Public debt of the world's third-largest economy grew in the second quarter of 2014 by 1.4% and reached 1039 trillion yen, or about 10.2 trillion USD. Thus, for April-June, Japan's public debt increased by 137 billion dollars. According to forecasts of the Ministry of Finance until March 31, 2015 (the date of the end of the fiscal year in Japan), the amount of debt may rise to 11.2 trillion USD.
It is worth noting that Japan's debt is more than by 3 times bigger than the country's GDP, the highest rate among the G-7 countries.
Growing national debt reduces the attractiveness of government securities, which may adversely be displayed on inflation in the country and lead to a new recession. Despite this in the medium term, the devaluation of the yen is likely to continue, which will stimulate the growth of the stock market.
