial Bank, Shanghai Pudong Development Bank, China CITIC Bank, China Minsheng Bank, China Everbright Bank, and Ping An Bank. Some listings may alternatively include the Postal Savings Bank of China (PSBC) within this set, reflecting its vast retail network. This second tier, while still massive, often exhibits more variation in ownership structure, with some having substantial non-state shareholder bases, and demonstrates a greater focus on specific market segments like retail banking, interbank services, or wealth management, leading to more differentiated business models compared to the universal giants of the Big Four.

The operational and economic implications of this hierarchy are profound. The Big Four function as the primary conduits for implementing macro-prudential and sectoral lending policies from the People's Bank of China and other regulators, channeling credit to state-prioritized industries and infrastructure projects. Their deposit bases, drawn from a truly national branch network, provide a stable foundation for the entire banking system's liquidity. The eight other major banks, while also systemically important, often act as competitive catalysts, driving innovation in consumer finance and corporate services, and their performance is a key barometer of commercial banking vitality outside the pure state-core institutions. Together, these twelve entities dominate China's financial landscape, holding a commanding share of total banking assets and deposits.

Understanding this structure is crucial for analyzing China's financial stability and policy transmission. The distinction is not merely academic; it informs risk assessments, regulatory approaches, and market dynamics. The Big Four are treated as pillars of systemic security with implicit full state backing, affecting their funding costs and international credit ratings. The broader twelve-bank group faces closer market scrutiny on profitability and asset quality, though they still benefit from an aura of state support. Any analysis of credit growth, non-performing loan pressures, or financial sector reforms in China must account for the distinct roles and interconnectedness within this defined cohort of major banks.
