According to a senior economist at Mizuho Research & Technology, the Bank of Japan raised interest rates to 0.75%, the highest level in 30 years, which could net income of about 800 billion yen a year for households. Naoki Hattori pointed out in a report that this is because banks will raise deposit interest rates, and treasury bond yields will also rise, and the increase will exceed loan interest rates that will increase borrowers' costs. He estimates that raising interest rates on ordinary savings accounts and time deposits would bring the economy about 1 trillion yen in revenue each year.
