The Bank of Japan is expected to raise its key interest rate to a 30-year high on Tuesday, with a wait-and-see approach giving way to a certain sense of urgency.??

¡°I¡¯d say a rate hike is pretty much a done deal,¡± said Tsuyoshi Ueno, executive research fellow at NLI Research Institute.??

Inflation and a weak yen are pushing the central bank to take the rate to 1% from 0.75%, analysts said. It was last at the 1% level in 1995.
