This paper analyzes the impact on financial markets of purchases of government bonds under the zero lower bound on interest rates. Using data of amount of government bonds purchased by the central banks which are categorized by remaining maturity as reported in Nakazawa and Yano (2014) “Portfolio rebalancing effects of open market operations after the global financial crisis: Evaluation through the construction of the data of purchases of government bonds categorized by remaining maturity,” KIER Discussion Paper Series, Kyoto Institute of Economic Research, Kyoto University (forthcoming, in Japanese), we compare impacts for Japan, the United States, and the United Kingdom. The analysis finds that all three countries had a significant rise in share prices as a result of purchases of government bonds with long remaining maturity by the central banks. The results imply that the quality of capital markets plays a key role in escaping from the global financial crisis.
