The Bank of Japan's total assets stood at ¥156.36 trillion as of the end of November, reaching a record high for the first time in almost seven years.
Total assets rose above ¥13 trillion from a year earlier due to increased purchases of government bonds in line with bolstered monetary easing measures, accounts showed Tuesday.
The previous record of ¥155.61 trillion was logged at the end of 2005, when the government was taking quantitative easing measures. Such steps target the amount of money supplied in the market rather than interest rates.
