The Bank of Japan decided to keep its monetary policy unchanged Friday, despite strong pressure earlier in the week from politicians and the Finance Ministry for further easing.

The BOJ decided to keep target bank reserves at the central bank at 5 trillion yen during its regular two-day Policy Board meeting, which ended Friday.

Since March, the central bank has been pursuing an ultraloose policy, which pushes overnight interest rates down toward zero by making sure that banks hold large reserves of surplus funds.
