Research results have found: There is a relationship between banking development and economic growth in terms of trade openness and inflation in Vietnam.; There was an external economic shock affecting the re-lationship between banking development and economic growth in Vietnam in 2008. A threshold value of 32.86% was found and a threshold value of 32.86% was found. of inflation is 9.19%. With a trade openness of less than 32.86%, it shows that banking development does not contribute to economic growth in Vietnam. However, with a trade openness greater than 32.86%, it shows that banking development has a positive impact on economic growth in Vietnam. Meanwhile, with an inflation rate below 9.19%, banking develop-ment has a positive impact on economic growth through domestic credit to the private sector.
