How are political events reflected in financial asset prices? Break points in sovereign debt prices are analyzed for Denmark, Norway, Finland, Sweden, Germany and Belgium during 1930-1948, using unique data from the Stockholm Stock Exchange. Unlike in countries in-volved in WWII, this market was unregulated. The outbreak of World War II heavily depressed prices of government bonds. Countries which were occupied (Belgium, Denmark and Norway) or under attack (Finland) saw their debt depreciate substantially. The battle of Stalingrad turns out indeed to be a turning-point of the war. This approach represents a complementary quantitative method to analyze the impact of political events.
