Bank of Japan's (BOJ) loose monetary policy has boosted corporate fund demand and companies' spending appetite, Deputy Governor Amamiya said on Thursday.

The central bank has been running a massive stimulus program since 2013. As of now, BOJ's interest rate stands at -0.10% and the bank maintains the 10-year target of 0.00%. Even so, the economy remains miles away from BOJ's inflation target of 2%.
