The Short Version
BIDV's 1957 founding, well-documented by government and industry sources, makes it older than all major Vietnamese commercial banks, including Vietcombank (1963), Vietinbank, and Agribank (both 1988). The phrase "one of the oldest" is defensible. However, the State Bank of Vietnam was founded in 1951 and is officially recognized as the country's oldest banking institution. BIDV's own marketing sometimes overstates its position by claiming to be "the oldest financial institution," which is inaccurate.
