In this context, central banks of developed countries have resorted to unconventional monetary policies (UMP) with tools such as quantitative easing, forward guidance, etc. This study examines the impact of the US’s UMP on the financial market and the real economy of Vietnam from 2007 to 2022. As a small, open country that is part of the frontier market group and is increasingly integrating with the world, Vietnam is somewhat affected by the monetary policies of developed countries, especially the US. The event study method examines the stock market's immediate reactions to the FED's official UMP announcements.
