The Bank of Japan raised its key interest rate to about 0.5% from 0.25% Friday, noting that inflation is holding at a desirable target level. The decision by the central bank came at the end of a two-day policy board meeting in Tokyo.

Japan's central bank has increased the cost of borrowing to its highest level in 17 years, after consumer price rises accelerated last year. The move by the Bank of Japan (BOJ) to raise its short-term policy rate to 0.5% comes just hours after the latest economic data showed prices rose last month at the fastest pace in 16 months.

The Bank of Japan raised interest rates on Friday to their highest since the 2008 global financial crisis and revised up its inflation forecasts, underscoring its confidence that rising wages will keep inflation stable around its 2% target.
