Bank of Japan's Unexpected Rate Hike Signals Potential for Further Increases

Analysts question the central bank's optimistic economic outlook as board members discuss higher future rates.

The Bank of Japan raised its short-term policy rate to 0.25%, the highest in 15 years.
Some board members suggested rates may need to reach 1% to control inflation.
The decision marked a significant shift from a decade-long stimulus program.
Analysts are skeptical about the BOJ's bullish economic projections.
The move has caused fluctuations in global markets and a spike in the yen.
