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.

The Bank of Japan (BoJ) has raised its key short-term interest rate by 25 basis points to 0.5%, marking the highest level since 2008.

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