Now the Bank of Japan put an end to its five-year-old ultraloose policy, the biggest concern for most people is how the change will affect them.

Analysts are anticipating the BOJ will raise the overnight call rate -- a benchmark for short-term interest rates -- by the end of the year. They have admitted that their own speculation might spur the financial market and cause medium- and long-term interest rates to rise slowly.

A positive aspect of a rise in rates will be an increase in interest on deposits. This will be welcome news for bank-account holders who have been getting scant interest income on their money.
