Kuroda also raised the official assessment of the economy, as the economic growth in the first quarter was faster than previously thought and the current account surplus showed a rapid growth. Japanese policy makers stuck with April's pledge to increase the monetary base by 60 to 70 trillion Yen per year, and on Tuesday Kuroda mentioned the BoJ has more scope to increase its purchases of exchange-traded funds than of the nation's real-estate investment trusts. He also said that 3.15 trillion Yen a year in a form of loans will be extended to 70 major and regional banks on June 20 through a programme introduced by former Governor Masaaki Shirakawa.
