<abstract xmlns="http://www.w3.org/1999/xhtml">This paper evaluates the impact of external financing on market risk for the listed firms in Vietnam`s banking industry, especially during and after the financial crisis 2009-2011.First of all, by using quantitative and analytical methods to estimate asset and equity beta of total 9 listed companies in Vietnam banking industry with a proper traditional model, we found out that the beta values, in general, for many institutions are acceptable.Second, under 3 different scenarios of changing leverage (in 2011 financial reports, 30% up and 20% down), we recognized that the risk level, measured by equity and asset beta mean, decreases when leverage increases to 30% and increases more if leverage decreases down to 20%.Third, by changing leverage in 3 scenarios, we recognized the dispersion of risk level, measured by equity beta var, increases from 0,108 to 0,181 if the leverage increases to 30% whereas decreases to 0,073 if leverage decreases to 20%. But the dispersion measured by asset beta var decreases to 0,007 (leverage up 30%), showing leverage impact. Finally, this paper provides some outcomes that could provide companies and the government with more evidence in establishing their policies in governance.</abstract>
