The Finance Ministry said Monday it will raise the rate charged on lending to governmental financial institutions under the "zaito" fiscal investment and loan program from 1.9 percent to 2 percent.
The new rate will become effective Friday.
The ministry said it will also increase the interest rate on zaito funds deposited with the ministry's Trust Fund Bureau from 1.9 percent to 2 percent.
The move is in line with the raising of the nominal interest rate on 10-year government bonds issued for September, ministry officials said.
It marks the first time in five months that rates on zaito lending and deposits have been raised.
The zaito program is often dubbed the nation's second budget, due to its size.
