Bank of Japan kicks off meeting, unemployment falls slightly

In economic news, the Bank of Japan started its two-day monetary policy meeting on Tuesday, with significant anticipation surrounding potential adjustments to its monetary policy.

Economists surveyed by Reuters predicted that the central bank would increase its benchmark interest rate to 0.1%, a shift from the current range of 0% to 0.1%.

Additionally, the BoJ was expected to reduce its purchases of Japanese government bonds, signalling a potential tightening of its accommodative stance.

At the same time, Japan's unemployment rate saw a slight improvement in June, dropping to 2.5% from 2.6% in May.

The reading also came in just below the 2.6% forecasted by analysts, indicating a marginally stronger labour market than anticipated.
